  1. The 2px reading-progress line (#eqp-rail) sat 24px below the top of the window,\n      because the block layout gives every child of the post a 24px top margin. It\n      crossed the text like a strikethrough. It now sits at the very top.\n   2. Phone: text inside boxes (evidence boxes, \"worth being clear about\", panels)\n      stayed at the fluid minimum, 14.6px, while plain paragraphs are lifted to 17px\n      by the eq-phone-fixes rule (which only reaches direct children). Figures keep\n      their own sizes.\n   3. Tablet (641 to 899px, and any touch screen above that): contents rows get the\n      same 44px tap height the phone rows already have (they were 19 to 26px),\n      including the part rows with no sub-items (.flat). *\/\n#eqp-rail{margin:0!important}\n@media (max-width:640px){\n  body.single-post .eqp .has-background p[style*=\"21px)\"]:not(figure p){font-size:17px!important;line-height:1.62!important}\n}\n@media (min-width:641px) and (max-width:899px),(min-width:641px) and (hover:none){\n  body .eqp .eq-toc li{margin:0}\n  body .eqp .eq-toc li a{display:block;box-sizing:border-box;min-height:44px;padding:10px 0}\n  body .eqp .eq-toc summary .ttl{padding:11px 0;margin:-11px 0}\n  body .eqp .eq-toc .flat > a{display:flex;align-items:center;box-sizing:border-box;min-height:44px}\n}\n\/* 13 Oct, Luka approved:\n   4.

It won\u2019t tell you what your cortisol is, because nobody can see that from the outside, and an app can\u2019t either. If you\u2019d rather read it in shorter, everyday language, there\u2019s a switch near the top that gives the same main points in plain words.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">This is health information, not a diagnosis.<\/p>\n\n\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-container-core-group-is-layout-d2a766d4 wp-block-group-is-layout-constrained\">\n\n\n<div class=\"wp-block-group has-background has-global-padding is-layout-constrained wp-container-core-group-is-layout-83938ec0 wp-block-group-is-layout-constrained\" style=\"background-color:#faebe8;border-color:#e8bab0;border-width:1.5px;border-style:solid;border-radius:14px;margin-top:40px;margin-bottom:0;padding:34px 38px\">\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#a63f2c;margin-top:0;margin-bottom:12px;font-size:12px;font-weight:700;letter-spacing:0.16em;line-height:1.4\">THE SHORT VERSION<\/p>\n\n\n\n<div style=\"margin-top:0px;margin-bottom:0px\"><div class=\"cx-sv\"><ul class=\"rows cx-svn\"><li><a href=\"#part-1\"><span class=\"d\" aria-hidden=\"true\"><\/span><span class=\"tx\"><strong class=\"eqb\">Cortisol does far more than respond to stress: it follows a daily rhythm, steadies your blood sugar, keeps inflammation in check and helps you wake up, and too little is as dangerous as too much.<\/strong><\/span><svg class=\"ar\" viewBox=\"0 0 16 16\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.7\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\" focusable=\"false\"><path d=\"M2.5 8h10M8.5 3.5 13 8l-4.5 4.5\"\/><\/svg><\/a><\/li><li><a href=\"#part-2\"><span class=\"d\" aria-hidden=\"true\"><\/span><span class=\"tx\">It\u2019s highest soon after you wake and lowest around midnight; poor sleep, light, shift work and age bend the curve, though mostly by modest amounts.<\/span><svg class=\"ar\" viewBox=\"0 0 16 16\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.7\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\" focusable=\"false\"><path d=\"M2.5 8h10M8.5 3.5 13 8l-4.5 4.5\"\/><\/svg><\/a><\/li><li><a href=\"#part-3\"><span class=\"d\" aria-hidden=\"true\"><\/span><span class=\"tx\">Long stress doesn\u2019t reliably mean high cortisol, because some people under long stress have low cortisol, and the link with depression is real but smaller than the headlines.<\/span><svg class=\"ar\" viewBox=\"0 0 16 16\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.7\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\" focusable=\"false\"><path d=\"M2.5 8h10M8.5 3.5 13 8l-4.5 4.5\"\/><\/svg><\/a><\/li><li><a href=\"#part-4\"><span class=\"d\" aria-hidden=\"true\"><\/span><span class=\"tx\">\u201cCortisol face\u201d is a real sign of one rare condition and not of everyday stress; adrenal fatigue isn\u2019t a recognized diagnosis; cocktails, detoxes and most supplements have little or no good evidence; and ashwagandha\u2019s safety is disputed.<\/span><svg class=\"ar\" viewBox=\"0 0 16 16\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.7\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\" focusable=\"false\"><path d=\"M2.5 8h10M8.5 3.5 13 8l-4.5 4.5\"\/><\/svg><\/a><\/li><li><a href=\"#part-5\"><span class=\"d\" aria-hidden=\"true\"><\/span><span class=\"tx\">One cortisol number says little: doctors use specific tests for specific questions, and the time of day, the pill and pregnancy all move the number.<\/span><svg class=\"ar\" viewBox=\"0 0 16 16\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.7\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\" focusable=\"false\"><path d=\"M2.5 8h10M8.5 3.5 13 8l-4.5 4.5\"\/><\/svg><\/a><\/li><li><a href=\"#part-6\"><span class=\"d\" aria-hidden=\"true\"><\/span><span class=\"tx\">The real cortisol conditions are rare and treatable, and the most common one starts with steroid tablets, which is why long-term steroids should never be stopped suddenly.<\/span><svg class=\"ar\" viewBox=\"0 0 16 16\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.7\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\" focusable=\"false\"><path d=\"M2.5 8h10M8.5 3.5 13 8l-4.5 4.5\"\/><\/svg><\/a><\/li><li><a href=\"#part-7\"><span class=\"d\" aria-hidden=\"true\"><\/span><span class=\"tx\">What helps is ordinary: sleep, movement, people, time outside, slow breathing and therapy.

The signal to make it starts in the brain, in a chain that runs from a small control center at the base of the brain, the hypothalamus, to the pituitary gland, which releases <span class=\"eq-term\" tabindex=\"0\" aria-describedby=\"gd-2\">ACTH<span class=\"eq-def\" role=\"tooltip\" id=\"gd-2\"><b>ACTH<\/b>A hormone from the pituitary gland, at the base of the brain. It tells the adrenal glands to make cortisol.<\/span><\/span>, and from there to the adrenal glands. Our article <a class=\"xl\" href=\"\/your-brain-on-stress\/\">Your Brain on Stress<\/a> shows how this slow chain sits beside the fast, adrenaline-driven one.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Cortisol doesn\u2019t arrive in a steady drip. It\u2019s released in pulses, roughly once an hour, and the daily pattern comes from how big those pulses are.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"what-it-does-when-you-arent-stressed\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">What it does when you aren\u2019t stressed<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Think about what your body needs on an ordinary Tuesday. Cortisol is at work in at least four places.<\/p>\n\n\n\n<ul class=\"wp-block-list has-text-color has-work-sans-regular-font-family\" style=\"color:#2a2622;margin-top:0;margin-bottom:30px;font-size:clamp(14px, 0.875rem + ((1vw - 3.2px) * 0.682), 20px);line-height:1.7\">\n<li><strong class=\"eqb\">Energy and blood sugar.<\/strong> Cortisol tells your liver to make sugar and makes muscle and fat a little less responsive to insulin, which keeps sugar available for your brain between meals. A little of this goes on every day. Too much for too long raises blood sugar, as part six explains.<\/li>\n\n\n\n<li><strong class=\"eqb\">Inflammation and defense.<\/strong> Cortisol is part of how your body turns inflammation back down once it has done its job, which is why cortisol-like medicines have been used against inflammation since 1948.<\/li>\n\n\n\n<li><strong class=\"eqb\">Blood pressure and fluid balance.<\/strong> Cortisol helps keep your blood pressure steady. You notice that job mostly when it goes wrong: too much raises blood pressure, and too little lets it fall, which makes people dizzy when they stand up.<\/li>\n\n\n\n<li><strong class=\"eqb\">Sleep and waking.<\/strong> Cortisol is lowest in the first half of the night, starts climbing before you wake and gets an extra push just after. It\u2019s part of how your body gets you going, as part two shows.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">It also touches bone, muscle, mood and growth, and you tend to meet those jobs only when something goes wrong. One more detail: under long stress, the cells that respond to cortisol can start responding less. In two studies in which volunteers were exposed to a cold virus, that went with more colds in the first and more inflammatory signals in the second. So the familiar story, that stress means too much cortisol and therefore more inflammation, is simpler than the research is.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"why-stress-hormone-is-only-part-of-the-story\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Why \u201cstress hormone\u201d is only part of the story<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">The nickname has some truth in it, and four things missing.<\/p>\n\n\n\n<ul class=\"wp-block-list has-text-color has-work-sans-regular-font-family\" style=\"color:#2a2622;margin-top:0;margin-bottom:30px;font-size:clamp(14px, 0.875rem + ((1vw - 3.2px) * 0.682), 20px);line-height:1.7\">\n<li><strong class=\"eqb\">It has a rhythm without any stress.<\/strong> Part two draws it.<\/li>\n\n\n\n<li><strong class=\"eqb\">Plenty of things that raise it aren\u2019t stressful.<\/strong> Waking up, bright morning light, exercise and a cup of coffee all do.<\/li>\n\n\n\n<li><strong class=\"eqb\">It doesn\u2019t rise for every stressor.<\/strong> In more than 200 lab studies, it went up mainly when a task felt out of the person\u2019s control or when other people could judge how they did, and the biggest, longest rises came when both were true.<\/li>\n\n\n\n<li><strong class=\"eqb\">Too little is dangerous.<\/strong> Without enough cortisol, the body can\u2019t cope with illness or injury, and it can be life-threatening (part six). Hydrocortisone, the medicine, is cortisol, and people with Addison\u2019s disease take it for life. That\u2019s one reason a \u201ccortisol detox\u201d would be the wrong goal for anybody.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Adrenaline often gets mixed up with cortisol, so here is the difference. Adrenaline comes from the inner part of the same glands and is out within seconds: it\u2019s the pounding heart and the sudden alertness. Cortisol comes from the outer layer, rises over minutes and acts for hours. Adrenaline is the sprint, and cortisol is the supply line that keeps you stocked afterward.<\/p>\n\n\n<\/div>\n\n\n\n<div class=\"wp-block-group cx-keep has-global-padding is-layout-constrained wp-container-core-group-is-layout-d12c95ff wp-block-group-is-layout-constrained\">\n\n\n<aside class=\"cx-kp\"><span class=\"mk\" aria-hidden=\"true\"><svg viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.7\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\" focusable=\"false\"><path d=\"M7 4.5h10a1 1 0 0 1 1 1V20l-6-4.2L6 20V5.5a1 1 0 0 1 1-1z\"\/><\/svg><\/span><p class=\"k\">Worth remembering<\/p><p class=\"t\">Cortisol runs on a daily rhythm that has nothing to do with stress, and stress is one of several things that also move it.

It sat below its daily average from about a quarter to eight in the evening until half past five the next morning. That\u2019s one small group, so take the numbers as the shape of a healthy day and not as a target to hit.

Researchers still aren\u2019t sure what it\u2019s for; one idea is that it prepares you for the day ahead. Morning light helps push it up (more under \u201cWhat bends the curve\u201d).

A larger review of 24 studies, though, found no significant overall change after one short night, so the nudge is modest and doesn\u2019t show up every time. Years of short sleep went with a flatter daily pattern in a large group of British civil servants. Our article <a class=\"xl\" href=\"\/surprisingly-busy-business-of-sleeping\/\">The Surprisingly Busy Business of Sleeping<\/a> covers the sleep side, including what caffeine does to it.<\/li>\n\n\n\n<li><strong class=\"eqb\">Light.<\/strong> In a small, old study, an hour of bright light after waking raised the morning rise by about a third, while the same light in the late evening did nothing.<\/li>\n\n\n\n<li><strong class=\"eqb\">Shift work.<\/strong> Night work moves and disrupts the curve, and studies disagree about how far people adapt. Sleeping through the day doesn\u2019t switch cortisol down the way night sleep does, and timed bright light and darkness moved the peak toward a night schedule in a small group of night-shift workers.<\/li>\n\n\n\n<li><strong class=\"eqb\">Jet lag.<\/strong> After a long flight east across more than five time zones, travelers\u2019 cortisol stayed on home time for a while: higher than usual late in the evening and lower in the morning.<\/li>\n\n\n\n<li><strong class=\"eqb\">Meal timing.<\/strong> A weak lever. In a small study, pushing meals back by five hours for six days shifted blood sugar rhythms but not cortisol, so \u201ceat at this hour to fix your cortisol\u201d has no good support yet.<\/li>\n\n\n\n<li><strong class=\"eqb\">Age.<\/strong> Between 20 and 80, average cortisol rose by 20 to 50%, the night-time low rose, and the swing between day and night got smaller and earlier.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Caffeine and exercise nudge it too, and part four covers both.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"what-a-flat-curve-does-and-doesnt-mean\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">What a flat curve does and doesn\u2019t mean<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Researchers have also looked at the slope of the day\u2019s curve, meaning how steeply it falls from morning to night. Across 80 studies, a flatter slope went with poorer health on average, but the link was small. In just over 4,000 British civil servants, a flatter slope predicted dying from any cause over the years of follow-up.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">What nobody knows is whether a flat slope causes harm or only marks it. As far as we could find, no trial has shown that changing the slope changes health, no guideline uses a person\u2019s slope to diagnose anything, and working it out from a few saliva samples at home is shaky. So a flat curve on a home kit isn\u2019t a diagnosis of anything.<\/p>\n\n\n<\/div>\n\n\n\n<div class=\"wp-block-group cx-keep has-global-padding is-layout-constrained wp-container-core-group-is-layout-d12c95ff wp-block-group-is-layout-constrained\">\n\n\n<aside class=\"cx-kp\"><span class=\"mk\" aria-hidden=\"true\"><svg viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.7\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\" focusable=\"false\"><path d=\"M7 4.5h10a1 1 0 0 1 1 1V20l-6-4.2L6 20V5.5a1 1 0 0 1 1-1z\"\/><\/svg><\/span><p class=\"k\">Fun fact<\/p><p class=\"t\">Your cortisol starts rising before you wake, then adds an extra push in the first half hour after you\u2019re up.

It doesn\u2019t mean cortisol causes depression, and a cortisol test can\u2019t show it.

You rehearse, you check the time, and your body is clearly doing something. Then it\u2019s over and your system settles. Now think of the same body a year into low-grade strain: a job that never lets up, a money worry that comes back every month. Those are two very different situations for a stress system, and cortisol doesn\u2019t behave the same way in both.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"a-short-spike-is-the-system-working\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">A short spike is the system working<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">In the lab, a stressful task makes cortisol rise, peak and then come back down. That\u2019s the system doing its job: short rises help the body mobilize, and it\u2019s long exposure that turns costly. Recovery is slowest when the situation is both out of your control and judged by other people.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"long-stress-isnt-one-thing\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Long stress isn\u2019t one thing<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">You might expect long stress to mean a body soaked in cortisol. The research is less tidy. In a <span class=\"eq-term\" tabindex=\"0\" aria-describedby=\"gd-3\">meta-analysis<span class=\"eq-def\" role=\"tooltip\" id=\"gd-3\"><b>meta-analysis<\/b>A study of studies. It pools the results of many separate studies of one question, which gives a steadier answer than any single study can.<\/span><\/span> of the human studies, cortisol was raised when a stressor started and then declined as time went by.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Stressors that threatened physical safety, involved trauma or couldn\u2019t be controlled produced a high, flat daily pattern, and people with PTSD tended to have lower output. Hair, which stores cortisol over months, tells a similar story: people who were still living with a stressor had hair cortisol roughly 40% higher, while people whose stress had passed did not.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"depression-a-real-link-smaller-than-the-headlines\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Depression: a real link, smaller than the headlines<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Depression is the diagnosis most often tied to cortisol. People with depression have higher cortisol on average, but the difference shrinks by nearly half when only the studies that met basic standards are counted. In teenagers and young adults, higher morning cortisol came before depression and didn\u2019t differ once it had started, which points to a risk factor and not a marker of current illness. So the link is real, it\u2019s smaller than the headlines make it, and you can\u2019t see depression in a cortisol test. Nothing here says cortisol causes it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"some-conditions-show-low-cortisol\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Some conditions show low cortisol<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">At the other end, some people under long stress have lower cortisol than usual. In PTSD, morning and 24-hour cortisol were lower on average than in people without it, though not in every study. Burnout is a word to handle carefully. The World Health Organization\u2019s ICD-11 calls it an occupational phenomenon and not a medical condition, and reviews haven\u2019t found a reliable cortisol marker for it. A smaller morning rise has also been found in chronic fatigue syndrome. One idea, and so far only an idea, is that low cortisol can follow a long stretch of high output.

Doctors call it moon face. Studies of faces in Cushing\u2019s find a real pattern, with fat settling toward the cheeks and lower face.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">What nothing supports is the idea that everyday stress does it. Cushing\u2019s is rare (part six), steroid medicine is its most common cause, and doctors don\u2019t diagnose it from a rounder face alone. They look for several signs together, such as easy bruising, a pad of fat over the upper back and high blood pressure. Many ordinary things change how a face looks from one day to the next, including sleep, salt, alcohol, allergies and aging.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">If you find yourself checking your face in the mirror for signs, that\u2019s worth telling someone. It\u2019s a good reason to talk, and it isn\u2019t a reason to buy anything.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"cortisol-belly\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">\u201cCortisol belly\u201d<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">There\u2019s a small grain of truth here. In Cushing\u2019s, fat gathering around the middle is a hallmark. In everyone else, long-term cortisol (measured in hair) goes with body size only slightly, and nobody knows which way it runs: whether cortisol changes the body or the body changes cortisol. A study of several hundred adults with overweight or obesity found that cortisol didn\u2019t track weight, and the authors concluded the data don\u2019t support a strong link between cortisol or stress and obesity. There\u2019s no cortisol plan that targets belly fat, and weight changes for many reasons.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"adrenal-fatigue\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">\u201cAdrenal fatigue\u201d<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">The idea is that years of stress wear out the adrenal glands, causing tiredness, cravings and brain fog, which a saliva panel can show and a supplement can fix. The Endocrine Society, a US professional body for hormone specialists, says there\u2019s no scientific proof that adrenal fatigue is a real medical condition and no test that detects it, and that the tests some providers use aren\u2019t backed by solid research. A review of 58 studies reached the same place: it found no substantiation. Supplements sold for it can do harm, too. Adrenal hormones taken when they aren\u2019t needed can suppress the adrenal glands and risk an adrenal crisis when they are stopped (part six).<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">None of that makes the tiredness less real. Tiredness that has gone on for weeks deserves a proper look from a doctor, because the explanations the Endocrine Society and the UK\u2019s national health service list include adrenal insufficiency, depression, sleep apnea and thyroid disease.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"cortisol-cocktails-and-detoxes\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Cortisol cocktails and detoxes<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">A \u201ccortisol cocktail\u201d is a drink, often orange juice and coconut water with a pinch of salt and sometimes magnesium, that\u2019s said to balance your adrenals. We found no controlled trial of it. Dietitians and doctors quoted in news pieces say there are no clinical data behind it and that at best it supplies fluid and salts. If you like the taste, it\u2019s a drink. And the idea it rests on, that your adrenals are worn out, hasn\u2019t held up.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">A \u201ccortisol detox\u201d fails for a different reason. Cortisol isn\u2019t a toxin: your body needs it for blood pressure, blood sugar and energy, and it\u2019s meant to be highest in the morning and lowest at night. A critical review of detox diets in general found little clinical evidence for them and no randomized trials of the commercial ones. Products promising to control cortisol have been sold on similar promises for more than twenty years. By 2007 the US Federal Trade Commission had settled with the makers of two of them over false and unproven claims about weight loss and disease prevention.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"supplements\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Supplements<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Ashwagandha is the one most readers meet, so it gets the most space. Many people say it helps them feel calmer, and that deserves to be taken seriously, because calm is what they were after.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">What the trials show is more mixed. In short trials it lowered a lab measure of cortisol by a small amount. But in a 2025 meta-analysis of seven trials, people\u2019s own ratings of how stressed they felt didn\u2019t change significantly, even though cortisol did, while an earlier review of nine trials had found lower stress and anxiety scores as well. Many of the trials were small, and we didn\u2019t check who paid for them. Put together, that\u2019s a modest effect on a lab number and an unclear effect on how people feel.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">The bigger question is safety, and that is disputed. There are reports of serious liver injury in people who took it: in one series from Iceland and the US, five people developed jaundice within weeks (none went into liver failure, tests returned to normal in four, and one was lost to follow-up), and in a series from India, three people who already had long-term liver disease died. Case reports can\u2019t say how often this happens.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Germany\u2019s federal risk assessment institute advises children, pregnant and breastfeeding women and people with liver disease not to take ashwagandha supplements, says others should be cautious, and says it couldn\u2019t set a safe intake. Denmark banned it in food supplements in 2023, and the Netherlands, France, Australia and the UK have reviewed it or issued warnings. Some researchers in the Ayurvedic field say the Danish report was flawed and that no causal link to liver injury has been shown. As of October 2026, we found no decision from the European Union as a whole.<\/p>\n\n\n<\/div>\n\n\n\n<div class=\"wp-block-group cx-keep has-global-padding is-layout-constrained wp-container-core-group-is-layout-d12c95ff wp-block-group-is-layout-constrained\">\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family cx-keep wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">If you have liver disease or a thyroid condition, if you\u2019re pregnant or breastfeeding, or if you take regular medicine, especially for blood pressure or diabetes or to suppress the immune system, talk to a pharmacist or doctor before taking ashwagandha.<\/p>\n\n\n<\/div>\n\n\n\n<div class=\"wp-block-group cx-n has-global-padding is-layout-constrained wp-container-core-group-is-layout-d12c95ff wp-block-group-is-layout-constrained\">\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">The other names that come up are phosphatidylserine, magnesium, L-theanine and rhodiola. They have little or no good evidence for lowering cortisol itself. Some have small trials for anxiety or tiredness, usually without a cortisol measure. Magnesium, for example, looked suggestive for anxiety in people prone to it, but the studies were of poor quality, and that review looked at how anxious people felt, not at cortisol. In the US, the Food and Drug Administration doesn\u2019t oversee supplements the way it does medicines, so what is on a label may not match what is in the bottle.<\/p>\n\n\n<\/div>\n\n\n\n<div class=\"wp-block-group cx-keep has-global-padding is-layout-constrained wp-container-core-group-is-layout-d12c95ff wp-block-group-is-layout-constrained\">\n\n\n<aside class=\"cx-kp\"><span class=\"mk\" aria-hidden=\"true\"><svg viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.7\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\" focusable=\"false\"><path d=\"M7 4.5h10a1 1 0 0 1 1 1V20l-6-4.2L6 20V5.5a1 1 0 0 1 1-1z\"\/><\/svg><\/span><p class=\"k\">Be mindful<\/p><p class=\"t\">A supplement that lowers a lab number hasn\u2019t been shown to make you feel better.

A single session of moderate to hard exercise does raise cortisol, more the harder you go, and a gentle one barely moves it. The rise is brief and normal, and trained bodies adapt. Across ten studies of physical activity programs, cortisol went down on average and sleep got better. An expert consensus statement says no hormonal marker, cortisol included, can diagnose overtraining. So \u201ccardio raises cortisol\u201d is true for a few minutes and is no reason to skip it. If you feel exhausted from training, rest matters, and a cortisol test isn\u2019t how to find out.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"coffee\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Coffee<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Coffee raises cortisol for a while after you drink it.

Doctors use different tests for different questions. When they suspect too much cortisol, they use a late-night saliva test, a 24-hour urine test or a dexamethasone test (a small dose of a steroid medicine at night, then blood taken the next morning). When they suspect too little, they use an ACTH test, which checks whether the adrenal glands respond to ACTH, the hormone that tells them to make cortisol. These tests are very good at telling the difference in people who have been sent for testing.

So whether a reading counts as high or low depends on when and how it was taken. Try the slider in Figure 1: pick a time of day and watch the same body give very different numbers. A doctor does order a morning blood cortisol, for a specific reason, such as checking whether your adrenal glands have recovered after steroid medicine. It\u2019s a tool for a question and not a score for stress.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"what-doctors-actually-use\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">What doctors actually use<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Doctors use different tests for different questions, and knowing the names helps if you ever need to ask for the right one.<\/p>\n\n\n<\/div>\n\n\n\n<div class=\"wp-block-group cx-n has-global-padding is-layout-constrained wp-container-core-group-is-layout-d12c95ff wp-block-group-is-layout-constrained\">\n\n\n<div style=\"margin-top:6px;margin-bottom:10px\"><table class=\"cx-tb\"><caption>The tests doctors use, in plain words<\/caption><thead><tr><th>The question<\/th><th>The test<\/th><th>What it involves<\/th><\/tr><\/thead><tbody><tr><td class=\"q\">Is the body making too much cortisol?<\/td><td class=\"t\"><span>Late-night saliva sample<\/span><span>24-hour urine collection<\/span><span>Dexamethasone suppression test<\/span><\/td><td>Cortisol should be at its lowest late at night, so a saliva sample then is telling.

That\u2019s why they are trusted, and why a second test usually confirms the first. No cut-off numbers are quoted here, because they differ between labs. Testing is for suspected Cushing\u2019s or adrenal insufficiency and is ordered by a doctor. Stress on its own isn\u2019t diagnosed by a cortisol test.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"hair-cortisol\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Hair cortisol<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Cortisol is also stored in hair, and a few centimeters of it show roughly the past few months. In research it picks up long stress exposure, with hair cortisol about a fifth higher in stress-exposed groups. But it needs adjusting for age, sex, hair washing, hair treatments and the pill, and it remains mainly a research tool, though clinics are starting to use it for rare conditions in which cortisol rises and falls in cycles.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"home-kits\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Home kits<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Mail-order saliva, urine and hair kits promise to show your cortisol pattern, your adrenal health or your stress level. We found no peer-reviewed check of any mail-order panel. The one peer-reviewed validation we found, of a portable saliva device, agreed only moderately with lab results and read low at rest. The morning surge needs samples timed strictly from waking, which most studies fail to manage. The Endocrine Society (US) says the tests some providers use for \u201cadrenal fatigue\u201d aren\u2019t backed by solid research. A kit can\u2019t tell you what to do. If you\u2019re worried about a hormone problem, the route is the doctor\u2019s tests above.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"why-your-number-isnt-mine\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Why your number isn\u2019t mine<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Two healthy people can have different cortisol for ordinary reasons. Sex and age shift averages a little: in one large Swedish study women had higher morning cortisol than men, and cortisol tends to creep up with age. Hard early experiences leave a small and inconsistent mark, nowhere near enough to read a history from a number. Genes play a part too, though no single common gene variant explains much.<\/p>\n\n\n<\/div>\n\n\n\n<div class=\"wp-block-group cx-pl has-global-padding is-layout-constrained wp-container-core-group-is-layout-d12c95ff wp-block-group-is-layout-constrained\">\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family cx-plk wp-block-paragraph\" style=\"color:#a63f2c;margin-top:38px;margin-bottom:14px;font-size:12px;font-weight:700;letter-spacing:0.16em;line-height:1.4\">In plain words<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:8px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">The pill and estrogen tablets raise the total cortisol in a blood test without changing how your body works.

Most of the cortisol in your blood rides on a carrier protein, and only the unattached, or free, part is active.

The most common cause is steroid medicine, taken as tablets and sometimes in high doses by other routes. The much rarer kind starts in the body itself, most often with a small tumor on the pituitary gland and less often on an adrenal gland. In European registries it appears in about two or three people per million per year, and most of the data come from Europe, with little from the rest of the world.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">It comes on gradually. Doctors look for a group of signs that build over months or years, such as easy bruising, wide purple stretch marks, muscle weakness and high blood pressure, along with the changes in the face and middle that people talk about online. Each sign on its own has many other causes. It matters to find, because it\u2019s linked with high blood pressure, diabetes and weaker bones, and it\u2019s treatable: usually by treating its cause, which is often surgery for a tumor, or by gradually reducing a steroid medicine under a doctor. The tests are in part five.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"the-common-one-steroid-medicines\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">The common one: steroid medicines<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">This is the part of the story that reaches the most people. About 1 in 100 adults takes steroid medicine for a long time. Steroid medicines are cortisol-like drugs, also called corticosteroids or glucocorticoids. While you take them, your body senses plenty of cortisol-like hormone and turns down its own production. After weeks of tablets the adrenal glands may be switched off, and for a while after you stop they may not restart fully. It can happen with steroid injections too, and less often with inhalers, nasal sprays and creams.

Ask the prescriber or pharmacist how to come down in steps, which is called tapering. Courses shorter than three weeks usually don\u2019t need tapering, but ask, especially after a high dose or several courses close together. If you were given a steroid card, keep it with you. If you take steroids for a long time, or stopped them recently, ask your prescriber what to do if you get ill with a fever, vomiting or diarrhea, and tell any doctor, dentist or surgeon who treats you about them.<\/p>\n\n\n<\/div>\n\n\n\n<div class=\"wp-block-group cx-n has-global-padding is-layout-constrained wp-container-core-group-is-layout-d12c95ff wp-block-group-is-layout-constrained\">\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Coming off steroids can feel rough, and the feelings of withdrawal overlap with those of low cortisol, so working out which is which is a job for a doctor and not for guessing. How fast the adrenal glands recover varies a great deal from person to person. The guideline suggests seeing an endocrinologist, a hormone specialist, if there\u2019s no recovery after a year on a low replacement dose, or after an adrenal crisis.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"too-little-addisons-disease-and-adrenal-insufficiency\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Too little: Addison\u2019s disease and adrenal insufficiency<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Adrenal insufficiency means the body doesn\u2019t make enough cortisol. When the adrenal glands themselves are the problem, it\u2019s called Addison\u2019s disease, and in richer countries it\u2019s usually autoimmune, which means the immune system attacks the glands. When the pituitary gland doesn\u2019t send enough ACTH, it\u2019s called secondary, and steroid medicine is one of its leading causes. In Iceland, about 22 in every 100,000 adults had Addison\u2019s disease, more than older reports suggested. Most of the data on this come from Europe.<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Because it begins with ordinary-sounding things like lasting tiredness, adrenal insufficiency is often diagnosed late. The help box below says which combination is worth a visit. It\u2019s treatable. People take daily hydrocortisone and, with Addison\u2019s disease, a second medicine called fludrocortisone, take extra doses when they are ill or having surgery, carry a steroid card, and many have an emergency injection and training in how to use it. With treatment, people live normal lives.<\/p>\n\n\n<\/div>\n\n\n\n<div class=\"wp-block-group cx-pl has-global-padding is-layout-constrained wp-container-core-group-is-layout-d12c95ff wp-block-group-is-layout-constrained\">\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family cx-plk wp-block-paragraph\" style=\"color:#a63f2c;margin-top:38px;margin-bottom:14px;font-size:12px;font-weight:700;letter-spacing:0.16em;line-height:1.4\">In plain words<\/p>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:8px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Addison\u2019s disease and other kinds of adrenal insufficiency start with ordinary-sounding things like lasting tiredness, so they are often found late.

In a survey of 444 people with adrenal insufficiency, 42% had had at least one crisis, and the most common trigger was a stomach infection or fever.

We found no trial that shows that. Sleep still earns its place on this list, because it\u2019s tied to nearly everything else, including mood and memory.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"movement\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Movement<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">The World Health Organization recommends 150 to 300 minutes of moderate activity a week for adults, or 75 to 150 minutes of vigorous activity, plus muscle-strengthening. In ten studies of activity programs, cortisol came down by a small to moderate amount and sleep improved. How movement helps mood, anxiety and sleep is in our article <a class=\"xl\" href=\"\/exercise-and-mental-health\/\">Motion and Emotion<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"people-and-touch\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">People and touch<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">In one lab study, men who had their best friend with them before a stressful task had a smaller cortisol rise, and a smaller one still when they also had oxytocin, a hormone linked to bonding. In another, a hug or a hand held over the heart lowered cortisol after a stressful task in 159 adults, even though their heart rate and their own ratings of stress didn\u2019t differ. These are small lab effects, so we don\u2019t know yet how much of this carries into daily life.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"time-in-nature\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Time in nature<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Cortisol was lower after time in forests than in cities in a pooled analysis of eight studies, though expectation may play a part. In a study of 36 city dwellers, a nature break of 10 minutes or more lowered cortisol, most efficiently at 20 to 30 minutes. The effect is small and short-lived, and the second study had no comparison group.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-work-sans-regular-font-family\" id=\"breathing-mindfulness-and-yoga\" style=\"color:#211a17;margin-top:64px;margin-bottom:16px;font-size:clamp(15.197px, 0.95rem + ((1vw - 3.2px) * 0.887), 23px);font-style:normal;font-weight:700;line-height:1.28\">Breathing, mindfulness and yoga<\/h3>\n\n\n\n<p class=\"has-text-color has-work-sans-regular-font-family wp-block-paragraph\" style=\"color:#2a2622;margin-top:0;margin-bottom:26px;font-size:clamp(14.082px, 0.88rem + ((1vw - 3.2px) * 0.786), 21px);line-height:1.68\">Slow breathing reliably calms the body in the moment, but its effect on cortisol isn\u2019t established: one review found only three studies of belly breathing, all of them showing less stress, and one with lower saliva cortisol. Mindfulness, meditation and yoga did better, with small to moderate drops in cortisol across dozens of trials, though the results varied a lot.
