On-line, cortisol—generally referred to as the “stress hormone”—is a sizzling matter and frequent scapegoat. Sort “cortisol ranges” or “howtoreducecortisol” into TikTok, and also you’ll be met with a whole bunch of thousands and thousands of posts, name-dropping the hormone as liable for every little thing from a puffy face (#cortistolface) to a bloated midsection. There are simply as many hacks for easy methods to deal with it. Magnificence and wellness manufacturers have additionally jumped on the cortisol bandwagon and launched merchandise, generally marketed as “anti-stress,” that declare to scale back cortisol.
Contemplating that stress has develop into a bogeyman for every little thing that ails us, it’s maybe not stunning that individuals are zeroing in on tamping down the hormone aligned with it. However what precisely is cortisol? Do we actually have to be fixated on our ranges? And when can we pretty blame it for well being points?
How cortisol works
The cortisol fixation has made its approach from the web to medical doctors’ places of work. And folks have questions. “In all my years of being a physician, I’ve by no means heard cortisol being talked about a lot by sufferers,” says Dr. Molly McBride, an ob-gyn and girls’s well being specialist in New York Metropolis. “Now with TikTok operating amok, all people is asking for cortisol checks.”
Cortisol is a hormone synthesized from ldl cholesterol that’s produced by the adrenal glands. Once we are confused or in fight-or-flight mode, the mind kicks off a course of that ends in the physique producing cortisol. “Cortisol then stimulates our physique to extend blood strain and metabolize fat, carbohydrates, and protein so we now have the power to reply to the stressor,” says Dr. David Kim, a dermatologist in New York Metropolis. Cortisol is important for regulating circadian rhythms and reacting to inner and exterior stressors. “It truly is an adaptive hormone,” crucial for our acute stress response and the restoration from it, says Rajita Sinha, a neuroscientist and professor of psychiatry at Yale College of Drugs. All of us have cortisol, in different phrases, and all of us want it.
The highs and lows of cortisol
It’s regular for cortisol ranges to rise and fall all through the day. This sample is known as the diurnal cycle, says Sinha: cortisol is highest within the morning, then plummets within the afternoon (which is why you may generally get a post-lunch power hunch). It’s decrease within the night, earlier than bedtime. Quick-term spikes assist us cope with bodily and emotional stressors—operating away from a tiger, say, or its modern-day equal, receiving a distressing work e-mail—which isn’t a nasty factor. “Cortisol triggers blood sugar so muscle mass have glucose to operate,” says Dr. Gillian Goddard, an endocrinologist in New York Metropolis. These fast bursts “enhance your alertness within the mind to make good selections.” Cortisol additionally goes up after we’re sick in an try to assist recruit the immune system.
When cortisol is regarding—and when it’s not
If cortisol stays elevated constantly, the blood-sugar spike it units off can result in weight achieve across the midsection. It could additionally preserve you up at evening; folks with persistently increased cortisol are inclined to have issues falling or staying asleep.
As a result of cortisol can have an effect on the dopamine and serotonin ranges within the mind, it could actually additionally have an effect on temper, and better ranges have been linked to mental-health situations like melancholy and anxiousness, says McBride.
Ranges may dip too low. When that occurs for an prolonged time frame, “it’s both as a result of the adrenal gland, which produces cortisol, is not getting the correct stimulation from the mind, or there’s one thing really incorrect with the adrenal gland,” says Dr. Caroline Messer, an endocrinologist in New York Metropolis. Very low cortisol ranges could cause signs together with weight reduction, fatigue, a scarcity of urge for food, and low blood strain and blood sugar, says Goddard.

Constantly excessive cortisol ranges are generally linked to sure illnesses. If cortisol is 2 to 4 instances increased than the conventional stage (which itself is variable) for too lengthy, it could actually trigger Sort 2 diabetes, Goddard says. In uncommon instances, excessive cortisol may be a sign of Cushing’s syndrome (brought on by a benign tumor within the pituitary gland). “The traditional image of Cushing’s is weight achieve within the midsection, skinny arms with muscular atrophy, darkish vast purple stretch marks on the stomach and thighs, sleep disruptions, and new onset temper adjustments like melancholy or anxiousness,” says Goddard. A big swollen face, irregular distribution of fats, and the event of a hump between the shoulders are extra indicators, says Kim.
Similar to cortisol, Cushing’s illness is much-discussed on social media. Medical doctors together with Goddard and Messer have extra sufferers, notably younger girls, asking to be examined for it greater than ever. “Lots of people are diagnosing themselves with Cushing’s after they don’t have it,” says Messer.
Calculating your cortisol ranges is difficult
At-home cortisol checks exist, however medical doctors doubt their accuracy and utility. Through the use of numerous blood, saliva, and urine checks, endocrinologists are finest outfitted to get a complete image of a affected person’s cortisol profile and what it means.
Earlier than testing, your particular cortisol-related subject must be outlined—“you possibly can’t simply be usually involved about your cortisol,” says Messer—and since ranges can shift all through the day, timing issues. Typically, to diagnose an issue, medical doctors need sufferers to verify their cortisol ranges late at evening (between 11 p.m. and midnight) and very first thing within the morning between 6 a.m. and eight a.m. Quite a lot of situations and drugs can impede the testing course of. For instance, “oral contraceptives can elevate cortisol ranges and mimic stress-like situations,” says McBride; sufferers who’re pregnant, present process menopause, or who’ve PCOS additionally usually have increased ranges, making testing tougher.
Generally the testing itself can pose an issue. “Even the act of drawing blood, if it’s one thing that makes you nervous, can increase your cortisol stage,” says Goddard. Your physician will work with you to get essentially the most correct outcomes.
Chopping by the noise
As name-checking cortisol has develop into extra commonplace, so have the misconceptions round it. Take “cortisol face,” the social-media moniker for facial puffiness supposedly linked to excessive cortisol. Excessive ranges of cortisol could cause irritation, elevated perspiration, and sebum manufacturing, which might result in pimples flare-ups, says Kim, however the bloating is usually attributable to conduct precipitated by stress. “Once we are confused, we snack extra and crave meals that tends to have increased salt and sugar content material that may result in bloating and swelling of the face,” says Kim.

As for the claims you could really really feel your cortisol spiking? Not attainable, specialists say. “You possibly can expertise signs related to elevated cortisol like rising coronary heart price, sweating, or anxiousness, however they aren’t particular to excessive cortisol,” says McBride.
Then there’s so-called adrenal fatigue, which refers to a notion that adrenal glands can burn out and develop into unable to supply cortisol. Medical doctors say it has no foundation in science. “It’s a colloquial time period, and there may be completely nothing in medical literature that helps it,” says Goddard. Plus, it’s physiologically unimaginable, says McBride. “As long as you’re consuming you will have some ldl cholesterol, you’re going to be making cortisol,” she says. “Adrenal fatigue has develop into a catchall time period for individuals who simply aren’t feeling nicely.”
Must you attempt to decrease your cortisol?
It’s vital to keep in mind that cortisol rises and falls; testing and monitoring it or taking dietary supplements that declare to handle it’s often pointless. “The concept the stress in our day-to-day lives is elevating our cortisol ranges to the purpose of inflicting long-term hurt is overstated,” says Goddard.
One of the best issues you are able to do to your cortisol are the identical stress-management ideas you already know: keep a balanced weight loss plan that’s low in sugar and refined carbohydrates, get sufficient relaxation, train commonly, and make leisure a behavior, whether or not by breathwork, meditation, short walks in nature, or one other confirmed tactic. “If participating in these actions makes folks really feel higher and fewer confused, that is nice,” says Goddard. “It doesn’t matter whether or not they really decrease cortisol ranges or not.”
