How to lower cortisol: what works, and what is just hype
How to lower cortisol with sleep, exercise, breathing and mindfulness, what supplements can do, why the cortisol cocktail fails, and signs to see a doctor.
The short answer
For most people, lowering cortisol means recovering from stress: cortisol is meant to rise and fall every day. Sleep, regular moderate exercise, slow breathing, mindfulness and good relationships have the best evidence. Ashwagandha lowered cortisol in small trials but carries a rare liver risk; the cortisol cocktail and cortisol-lowering foods have no evidence.
- Signs such as a round face, purple stretch marks and muscle weakness need a doctor, not self-care.
How to lower cortisol is mostly a question about how to recover from stress, because for most people cortisol is doing its job, not running out of control. Cortisol is meant to rise and fall every day. The habits that bring a stressed system back down are ordinary ones: sleep, movement, slower breathing and people you feel safe with. A few supplements have some evidence, most of the viral fixes have none, and genuinely abnormal cortisol is a medical condition that needs a doctor, not a drink.
What does cortisol actually do?
Cortisol is a hormone made by your adrenal glands, which sit on top of your kidneys. The Cleveland Clinic describes it as the body's main stress hormone, but it does much more than that: it helps regulate blood sugar, blood pressure, inflammation and your sleep-wake cycle. Levels normally peak soon after you wake, which helps you get up and going, and fall to their lowest around midnight. A rise during a stressful moment is normal and useful. The problem people mean when they search for this is a body that stays switched on: poor sleep, constant pressure and no real recovery, so the stress response never fully settles.
High cortisol symptoms, and when it is something else
Everyday stress and true high cortisol can share tiredness and poor sleep, but they are not the same thing. Persistently high cortisol from a medical cause, such as Cushing syndrome or long-term steroid medicine, brings specific physical signs that stress alone does not.
| Everyday stress | Medically high cortisol (Cushing syndrome) | |
|---|---|---|
| How common | Very common | Rare |
| Typical signs | Tired, wired, poor sleep, irritable, tense | Rounder face, fat above the collarbones, purple stretch marks, easy bruising, weak muscles, high blood pressure |
| What changes it | Sleep, rest, exercise, support, time | Medical treatment of the cause |
| Who to see | Self-care first; a GP if it lasts | A doctor, who can order blood, saliva or urine tests |
Our guide to cortisol face explains why a puffy face after a hard week is rarely a cortisol problem.
If you notice the signs in the right-hand column, especially together, see a doctor rather than trying to fix it yourself. The same goes for the opposite pattern, below. For the face side of the story, see what "cortisol face" really is.
What "low cortisol" means, and what it does not
"Low cortisol" has become a social media phrase for feeling calm and rested. Medically, low cortisol means something different: the adrenal glands not making enough, called adrenal insufficiency, which can cause exhaustion, weight loss, dizziness, low blood pressure and salt cravings. That is a medical condition that needs testing and treatment.
"Adrenal fatigue", the idea that stress wears the adrenal glands out, is not a recognised medical diagnosis. If you feel exhausted all the time, the useful step is a GP visit that can check for common causes such as anaemia, thyroid problems, sleep apnoea or depression.
How to lower cortisol: what works
| What to do | Why it helps | How strong the evidence is |
|---|---|---|
| Sleep 7 to 9 hours, at regular times | Short or broken sleep keeps cortisol higher; a steady schedule supports the daily rhythm | Strong |
| Regular moderate exercise | Improves sleep and stress resilience; very hard sessions raise cortisol briefly, then it settles | Strong |
| Slow breathing | Long, slow out-breaths switch on the body's rest-and-digest system | Moderate |
| Mindfulness or meditation | A meta-analysis of trials found a moderate fall in cortisol, from few studies | Moderate |
| Time with people you trust, and laughter | Close, easy relationships buffer stress | Moderate |
| Supplements | Some, such as ashwagandha, lowered cortisol in small trials | Limited; see below |

1. Protect your sleep
The Cleveland Clinic lists poor sleep, including shift work and insomnia, among the things that keep cortisol high. Regular bed and wake times matter as much as total hours, because cortisol follows a daily rhythm. Our guide to falling asleep faster covers the steps with the best evidence.
2. Move most days, not punishingly
Regular activity improves sleep and how you handle stress. A hard interval session raises cortisol for a while, which is a normal training response, not damage. If you are exhausted and sleeping badly, swap some intense sessions for walking, strength work or gentle routines such as our deep core exercises, and keep going.
3. Breathe slowly, on purpose
Controlled breathing helps switch on the parasympathetic nervous system, the "rest and digest" side. A simple version: breathe in through your nose for about four counts and out for about six, for five minutes. It is free, quick and works in a queue or before bed.
4. Practise mindfulness or meditation
A 2016 meta-analysis of mindfulness trials in healthy adults found a moderate reduction in cortisol, while noting that only a small number of studies were available. Treat it as a reasonable habit to try, not a guaranteed fix. Ten minutes a day is enough to start.
5. Spend time with people who are easy to be with
The Cleveland Clinic notes that tense, unhealthy relationships are a source of frequent stress, and that laughing helps release endorphins. Regular, low-pressure time with friends is one of the most reliable buffers there is.
Do supplements lower cortisol?
Some may, a little. The best-studied is ashwagandha. A 2025 meta-analysis of seven trials found that it lowered cortisol levels but did not significantly change how stressed people said they felt. All seven trials were run in India, with different doses. Ashwagandha has also been linked to rare cases of liver injury, so avoid it if you have liver problems, are pregnant or breastfeeding, or take thyroid medicine, and ask your doctor first.
Magnesium, omega-3, L-theanine and rhodiola appear on many "cortisol supplement" lists, but the evidence that they lower cortisol in healthy people is weak or mixed. If you are considering magnesium for sleep, our comparison of magnesium glycinate and citrate explains the forms.
The cortisol cocktail, and other viral fixes
The "cortisol cocktail" or "adrenal cocktail", usually orange juice, coconut water and a pinch of salt, has no studies showing that it lowers cortisol. It is a pleasant, mildly salty drink, and that is all. The same is true of "cortisol detox" plans and lists of cortisol-lowering foods: no single food meaningfully lowers cortisol. Regular, balanced meals help in the ordinary way, by keeping your energy and blood sugar steady.
Should you test your cortisol?
Only if a doctor suspects a medical cause. Cortisol changes so much through the day that a single reading, or a home saliva kit, says little on its own. When it matters, doctors use timed blood tests, late-night saliva tests or 24-hour urine collections, and interpret them alongside your symptoms. If you are simply stressed and tired, the first steps above are where to start.
General information, not medical advice. Talk to your doctor before starting a supplement, especially if you are pregnant, breastfeeding, take regular medicine or have a liver, thyroid or hormone condition.

Questions people ask about this
How can I lower my cortisol naturally?
Sleep 7 to 9 hours at regular times, exercise most days at a moderate level, practise slow breathing or mindfulness, and spend time with people who are easy to be with. These have the best evidence.
What are the symptoms of high cortisol in women?
Medically high cortisol, as in Cushing syndrome, can cause a rounder face, fat above the collarbones, purple stretch marks, easy bruising, muscle weakness and high blood pressure. Everyday stress does not cause these signs; see a doctor if you notice them.
What supplements lower cortisol?
Ashwagandha has the most evidence: a 2025 analysis of seven trials found lower cortisol, though no change in how stressed people felt. It has been linked to rare liver injury. Evidence for magnesium, omega-3 and others is weak.
Does the cortisol cocktail work?
There are no studies showing that the cortisol or adrenal cocktail lowers cortisol. It is a drink of juice, coconut water and salt, nothing more.
Is adrenal fatigue real?
It is not a recognised medical diagnosis. Persistent exhaustion has many real causes, such as anaemia, thyroid problems and sleep apnoea, which a GP can check for.
