When you experience stress, your body releases hormones to help you adapt. One of these hormones is called cortisol. Part of the fight-or-flight response, cortisol helps keep you alert and healthy when facing stressors. It also regulates many other important bodily functions, such as blood sugar, metabolism, and your sleep-wake cycle.
While cortisol is an important part of healthy physical function, too much of it can have the opposite effect. High cortisol levels for a prolonged period of time may leave you feeling anxious on edge or tired and foggy due to lack of sleep. The good news: A few simple-but-effective lifestyle tweaks can help you better adapt to stress and support healthy cortisol levels.
In this article, learn more about what cortisol is, what can raise it to unhealthy coritsol levels, how it affects the body, and which daily habits may help lower cortisol and reduce overall stress.
Cortisol is a hormone made by your adrenal glands, which sit on top of your kidneys. Often called the stress hormone, cortisol is released during your body’s fight-or-flight response to help you manage the effects of stress — primarily to boost energy and keep you alert. This essential hormone helps regulate important bodily functions like inflammation, metabolism, blood pressure, blood sugar, and the sleep-wake cycle.
While important for immediate danger, cortisol can negatively impact the body if it remains elevated for a long period of time. When stress becomes long-term, your cortisol levels can stay high for longer than normal, potentially causing unwanted mental and physical symptoms that can affect your quality of life.
Cortisol levels naturally rise and fall throughout the day. Your body is effective at regulating the release of cortisol, but ongoing stress and certain lifestyle factors can keep it elevated for longer periods of time.
Some of the most common causes of high cortisol include:
Anything you can do to prevent stress or help your body manage it — from rest and exercise to nutrition and social support — can in turn support healthy cortisol levels over time. Not sure where to start? Consider the below lifestyle habits to promote a balanced stress response and reduce cortisol levels.
A predictable sleep pattern regulates your body’s circadian rhythm. Typically, your body releases cortisol in the morning to keep you alert, and then stops releasing it as you get closer to bedtime. Disrupted sleep can interfere with this pattern, causing cortisol to stay elevated when it’s time to go to bed. As a result, you might feel too wired for sleep, which means missing out on nervous system recovery time that helps your body stay resilient to stress.
Your nervous system needs nutrients to function properly, so a diet rich in fruits, vegetables, and other healthy foods is a great way to support healthy cortisol levels. Nutrition also plays a role in blood sugar regulation. If you skip meals or eat refined carbs or sugary foods, your blood sugar levels can temporarily dip in response. Your body then releases cortisol to bring your blood sugar back up. Eating a balanced, nourishing diet can keep your blood sugar levels stable and, in turn, keep cortisol more steady throughout the day.
Exercise, whether cardiovascular or strength training, is a controlled form of physical stress. When you do physical activity, your cortisol rises temporarily. Over time, though, exercise helps your body better regulate the stress response more effectively. This means you may be less likely to stay “elevated” after facing everyday challenges.
Sometimes, the body needs an external signal to “turn off” the stress response. Activities like deep breathing, mindfulness meditation, or guided imagery can send a message to your body that you’re safe, and it’s OK to relax — which can help shift you out of fight-or-flight more and lower your body’s cortisol levels in real time.
Caffeinated drinks and products can stimulate the secretion of cortisol. Too much caffeine, especially late in the day, can impair sleep (and cause stress on your body that increases cortisol). It can be tempting to rely on caffeine for alertness — especially if you’re already tired from high cortisol — but try to focus on healthier alternatives for energy, such as a nutritious diet, hydration, and exercise and time outdoors.
Spending time on hobbies or other activities you enjoy can help you manage stress, even when you can’t directly reduce it. Doing something you enjoy — whether cooking, reading, art, or volunteering in the community — infuses your day with moments of joy, connection, and purpose, which can help cultivate a more balanced stress response over time.
Spending time in natural environments like near parks, trees, or water has been shown to reduce cortisol levels, heart rate, and perceived stress, sometimes within minutes. The combination of fresh air, natural light, and lower sensory overload helps activate the parasympathetic (“rest and digest”) response.
Social connection and support can be a powerful regulator for cortisol, acting as a sort of “buffer” against stress. Connecting with a trusted individual — whether a friend, relative, or a therapist — can promote a sense of calmness while helping you process emotions that may be contributing to high stress levels. Even quick, simple moments of connection can help tell your body that you’re safe, allowing it to tamp down the stress response.
Nutritional supplements, such as vitamins, minerals, and herbs, may help support the nervous system or reduce the body’s reactivity to stress, rather than directly “lowering cortisol” in a targeted way. If you’re interested in learning what supplements help lower cortisol and adding one to your routine, talk to your medical provider to find out about the safest and most effective options for you.
Your body needs cortisol to function properly, especially under stress. Cortisol plays an important role in these physiological functions:
While cortisol helps your body function optimally when facing perceived danger, in the long-term, elevated cortisol can have unwanted effects on the body. Possible effects of high cortisol include fatigue, anxiety and depression, Cushing syndrome, digestive problems such as bloating or constipation, weight gain, sleep disturbances or insomnia, and high blood pressure.
Lifestyle changes can often help reduce the effects of stress and support healthy cortisol levels. But persistent stress, anxiety, sleep issues, or feelings of overwhelm that interfere with your daily functioning may indicate the need for additional support.
