Cortisol, also known as the stress hormone, is produced by the adrenal glands. It helps our bodies deal with stressful situations and primes us for danger when our flight-or-fight mode is activated. While short-term cortisol release can be beneficial, high cortisol levels over an extended period can lead to health issues such as weight gain, insomnia, sleep apnea, and other chronic diseases. To improve sleep quality, it is essential to lower cortisol levels by managing stress through various means, including regular exercise, deep breathing, mindfulness practices, a healthy diet, and adequate sleep.

What You'll Learn
Reduce stress through mindfulness and deep breathing exercises
Cortisol is a stress hormone that is released by the adrenal glands. While short-term releases of cortisol can help your body deal with stressful situations, high levels of cortisol can cause various problems, including sleep issues such as insomnia, sleep apnea, and waking up during the night.
To lower cortisol levels, one effective method is to practice mindfulness. Mindfulness-based practices such as meditation can help you identify and manage stressful thoughts, leading to reduced stress and lower cortisol levels. For example, mindfulness-based stress reduction involves becoming more self-aware of stress-provoking thoughts and accepting them without judgment.
Deep breathing exercises are another powerful tool for stress relief. They can be easily incorporated into your daily routine and practiced anywhere. Here are some deep breathing techniques to help you reduce stress:
- Sit comfortably on the floor or in a chair. Breathe in through your nose to the count of five, then breathe out through your nose to the count of five. Repeat this cycle several times, gradually increasing the duration of your breaths.
- Tense and release different muscle groups as you breathe in and out. Start with your feet, then move up to your calves, legs, belly, chest, and so on. Imagine being a lion as you release the tension with a big, open mouth.
- Try box breathing by visualizing a box with four equal sides. Inhale slowly through your nose for a count of four, hold your breath for four, exhale through your mouth for four, and then hold your breath again for four before inhaling.
- Alternate nostril breathing, or Nadi Shodhana, is an ancient yogic technique. Breathe in through your right nostril, then close it off with your thumb. Exhale through your left nostril, and repeat as needed.
- Combine your deep breathing with a calming phrase or word. As you breathe in, say to yourself, "I breathe in peace and calm." As you breathe out, say, "I breathe out stress and tension."
By practicing mindfulness and deep breathing exercises, you can effectively reduce stress and lower your cortisol levels, promoting better sleep.

Avoid caffeine and consume a healthy, whole-food diet
Caffeine is known to interfere with a good night's sleep, so it is best to avoid consuming caffeine in the evening. Caffeine can also raise cortisol levels and contribute to a vicious cycle of exhaustion and caffeine dependence.
A healthy, whole-food diet is critical for lowering cortisol levels and improving sleep. Eating a balanced diet with a variety of fruits and vegetables is an excellent way to ensure you are getting enough fiber, which helps regulate gut bacteria and hormones, including cortisol. An unhealthy diet filled with added sugars and processed foods can increase cortisol levels and lead to various health risks, such as high blood pressure, obesity, and diabetes.
It is also important to prioritize good nutrition by incorporating anti-inflammatory foods into your diet, which may help calm your body and slow the production of cortisol. Magnesium-rich foods, such as avocados, bananas, dark chocolate, broccoli, and spinach, are particularly beneficial for regulating cortisol levels.
Additionally, staying hydrated is an important aspect of a healthy diet. Water has been shown to have natural stress-relieving properties, which can help reduce cortisol levels.
In summary, avoiding caffeine, especially in the evening, and adopting a healthy, whole-food diet with a focus on fiber, anti-inflammatory foods, and adequate hydration are essential strategies for lowering cortisol levels and improving sleep quality.

Exercise regularly, but avoid intense exercise late at night
Exercise is a great way to lower cortisol levels and improve your sleep. It can help you manage stress and promote good health, which may help lower cortisol levels. Aim for around 150–200 minutes of mostly low- to moderate-intensity exercise each week, such as walking, swimming, or cycling. Regular exercise may lead to greater resilience to acute stress and may lower the adverse health effects associated with high cortisol levels.
However, it is important to avoid intense exercise late at night. Exercising late in the day can increase cortisol levels and make it difficult to fall asleep. Cortisol is a stress hormone that helps your body deal with stressful situations, and its release is triggered by the brain through the sympathetic nervous system, or the \"fight or flight\" system. While short-term cortisol release can help you deal with danger, high cortisol levels for prolonged periods can lead to health issues like weight gain and chronic diseases.
In addition to regular exercise, there are other lifestyle changes that can help lower cortisol levels and improve sleep. These include reducing stress through mindfulness practices, deep breathing, and meditation. Creating a relaxing bedtime routine and improving your diet by including more nutrient-dense and magnesium-rich foods can also help.
It is important to maintain regular sleep patterns and get enough sleep each night. Sleep deprivation can lead to increased cortisol levels, creating a vicious cycle where elevated cortisol disrupts sleep, and lack of sleep raises cortisol levels.
By exercising regularly, avoiding intense late-night workouts, and incorporating other healthy habits, you can effectively lower your cortisol levels and improve your sleep quality.

Get enough sleep and maintain a regular sleep-wake schedule
Getting enough sleep is crucial for maintaining healthy cortisol levels. Sleep loss and high cortisol create a vicious cycle: elevated cortisol can disrupt sleep, and lack of sleep raises cortisol levels. This can increase the risk of sleep disorders like insomnia and sleep apnea.
To break this cycle, aim for seven to eight hours of sleep per night. This allows the body to heal and can help regulate cortisol levels. Maintaining a regular sleep-wake schedule is essential, as it helps to keep cortisol levels in check. Try to go to bed and wake up at the same time each day, even on weekends. This reinforces your body's natural sleep-wake cycle and promotes healthy cortisol regulation.
Creating a relaxing bedtime routine is a great way to improve your sleep hygiene and lower cortisol levels. Start by turning off all screens at least an hour before bed. The blue light emitted by electronic devices can interfere with your sleep and keep cortisol levels elevated. Instead, engage in relaxing activities that help you unwind, such as reading, listening to soothing music, or practising deep breathing exercises.
Additionally, be mindful of your caffeine intake, especially in the evening. Caffeine can disrupt your sleep and raise cortisol levels. Avoid consuming caffeine after 2–3 p.m. and opt for caffeine-free alternatives in the evening. This will help you fall asleep more easily and improve your overall sleep quality.
Finally, pay attention to your diet. A nutrient-dense diet can help lower cortisol levels and improve your sleep. Include plenty of fruits, vegetables, and magnesium-rich foods like avocados, bananas, dark chocolate, broccoli, and spinach. These foods provide essential nutrients and help regulate hormones, including cortisol.

Try supplements like fish oil, magnesium, or ashwagandha
If you're looking to lower your cortisol levels for better sleep, you may want to consider trying certain supplements. High levels of cortisol, the stress hormone, can cause various health problems, including weight gain and chronic diseases. While regular exercise, adequate sleep, and a nutrient-dense diet can help lower cortisol levels, supplements like fish oil, magnesium, and ashwagandha may also be beneficial.
Fish oil, or omega-3 fatty acids, have been shown to help lower cortisol levels and reduce inflammation during stressful events. A study found that participants who took a combined supplementation of fish oil (60 mg per day) and DHA (252 mg/day) experienced significantly lower cortisol levels when performing a stressful task compared to those given a placebo. Additionally, a longitudinal study with 2,724 participants linked higher omega-3 levels in the blood with reduced inflammation and cortisol levels.
Magnesium is another supplement that has been found to help manage cortisol levels. It is an essential element that our bodies need for various biological processes, including cell functioning and energy utilization. While more research is needed, some studies suggest that magnesium can help reduce anxiety and stress levels by blocking the neuroendocrine pathways that send cortisol to the brain.
Ashwagandha is an adaptogenic herb that has been used in Ayurvedic medicine for centuries to help the body adapt to stress and promote relaxation. While there is limited research on its direct effect on cortisol levels, ashwagandha has been found to reduce stress and anxiety, which may indirectly contribute to lowering cortisol.
It is important to consult with a healthcare professional before taking any new supplements to ensure they are safe and appropriate for your individual needs. Additionally, combining supplements with other lifestyle changes, such as regular exercise, a healthy diet, and mindfulness practices, can further contribute to lowering cortisol levels and improving sleep quality.
