Why does using a sauna improve sleep quality?

Editor’s note
This article was inspired by the question my sauna buddy asked our instructor during a recent contrast therapy session. He was curious why he slept so well following a sauna, and I was just as curious.
I was already aware of the chemical changes, such as reduced cortisol levels and the release of endorphins and melatonin, but what I found especially interesting was how improved oxygen and circulation also contribute to a good night’s sleep.
Over the years, I’ve realized that optimizing my sleep is one of the best ways to show up as my best version of myself while I’m awake. Who knew that something as simple as melting in a sauna could be such a powerful tool for better rest?
Cheers to your health and great sleep, tonight and always!

Saunas have long been celebrated for their ability to promote relaxation and overall well-being. However, sauna benefits extend far beyond just providing a tranquil escape from the stresses of daily life. Emerging research has shed light on the positive impact saunas can have on sleep quality, making them a valuable addition to any wellness routine.
From reducing stress and promoting muscle relaxation to regulating hormones and improving respiratory function, saunas offer a holistic approach to achieving better sleep. By understanding the connection between heat therapy and sleep quality, you can unlock the transformative power of saunas and their potential to revolutionize your sleep experience.
Physical Relaxation
Muscle Relaxation
In today’s fast-paced world, finding effective ways to unwind is crucial for maintaining good sleep quality. Saunas have long been recognized for their ability to promote relaxation and reduce stress. The heat from a sauna helps to relax muscles, easing tension and promoting a sense of calm. This relaxation is essential for preparing the body for restful sleep, as it allows the mind to let go of daily stressors.
Pain Relief
Additional physical benefits of sauna sessions can also indirectly contribute to improved sleep quality. One such benefit is pain relief. Many people suffering from joint stiffness or arthritis find that the heat from sauna alleviates discomfort. This relief helps create a more conducive environment for restful sleep.
Chemical Changes
Stress Reduction
One of the key benefits of sauna use is its impact on cortisol levels. Cortisol, often referred to as the stress hormone, can interfere with sleep when elevated. Regular sauna sessions have been shown to decrease cortisol levels, creating an environment conducive to better sleep. By incorporating sauna relaxation benefits into your routine, you can enhance your overall sleep quality.
Mood Enhancement
Sauna use triggers the release of endorphins, the body’s natural feel-good chemicals. This endorphin release not only improves mood but also contributes to a more relaxed state, making it easier to fall asleep. The positive effects of endorphins on mood and relaxation are well-documented, making sauna therapy an effective sleep improvement technique.
Melatonin Regulation
Melatonin, the hormone responsible for regulating sleep-wake cycles, is influenced by sauna use. The heat exposure helps to regulate melatonin production, aligning it with the body’s natural circadian rhythm. Additionally, the gradual cooling of the body post-sauna session mimics the natural drop in body temperature that occurs before sleep, further promoting restful sleep.
Respiratory and Cardiovascular Benefits
Improved Circulation and Oxygen
Thanks to the increased heart rate that accompanies a sauna session, blood vessels dilate, enhancing circulation, increasing blood flow and oxygen supply throughout the body. This improved circulation supports overall cardiovascular health and ensures that tissues receive an adequate supply of oxygen. By ensuring that the body receives adequate oxygen, regular sauna use helps prevent sleep disturbances and promote uninterrupted rest.
Enhanced Respiratory Function
Regular sauna use can also improve respiratory function, which is crucial for maintaining good sleep quality. The heat and steam from a wet sauna can help clear airways and improve breathing, reducing the likelihood of sleep disruptions. For those seeking a natural way to enhance their sleep, incorporating sauna therapy strengthens the body’s adaptive responses and improves overall cardiometabolic health.
Sauna Best Practices
For safe and effective sauna use, consider the following best practices:
- Schedule your sauna session 1-2 hours before bedtime to allow your body temperature to gradually cool down, mimicking the natural temperature drop that promotes sleep onset.
- Limit your sauna exposure to 15-20 minutes.
- Drink water before, during, and after your sauna session to prevent dehydration.
- Avoid consuming alcohol or caffeine before or after your sauna session.
- Consult with a healthcare professional if you have any underlying medical conditions or concerns before incorporating sauna use into your routine.
