When your body is exposed to the heat in a sauna, your blood vessels widen—a process called vasodilation—which leads to enhanced blood flow, increased heart rate, and the promotion of better circulation.

The heat in saunas has been found to trigger the release of endorphins (the body’s natural mood boosters) as well as lower cortisol levels (the body’s natural stress hormone), alleviating overall stress and anxiety. Taking the time for a sauna session, especially if done socially with friends, can help reduce stress and promote relaxation.

Saunas are particularly well known for their ability to alleviate muscle and joint pain. The increased circulation caused by heat in the sauna can aid in muscle recovery and growth and reduce inflammation.

Studies have found that saunas may help reduce symptoms of chronic conditions like rheumatoid arthritis, fibromyalgia, and ankylosing spondylitis. While heat therapy should be one part of a more comprehensive treatment for conditions of this nature, the benefits and relaxation provided by sauna use can help relieve pain and reduce discomfort.

The heat in saunas naturally encourages sweating, which helps cleanse the skin by unclogging and removing impurities from your pores. Plus, the increase in blood circulation caused by sauna use also contributes to a healthy, radiant glow.

Sweating profusely in a sauna can remove toxins and heavy metals from the body in a process called thermal detoxification. You’ll notice that sweat plays a role in a lot of these benefits, as sweating can help remove harmful substances from your body and support your overall health.

The soothing heat of a sauna can help relieve stress and tension, among other benefits, making it easier to fall asleep and enjoy a more restful night.

The increased heart rate and circulation generated during sauna sessions can lead to increased energy expenditure, temporarily boosting your metabolism. This may also aid in weight management and calorie burning to some extent.
