In the high temperatures of a sauna, skin heats up and core body temperature rises. In response to these increased heat levels, the blood vessels near the skin dilate and “cardiac output/circulation” increases. Medical research has told us that the heart rate can rise from 60-70 bpm (beats per minute) to 110-120 bpm in the sauna (140-150 bpm with more intensive bathing), and can often sink to below normal after the cooling off stage. Regular sauna usage has been shown to reduce the risk of all-cause mortality and fatal cardiac incidents along with reduced risk of stroke and hypertension.

Saunas are simply treated as one of many tools in our arsenal when it comes to burning additional calories. The sweating process itself requires a notable amount of energy. That energy is derived from the conversion of fat and carbohydrates in a bodily process that burns up calories. A moderately conditioned person can easily sweat off 500 grams in a sauna in a single session, consuming nearly 300 calories in the process. The body consumes said calories due to the acceleration of heart activity.

Due to the heat of a sauna, the core body temperature begins to rise. Sweat production is primarily designed to cool the body, and is composed of 99% water. However, deep sweating in a sauna can help reduce levels of lead, copper, zinc, nickel, mercury and chemicals - which are all toxins commonly absorbed just from interacting with our daily environments. Heat bathing is one of the oldest beauty and/or health strategies in terms of cleansing one’s skin. When the body begins to produce sweat via deep sweating, the skin is then cleansed and dead skin cells are replaced - keeping your skin in good working condition. Sweating rinses bacteria out of the epidermal layer and sweat ducts. Cleansing of the pores has been shown to improve the capillary circulation, while giving the skin a softer-looking quality.

Research has shown that a deeper, more relaxed sleep can result from sauna use. In addition to the release of endorphins, body temperatures that be come elevated in the late evening, fall at bedtime. This slow, relaxing decline in endorphins is key in facilitating sleep. Sauna bathers worldwide enjoy the deep sleep experiences resulting from the calming heat of an evening sauna.

Saunas relax muscles and soothe aches/pains in both muscles and joints. Under the high-heat provided by a sauna, the body releases endorphins which can minimize pain and is often associated with a “runner’s high.” As the body temperature rises in the heat of the sauna, blood vessels dilate allowing for increased blood circulation, which in turn speeds the body’s natural healing process. After physical activity, use the heat and steam of a sauna to promote muscle relaxation by helping to reduce muscle tension and eliminate lactic acid and other toxins that may be present.
