How Saunas Work?

Heat Exposure and Body Response

 

When you take a stress relief sauna session, your body gets heated up causing heart rate and the blood vessels are dilating. This boosts blood circulation in the body, like mild exercise. Sweating aids in eliminating toxins, inflammation and aids in immune system boost.

  • Increased Heart Rate: Your heart beats a great deal more rapidly (it can often be mimicking moderate exercise) to pump more blood.
  • Vasodilation: Blood vessels located close to the skin widen to get the blood closer to the skin surface, which helps to cool down. This is essential in the way saunas boost blood circulation.
  • Sweating: Sweat glands function at a vigorous rate and produce sweat, which cools the skin through its vaporisation, the most prominent and well-known effect of sauna usage.
  • Relaxed Response: The heat relaxes muscles and tension levels, reduces cortisol levels as if by magic creating that well-known stress relief sauna effect.
  • Activation of Immunity: The heating effect of heat stress triggers the immune cells which can assist in supplementing an immune system boost.

Simply put, sauna heat places your body in a kind of gentle exercise state which results in better blood flow, relaxation, toxification, and recovery.
