Sauna offers many positive effects on health

15.05.2018

Anyone who has been to sauna can testify for its relaxing effect, but the health benefits of sauna bathing have also been studied scientifically since the 18th century. The latest studies have shown that the most notable changes while having a sauna occur in the blood circulation. In room temperature, approximately 10% of the blood pumped by the heart goes to the skin. When skin warms up, the capillaries expand and the veins in the skin grow in capacity. While in the sauna, up to 70% of the blood pumped by the heart can go to the skin, practically making the blood circulate through the skin.

 

During sauna bathing, heart rate rises to the level corresponding to medium hard exercise and tests1 taken right after sauna show, that the elasticity of veins improves, carrying effect on both blood pressure as well as the functioning of the heart. A study1 shows that as a result of enjoying a sauna, the average systolic blood pressure lowers from the level of 137 to 130 and the diastolic pressure from the level of 82 to 75. The systolic pressure stayed lower even half an hour after the sauna. The expanding surface blood vessels are seen as redness on the skin.

 

An international study2 proves that abundant sauna bathing is connected to a decreased risk of stroke. The study shows that people who bathe in sauna 4-7 times a week have a 61% smaller chance of suffering a stroke than those who only go to sauna once a week. Sauna bathing 2-3 times a week lowers the risk by 14%. According to the scientists, the connection might be attributed to the lowering of the blood pressure, the activating of the immune system and the autonomous nervous system as well as the improved functioning of the cardiovascular system brought on by sauna bathing.

Sauna also alleviates breathing of asthmatics by expanding the bronchi.

Venture through the hole in the ice!

People who are into winter swimming can’t stop talking about the euphoric feeling after dipping into a hole in the ice, but there are also scientific facts about this. These are the benefits on ice swimming:

  • release of endorphins
  • release of cortisol, which reduces ia. joint pains
  • may increase the amount of antioxidants in the body
  • you’ll feel refreshed
  • you’ll sleep better
  • activates brown fat, which then stimulates metabolism
  • may restrain skin from drying
  • you’ll get a sense of having courage

Ice swimming should be avoided if you have a heart condition, suffer from cold urticaria hives or if you’re hungover.

Can sauna bathing be harmful?

Sitting in a steaming hot sauna might sound a bit frightening to a first-timer. However there are no observations in the studies of any health risks for healthy people. There are some things to take into consideration though.

Heart conditions and ice swimming

Going for a dip in a frozen lake straight from the sauna makes the superficial blood vessels to contract and the blood pressure to rise quickly and quite significantly. For a healthy person this big a rise of the blood pressure is not generally harmful, but if you suffer from a heart failure, the increased blood pressure could be dangerous.

Sauna bathe only when sober

Sauna is not recommended for anyone under the influence. The risks of sauna bathing intoxicated include ia. slipping, not recognizing your limits, irregular heartbeat and falling asleep in the sauna, which might lead to dehydration.
