What’s happening with people in hot tub?
In the 1990s, Japan had a rising trend of having big bath houses called “super sento”. Hot tubs are popular.
In Finland, the people have a tradition of using a cycle of hot tub, followed by a cold bath and going outdoors for a breath of fresh cold air. Then, this cycle is repeated again. The continuous alternation of hot and cold encourages the body to release norepinephrine and endorphins. This makes the body feel good. This optimum state is called totonou, where happiness and clarity can be obtained.
Every individual has their own optimum saturation to attain totonou. A person may require three or more cycles of hot bath, cold bath and cold air to reach totonou.
