Sauna for immune system

Using a sauna can have several benefits for the immune system. Andrew Huberman discusses how sauna sessions can enhance the activity of the innate immune system by increasing levels of white blood cells and cortisol in ways beneficial for combating infection 1 2.

A recent study explored the effects of sauna use on immune response, showing that regular sauna sessions led to significant increases in leukocyte levels, which are a part of the innate immune system. This suggests that sauna use can help prevent and mitigate colds and flu by boosting immune function 2. The procedure generally involves three rounds of 15 minutes in the sauna, with cool-down periods in between, which can be further enhanced by cold showers or cool air exposure 3 4.

However, it's important to use saunas wisely. Safety should be prioritized, and those feeling particularly unwell should avoid intense heat exposure since it can add unnecessary stress to the body 2. Regular sauna use, when done safely, can be an effective practice to support immune health and general well-being.
