What are the different types of saunas?

Andrew Huberman discusses various types of saunas and their benefits on his podcast. Here are the different types of saunas mentioned:

1. Dry Sauna: Traditional saunas that use heated rocks or other elements to warm the air inside the sauna.
2. Steam Sauna: These saunas use steam to heat the environment, providing a different kind of heat exposure characterized by high humidity.
3. Infrared Sauna: These saunas use infrared light to warm the body directly without significantly heating the air around you. Infrared saunas typically operate at a lower temperature compared to traditional saunas 1 2.

Each type has its own mechanism for heating and potential health benefits, but the fundamental principle is the exposure to heat which can be beneficial for cardiovascular health and mental well-being 3 4.
