dry sauna vs wet sauna

Dry and wet saunas, while both beneficial, have different setups and effects. According to Andrew Huberman, the choice between a wet or dry sauna is a matter of personal preference, as both can provide similar health benefits if the temperatures are adequately high. He emphasizes that temperatures in a sauna should range between 80 to 100 degrees Celsius for optimal effect.

For heat exposure, shorter sessions multiple times a week are most beneficial. The optimal frequency for sauna use is 2-3 times per week, increasing benefits such as decreasing the likelihood of cardiovascular events by 27%, compared to just once a week. Even more frequent use (4-7 times a week) can lead to a 50% reduction in the likelihood of cardiovascular incidents. These sessions help improve body's ability to sweat and regulate heat, which is crucial for dumping excess heat through sweating 1 2.

Regardless of the type, consistency and adherence to safety guidelines, including adequate hydration and not overheating, are crucial (3). Infrared saunas, often considered a type of wet sauna, typically don’t reach the higher temperatures seen in traditional dry saunas but can still offer benefits, especially when sessions are prolonged to compensate for the lower temperatures 4.

Overall, whether you choose a dry or wet sauna, the focus should be on achieving sufficient temperature exposure and hydration to maximize health benefits and safety.
