How long should you stay in a sauna?
A Good Rule of Thumb: For new sauna users, spending 10-15 minutes per round with cool-downs in between (important) is recommended.
Your first round might be longer, especially if you start with a cold body temperature. That first sweat can take 10-15 minutes.
Consider 2-3 rounds with cold plunges in between to maximize health benefits.
Important Factors When Considering How Long To Stay In a Sauna
Nature doesn't hurry and it's always on time. While enjoying a sauna, always listen to your body and don't push yourself too hard.
It's wise to have a sauna buddy, limit alcohol, drink plenty of water, and exit when your body signals you to do so.
Factors such as age, health conditions, previous sauna experience, and pregnancy should also be considered.
And you can always adjust the temperature if you want to spend more time in sauna bliss. Learn more about sauna temperature here.
Most modern saunas have a big problem with heat settling at the top and staying cool at the bottom. More traditional Finnish saunas had huge stoves and leaky floors so air was always moving through the hot room and keeping more level temperature.
There's a good chance your head is at 180 degrees and your feet will still be cool in a modern sauna. This does not allow you to stay in the sauna long enough to get the benefits to your entire body.
That why sauna hats have become so popular. It helps your head stay protected from the hottest heat while the rest of the body catches up.
The real solution is better air ventilation, higher benches, or a Saunum air system that's designed to bring air from the top of the sauna to the bottom. Saunum Air and Saunum Air Solo are now available in the USA and Canada.
Cool Down Between Sessions
An authentic Finnish sauna session has a method to cool down between sessions. Ideally, in a lake or stream, but cold showers are popular in Finland. Cold plunges have become a popular way to get the benefits of cold exposure in America.
