Walk into our Finnish sauna at MindFuel and you will see members in wool caps. New visitors usually ask about them. There is a real reason, and most people who use traditional saunas have no idea.
If you sauna regularly in Pittsburgh, this matters. Two things you should be doing in a hot traditional sauna that almost nobody talks about, and a wool cap solves both of them.
What Is a Sauna Hat?
A sauna hat is a wool or felt cap that covers your head and ears in a traditional sauna. They come from Finnish and Russian banya culture and have been part of the high-heat sauna ritual for hundreds of years. There is a reason men and women in Russian banyas wear them.
This applies to traditional Finnish sauna, the kind we run at MindFuel. Wet or dry. Hot. Typically between 174 and 212 degrees Fahrenheit. It does not apply to infrared saunas, which work on a different mechanism and run cooler.
Two Real Reasons to Cover Your Head
Dr. Andrew Huberman, neuroscientist and host of the Huberman Lab podcast, recently broke this down in a post worth watching. He gives two reasons.
1. Protect Your Hair
Heat denatures proteins. Your hair is protein. Sit in a 200 degree sauna multiple times a week and your hair gets brittle. It is not permanent. Hair grows out. But it is noticeable, and most regular sauna users have felt it. A wool cap or even a folded towel over your head fixes it.
2. Protect Your Brain (and Stay In Longer)
This is the one almost nobody talks about.
Inside your hypothalamus is a small cluster of neurons called the medial preoptic area. It sits roughly above the roof of your mouth. One of its jobs is monitoring your core body temperature. When that temperature climbs too far, the brain fires the impulse to leave the heat, fast. That is the moment a great session turns into "I have to get out."
Insulating your head with a wool cap slows the rate at which that part of your brain heats up. The result: you can stay in longer, more comfortably, without forcing it.
Will I Lose the Sauna Benefits?
No. Covering your head does not blunt the cardiovascular benefits, growth hormone release, heat shock response, or longevity benefits of traditional sauna. Those benefits come from your core body temperature rising and your heart working harder, not from how hot the top of your head gets.
You are protecting your hair and your brain. The benefits keep stacking.
What About Infrared or Red Light Saunas?
Different mechanism. Red light comes from above, the chambers run cooler (typically under 170 degrees), and the red and near-infrared wavelengths actually have benefits for the scalp and mitochondrial health. In a red light or infrared sauna, you do not need to cover your head. Our red light therapy bed in the Recovery Lounge is a good example. Keep your head exposed.
How to Use a Sauna Hat
- Soak it briefly in cool water before going in. Cold water in the cap, not hot.
- Pull it down to cover your ears.
- Hydrate. Water and electrolytes during or after, especially if you are stacking rounds with cold plunge.
- Build up. Do not jump straight to long sessions just because you have a cap.
Huberman's own protocol is three rounds of 20 minutes at 210+ degrees, with three minutes of cold plunge between rounds. He notes he is heat adapted. Most people work up to that.
A Few Precautions
This applies to high-heat sauna in general, not just sauna hats. Pregnant women should avoid prolonged high-heat exposure. Men trying to conceive in the next 90 days should know that high heat can affect sperm. If you have a heart condition or any chronic medical issue, check with your doctor before starting a regular sauna routine.
