Bryan Johnson runs 200°F sauna sessions five times a week with an elaborate cooling setup: a silicone mask, ice packs on his face and genitals, a sauna hat, and neck ice to manage extreme heat. He emphasizes this is experimental and unnecessary for most people, designed to protect thin-skinned areas and preserve his devices.
I've done over 250 sessions of sauna, and this is what I wear every day. First is this medical-grade silicone mask. This is a base layer between the ice and my face. We're doing an experiment to see if icing the face, keeping it cool, protects thin-skinned areas like the face and the neck. This layer goes on first. Next up, the ice I put on my face. This will cool my face to about 50 degrees Fahrenheit. You can see this is plastic, which is another benefit of this medical-grade silicone. It protects the layer between my skin and the plastic. Next up is a sauna hat. I use this to minimize damage on for the scalp and hair. Next, we have these BPA-free, toxin-free ice packs. These will go on the boys. Once I'm inside, I just have cotton shorts and cotton underwear. I'll put them in between. Not just one, not just two, but three. One for each boy. Next up is cooling for the neck. This is another thin-skinned area that is at risk with high thermal temperature. Pro tip, ice on the neck also tricks the body into feeling cooler, which can make the sauna more manageable. Next up, I put ice on my CGM. This is looking at my blood glucose. If I don't ice it, it will die. That'll keep it cool. 2 final things. A mitt, which I use for my left hand. I keep my left hand outside the towel, and so this provides protection. And then I have one large cotton towel I drape over me, and then 2 small cotton towels, and I swipe the sweat off my body. Out of everything in my sauna protocol, I would say the essentials are a dry sauna, cotton shorts, cotton towel, a sauna hat, and men, ice on the boys. Now friends, to be clear, this is ridiculous. You do not need to do this. I sauna at extreme temperatures at least 5 times per week. Now I'm gonna hop in, 200 degrees Fahrenheit for 20 minutes.
