Jim Kwik explains that heat exposure activates brown fat, which supports metabolism. Aim for 57 minutes of sauna time per week, but keep individual sessions under 30 minutes. Even half that amount still delivers health benefits.
If you do these short-term protocols of cold and heat, you will have an activation of your brown fat. And it's only 57 minutes per week. And people might think, oh, that's a lot, but please don't do it at one time because that is way too much. You shouldn't do more than 30 minutes. That must be the higher threshold for that, if I can give that advice. If people are at the gym, then use the sauna because it's there anyways. You don't have to do 57 minutes a week. If you can do just half of that, that's also gonna give you some health. So do what you can.
