Tomorrow morning, when you take a shower, take a nice warm shower. At the end of the shower with the water hitting you right in the forehead and chest, turn it to full cold. Sounds like great advice. That's so much fun. Can't wait to do it in the morning. After eight seconds, you're going to be like, dave Asprey's a jerk. But if you stick with me for four days, the next day you'll do it. You'll last, like, 20 seconds. And what's going to happen is the voice in your head, which is your mitochondria, is going to say, you're going to die. You must get out. It's unbearable to be in here. But you rationally know if I'm in here for one minute, I'm not going to die. But it feels like it. And you believe that feeling. But what you're doing is you're telling the mitochondria here, if you can't make enough energy to keep yourself warm for just a minute of cold water, then you're weak and you should die. And that's them saying, please don't kill me. Please don't kill me. After the fourth day, you're like, you know what? This isn't that cold. In fact, I feel invigorated. My skin is tighter. I'm losing weight. I feel good. I sleep better. Like, it's really powerful. And we're talking one minute of cold water, four days of pain first. And then all of a sudden, just believe me, just try it for a week. You're like, you know what? I like my life when I do this. You like the Iceman.
