Bryan Johnson and Kate swallow a pill that tracks core body temperature while sitting in a 200°F sauna. Bryan claims 102.2°F unlocks sauna's full health benefits. Kate pushes through nausea to hit the target after 33 minutes, despite Bryan urging her to stop.
This pill tracks your core body temperature every 15 seconds.
And we're both taking one to see how our bodies react to a 200-degree sauna.
I'm pretty nervous because Bryan does this all the time. My body temperature is 97.7 degrees Fahrenheit.
And mine's 99.6 degrees Fahrenheit.
Our goal is to get to 102.2 degrees Fahrenheit.
I've never been in the sauna for as long as it needs to, to be able to hit this core body temperature.
Sauna has a lot of health benefits, but people don't realize it's Core temperature dependent. If you get into a sauna and you don't hit a certain threshold, you get fewer benefits. The higher the core body temperature gets, the more benefits you unlock.
101.39 for you, Kate. Bryan, you're at 100.4. I think I should— Stop?
Yeah, this is like— we want the experiment, but we don't want this to be dangerous.
Yeah, I'm feeling nauseated.
Yeah, I think we should call it. We don't— it's gonna be dangerous.
No, I wanna do it.
Let's go.
No.
Kate.
No.
Let's go up to 37.
No, I'm staying in. Close the door. Just keep an eye on my temperature. All right, it's not sis. I know. Got it.
Oh my God, are you okay? Is your head— you're still climbing. I was telling her repeatedly to get out. I didn't want you to get hurt.
I literally did it only for women. I don't give a fuck about my internal temperature, but I know that the girls are so happy to have someone who's doing this for them. For the women! It took 33 minutes for my internal body temperature hit the target amount. I honestly didn't know if I was gonna make it. I know women at home are watching me for this role, and I wanna show up for you guys. And so I'm really, really happy that we did it.
I'm so proud of Kate. That is just insanely hard. Good job.
Thanks.
