Bryan Johnson's team tested a theta-wave audio track from YouTube for sleep. He played it at 5:30 pm and felt so drowsy he had to lie down. For ten days straight, his sleep quality improved and his heart-rate variability went up.
With blueprint, we probably trial five to 10 new things in any given week. It's the identification of the thing, the evidence that supports it, whether it's strong or emergent. One thing we've been trialing lately, which was kind of funny, was using theta waves for improved sleep at hrv. And so I'll play this for you. It's just something you can find on YouTube. This is what it sounds like. Can you get that? Okay. The first time that I. I listened to this, we found some evidence this might be interesting. And so I turned it on. It was like 5:30 in the evening. I turned on the speaker so it was broadcasting. There were a few of us here hanging out. I didn't think anything of it. And I was on the couch talking to my mom. I got so tired. I just became paralyzed. Like I needed to lay down. I was like, mom, I'm so sorry. I need to stop this conversation right now because I need to lay down. It just had this immediate and dramatic effect on how tired I was. And it increased my sleep quality and my HRV for 10 solid days.
