Bryan Johnson measures his inner-ear temperature each morning with a Braun scanner, typically reading 95-96°F, about three degrees lower than average. He attributes the difference to his diet and uses the reading as a safety check for his therapies. He then sits under a 10,000 LU UV light positioned 12 inches away to simulate morning sunlight.
The first thing I'm going to do is use this Braun thermal scan device. I measure my inner ear temperature every day. I do this as a safety and efficacy check for various therapies we're doing. If I'm running hot, then we know it's an indicator of something. 96 this morning. So my body runs around 3 degrees Fahrenheit, roughly cooler than normal. Most people are 98.7, thereabouts. I run around 95, 5, or 96. It's a result of my dietary protocol. After this, I'll flip on this UV light. This is 10,000 LU at 12 inches. I turn this on, and I usually just enjoy thinking about the day for a minute. I just get a few minutes of exposure. I wake up normally when it's dark outside, and so I can't see the sun. And so in place of the sun, I'll use this device.
