Key takeaways
- Huberman says sunlight is full spectrum — UV, short, medium and long wavelength — and that the balance is the key.
- He says you need some UV for vitamin D and mood, but too much damages skin and accelerates aging.
- He points to work on long wavelength light and recovery from surgery and illness, respiratory infections, skin, eye health and longevity.
- His low-cost options: a red light LED device or a red incandescent bulb.
In their words
“The long wavelength light turns out to be the key. Sunlight is full spectrum.”
“Recovery from surgery, recovery from illness, staving off illness… skin health, eye health, longevity is get that long wavelength light.”
Context
Andrew Huberman, a Stanford neuroscientist and host of Huberman Lab, joined Megyn Kelly to discuss his book Protocols. About an hour and eighteen minutes in, he broke sunlight into its parts — UV, short, medium and long wavelength — and argued that the long-wavelength end is the part that does the work, while UV is the part to limit. He returns to the same point a couple of minutes later with a list of what the research has looked at.
