Hubermanred light on the back lowered blood sugar 20–30%
When researchers shone red light on people's backs during a glucose tolerance test, it blunted their blood sugar by 20 to 30 percent — a result Huberman calls remarkable.Red light on the back blunted blood sugar by 20 to 30 percent — a result Huberman calls remarkable.

Key takeaways
- Huberman says long wavelength light goes into and through the body, not just onto it.
- He cites Glen Jeffery at University College London: who shone red light on the back during a glucose tolerance test and it blunted glucose by 20 to 30%, and he calls the result remarkable.
- His explanation: the light reaches mitochondria, which activate and use the body's energy to create more, so metabolism rises and blood sugar drops.
In their words
“Longwave light that bounces off greenery is tremendously good for our mitochondria. It actually can go into and through our body.”
“They shined a red light which approximates sunlight on people's backs while they did a glucose tolerance test. It blunts glucose levels somewhere between 20 and 30%. Which is remarkable.”
Context
Andrew Huberman, a Stanford neuroscientist and host of Huberman Lab, joined Megyn Kelly to discuss his book Protocols. About twenty-four minutes in, while explaining why daylight exposure matters, he described research at University College London in which red light approximating sunlight was shone on people's backs during a glucose tolerance test. He attributes the work to his colleague Glen Jeffery.
