Essentials: Timing Light for Better Sleep, Energy & Mood | Dr. Samer Hattar

Welcome to Huberman Lab Essentials, where we revisit past episodes for the most potent and actionable science-based tools for mental health, physical health, and performance. I'm Andrew Huberman and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. Today I have the pleasure of introducing Dr. Samur Hattar as my guest on the Huberman Lab podcast. And now my conversation with Dr.

Samur Hattar. Samur. Thanks for sitting down with me. My pleasure. You are best known in scientific circles for your work on how light impacts mood, learning, feeding, hunger, sleep, and these sorts of topics.

So maybe you could just wade us into what the relationship is between light and these things like mood and hunger, et cetera. Sure. So I mean you do appreciate the effect of light for vision. So when you wake up in a beautiful area, beautiful ocean, light is essential, the sunrise, the sunset. So that's your conscious perception of light.
