My guest today is Neuroscientist Andrew Huberman. Andrew is a Professor of Neurobiology and Ophthalmology at Stanford. Andrew runs Stanford's lab that primarily studies brain states - such as fear, courage, anxiety, calm - and how we can better move into and out of them through practices like visual cues, breathwork, movement, and supplementation. We just had Andrew on for episode 1204 where we talked about having the perfect morning routine, eliminating brain fog and managing your dopamine levels.. so make sure to go to lewishowes.com/1204 so you can check that out if you missed it. In this episode we discuss how sleeping poorly negatively affects you, the main things that prevent you from sleeping well and how to fix them, how nutrition and exercise affect sleep, what is happening in the brain when we sleep and so much more!
