Matthew Walker's Why We Sleep, and Satchin Panda's Circadian Code that are pretty breezy reads. (there are YouTube interviews and TED talks as well): For those that prefer more succinct reviews and want to spelunk citations, these are a couple good starting points:…

The squat raises the energy from the sole of the foot and the pushup conducts it through out the body. 4) Read Dr. Satchin Panda's book "The Circadian Code" (and watch his videos on Youtube; eg. https://www.youtube.com/watch?v=fciGNBN0nKM) and setup your daily activities in accordance with your circadian rhythm.

Of relevance here is also the book The Circadian Code by Dr. Satchin Panda.

on “A walk in nature restores attention” ↗One of the study authors is Dr. Satchin Panda, from the Salk Institute. (He appears to be a real working scientist, unlike most health influencers.) I learned a lot from his book The Circadian Code.

However, it doesn't contain a lot of practical advice (other than the 12 points at the end of the book, which were released already by National Sleep Association) Somewhat tangetial, check out "The Circadian Code" as well - a lot of more practical advice in this one.

on “Melatonin: Much More Than You Wanted to Know” ↗I've had my share of sleep problems in the past.
