The International Agency for Research on Cancer has now classified overnight shift work as a Group 2A carcinogen. This means that staying up late repeatedly, and working overnight, is a strong enough cancer-causing agent to be lumped in with lead exposure and UVA radiation. That might sound crazy, but there s now a ton of scientific data showing exactly how this happens.

Shift work that involves circadian disruption? Carcinogen.

A while back I wrote a piece on Sleep. It turned into three parts and after writing it, I felt I had only scratched the surface. Then I stumbled over this book.

I read the book and it’s really good! I blasted through it agreeing all the way. If you know everything about sleep, you’ll still enjoy seeing it all laid out in an approachable fashion. If you have NOT YET MASTERED SLEEP — wait, what is wrong with you?! Sleep is the single most important thing in your life. It is the activity you spend the most aggregated time doing. Remind me why you have not spent time studying sleep and improving yours?
