I’m still on my sleep kick. And, given that I’m currently at the Z-Health 9S: Sustenance & Spirit course, I think an article about BMI is fitting.
In another (somewhat) recent article from Science Daily, a study of ~1,800 twins, they found that individuals who sleep 7-8.9 hours/night have a lower BMI than those who sleep either more or less. They controlled for genetics and shared environment.
I believe that while sleep has many restorative properties on its own, but that that quantity of sleep also generally speaks to someone’s overall lifestyle. Way less sleep means you are probably burning the candle at both ends, suffer from high cortisol levels, and generally have too much going on so are not paying proper attention to diet and exercise. Considerably more sleep oftentimes reflects a considerably less active lifestyle (for any of a number of reasons).
