Of all the health habits I've been working on good sleep targets, which you'd think would be the easist, have been the trickiest for me to get right. At least not in consistant ways, long term. And I know it is as important or more than eating well, getting right level of steps and workouts in. Maybe more as it impacts those other habits. And there is this:

"New research, published in the journal Nature on May 13, does suggest that there’s a sleep “sweet spot” between 6.4 and… 🧵 1/3
…7.8 hours of sleep a night. People who hit that amount had better functioning of the immune system, brain and heart, as well as other organs, when measured on the molecular level."

Still, work, life, stress, etc, plays a real number on me on this one. 🧵 2/3
@tchambers Good sleeper here, close to 8 hours a night; fast walking 5 km a day, excellent Mediterranean-Japanese diet. Reached 83 with no hospitalizations or broken bones, etc. Have been drinking alcohol, though, nightly for more than 60 years, but tests show no liver, kidney, heart, or lung issues. Sleep and exercise, plus good diet, make up for a lot of sins.
