The (Genetic) Science of Sleep: Brainstorm Health
Happy Friday, readers!
The University of California, San Francisco (UCSF) is out with a fascinating new study on why some people can, comfortably, get through their days with just four to six hours of sleep on a consistent basis. Called the science of sleep.
What drives this phenomenon (at least for a slice of folks)? Mutations in a number of genes (the latest study, 10 years in the making, examines a second gene after the preliminary discovery).
Here’s a broader writeup of the new report. Don’t fret too much, though. These specific mutations are pretty rare. And I hope, regardless of your sleep habits, you have some fun and get some rest this weekend.
We’ll be offline on Monday, September 2 for the Labor Day holiday, but back in your inbox on Tuesday. Read on for the day’s news, and have a wonderful three-day weekend.
