Sleep is primarily seen as a neurological phenomenon, and yet when deprived creatures die, they have a puzzlingly diverse set of failures in the body outside the nervous system. Insufficient sleep in humans and lab animals, if chronic, sets up health problems that surface over time, such as heart disease, high blood pressure, obesity and diabetes. But those conditions are not what slays creatures that are 100% sleep deprived within days or weeks.~ Corey Brickley from, https://www.quantamagazine.org/why-sleep-deprivation-kills-20200604/
I’ve said it many times here, and I will keep saying it: Sleep is the single most important thing. In your life. Literally. If you are not sleeping well, and long—like, 8 hours per night, long—you have a serious health issue; not sleeping well, and sufficiently is a serious health issue.
Yes, insufficient sleep—not, “I don’t feel sleepy,” but not getting sufficient sleep—if you don’t feel sleepy… if you are not sleeping 8 hours… you have other problems which are affecting your sleep. Insufficient sleep has direct causal relation to Alzheimer’s. Scared enough to fix your sleep yet?
Listen to the podcast, then buy the book, Sleep Smarter. It’s an easy introduction to how to fix your sleep. Or, don’t sleep well, die sooner and get Alzheimer’s; it’s your choice.
