I'm reading a great book at the moment about Sleep which suggests having 8 hours sleep into older years is linked to avoiding alzheimers. It suggested that nrem sleep performs a nightly clean of the brain. As I enjoy sleep I'm in favour
I am doing the exercise and healthy eating, but I have a worry of my sleep pattern. I only sleep 5-6 hours each night. I go to bed around 10:30PM. After listening to a podcast, I fall asleep at around 11:00 PM. By 4:30AM I wake up naturally and can't go back to sleep again. I may take a nap for 15 minutes during the day, and that is about it.
I am 63 now. For all of my adult life, I do not remember I ever sleep more than 7 hours. So do I simply not need much sleep comparing to other people, or I am in trouble?
