“In a study of more than 2,800 participants, those who slept less than five hours per night were twice as likely to develop dementia—and twice as likely to die—compared to those who slept six to eight hours per night.” (Emphasis added) From an article: Dementia Prevention in Clinical Practice, sourced to Robbins R.

I’ve typically limited my sleep to four or five hours because “I had so much to do.” Over the last six months, I’ve been moving my sleep from that number up to six hours per night, and now I’m working on getting it closer to seven hours per night. Within the next month, I plan to be averaging at least seven hours per night.
