Do we need 8 hours of sleep every day? I sleep less and less as I get older. I wake up early and want to get going on the day. It doesn't feel like it's for stressful reasons, but for happy reasons, enjoying life. I go to bed too late because I work in the evenings and don't wind down, plus I want to read in bed before going to sleep. I think I only sleep about 6-7 hours a day. I have catch-up days where I sleep almost 8 hours. Is that bad? I feel okay. I used to sleep much more. I wonder if I need less sleep since I am more healthy than I used to be and my body doesn't have to work as hard to remove toxins.
