I'm ENTp, and I've always been an insomniac. I remember being 5 or 6 and looking at the clock and it being 2:00 in the morning. I just can't seem to shut my brain off!
Studies show that people who sleep 5 to 7 hours a night are the most healthy. I used to think I was a 7 hour a night kind of girl, but I'm not so sure anymore. I think it changes a lot. Recently I decided that instead of trying to get in bed by a certain time or make sure I get enough sleep, I should just listen to my body and go to bed when I am sleepy. I believe taking the "should" out of bed time has allowed me a better quality sleep (well, it's sorta hard to judge atm, but it seems like it).
Anyways, do you think that your type influences your sleep habits?
