After the Workout - Day 3

Sleeping is my topic of choice today. How much sleep do we need and how do you know when your getting enough? I've read dozen of articles over the years and I am never convinenced that someone knows it all when it comes to sleeping. I've heard things that you are supposed to get at least 8 hours of sleep, when your young. I've heard that you enter REM cycles every 90 minutes, so you should set your sleep schedule around that. I did that for a few years in high school and in college. Lately, I've read this great article by Steve Pavlina on Polyphasic sleep. It was were he was awake for 3 hours, then took a 20 minute nap. And he did this for about 5 months. You can read about it on his website. Just incase you don't see, he would be awake 22 hours a "day" and sleep only 2 hours. The guy is much older than me, so it makes me wonder again, how much sleep do we need? I always try to make my sleep time around 6 hours. I saw that, but some nights I sleep in longer. Today is was about 7. Its not because I ever want to get more than 6, but I forget to set my alarm clock and such. Well, just thought I would put that out there. Have a good weekend everyone, and I'll see you tomorrow morning!
