how many hours of sleep you need ?

If I Haven't Work I Can Sleep Or I Need Sleep At least 10-12 Hour... But In When I Have Work I Got enough By 4-7 Hours In Day

i need 6 hours if the next day i'm working. if its holidays, 2 to 3 hours is ok. cause i can sleep again later on.

It varies but I think I need eight hours of sleep. I haven't had a good sleep for like ages. There are even times when I think I have slept for seven straight hours but after about half an hour, I feel sleepy again. Someone said that that's a sign of high blood pressure but I am not really sure. And there are times when I would have a really intense dream and feel really tired when I wake up. I usually stay up late when we have things to do in our internet cafe, or watching television shows or movies or reading a book. Well, I don't fall asleep easily and sometimes I use those so that I will feel sleepy.

I am a pig, I need at least 8-10 hours. Recently I did not sleep for 1 night because of projects and I slept for 20 hours the next night. LOL

People keep saying we need 7-8 hours of sleep. Apparently, Donald trump sleeps only five hours a day. How come he doesn't look like crap and can still keep his edge.
