a short sleeping!

I do know a friend who slept only 4 hours a day. He claims that if he sleep more than that, his mind can't work! I have insomnia from time to time so I know the kind of frustration tossing and turning on the bed. Well, if you are feeling sleepy when you get up, you feel really tired during the day, and this has been unusual for you for some time, then you need to do something about it. Did your habits/work change? Are you facing some kind of stress? Did you take something with caffeine before you sleep? observe yourself and your life recently and you will get to the root of the problem.

Less than 4 hours? I can't image that. I may be crazy if I sleep less than 8 hours one day. But I also sleep very late in the night although I know it is not good for healthy. I think it depends on habitus because I know somebody keep energetic even they sleep quite little. Maybe you belong to the person who have a high recovery rate. Just relax and keep a good emotion, do not think too much about it. But still remember, turn to the doctor if you do not feel well.

Depend how much busy i am , but i am lucky because my body need just 5,6 hours for sleep, i don t need more. Specialist say that a normal human need 8 hours to sleep and feel good, but not all peoples are same.

Maybe you have some things to think about.Calm down,think about the reason why you can not to sleep and solve it quickly.Maybe you can sleep a short time after lunch.I hope you can slove the problem.
