how many hours should a normal humanbeing needed to sleep..?

man should sleep atleast for 8 hours

For children, 8 to 9 hours, For elders, 5 to 6 hours, For old people, 4 to 5 hours is enough

I think it's different to each person, but it should be around- 8-9 hours. I know that here the average is 6-7 hours, so we don't really sleep enough I suppose x_X

I usually only sleep ( in non holiday ) about 4 hours minimal and 6 hours maximal, i usuall sleep for about 5 hours. In week end i can sleep about 6 to 7 hours. I don't have any problem at all since i do this a very long time already. Also, i think the quality of sleep also takes bigger roles of how long a human should sleep. Sleeping with dream in a place where there to much light and sound will make your sleep quality poor and you will not heal as much as you should be.

hey try to sleep less you can sleep more.... this is truee.... nce go with it....
