How many hours do you need to sleep well?

I need about 7 to 9 hours before I feel well-rested for a whole day.

I know there are people who only needs 5 hours, and people who needs 10 hours. It obviously varies a lot from person to person - and I think it's important to find out when you get enough sleep.

They say a golden rule is that if your alarm clock wakes you up - instead of you waking up on your own accord - you ha

I need 8-9 hours a day.

I heard a gold rule: 8 hours to sleep, 8 hours to work, 8 hours to play = 24 hours

I love the gold rule . I'm going to consider it in my schedule

I have read that traditionally, it was normal for people to sleep for 4 hours, wake up and read or talk with neighbors for an hour or so, then sleep for another four (called the second sleep). Quite interesting.

I need at least 5, I prefer 8+ though!

We can sleep like Leonardo da Vinci - every 5-th hour

4 hours to work - 1 h to sleep - 4 hours to work - 1 h to sleep - 4 hours to work - 1 h to sleep - 4 hours to work - 1 h to sleep - 4 hours to work = 24 H

So, he could work all day and all night long

I need between 7-8 hours to sleep if I want feel myself in good mood and shape.

It would be enough 6 for me because as usual I cannot sleep. When I sleep all night, more than that or when it happens to sleep 9 hours, for example, I feel I can fly.

8 hours is pretty enough to me generally.

At least 4.5 hours, 6 hours are enough and 8 hours are prefect indeed~

I'm student, and when I study for exams I sleep 6 hours. When I'm at vacation I sleep longer, and when I wake up I feel tired...
