Sleep is closely related to health. My dear friends, how long do you sleep every day? Is it up to seven hours? Welcome to join the discussion!

Thank you .From your message, I know seven hours of sleep are enough for everybody. I'll insist seven hours of sleep everyday.

Exactly calculating，I sleep for eight hours per day.I have developed a habit that get up at 6.00Am and go to bed not late than 10.00Pm，if nothing special to deal with. Fortunately for me，I have every sound sleep every evening . A good sleep can provide adequate energy for next day work or daily life. Further more ，can make one person healthy and energetic，both in phycical and mental.

I was get off at night before I had eaten snack. Ensure that every day there are 10 hours

of sleep time. There are sufficient to meet the challenges of energy.

A regular sleep form extraordinary affect.therefore,the adapt habit source biological clock. The biological clock regularize times because you have done schematic schedule.you must done satisfactorily.the right sleep provide smart head and syllabify thinking.

You ought the red jujube, the honey, the milk.

for me ,a new pople in my occupation,to keep enough time of sleep is a little difficult thing.Four years of schoollife make me keep unregular life.Almost everyday we went to bed at 23:30,and then wetalked ,perhaps we really slept at 24:00.Now,I go to work day,and night surf Internet.I can sleep at 23:00.Though it is also late ,I still believe I can develop the habit of sleeping eraly step by step.

oh, I sleep less than 7 hours during schoollife.But now I am on summer vacation,I have a

chance to sleep longer.It is up to seven hours. Now I discover that sleeping for a long time is not good. i will try to sleep earlier and get up earlier.

Generally speaking, seven hours of sleep is best for us . If you sleep much longer or shorter, you will feel tired and dispirited.

We should develop a habit in sleeping.

Every day I go to bed time is not fixed. But with age, I sleep less and less time.In primary school, I usually sleep 9-10 hours. On the high school, is 7-8 hours。I am afraid of what would happen on a college。

Eh, we need to take sleep Rights
