How many hours and when do you sleep everyday ?

Generally I do not prefer to wake whole night.When I was student I used to study at late night due to calm atmosphere but the very next day I feel heaviness in my body.Dark circles develop under my eyes.I feel drowsy during day time. I change my habits slowly and now I perfer to sleep at night.

I don't typically nap during the day unless I stayed up all hours of the night before. My typical bedtime is between midnight and 1am, and I am usually up by 5 or 6am... I don't seem to need as much sleep as most people, but I certainly need more than I did when I was younger. As a child, I did not know how to sleep, and could go for weeks on end with no seemingly sleep at all. I can no longer do this and need four to five hours per night at bare minimum.

I go to bed at 11 p.m. and get up by 5 a.m. As one advances in age, one gets less and less sleep and ultimately it comes to 5 hours. But then in the afternoon one needs an hour rest. I do not wake up in midnight and also I maintain the timings for sleep:

Yes, I know a lot of people in my lab who like to work in the night, and go back to sleep in the morning. Sometimes I have experiments that must be done at night, I will feel very uncomfortable, and although I sleep the whole day after that, I still feel sleepy and headache. Night is for sleep, so it is not right to make that time awake. I spend about 7-9 hours per day to sleep, from 0am to 8am usually.

Hmmpp... I slept for almost 6-8 hours a day. I usually sleep at 11pm-1am and wake up at 7-8am if have no work. 6am if with work.

There is only one night kept staying up,that's a night when i am a college student. You know,there's less stress as a student,we can sleep well,but during that time,we are in the golden days of our life,we have passions on everything,our emotion change quickly like the weather,we are crasy indeed. So guys together play games will forget sleep, to sing songs in KTV will forget the night,to review books in order to pass the coming exam will spend the whole night...and so on. As for me now,i'm working about 8 hours a day,i will almost take 8 hours to sleep,if it's a sound sleep,i will work well with energy.

I go to bed around 10PM and wake up about 5AM. Getting up this early I cant stay up very late. Although I am a night person and would love to stay up all night.

I love sleep.Because I do not have enough time to sleep.I like sleep from early night tonext morning about 7:o0
