What is the best time should we go to sleep?

i usually go to bed at 12 and get up at 8 during the week.

When we are tired.

I don't know if I agree with this, however I was watching a program on A&E TV and it said that people should sleep an hour after sun down and awake at sunrise. More or less it was something about how the trees produce oxygen at certain times blah blah blah. Anways, I sleep when my body tells me. Though a routine is certainly necessary, but not for me.

10:00pm,i have saw it in a book!

I usually try to go to bed by 11pm, so that I can be up at 6am for my kids. But sometimes I do not go to bed till 2am, which gives me about four hours of sleep.

For me I just go to bed when I am tired ,and its around 11:00 pm. and I get up at 6:30am. And on weekends I stay up untill 1:00 to 2:00 am then go to bedand I get up around 8:00 am.

It depends when you have to wake up. I think one should get a good nights sleep of about 8 hours.

It deepends when you have to wake up. I think one should get a good nights sleep of about 8 hours.

for better health, we suppost to sleep 7-8 hrs. better sleep is between 10pm-7am. I am in my bed when I am tired, get up at about 8 am.

I perfer to stay up at night if I could but work kinda gets in the way .I work at home a pet groomer by appointment so I know when I have to get up to work .I set my shedule according to when I work I figgure out that I get about 7 hours sleep thats my ideal sleep amount then go to bed so I get up with that amount .If I work at 10 am I get up at 8:30 am so don't have to go to bed early if I have to get up earlier I go to bed earlier if later vice versa .

I usually go to bed about midnight. I use to go to bed earlier but I don't get up as earlier now and I don't need as much sleep as I use to. I don't think it matters when you go to sleep as long as you get enough of it.

The best time that we should go to sleep is 22.00 hours by standard time. Another criterion is there, that is about 3 to 4 hours after Sun set. Thanks.

For me I need to keep a pretty regular schedule, being bipolar I have learned that boundaries and routines make my life less stressful so I try to be in bed by 11 pm at the latest. My younger sister also has sleep issues and she said that she was told by her doctors that adults should be in bed by 9 pm each night, so her whole family follows that schedule. I would like to just follow by biological clock, but mines messed up so I tried to stick to the 11 pm up no later then 7 am routine :)

I go to sleep an ten oclock pm

Everyone is different and don't need the same amount of sleeps. I don't think there is a best time we should go to sleep. For myself I usely go to sleep at 9h30-10 because I have to wake up at 5 to go to work. When I don't work IT,s usely between 10-11 that I go to sleep and I wake up between 8-10 the next morning. I need a lot of sleep
