How many hours' sleep do you need?

I work on graveyard shift and I need to get at least 7 to 8 hours of sleep and if I dont get enough sleep, I get so cranky.

I have always have problems sleeping even when i was a child so i am grateful if i get a solid 4 hours sleep a night

I need around 8 hours. Unfortunately, there are many nights that I wake up in the wee hours and have a hard time getting back to sleep.

I usually need about 8 hours but i have a small child so she doesn't sleep through the entire night. i get about 11 hours of broken sleep, that's waking up 3-4 times a night sometimes to feed her. *sigh* its not a good sleep. but its a long sleep :P

Usually, when I get a seven to eight hour sleep, I feel myself full of energy. But now, since I have joined mylot, I spend more than two hours typing in front of the screen. I seem to need more sleep. I don't know why? My eyes just want to close and rest even in the morning.

I usually sleep for about 7 hours and after 7 hours of sleep in night, I don't feel sleepy during the day. As luckily I am a very sound sleeper. So this 7 hours sleep recharches and freshens me for the day.... :-))

i have a very active lifestyle, i work 8 hours a day and do sorts of exercise for 3 hours everyday, so i do need to sleep a lot. i require 8 hours of sleep each day. but on weekends i would stay in bed up to 10 hours though

I sleep atleast 7 to 8 hours a day. I think everyone has to enough sleep otherwise we feel drowsy all the day and we will not be able to work properly.

my perfect sleep, will be 8 hour minimun each day.Lest than that, i feel tired. sleeping kind like a hobby to me. a wonderful dream that God give me during my sleep,will be a bonus^o^

I love to sleep, well actually I love to dream. I usually sleep between 8-10 hours. I don't set my alarm unless I have to get up early. Most of the time if I'm not disturbed I will sleep 10hrs. Now that I can sleep as much as I need to since I'm out of work on disablility, I see how this was a problem when I couldn't. I didn't realize that I just need that much sleep. Don't get me wrong, I am quite functional on 7 or 8 but I need to use an alarm for that amount of sleep.

I sleep about 6-7 hours per day.... coz I've ever read once that people who sleep 8-9 hours in a day would have shorter ages than they who sleep less than 8 hours.

i have different sleeping hours. I need 8 hours or more for me not to get sleepy. But because of so much things to do, i have less hours of sleep. But i require my self at least 6 hours for me to have some energy for the day. I easily get weak when i have less hours of sleep. its often that i could not wake my self if i have less than 6 hours sleep.

That's true according to study, human needs to sleep at least eight hours. But in my situation, I used to work at the office from 9 a.m. to supposively six pm. But i used to have overtime works. I went home about nine in the evening or late as 11 pm. We have company activities every friday and I usually went home as late as 12 midnight and I still have office work the next day but only half-day during saturdays.

they said, it is the quality of sleep not the quantity... there are some guides to get a quality sleep... you can search it.... yes, a 8 hours sleep will do...

Well I guess I need about 8 to be fully relaxed but all I ever get is 4 hours of sleep if Im lucky.

yeah abt 6 to 8 hrs for mee too but more sleep i get the better

i have lost my sleep and for the past 5 months. i dont feel sleepy all day

Normally i need 8 hours of sleep. But i think its requirement of each and every people to sleep 8hrs. Many people sleeps 4/5 hrs and many 10/12 hrs its totally depand with peoples nature and workloads.

i usually sleep for about 4-6hrs. i find it hard to sleep especially when the sun is aleady up...and i usually sleep early in the morning...
