Depends for me.
If I can get my hands on ZMA (supplement consisting of; Zinc, Magnesium, & Vitamin B6 in a specific ratio) I have no problem operating (including a 2 hour morning gym session) on 6 hours.
If i can't get my hands on ZMA, 7.5 is ideal. Anything more than that causes sleep exhaustion and I just get lazy.
i usually get about 6 hours sleep a night
4 hours. But I can sleep for 10, 12 hours. =)
I'm good with seven hours a day, although I need at least one "sleep-in" a week. Hubby needs eight, nine is best, or he gets cranky.
I can get away with 6 hrs
Five for me on an average night.
I try to get 8 on work nights, but I can manage with less.
I can function on about 4 or maybe a couple power naps a day for a short while but honestly I should be getting 8-9 hours.
I would love 8 hours sleep a night. No matter what time I go to sleep I always wake up before any alarm at five in the morning. Force of habit.
But some of the jobs I've had never allowed that much. (I worked on an oil rig, for a lumber outfit and worked at jobs where my hours would be changed every week.) The longest I've gone without sleep was just over 4 days once when I was sick and a little more than that once in the Navy when my duty section was not scheduled for any sleep for a week. I fell asleep at the helm so I know I was the last guy to fall asleep in the crew and I was also the first to wake up as when I lost my balance the first thing I did was look at the compass and saw I was 70 degrees off course. There is no way I could get away with that from the engine room to the bridge if anyone was awake. I must had slept at least a half hour on my feet. It took me the rest of my watch to get the ship back on course one and two degrees at a time to keep from waking anyone. Just at the end of the watch, at 4. a.m. when it was time to wake the crew I heard people moving around on the bridge and I was on course.
We had had bad weather the first three days so it was hard to sleep even when you were allowed, but just before I went on watch at midnight on the fourth day the seas got clam and everyone relaxed and fell asleep. As it turned out the scare kept me awake for another day or more and then I remember after being relieved from watch going to my work station on the fantail and putting on the phones and looking at the false sunrise. The next thing I knew I was hearing a loud voice in the phone and after looking around and rubbing my eyes because it was so dark I couldn't see my hand realized they were talking to me. I found out I was in a different part of the ship and asked the bridge who was yelling at me what our duty condition was. A very stupid question, but the guy just cussed me and told me and I found out I was in the right spot. I looked at my watch and it was almost midnight. I had walked in my sleep from before sunrise till then. That kept me awake till the last day when my petty officer looked at me and said go cold body which meant go find some spot to lay down and when I need a warm body I'll kick you up.
I've also blacked out three times after going with very little sleep. Blacking out means that you go dead to the world and no one can wake you no matter what they do to you till your body lets you.
It wasn't unusual to go two full days or more without sleep in the service. After I got out my jobs would require me to get up at times during the night or to get up very early and of course any free time I got I didn't want to waste sleeping so I went out. The job I have now has regular hours and days and is great.
But if I do get 8 hours I find I feel great.
I need 6, I frequently get about 5 during the week, and I love the 8 hour catchup one day on the weekend
8 is my ideal, but I can get by on less. I've gone for days with less than 5 hours of sleep a night, but eventually it gets to you.
On a daily basis I would have to say 5 hours asleep.
I need 8 hours every night, otherwise I'm cranky.. In the weekend If time permits I would sleep in so I would go up to 10 hours..
When I was in college I worked two full time jobs and went to school full time. I learned to do quite well on 4. Besides, I figured doing that effectivly added 72 days to my year wiith 20 hour days.
And, yeah, ABSOLUTELY NO social life. In 4 1/2 years or so I got two degrees with four majors.
Now I'm 71 and I'm up to 4 1/2 to 5 a day. So for the last 50 or so years I've added 3,600 days or about 10 effective years to my life. I've had a lot of sex in those 10 years. Worth every second of it.
I need 8 or more I like sleeping.
I am good to go on 4-5 hours of sleep. Always have been a light sleeper..
I need a minimum of 8 hours; 9 preferred. I feel quite drained on less than that, as I'm very active and used to feeling full of energy. To be honest, I suspect that some people just feel sluggish all the time and couldn't tell the difference. I have to be careful not to oversleep though, because it can easily make me not fall asleep the next night and mess up my sleeping pattern, which is kind of sensitive to disturbances.
Very rarely that I need more than 5 hours of sleep.
4-5 depending. PTSD and years of working the midnight to 8 AM shift have left me with an best disjointed "sleep pattern".
4 to 5 hrs is about all i get sometimes less. I feel like I need more to be at my best, 8 would be great.
Depends who is in bed with me and what means she employs to convince me I don't really need that much sleep!!
Now there are a few contenders for whom I would sacrifice sleep but I do need a few hours...
To regenerate my senses and energy, I need about two hours, facing a hard day, about 6 hours
