Heres a good question to all the sleep experts. I know you need 8 hours of sleep a night. But what happens when you stay up really late… say till 4:30 instead of 10 oclock and then still get your 8 hours of sleep… i know its worse… but since youre still getting 8 hours of sleep… are you still recovering?
I’m not a sleep expert, but I’ll chime in anyway. I don’t think the recovery will be as good. You body operates on a circadian rhythm and if you disturb it by staying up too late, I don’t think you can make it up by sleeping in. Not only is the quantity important, the quality of the sleep is also important.
Of course your recovering. My training buddy sleeps a total of six hours and thats split up into two three hour naps. His lifting is going fine so take your 8 hours any way you can and lift.
Our internal clock moves forward easier than it does backward as demonstrated by your ability to push your bedtime ahead 6.5 hours instead of backward.You probably don’t have a problem recovering from that delayed sleep unless your not eating anything in that time.Your real problem will be trying to return to the earlier bedtime especially if your staying up late several nights in a row.
it was a one time thing… i was trying to get some… the testosterone way… im in highschool i can do that right?
“It was a one time thing” huh? The “trying to get some” part or the sleeping late 
I work third shift and sleep from 6:30am till about 3:00pm and usually do fine. I agree with some of the other posts that quality is much more important than quantity. Cat Naps seem to help recovery aswell. The key is that you get into REM sleep. If you don’t get that it doesn’t matter if you sleep 12 hours. The best way to do this is to have a set pattern for sleep such as going to bed at the same time, brushing your teeth right before sleep, or taking a shower right before. A good sleeping environment also helps. Have your bed made with clean sheets every day. If you sleep during the day make sure the room is dark enough. I would also avoid physical activity before bed…well unless its a little nookie.
