<p>There have been plenty of threads on this, I know. Anyway my preferable sleep is 9-10 hours a day, but lately I have been getting 5-6... (Swimming at 5am, sports afternoon till 5:45, MUN, APs, so forth), and I think with all that the sleep I get is good. However, I feel too groggy. On the other hand, if I barely sleep or get just a quick shuteye, I am just fine. </p>
<p>By “barely sleep” do you mean like 3 hours a night? I usually need 6.5 to feel fully awake, but if I get 3-4 I’m also good. Anywhere in between and I’m tired all morning. If I only get 3-4 for a few days in a row, I crash. Don’t recommend experimenting with that every day unless you are okay with sleeping through your alarm clock on Thursday and waking up at 1 pm.</p>
<p>I advise you not to sleep for 2hr, 2hr, then 1hr over the course of three days. I swear, 1 hour of sleep will kill you after a couple nights without it. </p>
<p>My thing is if I get between 4.5-6 hrs i feel really groggy thru the day. Getting to bed b4 11 is a pain (not like its that bad) but waking at 430/500 is tough.</p>
<p>Well it’s still summer time for me. I usually get a good 10-12 hours. Sleep at 3-4 ish and wake up 2-3.</p>
<p>When school comes around it will most likely be: 11-6. I take 2-3 hour naps after school. But honestly I can function pretty well without a lot of sleep.</p>
<p>there’s such a thing as sleep debt, which accumulates over time. 5 hours might feel worse the next morning than 3 hours due to sleep cycles, but over a long period of time 3 hrs/night will wear on you more than 5 hrs/night.</p>
<p>Sleep debt is a tricky thing because there are psychological and physical factors at work, rather than just physical.</p>
<p>Today I went to school on 3.5 hours sleep and felt horrible. My stomach hurt, my throat was dry, my eyes hurt, I felt like I was in a tunnel. But this is because I’ve gotten tons of sleep all summer.</p>
<p>If I fall into a schedule, I’m good with 4 hours a night. I get tired, but my mind adjusts and I don’t get these aches and pains. In between hours, like 5-6, somehow make me feel much more tired than 3-4, probably because my body switches to some sort of deeper sleep mode by the 5-6 point (I guess? Not sure).</p>
<p>Last year was insane though. There were at least 2 instances where I was up more than 30 hours straight (and I have a 50 min commute one way!), and many instances where I was up more than 24 hours straight. It’s bad when you have to drive. Real bad, and real stupid.</p>
<p>In my last week I actually had to get someone to drive me in because I was afraid of passing out at the wheel. I was on something like no sleep for 30 hours at the beginning of the week, than like 2hr, 2hr, 1hr, something like that. I was basically up all night, and had to try and finish my final project in the car ride while my mother drove me. I kept getting sick to my stomach and dizzy, and would just periodically slump foward and start fading out. It wasn’t even really sleep at that point.</p>
<p>Needless to say, when summer hit each full night of sleep was like an entire night of orgasms. I got so spoiled on sleep that now I’m in for a hurt world.</p>
