is there any point in studying if you I slept 5-6 hours last night? I know jackshit about neuroscience, but I do know that it's pretty established that cognitive functions are all fucked up unless you sleep 7-8 hours uninterrupted.
So am I better off using the day to clean the house and doing other mindless shit, or could I still retain information if I study?

Depends on the kind of studying you're doing. If its rote memorization and reading, then yeah you probably won't remember much. If its practice problems and exercises, then you'll remember it all pretty well no matter how little sleep you've gotten. Doing some exercise and other activities would also be a benefit, and never study while laying on your back or stomach.

I would take a walk and buy some earplugs at Walgreens, then eat a banana and take a nap after putting the earplugs in.

just isn't true.
go see polyphasic.net
autists conducting nap science.
personally, i learned best after a mid-day cat nap of ~13 minutes regardless of the night's sleep. if I dreamed during the nap, I would always wake up completely alert and able to comprehend what I studied.
also studying the same thing for a few minutes everyday (or every few hours) is better for retention that just studying once for an entire day

Has anyone tried segmented sleep? apparently it was the norm for most of human history up until the introduction of artificial light. People would get up in the middle of night to pray, eat, have sex, etc., then go right back to sleep and wake up four hours later.

Is there any point in studying at all?
From my experience in STEM, they load you up with so much work that it's impossible to actually learn anything, you just desperately sprint from one deadline to the next while your health deteriorates and you struggle to keep paying your bills.

5-6 hours is about enough to do daily function normally, if you can stay on task and focus then it should make no difference. The night after is what really matters, not before.
>So am I better off using the day to clean the house and doing other mindless shit, or could I still retain information if I study?
Non sleep deep rest to some degree acts similar to sleep and is very beneficial if you do it right after a study session.
Exercise will also offset a lot of the downsides of less sleep. I've read some arguments that hunter gathers only need to sleep 6-7 hours because they actually exercise daily.

this belief was popularized by the book "Why We Sleep" but the science and history behind it isn't conclusive at all. The consensus among sleep researchers right now is that it probably isn't a good idea

i had a short bout of waking up after ~4 hours of sleep every night for like a month. shit sucked, especially if i decided to not try to go back to bed immediately and jerked off or even got up to get water instead. was always tired during the day. its possible to feel ok because most of our deep sleep is in the first half of sleep but without somewhere between 6-8 hours of good uninterrupted sleep you will feel noticably shittier.

7 to 8 hours uninterrupted sleep is a myth. I think people who claim they get that are lying or mentally insane.

In high-school I always had only 6-7 hours a night. The caveat is that I would nap on the bus or when I got home. I personally think it helped me retain information because trying to nap gives you a chance to think about what you did for the last 6 hours. Got straight As doing this and was easily top of the class. If you are very tired and focus / study then have a nap, you will be refreshed and remember everything even better.

Low sleep being bad for you is a meme. You're more healthier getting 5 hours than you are 9. Some people are just born lucky and need only 4 hours (the 'thatcher gene') and they get 4 extra hours awake every day. Anyone insisting you need 8 is just coping hard.

https://en.wikipedia.org/wiki/Insomnia#Prognosis
>A survey of 1.1 million residents in the United States found that those that reported sleeping about 7 hours per night had the lowest rates of mortality, whereas those that slept for fewer than 6 hours or more than 8 hours had higher mortality rates. Getting 8.5 or more hours of sleep per night was associated with a 15% higher mortality rate. Severe insomnia – sleeping less than 3.5 hours in women and 4.5 hours in men – is associated with a 15% increase in mortality.[145]

Damn it, I feel you. Got 28 credits this semester and I can't learn jackshit. It's list after list after list after seminars after exams and I can't even think about all the shit I'm speedrunning just to barely survive.

I take a 15 minute cat nap every day too. I rarely ever remember my dreams during normal sleep but somehow almost always do after a short nap.

Correlation is not causation, retard.
Most people that sleep 9 or more hours are physically ill, or suffer from the chemical imbalance form of depression, all things that lead to lower life expectancies and lower overall health.
Those that sleep very small ammounts, are those that have the drive and energy to do so, i.e. those that healthy enough to get away with it. Which will show in them being much healthier than they'd be supposed to.

except 5 hours has a lower mortality rate than 8 hours, retard. If 8 hours is so healthy then how do you explain that?

You literally said in your own post that certain people can achieve that through genetics.
Do you really think those that aren't genetically gifted wil be forcing themselves to sleep 3 hours less?

No, I said that certain people naturally sleep only 4 hours (Thatcher had it, trump has this too). There's no explanation for why 5 or 6 hour sleepers should be so healthy, unless the 8 hour rule is all bullshit

no it says that sleeping >8 hours or <6 hours is associated with a higher mortality rate than 7 hours (the lowest) which is true. The actual article cited shows a lower hazard ratio for 5 hours (1.11 for men) than 8 hours (1.12 for men)
