College students are the most sleep-deprived demographic in America. About 70% report getting insufficient sleep, and the average college student sleeps about 6 hours per night. Between classes, studying, socializing, and part-time jobs, sleep is the first thing to go. But the academic cost of sleep deprivation is staggering.
The same as other adults: 7-9 hours per night. The American Academy of Sleep Medicine recommends at least 7 hours for adults aged 18-25. Most college students need 8-9 hours because their brains are still developing and they're learning new information constantly.
A study in Nature Human Behaviour found that sleep-deprived students had lower GPAs, worse test scores, and higher rates of academic probation. Another study in the Journal of American College Health found that each additional hour of sleep per night was associated with a 0.07-point increase in GPA. Sleep is literally worth grade points.
Sleeping until noon on Saturday creates social jet lag that makes Monday morning terrible. Keep your weekend wake time within 1 hour of your weekday time. You can go to bed a little later, but don't sleep in more than 60-90 minutes.
A 20-minute nap between classes can help bridge a short night. But don't nap after 3 PM or for longer than 30 minutes, or you'll have trouble falling asleep at night.
If you study, eat, and watch Netflix in bed, your brain stops associating the bed with sleep. Study at the desk, eat in the common room, and use the bed for sleeping.
Stop drinking coffee by 2 PM. A 3 PM study session fueled by caffeine will make it harder to fall asleep at midnight, even if you feel tired.
If your roommate keeps different hours, negotiate sleep rules: headphones after 11 PM, no overhead lights after midnight, quiet hours. Most roommates are reasonable if you ask.

Almost never. Sleep-deprived brains can't consolidate memories properly, so what you studied at 3 AM is poorly encoded. A study at UCLA found that students who sacrificed sleep to study actually performed worse on exams than those who slept and studied less.
Partially. Winter and summer breaks are good for repaying sleep debt, but it takes several consecutive nights of adequate sleep to fully recover. One long sleep doesn't undo months of deprivation.
Earplugs, a white noise machine, or a fan can mask roommate noise. Eye masks block light from their late-night studying. If noise is a persistent problem, talk to your RA about room changes or quiet hours policies.
Low-dose melatonin (0.5-1 mg) can help reset your circadian rhythm if your schedule is irregular. Don't use it as a nightly sleeping pill. Focus on consistent wake times and light exposure first.
