How Much Sleep Do College Students Actually Get?

Last updated July 27, 2026

The most recent national figures come from a survey of 103,639 US college students conducted in Spring 2024. On a typical weeknight, the most common answer was seven hours — reported by a third of students. But 42.6% reported six hours or less, and only 24.3% reported eight or more, against guidelines recommending seven to nine for this age group. The more telling number isn't hours at all: asked how many of the previous seven days they'd got enough sleep to feel rested, just 9.1% said six or seven days — and 17.7% said none.

Key takeaways

• 42.6% of students sleep six hours or less on a weeknight; 16% sleep under six.
• Only 24.3% get eight hours or more on a weeknight — but 57.7% do on a weekend night.
• Just 9.1% felt rested on six or seven of the last seven days. 17.7% felt rested on none.
• 22.9% reported feeling tired or sleepy during the day on all seven of the last seven days.
• 30.6% take longer than half an hour to fall asleep; 10.7% take over an hour.
• Roughly three quarters of students in the largest study to ask said they had never received any sleep information from their university.

Did you know?

Students more than double their odds of a full night on a weekend. Only 24.3% get eight or more hours on a weeknight — on a weekend night, 57.7% do. The share sleeping six hours or less halves, from 42.6% to 21.1%.

That looks like students catching up, and in one sense they are. But the gap itself carries a cost: shifting your sleep by several hours every weekend moves your body clock, which is why Sunday nights are hard and Monday mornings are worse. Students aren't only under-sleeping. They're under-sleeping and re-scheduling themselves twice a week.

How many hours students actually sleep

Here's the full weeknight distribution from the Spring 2024 survey:

Two things stand out. The single most common answer is seven hours, which is inside the recommended range — college students are not, on average, catastrophically deprived. But six hours is the second most common answer, reported by more than a quarter of students, and everything at or below it accounts for well over four in ten.

Six hours matters as a threshold. Research tracking first-year students found that below roughly six hours a night, the relationship between sleep and grades inverts — sleep stops helping academic performance and starts hurting it. On that measure, a large minority of students are sitting on the line or under it as their normal week.

The number that matters more: how rested they feel

Hours are a crude measure. Someone can spend eight hours in bed and get poor, fragmented sleep. So the survey also asked a more direct question: on how many of the last seven days did you get enough sleep so that you felt rested?

Read the top and the bottom together. Only 9.1% of students felt rested on most days of the week — six or seven out of seven. 17.7% didn't feel rested on a single day. Nearly twice as many students got through the week without one restful night as got a properly rested week.

And more than half — 56.8% — felt rested on two days or fewer. For most students, feeling rested is the exception rather than the ordinary state.

What that looks like during the day

The consequence shows up in the same survey. Asked how many of the last seven days they had felt tired or sleepy during the day:

• 22.9% said all seven days.
• 44.3% said five days or more.
• Only 3.8% said none.

Roughly one in five students spent every single day of the last week tired. Fewer than one in twenty had a week without it.

Falling asleep is its own problem

Short sleep isn't only about going to bed late. A substantial share of students struggle to fall asleep once they're there:

• 10.7% take more than an hour to fall asleep on a typical night.
• 19.9% take between 31 minutes and an hour.
• 7.8% had an extremely hard time falling asleep on all seven of the last seven days.

Around three in ten students routinely spend over half an hour lying awake. That's not a scheduling problem — it's a different mechanism entirely, and it responds to different things.

Why isn't anyone fixing this?

The obvious question is what universities are doing about it, given they track and campaign on almost every other student health behaviour.

The best answer comes from an earlier analysis of the same survey family, covering 55,322 students: researchers found that roughly three quarters of students reported never having received any information about sleep from their university. In the same analysis, sleep problems predicted lower GPA at least as strongly as stress, binge drinking and drug use — the three things campuses do run campaigns about.

That question has since been dropped from the national survey, so it hasn't been re-measured. But the picture doesn't appear to have changed: writing in 2025, sleep researchers were still describing university campuses as an underutilised venue for sleep education, and arguing that teaching students about sleep represents an unrealised opportunity for population health.

So what actually helps?

Two things are worth separating. The first is that most standard sleep advice was written for someone with a private bedroom, a thermostat they control, and the same schedule every day — which is why it reads as useless to a student living in a dorm on a timetable that changes daily. We go through why in Why Doesn't Standard Sleep Advice Work in College?

The second is that the things that do work in a college setting are environmental and behavioural rather than purchased. No supplement lowers the temperature of a room you don't control or changes what time your body thinks it is. How to Get Better Sleep at School covers what actually moves the needle, and Do Sleep Supplements Work for College Students? covers what doesn't.

Frequently asked questions

How much sleep do college students actually get?
In a Spring 2024 survey of 103,639 US college students, the most common answer was seven hours on a weeknight, reported by 33%. Some 42.6% reported six hours or less, and only 24.3% reported eight hours or more. Guidelines for young adults recommend seven to nine hours.

What percentage of college students are sleep deprived?
It depends on the threshold. Of the 103,639 students surveyed, 42.6% reported six hours or less on a weeknight and 16% reported under six. A more revealing measure is how rested they feel: 56.8% said they got enough sleep to feel rested on two days or fewer out of the previous seven, and 17.7% reported no such day at all.

Do college students feel rested?
Mostly not. Asked how many of the previous seven days they had got enough sleep to feel rested, only 9.1% said six or seven days. 17.7% said none. Separately, 22.9% reported feeling tired or sleepy during the day on all seven of the last seven days.

Do college students sleep more on weekends?
Substantially. 24.3% reported eight or more hours on a weeknight compared with 57.7% on a weekend night, and the share sleeping six hours or less halves from 42.6% to 21.1%. That weekday-to-weekend gap carries its own cost, because shifting sleep by several hours each weekend moves the body clock.

How long does it take college students to fall asleep?
About 41% report falling asleep within 15 minutes. At the other end, 19.9% take between 31 minutes and an hour and 10.7% take more than an hour — so roughly three in ten take longer than half an hour on a typical night.

Are universities teaching students about sleep?
Largely not. In the largest study to ask, roughly three quarters of students reported never having received any information about sleep from their university. That question has since been dropped from the national survey instrument, so it hasn't been re-measured — but researchers were still describing campuses as an underutilised venue for sleep education in 2025.
