How to Stop Hitting Snooze: What the Research Actually Says (and What Works)

56% of nights end with a snooze (21,222 people studied). Is snoozing bad for you? What sleep research really says, and 7 practical ways to stop.

In short

  • Snoozing is the norm: 55.6% of sleep sessions ended with a snooze across 3 million nights from 21,222 app users (Robbins et al., 2025).
  • The evidence is mixed: 20 minutes of snoozing prolonged grogginess in a 10-person lab study (Ogawa et al., 2022), while 30 minutes did not hurt cognition in 31 habitual snoozers (Sundelin et al., 2023).
  • Snoozing is mostly a symptom of short or irregular sleep. To stop, set your alarm for when you actually get up, keep a fixed wake time, and make the snooze button hard to reach.

Your alarm goes off at 6:30. You hit snooze without opening your eyes. 6:39, again. 6:48, again. At 7:05 you finally sit up, late, foggy, and oddly more tired than if you had just gotten up the first time. You spent an extra half hour in bed and it didn’t feel like rest.

If that sounds familiar, you are in the majority. And the research on snoozing is more nuanced than the headlines claiming it “wrecks your brain.” The short version: snoozing is rarely the disease. It is usually the symptom.

How common is hitting snooze?

Very. The largest dataset to date comes from Brigham and Women’s Hospital researchers and the Sleep Cycle app: more than 3 million sleep sessions from 21,222 users on four continents. 55.6% of sessions ended with a snooze, people pressed it 2.4 times on average, and spent 10.8 minutes snoozing per morning (Robbins et al., 2025). Snoozing peaked Monday through Friday and dropped to its lowest on Saturday and Sunday. Heavy users snoozed around 20 minutes a day, and the US, Sweden and Germany were among the highest-snoozing countries.

Survey studies land in the same range. Among 450 working adults tracked with wearables, 57% identified as snoozers, averaging about 27 minutes between the first alarm and getting out of bed (Mattingly et al., 2022). In a survey of 1,732 adults, 69% said they snoozed or set multiple alarms at least sometimes, for an average of 22 minutes per morning (Sundelin et al., 2023).

Why do I keep hitting snooze?

The most common answer is boring and honest: you are tired. In the Sundelin survey, the top reason for snoozing was feeling too tired to get up. Snoozers were younger, more likely to be evening types (night owls), and slept slightly less than non-snoozers. The Mattingly study found the same pattern with evening chronotype, plus links to more disturbed sleep and lower conscientiousness scores.

Anxiety plays a part too. In a survey of 293 Japanese university students, 70.5% often used snooze, and the number one reason (50.7%) was reducing the fear of oversleeping (Ogawa et al., 2022). Most of them set their first alarm 30 minutes before they actually planned to get up, a built-in snooze window.

So if you snooze every day, the more useful question is not “how do I resist the button?” but “why is my alarm set at a time my body isn’t ready for?”

Does snoozing make you more tired?

The grogginess you feel after waking is called sleep inertia: a temporary dip in alertness and performance while the brain transitions out of sleep. Across studies, performance usually returns to baseline within about 30 minutes of waking, though full recovery can take an hour or longer, and it is worse after sleep loss (Hilditch and McHill, 2019).

The case against snoozing rests on two ideas. First, the sleep you get between alarms is fragmented, a few minutes at a time, rather than one solid block. Second, every time you drift off and get woken again, you restart the process of waking up.

One small lab study supports this. Ten students slept in a lab twice: once with a single alarm, once with four alarms 5 minutes apart over the final 20 minutes. After the snooze night, sleep inertia lasted longer, auditory reaction times were slower (238 ms vs 222 ms), and the boost in energy people normally reported after getting up didn’t show up (Ogawa et al., 2022). The obvious caveat: ten people is a very small sample.

The Mattingly study (n = 450) adds a physiological hint: snoozers had slightly lighter sleep in the last hour before waking and a resting heart rate about 1.6 beats per minute higher. Yet they did not sleep less overall and did not report more daytime sleepiness.

Is snoozing bad for you?

This is where the evidence pushes back. The most rigorous test so far, from Stockholm University, brought 31 habitual snoozers into a sleep lab with full polysomnography. Each person had one morning with an abrupt wake-up and one with 30 minutes of repeated snooze alarms (Sundelin et al., 2023).

What they found:

  • No cognitive penalty. Right after getting up, test performance was the same or slightly better after snoozing.
  • About 6 minutes of sleep lost out of the 30, since participants fell back asleep for more than 20 minutes.
  • No clear effect on the cortisol awakening response, mood, morning sleepiness or the night’s overall sleep structure.
  • No awakenings from deep sleep during the snooze period, which an abrupt alarm can cause.

Lead author Tina Sundelin was clear about the limits: the study only included people who snooze regularly and fall back asleep easily, and it tested 30 minutes, not an hour. It says nothing about people running on five hours of sleep.

The fair conclusion: a short snooze is not harmful based on the evidence available in 2026. Claims that snoozing damages your heart or causes depression are not backed by any published study we could find. The real costs are practical: fragmented sleep instead of solid sleep, a late and rushed start, and breaking the first promise you made to yourself that day.

If you are exhausted every morning despite long nights, see a doctor; persistent fatigue can have treatable causes.

How do I stop hitting snooze every morning?

The fixes below are sorted by what they target: the underlying sleep problem, or the button reflex itself.

1. Set the alarm for when you actually get up

If your alarm is at 6:30 and you get up at 7:00, you are paying for 30 minutes of broken sleep. Set it for 7:00. Rebecca Robbins, lead author of the 3-million-night study, gives the same advice: set your alarm for the latest possible time, then commit to getting up at the first one. Same time in bed, better sleep.

2. Keep one wake time, weekends included

In a 30-day study of 61 Harvard undergraduates, irregular sleep schedules were associated with a later internal clock and lower grades (Phillips et al., 2017). That is a correlation, not proof, but the logic is sound: a body that knows when it wakes up is less groggy at that hour. The Robbins data point the same way, with more snoozing after later-than-usual bedtimes.

3. Turn off the snooze button

On iPhone, open the Clock app, tap an alarm and switch Snooze off. The button disappears from the alarm screen. Since iOS 26 you can also choose a snooze length from 1 to 15 minutes. Not ready to go cold turkey? Allow yourself exactly one short snooze and no more.

4. Put your phone across the room

The classic works because standing up is the hard part. Once you are on your feet, getting back into bed takes a decision instead of a reflex. Its weakness: plenty of people walk over, silence it, and walk back.

5. Use a mission alarm

Mission alarms only stop after you complete a task: mental math, a memory game, a photo of a specific object. Alarmy, the best-known app in this category, offers photo, math, shaking, squats and step missions, among others (App Store listing checked on September 28, 2026). No published study has tested these apps against sleep inertia yet, so their value is practical: the button-mashing reflex becomes impossible. We compare the options in our guide to the best alarm apps for heavy sleepers.

6. Get light, but don’t expect a switch

Morning daylight helps anchor your body clock over days and weeks. Against sleep inertia itself, though, the two light-on-waking studies reviewed by Hilditch and McHill (2019) found no significant improvement in objective performance. Treat light as a regularity tool, not an instant wake-up button.

7. Fix the night, not just the morning

If you go to bed at 1 a.m. and wake at 7, no trick will hold for long. For many people, the phone is what pushes bedtime later. Blocking the apps that keep you scrolling after a set hour often does more than any alarm; here is how to block apps on iPhone, and why reaching for your phone first thing in the morning makes the start of the day harder.

Where Up fits

Up is an anti-snooze alarm for iPhone (iOS 26 or later) that combines fixes 3, 5 and 7 in one app. The alarm runs on AlarmKit, Apple’s alarm framework, so it rings like the built-in Clock app, even in Silent mode or a Focus. It only stops once you complete a mission: 5 mental math problems, 3 color sequences to memorize and repeat, 3 spoken words to recognize by ear, or one of the three at random.

Two safeguards target falling back asleep: if you stall on the mission, the alarm starts ringing again, and an optional “Still awake?” check comes back a few minutes later. Up can also block the apps you choose for a set time right after you turn the alarm off (30 minutes, for example), and in the evening on a schedule you choose, using Apple’s Screen Time API. Up is free to download, with a subscription and a free trial.

What Up won’t do: replace a reasonable bedtime. If you sleep five hours, the mission will get you up, not rested.

Should you quit snoozing completely?

Not necessarily. If you hit snooze once, for ten minutes, and feel fine by mid-morning, the current research gives you no reason to stop. If you snooze every day for 20 minutes or more and still get up late and foggy, it is costing you solid sleep and your first decision of the day. Pick one fix and run it for two weeks; setting the alarm for your real wake time is the easiest and has the best effort-to-result ratio.

If your problem is that you don’t hear the alarm at all, read our guide on how to wake up as a heavy sleeper.

Tomorrow morning, you get up.

Up is an anti-snooze alarm that rings through Silent mode and only stops once you’ve solved a mission, plus app blocks that keep your feeds closed until you’re started.

Frequently asked questions

Is hitting snooze bad for you?

Not in any dangerous way, based on current research. In a Stockholm lab study of 31 habitual snoozers, 30 minutes of snoozing did not worsen mood, cortisol or cognitive performance (Sundelin et al., 2023). A smaller Japanese study of 10 students did find longer grogginess after snoozing (Ogawa et al., 2022). The clear cost is broken sleep instead of solid sleep.

Why do I keep hitting snooze?

Usually because you are tired. In a survey of 1,732 adults, the most common reason for snoozing was feeling too tired to get up, and snoozers were younger, more often night owls and slept slightly less (Sundelin et al., 2023). An alarm set earlier than you need to rise also invites snoozing.

Does snoozing make you more tired?

It can, but not always. A 10-person lab study found snoozing in the last 20 minutes of sleep prolonged sleep inertia and slowed reaction times (Ogawa et al., 2022). A 31-person study found 30 minutes of snoozing left people as sharp or slightly sharper right after getting up (Sundelin et al., 2023). If you feel worse after snoozing, trust that.

How long is snooze on iPhone?

For years, iPhone snooze was fixed at 9 minutes. Since iOS 26, the Clock app lets you pick a snooze length between 1 and 15 minutes for each alarm. You can also switch the Snooze toggle off entirely so the button no longer appears when the alarm rings.

Do mission alarm apps actually work?

They remove the reflex: you cannot silence the alarm half-asleep, you have to solve a math problem or a memory task first. No published study has measured their effect on grogginess yet, so the benefit is practical rather than proven. By the time the mission is done, you are sitting up and awake enough to decide.
