It's 7:00 AM. Your alarm goes off. It’s loud, jarring, and honestly, it feels like a personal attack. You reach out, eyes half-shut, and fumble for that one specific button. Snooze. You get nine more minutes of bliss. Or so you think.
But what does snooze mean for your brain? Most of us treat it like a mini-vacation, but biologically, it’s more like a glitch in the system. When you hit snooze, you aren't actually getting "more sleep." You're just putting your internal clock through a blender.
The Science of Why Nine Minutes Feels Like Nine Seconds
Have you ever wondered why the snooze interval is almost always nine minutes? It’s not an arbitrary number pulled out of thin air by Apple or Samsung. Back when mechanical clocks were the standard, engineers had to interface the snooze lever with the existing gear train. Nine minutes was the longest interval they could manage without redesigning the whole clock face. It stuck.
When your alarm blares, your body is usually in the process of "lightening" its sleep. Your core temperature rises. Your brain starts pumping out cortisol to get you moving. By hitting snooze, you tell your brain, "Wait, just kidding, go back to sleep."
The problem? You might fall back into a deeper state of sleep, like REM (Rapid Eye Movement). When the alarm goes off the second or third time, it catches you in the middle of a sleep cycle. This creates a state known as sleep inertia.
Sleep inertia is that heavy, "hit by a truck" feeling that lingers for hours. You’ve probably felt it. You woke up at 7:00 AM feeling okay, but by the time you actually got out of bed at 7:30 AM after three snoozes, you felt like a zombie. That’s because you interrupted a new sleep cycle that your brain started but couldn't finish.
Social Media and the Virtual Snooze
"Snooze" isn't just about bedsheets and alarm clocks anymore. In the digital world, the word has taken on a life of its own. On platforms like Facebook or Instagram, "snoozing" a person or a group means you’re muting them for 30 days. It’s a polite way of saying, "I can’t deal with your political rants right now, but I don’t want to go through the drama of unfriending you."
It’s a temporary boundary.
Technology has hijacked the term because the metaphor works so well. It’s a pause button. Whether it’s your annoying uncle’s posts or your morning responsibilities, snoozing is a tool for avoidance. It feels good in the moment, but the underlying issue—the lack of sleep or the annoying relative—is still there waiting for you when the timer runs out.
Is Snoozing Actually Bad for You?
The short answer is yes. But it’s complicated.
Dr. Reut Gruber, a researcher at McGill University, has often pointed out that if you need to snooze, you’re likely sleep-deprived to begin with. The snooze button is a symptom, not just a habit. If you were getting the 7–9 hours of quality sleep your body requires, you wouldn't feel the desperate urge to cling to those extra nine minutes.
When you fragment your sleep, you lose out on the restorative benefits of a full, uninterrupted cycle. Think of it like a computer update. If you keep hitting "remind me later," the software never fully optimizes. Your brain's "cleaning system"—the glymphatic system—needs consistent time to flush out toxins. Interrupting that process with five-minute bursts of sleep is essentially useless.

Interestingly, some people swear by the "pre-wake" snooze. They set an alarm 20 minutes early just so they can hit snooze twice and "wake up gradually."
Psychologically, they feel more in control.
Biologically? They’re just losing 20 minutes of deep, high-quality sleep they could have had if they just set the alarm for the time they actually needed to get up.
The Pavlovian Trap
We are training ourselves to ignore alarms. This is the part people rarely talk about. If the sound of your alarm doesn't mean "get up," then what does it mean? It becomes background noise. Over time, your brain learns that the first three alarms are suggestions, not commands.
This can lead to some pretty stressful situations.

I once knew a guy who had 15 different alarms set at two-minute intervals. By the time he actually stood up, his heart rate was through the roof, and he was already in a state of "fight or flight." That’s a terrible way to start a day.
How to Stop the Cycle
Breaking the snooze habit is brutal for the first few days. Your body will fight you. But there are ways to make it easier that don't involve throwing your phone across the room.
- The 5-Second Rule: Popularized by Mel Robbins, the idea is to count down 5-4-3-2-1 and physically launch yourself out of bed before your brain has a chance to talk you out of it. It sounds silly. It works.
- Light Exposure: Your brain stops producing melatonin (the sleep hormone) when light hits your eyes. Open the curtains immediately or use a sunrise alarm clock that mimics the sun.
- The Phone-in-the-Hallway Trick: If you have to physically walk 10 steps to turn off the noise, you’re much less likely to crawl back under the covers.
- Adjust Your Bedtime: If you're hitting snooze every day, you are telling yourself you didn't sleep enough. Listen. Go to bed 30 minutes earlier tonight.
What Snooze Really Tells Us
At the end of the day, "snooze" is a bridge between the dream world and reality. We use it because transitions are hard. We use it because we’re tired. We use it because we want to feel a sense of agency over our time, even if it's just for nine minutes.
But if you want to wake up feeling refreshed, you have to respect the boundary between sleep and wakefulness. Stop the fragmentation. Set your alarm for the latest possible time you can get up, and then actually get up.
Your brain will thank you by the time your second cup of coffee hits.
Actionable Next Steps
- Check your phone's screen time: See if late-night scrolling is the reason you're reaching for the snooze button in the morning.
- Move your alarm: Tonight, place your phone or clock on the other side of the bedroom.
- Invest in a sunrise lamp: These devices use light to wake you up naturally, reducing the "shock" of a loud alarm and making the snooze button less tempting.
- Consistency is king: Wake up at the same time even on weekends to regulate your circadian rhythm and eventually eliminate the need for an alarm altogether.
