It's 6:30 am, your alarm is rings you drowsily stretch out, eyes half-closed, and press the snooze button. Nine minutes later, that same chime is ringing again. You silence it once more. Another nine minutes. Does this sound familiar?If so, you’re not alone. In fact, you’re part of what sleep researchers are calling a global “snooze epidemic.” According to a landmark study conducted by Mass General Brigham, more than 55% of people worldwide engage in snoozing behavior regularly often multiple times each morning. But while this habit may feel harmless or even comforting it could be quietly wreaking havoc on your mental sharpness, emotional well-being, and even long-term health.Why We Love to Snooze? The Psychology of 'Just 5 More Minutes'There's a comfort in the belief that it's possible to delay reality by a few more minutes. That brief space between sleep and the exigencies of the day can feel like a shield. But what our brain reads as comfort is actually confusion."That fragmented sleep you’re getting between alarms is not restorative," says Dr. Rebecca Robbins, a sleep scientist at Brigham and Women’s Hospital. "In fact, you’re disrupting one of the most important parts of your sleep cycle REM sleep which helps regulate memory, mood, and learning."In the Mass General Brigham study, in which it examined data from more than 3 million sleep sessions tracked through wearable devices, heavy sleepers were averaging 2.4 snoozes in the morning for a total of almost 11 minutes. For others, there's more. Roughly 45% of users were snoozing over 80% of the time, adding almost 20 extra minutes in bed after their alarm.That may not seem like a big thing. But what's going on in your brain during that time is bigger than we realize.What Happens in Your Brain When You Hit Snooze?Our sleep consists of cycles—alternating between light sleep, deep sleep (NREM), and rapid eye movement (REM) sleep. REM is the most active stage in which the brain is working hardest, processing emotions and locking in memories. This stage usually gets the majority of our sleep cycle going in the last few hours before we wake up."When you hit the snooze button and sleep through it, you're fooling your brain into starting a new cycle it can't finish," says Dr. Robbins. "And then, when you wake up to an alarm just minutes later, you're waking up from a sleep cycle your brain wasn't done with yet."The outcome? Sleep inertia—a lingering feeling of groggy sleepiness, brain fog, and even irritability that can last hours.Why Snoozing Is More Than Just a Morning Quirk?Though snoozing appears to be a harmless morning luxury, sleep specialists caution that it might have wider health consequences. Continuously disturbing sleep—even for a short few minutes—is capable of causing cumulative sleep fragmentation that is associated with:Decreased cognitive functioningMore stress and irritabilityCompromised immune functionChronic sleep disorder riskGreater likelihood of depression and anxietyWhat's more, many chronic snoozers end up developing what's called "social jet lag"—a perpetual mismatch between their internal clock and their social schedule, which can influence metabolism, cardiovascular health, and hormone regulation in the long run.How to End the Snooze Habit?Experts recommend a change of mindset—and some creative redesigning of your environment to make it simpler:Rethink Your Alarm Strategy: Employ a waking light or sounds of nature rather than jarring sounds that activate stress.Place Your Alarm Out of Reach: Make yourself leave the bed to silence it.Stick to a Sleep Schedule: Retire and rise at the same time every day—even weekends.Improve Sleep Hygiene: Stay away from screens one hour prior to bedtime, and make the sleeping area dark, cool, quiet.Wake Yourself Up in the Morning: Create an intention, reward, or morning routine that you anticipate.Eventually, waking should be a natural step not a fight. Snoozing can provide temporary relief, but consistently good sleep and a better morning begins the night before.
