You snooze, you lose: Why killing the morning alarm is not very good for your sleep
A global study suggests that killing the snooze button disrupts the significant REM sleep stages. Experts warned that this habit could lead to the quality of sleep and poor sleep.

In short
- Heavy snoozers get 20 additional minutes of fragmented light sleep
- The most common snoozing on workday
- Experts recommend setting alarm for the latest time and avoid snooze
Most of us have done this: hit the snooze button to steal a few more minutes.
But when it can feel like a harmless habit, a new study led by Researchers of Mass General Brigham (the largest hospital-based research firm in the US) suggests that it cannot give any favor to our sleep health.
The study published in scientific reports analyzed more than 3 million nights using the Sleep Cycle App data.
It consisted of over 21,000 people around the world and found that about 56% of the sleep sessions ended with killing someone’s snooze button.
On average, the snousers delayed getting out of bed for about 11 minutes.
Heavy users of the snooze alarm (which was studied more than 80% of the morning, the snooze alarm rely on the alarm) spent an average between the snooz alarm in 20 minutes.

Heavy snooze alarm users also showed more uncertain sleep schedules than other categories of users.
Snoozing is common but not ideal
In the global sample, researchers found that more than half of the sleep sessions finish in a snooze alarm, and users spent an average of 11 minutes on an average between snooze alarm every morning before waking up.
“Many of us hit the snooze alarm in the morning with a little more sleep,” the study’s lead writer and Brigham and a sleep specialist at the Women’s Hospital. Rebecca Robins said.
“But this extra sleep is usually very light and fragmented,” Robins said.
In fact, he explained that the final stages of sleep are important before waking up naturally.
This occurs when our brain gets rich amounts of REM sleep, which is important for memory and emotional processing.
Robins said, “The hours before waking up the rapid eye movement are rich in sleep.

Repeatedly interrupted with alarm can make us feel growth rather than being refreshed.
When and where we snoo the most
The study also found that snoozing is the most popular during the work week, especially from Monday to Friday. People do less snooze on weekends, perhaps because they are more naturally awake or sleeping.
Interestingly, people who slept less than five hours were less likely to have snooze, possibly because they had to get up immediately due to work or other responsibilities.

In terms of geography, snoozing was the highest in the US, Sweden and Germany, and the lowest in Japan and Australia.
What is the fix?
Although it can be attractive to suppress the button, sleep experts recommend resisting the urge.
Robins said, “The best way to optimize your sleep and the next day is to set your alarm for the latest possible time, then when your first alarm is closed, it is committed to get out of bed.”
Sticking to the schedule of a consistent sleeping sleep, going to bed first, and creating a cool morning routine can also help reduce many alarm needs.
So, next time you feel like snoozing, remember, they are not making your body or brain no good.
