Have you ever wondered why the snooze time on iPhones is 9 minutes, not 5 minutes or 10 minutes?
If you are an iPhone user, you may be too familiar with the haunting alarm clock that makes anyone's heart skip a beat every morning. In case you don't want to get out of bed, you can also choose the "snooze" function to postpone the alarm time and sleep for another 9 minutes.

The default snooze time on iPhone is 9 minutes.
However, have you ever wondered why this snooze time is 9 minutes, not 5 minutes or 10 minutes?
In fact, this 9-minute snooze time is not an idea or invention of Apple. According to iDropNews, the "snooze" button was first designed by clock engineers in 1956 and the snooze time also lasted 9 minutes. Of course, this is not a coincidence.
Initially, clock engineers wanted to set the snooze time to 10 minutes. However, setting the gears on the clock to achieve the exact 10-minute time was almost impossible. Therefore, they chose the 9-minute setting solution.
In addition to the technical factors, 9 minutes is also considered the perfect time for the snooze time setting.
Accordingly, 9 minutes is just enough time for a short nap. Meanwhile, if you sleep for more than 10 minutes, your body will begin to fall into a deep sleep. This will make it more difficult to wake up and cause discomfort to the body.
"Apple has chosen a 9-minute snooze time based on the sleep cycle, which is beneficial to the health of users. However, you should not abuse this feature," said Holly Schiff, a psychologist.

Sleeping after the first alarm can make your body more tired.
According to iDropNews, using the snooze feature every morning is not a good habit because it can disrupt and disrupt your biological clock. You think that sleeping for an extra 9 minutes will help your body feel less tired throughout the day, but in fact, it can be completely the opposite.
When you decide to press the snooze button, your body will gradually fall back to sleep, only to be woken up again immediately after. This can make you feel sleepier than waking up right from the first alarm.
