Why Hitting the Snooze Button Makes You Sleepier
In Why Hitting the Snooze Button Makes You Sleepier, host Harith Iskander explains what happens when we hit the snooze button in the morning. Science shows that the body starts preparing to wake up when the alarm rings, but pressing snooze resets the body’s sleep cycle. This causes the body to go back to the beginning of the cycle, making you feel even sleepier. This video is excerpted from BBC’s Got Science?, a science magazine series that explores and explains science in everyday life.
Lesson Express
Q: Why does hitting the snooze button make you feel sleepier?
A: Pressing snooze interrupts the body’s natural wake-up process, causing it to return to the beginning of the sleep cycle, which makes you feel groggy.
Q: What does the body do when the alarm rings in the morning?
