Experts say that hitting snooze can fragment your sleep.
  • A 2022 sleep study found that 57% of participants hit the snooze button regularly.
  • A neuroscientist explains how hitting the snooze button can fragment your last minutes of sleep.
  • She also explains how then being late can raise your cortisol levels and make you more stressed.

At 6:45 a.m., your first alarm goes off, and you press the snooze button. 6:54 a.m., your second alarm goes off, and again, you hit snooze. Then again, every nine minutes until you realize you can't press the snooze button anymore or you'll be late for work.
