And being jolted awake at this time can cause sleep inertia and grogginess that can last for up to four hours. But, when you hit the snooze button and go back to sleep, the next time you are woken by your alarm (usually just nine minutes later!) you are only at the start of a sleep cycle. If you are woken towards the end of your sleep cycle, like when your alarm first goes off in the morning, your sleep inertia tends to last for up to 30 minutes as your brain adjusts to the waking-up process. What’s more, recent research has shown that hitting the snooze button can extend the period of grogginess -called sleep inertia - we feel upon first waking. Not getting this quality sleep can have consequences to our physical and mental health. This REM sleep is really important for our brains to properly rest and form new memories. Leaders in this science say we go through sleep cycles that last around 45 minutes and if you’re snoozing for additional periods of just nine or ten minutes at a time, you will never get back into any meaningful rest. Unfortunately, hitting that snooze button might be leaving you more tired than you think.

Studies show that snoozing before we get up for the day is pretty standard practice, with more than half of people ages 25-34 hitting snooze daily. If you’re anything like us, those precious extra minutes of snoozing in the morning seem like no brainer! And how is it that you are never more comfortable than when that alarm goes off?!
