When the alarm goes off at 7am, it's hard not to roll over and tap the snooze button on your phone. As tempting as it is to try and sneak in a few extra minutes of sleep, the habit of hitting snooze may actually be worse for you in the long-run.
According to Dan Ariely, a behavioral scientist who writes for the Wall Street Journal, hitting snooze can seriously disrupt your entire day.
The sound of your alarm clock, he explained, should be a sort of conditioning tool. When the alarm clock goes off, it should signify to your body that it's time to get out of bed. Hitting snooze disrupts this conditioning. "In general, our bodies do better when they can get used to a single clear rule: Get out of bed the moment the alarm sounds," he explains.
The second or even third alarm that sounds when you hit snooze confuses your body. If you wake up on the first alarm, you learn to associate the sound of the alarm with getting out of bed, and over time, it becomes easier and easier to wake up. Hitting snooze throws off that routine, making mornings a total drag.
It's not only the Pavlovian response that makes waking up on the first alarm with it--hitting snooze can actually make you more groggy than if you'd just gotten up with the initial alarm.
When you let yourself go back to sleep--even for a few minutes-- both your body and your brain are surprised. The more times you hit snooze, the more confused you get, resulting in a fuzzy-headed feeling called sleep inertia. According to Rafael Pelayo, MD, a sleep specialist at the Stanford University Sleep Medicine Center, this type of sleep inertia can last for two to four hours after you actually wake up, totally throwing off the track of your entire day.
The bottom line is that it's better for your body and your mind to just get up at the same time--and with the first alarm--every morning.
