The Science Behind the Snooze

Love a good snooze? Well, you’re not alone, many of us admit to hitting the snooze button at least once in the mornings. Although pretty darn good at the time, it turns out that these glorious few minutes may actually have a severe impact not just on the way we feel in the morning but for the rest of the day too….

 According to ASAP science, in the last 1-2 hours of sleep, the body kick-starts its biological mechanisms to wake you up. Your body temperature increases, sleep becomes lighter and energy hormones such as dopamine and cortisol are released. Using an alarm interrupts this natural sleep cycle and cuts short the waking up process, leaving us with that well-known groggy feeling called ‘Sleep-inertia’. 



Hitting the snooze button means the body is tricked into thinking it is going back to sleep and re-enters the sleep cycle.  

When the buzzing goes off 5-10 minutes later, you could actually be in a deeper stage of sleep than you were originally, therefore increasing the sleep inertia. The more you snooze, the more confused your body gets and ultimately, the worse you feel. 

Doesn’t sound great does it!

 So, what’s the best way to prevent all this? ASAP recommend setting your alarm later and getting up when the alarm goes off (we think this could be a little easier said than done)

Making a routine can also work wonders, this involves going to bed and waking up at the same time each day (including the weekends…!) After 2 weeks, it is said that your body will have readjusted its internal clock meaning you may be able to scrap the alarm altogether. We’re sold.
