  • The snooze button, one of man's best inventions...until nine minutes later when

  • the dreaded alarm strikes again. Except now you feel even more tired, so do you

  • hit it again? Are those extra minutes really helping at all? Or is it the

  • beginning of a never-ending cycle that ends in you being late and still dead tired.

  • In an unimaginable world without alarm clocks our bodies would simply wake up

  • naturally, seems crazy right? But our bodies have many chemical mechanisms in

  • place to not only put us to sleep, but wake us up as well. The body begins

  • preparing in the hour before you naturally wake-up, body temperature rises

  • sleep becomes lighter and hormones such as dopamine and cortisol are released

  • which give you energy to start your day. But the problem with alarms is that they

  • often interrupt your sleep cycle and cut these processes short. Particularly if you

  • don't have a regular sleep rhythm or schedule, the alarm goes off, but your body

  • isn't quite ready. This groggy and tired state is known as "sleep inertia"

  • and its strength is related to which sleep stage you are waking up out of.

  • The deeper the sleep the more potent the sleep inertia and so the snoozing

  • begins. But the snooze button can do more damage than good, as you fall back asleep

  • the body be restart its sleep cycle and enter into deeper sleep stages. So

  • instead of your body prepping to wake up, it's going in the opposite direction and

  • as a result the second alarm may cause you to feel even more tired

  • and so continues the vicious cycle.

  • Ultimately. you would be better off setting your original alarm later and not

  • interrupting your sleep. Many studies have found that fragmented sleep is much

  • less restorative

  • and leads to sleepiness related daytime impairment. So by breaking up those last

  • thirty minutes or so of sleep, you are more likely to feel tired and perform

  • poorly during the day. What else can you do? Try adopting a more regular sleep

  • schedule. Being tired is not only a product of sleep deprivation or waking

  • up out of a deep sleep, but also lacking a consistent schedule. The body loves

  • predictability, wake up at the same time every morning, including the weekends, and

  • after a few weeks your body should adapt to the timing and be less inclined to

  • require an alarm in the first place. And if you do wake up feeling a little

  • tired, try to resist the snooze temptation and just get up,

  • because as the saying goes "you snooze you lose".
