![]() ![]() “If you are constantly falling back asleep after your alarm clock goes off, the clock can become a confusing signal for wakefulness.” -Dr. Which is to say, you might struggle even more with actually waking up on time when you need to, and you could find it easier to oversleep on subsequent nights, she says. “If you are constantly falling back asleep after your alarm clock goes off, the clock can become a confusing signal for wakefulness,” says Dr. And again, because those deeper sleep stages are lengthier and more common in the hours just before you get out of bed, you’re all the more likely to fall back into one of those phases post-snooze and have that much more trouble shaking off the sleepiness when your alarm rings once again.Īside from this potential heart impact, the effects of snoozing can also put a wrench in your sleep routine the more often you do it. That’s because sleep inertia-which is that drowsy just-woke-up feeling- sticks around longer when you wake up from a deeper sleep stage, like REM sleep, than it does when you wake up from a light sleep stage, says Dr. “This sleep fragmentation can leave you feeling worse than you would have if you hadn’t interrupted your sleep cycle with the snooze button in the first place.” “We experience more REM sleep as we approach the morning-meaning that if you snooze, you’re likely to fall back into a REM cycle but won’t have time to complete it before your alarm goes off again,” she says. “Sleep fragmentation can leave you feeling worse than you would have if you hadn’t interrupted your sleep cycle with the snooze button in the first place.” -Angela Holliday-Bell, MD, sleep physicianĪnd the second (and third and fourth…) time you wake up post-snoozing may be even tougher than the first, given that you’re more likely to be waking yourself up in the beginning or middle of a REM cycle, says Dr. The problem with snoozing, though, is that it puts your body through the ringer of awakening in this high-stress fashion not just once but multiple times. While this is not the best way to wake up (that would be waking up naturally or with a gentle no-sound alarm clock), the demands of life might require you to wake up this way, particularly if you have to be awake at a time that doesn’t align with your natural sleep chronotype. Grade school is the snooze button on the clock-radio of life.The real-time negative effects of snoozing your alarmĪny noise-based alarm tends to activate your sympathetic nervous system: the fight-or-flight response that jolts you awake with a release of cortisol, which temporarily elevates your heart rate and blood pressure. You're dehydrated Up to 60 percent of the adult human body is water, and water helps regulate body temperature.ĭeath is much like an alarm clock except there is never a snooze button to give you just a moment more, before you really have to wake. When you're fatigued from a restless night, your metabolism works at a more sluggish pace, Holly Phillips said, producing less heat and slower circulation. Metabolism may be a culprit here as well. A study from the European Journal of Applied Physiology appears to back this up : researchers documented a drop in body temperature in 20 sleep-deprived young adults. ![]() It's not clear why this happens studies suggest that in response to the stress of not getting quality snooze time, there's a reduction in activity in the hypothalamus, the control panel of the brain where body temperature is regulated. They say all the right things but they never do the right thing. It sounds negative and cynical, but it's true. This incident is a recurrence of past incidents, every time event planners and promoters get a wake up call, they hit the snooze button. If you need to rise first, offer to not hit the snooze button too often, so it goes off a bunch of times and disturbs the other person. ![]()
