I've read that the
snooze button really, really interferes with the wake-up process of the brain. To caricature, in my understanding snoozing the alarm clock can render you a zombie for at least part of the day.
"But what you’re actually doing is making the wake-up process more difficult and drawn out. If you manage to drift off again, you are likely plunging your brain back into the beginning of the sleep cycle, which is the worst point to be woken up—and the harder we feel it is for us to wake up, the worse we think we’ve slept."
So how bad is our beloved snooze button? Is
snooze indeed that damaging for daily productivity?
