Hitting the snooze button actually has benefits. About 69-percent of people hit the snooze button at least “sometimes,” according to the “Journal of Sleep Research.” So what are the benefits? If you are a night owl, it helps to slap the button because you wake up with better cognitive ability, and less grogginess. The downside is you’re still grumpy. That 10 extra minutes of sleep actually is a light sleep stage and that’s the key to the benefit.
