How you start your morning can set the tone for the rest of the day. A screaming match with your partner? Not a good way to start. A good, hearty breakfast? Much better. But your day could just as easily be derailed by other, more seemingly innocuous habits. How many of these do you do?

Hitting the Snooze Button

“Hitting the snooze button is frequently a sign that you are not getting enough sleep,” says Robert Rosenberg, M.D., Medical Director of the Sleep Disorders Center of Prescott Valley, Arizona and author of Sleep Soundly Every Night, Feel Fantastic Every Day. “But it may also be a sign of ‘social jet lag,’ a condition where you are staying up too late on weekends and then because of the sleep debt you have built up, you need more sleep on work days.” When you hit snooze, you disrupt your sleep cycles and you end up sleepier than if you had gotten up in the first place. You also scramble your internal circadian clock, which tells you when to sleep and when to wake, Dr. Rosenberg says. This makes it even harder to get up when your alarm rings.

And speaking of alarms, no studies have proven them to be detrimental, but Dr. Rosenberg adds, “It probably sends your stress hormone soaring and triggers your fight or flight response. I would think that if you have high blood pressure or heart disease, or suffer from an anxiety disorder, this is not a good idea.”
