Why You Might Want To Change Your Alarm Clock In The New Year

"The consistency of your sleep schedule is actually what gives you energy," Michael Breus, Ph.D., a clinical psychologist, once explained on an episode of the mindbodygreen podcast. According to the board-certified sleep specialist, if you can find a wake-up time that matches your body's inherent sleep pattern (also known as your sleep chronotype), "you will have far more energy and—believe it or not—need less sleep."

Over time, your body should get used to waking up at this time and do so naturally—no ocean waves or "Here Comes the Sun" chorus needed. But if you're not quite there yet, alarm clocks can help keep you on track. They do have a downfall, however, and that's the snooze button.

Comforting as those nine extra minutes of shut-eye may be, they don't allow enough time for you to actually slip into the deeper stages of sleep, where real repair and restoration can occur. And by repetitively jolting you out of your slumber, snoozing can also cause you to feel even groggier when you finally do get out of bed.

"Nobody wins," holistic psychiatrist Ellen Vora, M.D., previously told mbg of the downfalls of snoozing. "You're not getting great rest, and you're also not having a leisurely, relaxed morning." 

To find the best alarm for you, you'll need to consider your personal sleep habits. If you always press the snooze button, an old-fashioned clock that doesn't have one might be for you. If you often sleep through your alarm, an extra-loud clock designed for heavy sleepers could be the ticket.

As for what experts use on their own nightstands, alarm clocks that gradually get brighter to simulate the sunrise are becoming increasingly popular. It makes sense that these are beloved by sleep specialists, given that there's real science backing them up. Exposing yourself to bright light first thing in the morning—and throughout your entire day—has been shown to help keep your circadian rhythm on track (and, by extension, keep your sleep-wake cycle more consistent).

Nishi Bhopal, M.D., a psychiatrist specializing in sleep medicine, says that the Philips light she uses helps her wake up feeling more alert. "It just kind of eases you into a state of wakefulness," she tells mbg. "It's much less jarring than an old-fashioned alarm clock, or even an alarm on your phone."

If you've ever heard of people using sun lamps to adjust to seasonal changes in light, these alarms work similarly. By mimicking the light of the sun in the morning, they send a clear signal to the body that it's time to wake up and get going. "Early morning exposure to bright light stimulates photoreceptors in our retinas, shutting down melatonin levels and allowing cortisol to rise," immunologist Heather Moday, M.D., previously explained to mbg. "It also increases the production of serotonin—one of our feel-good hormones."
