Don’t let the end of daylight saving time disrupt your sleep

Most people worry about losing an hour of sleep when daylight saving time (DST) begins in the spring, but its end can completely throw off your daily schedule and overall mood. “Falling back” this November and gaining an extra hour may sound amazing, but you might not realize it can actually be quite taxing on your body. Luckily, there are ways to keep the changing daylight hours from throwing you off your sleep routine.

Do we lose an hour or gain an hour?

One of the biggest misconceptions about winding the clocks back an hour the first Sunday in November is that you get more sleep. But according to Anthony Komaroff, M.D., that’s not always the case. “In reality, many people don’t, or can’t take advantage of this weekend’s extra hour of sleep. And the resulting shift in the body’s daily sleep-wake cycle can disrupt sleep for several days.”1 He goes on to say that only a small number of people actually get an hour of extra sleep and “during the following week, many people wake up earlier, have more trouble falling asleep, and are more likely to wake up during the night.”

Light and the circadian rhythm

What’s that rhythm thing, you ask? Your circadian rhythm is your internal clock that cycles between sleepiness and alertness at regular intervals throughout the day.

It’s no secret that you sleep better when the sun is down and the lights are off. That’s because “light exposure at night also stimulates alertness – and that can pose a serious problem for healthy, abundant, refreshing sleep.”2 That can also result in your circadian rhythm getting out of whack. As your internal clock is influenced by sunlight and temperature, keeping a schedule that is aligned with the sun is key to sustaining a regular sleeping routine.

On the other hand, bright light exposure throughout the day can make your sleep at night feel deeper and more satisfying.3 It’s all about balance.

Three sleep tips for fall daylight saving

Setting the clocks back an hour can mess up your sleep schedule and circadian rhythm, but it doesn’t have to. Here are a few tips to help you adjust accordingly and get a good night sleep:

  • Briefly adjust your times. If you’re lucky enough to work a semi-flexible schedule, try zonking out and waking up 15 minutes later for the first couple of days of the transition. And if you’re really flexible, sneak in a 30-minute to an hour cat nap.
  • Don’t stay up too late. It may be tempting to squeeze in one more hour-long episode of your favorite show, but don’t do it. According to Dr. Illene Rosen who serves on the board of the American Academy of Sleep Medicine (AASM), “One of the biggest mistakes that people make… is staying up later and thinking that they’re going to get an extra hour of sleep.” That internal clock of yours is likely to wake you up early that Sunday so don’t count on an extra hour.
  • Rely on the sun. The sun can be your friend in terms of getting good sleep at night. According to Dr. Rosen, the time change in the fall is far easier to adjust to than the one in the spring. She suggests, “Try to get as much late afternoon sun exposure before switching the clocks back, and as much morning sun as possible after switching the clocks to help ease the transition.”
