Don’t forget to change your clocks.

If you noticed you had an easier time getting out of bed this morning, you have Mother Nature to thank.

As of 2 a.m. on Sunday, November 4, daylight saving time officially ended. The clocks fell back an hour, meaning sunrise and sunset times will be an hour earlier.

The good news — for now, at least — is that most people struggle more with losing an hour of sleep in the spring.

The bad news? Many of us are going to have a harder time falling asleep the next few days as we adjust our schedules to the time change.

Daylight saving time
throws off your body clock

The reason the start and end of daylight saving time can throw us for such a loop boils down to our circadian rhythm — an internal clock that manages our sleep-wake cycle.

Your circadian rhythm is the reason you may feel alert in the morning, groggy in the afternoon, and zonked by bedtime.

It works best when you have a set routine and stable sleep habits. When your circadian rhythm is thrown out of whack, as it is with daylight saving time, sleep disruptions are likely to occur.

Research has shown time and time again that sleep protects us from physical and mental harm.

Without sleep, we’re more prone to craving unhealthy, high-calorie foods, and we’re less likely to exercise. This combination can cause you to feel more irritable and less productive. Not to mention, the more sleep-deprived you are, the more likely you are to get sick.

“It’s important not to underestimate the importance of sleep, especially with the time change marking the end of daylight saving time,” Dr. Jose Puangco, a neurologist specializing in sleep medicine at the Pickup Family Neurosciences Institute at Hoag Hospital in Newport Beach, told Healthline.

“The time change can disrupt your circadian rhythm, and the brain needs a little prep time to get used to this new schedule,” he added.

1. Avoid electronics
before going to bed

Turn off all electronics an hour before bedtime, Puangco recommended. Resist the urge to check your email, watch Netflix, or read your Kindle, as these activities can keep you feeling alert and stimulated.

“Light from TVs, computers, tablets, and cellphones can suppress melatonin and affect the quality of your sleep,” Puangco said.

Absolutely need to send out that email before you hit the sack? Try dimming the display light on your phone or computer.

Electric devices emit tons of blue light, which tricks your brain into thinking it’s daytime. If you often have to work at night, purchase a pair of blue-blocking glasses or install an app like f.lux, which automatically adjusts the color and brightness of your screen based on your current time zone.

2. Don’t overdo it
with the caffeine

Many of us depend on our morning cup of coffee to help get our days going — and there’s nothing wrong with that. But if you’re constantly refilling your mug throughout the day, you may want to cut back.

“Avoid any caffeine after lunchtime,” Puangco said. “The effects of caffeine can linger for many hours after being consumed and can hinder you from sleep.”

In fact, even if you drink caffeine six hours before bedtime, you’re still likely to lose a full hour of sleep, according to a study published in the Journal of Clinical Sleep Medicine.

3. Ease into the time
change

Many people struggle with falling asleep an hour earlier when the clocks fall back. Counting sheep can only do so much.

Some health experts recommend gradually easing into the time change.

“Slowly shift your bedtime by 15 minutes each night. This will allow your body to naturally adjust when the clocks turn back,” Dr. Beth Donaldson, a family physician at Copeman Healthcare Centres in Vancouver, said.

For example, maybe tonight you go to bed 15 minutes earlier, and then tomorrow night you aim for 30 minutes earlier. Within a week or so, you should be back on track.

4. Stick to a set sleep
schedule

Once you’ve eased into it, make a point to go to bed and wake up at the same time every day — even on the weekends. This will help your body regulate its sleep cycle.

Additionally, just because you’re getting an hour back doesn’t mean you should stay up later and fill the time with extra activities.

Significantly switching up your sleep patterns increases your risk of being affected by the daylight saving time change, Donaldson explained.

5. Nap if you need to

If you begin to feel sleep-deprived, a nap may be in order.

“If you feel sleepy in the afternoon, take a nap, but avoid sleeping in in the mornings as this will only prolong your body’s reaction to the time change,” Donaldson said.

However, don’t nap too close to bedtime — as this can interrupt your sleep overnight — and try to keep your naps to 30 minutes or less.

All in all, don’t be alarmed if you catch yourself feeling out of sorts this week.

Daylight saving transitions can throw off your body’s circadian rhythm. Your body clock will eventually adjust to the time change — it may just need a little TLC to get there.
