How to Reset Your Sleep Before the Clocks Fall Back on Nov. 1

Picture a parent in a Park Slope walk-up whose toddler wakes at 6 a.m. sharp, every day, no matter what. On Sunday, Nov. 1, the clocks fall back an hour, and that 6 a.m. wake-up suddenly reads 5 a.m. on the microwave.

For a lot of New Yorkers, the “extra hour” of sleep never shows up. Kids, early risers and anyone already short on rest can spend the following week groggy at work and wide awake before dawn.

It does not have to go that way. Sleep medicine experts have a simple playbook, and the best time to start it is now.

When do the clocks fall back in 2026?

Daylight saving time ends on Sunday, Nov. 1, 2026, at 2 a.m. local time, according to the National Institute of Standards and Technology. At that moment, clocks move back to 1 a.m., and the hour repeats.

Phones and computers update on their own. Ovens, microwaves, car dashboards and wall clocks usually do not, which is why so many households spend Sunday morning arguing about what time it really is.

The bigger shift happens inside your body. Your internal clock does not read the microwave.

Why does a one-hour change throw off your sleep?

Your sleep and wake cycle runs on a roughly 24-hour internal clock, the circadian rhythm. The American Academy of Sleep Medicine (AASM) calls light and darkness the most powerful timing cues for when we feel alert and when we feel sleepy.

When the clock jumps back, your body is still running on the old schedule. In practice, that means:

• You may wake up an hour earlier than you want, by the new clock.
• You may feel sleepy earlier in the evening.
• Meal times and hunger can feel out of sync for a few days.

The AASM says seasonal time changes can disrupt sleep schedules and hurt sleep quality, and that they can be especially hard on people who already sleep too little, including teenagers and night shift workers.

Is the fall time change bad for your health?

The fall change is generally considered gentler than the spring one, because you gain an hour instead of losing it. But it is not nothing.

In a health advisory, the AASM said studies consistently show sleep disruption around daylight saving time changes, including less total sleep and poorer sleep quality. It also flagged drowsy driving as a real concern and advised extra care with tasks that require full alertness for at least seven days after a change.

The academy’s resource page adds that both the spring and fall changes have been associated with mood disturbances. Many of the most serious risks it lists, such as a higher risk of heart attack and stroke, are tied to the spring change, not the fall one.

None of this means you will feel bad. It means the week after Nov. 1 is a good week to protect your sleep, drive carefully if you are tired, and go easy on yourself. If you have a heart condition, a mood disorder or a sleep disorder, ask your own doctor whether any extra precautions make sense for you.

How should you adjust your sleep before Nov. 1?

The AASM’s main advice is to adjust gradually. Its tips suggest shifting your bedtime 15 to 20 minutes later each night for a few nights before the fall change, and moving other daily routines, such as meals, along with it.

Here is what that could look like if you normally sleep from 11 p.m. to 7 a.m.:

Night	Bedtime	Wake time
Wednesday, Oct. 28	11:15 p.m.	7:15 a.m.
Thursday, Oct. 29	11:30 p.m.	7:30 a.m.
Friday, Oct. 30	11:45 p.m.	7:45 a.m.
Saturday, Oct. 31 (set clocks back before bed)	11 p.m. new time	7 a.m. new time

The table is only an example. If your weekday schedule cannot slide later, even two nights of small shifts can help. The goal is to arrive at Sunday with your body closer to the new clock.

There is one important exception. The AASM says that if you are chronically short on sleep, you should not push your bedtime later. Instead, keep your normal bedtime and let the night of Nov. 1 give you a genuine extra hour of rest.

That is a popular choice. In a 2019 AASM survey, 41 percent of U.S. adults said they planned to use the extra hour to sleep.

How do you help kids adjust to the time change?

Children are often the hardest part of the fall change, because many young kids wake at the same body-clock time no matter what the clock says. In its 2026 guidance on the end of daylight saving time, the AASM notes that children and adolescents may need more time to adapt and recommends keeping bedtime routines steady.

For an early-waking toddler, a practical version of the gradual shift looks like this:

1. Starting a few nights before, push bedtime later in 15-minute steps.
2. Move dinner, bath and story time with it, so the whole routine slides.
3. Keep the bedroom dark in the early morning with blackout shades.
4. Once it is time to get up, open the curtains or head outside for daylight.
5. Hold the new schedule steady through the week, including the weekend.

Expect a few rough mornings anyway. Most kids settle within several days, but every child is different. If sleep problems last for weeks, talk to your pediatrician.

What should you do on Sunday and the week after?

The AASM’s tips for the change itself are straightforward:

• Set clocks back Saturday evening and go to bed at your normal time on the new clock.
• Keep it dark until your target wake time. The academy advises minimizing light exposure in the fall until your planned wake-up, so an early sunrise does not reset you to the old schedule.
• Then get morning light. Its 2026 guidance recommends early morning sunlight in the days after the change to help reset your internal clock. A walk to the subway or a coffee by the window counts.
• Keep a consistent wake time, including on weekends.
• Watch afternoon caffeine, especially while your body is adjusting.
• Be careful behind the wheel. If you drive for work or commute by car, the first week is the time to take drowsiness seriously.

According to that same guidance, most people adjust within a few days.

How much sleep do adults need?

The AASM recommends at least seven hours a night for adults, and eight for teens, before and after the time change. The Centers for Disease Control and Prevention recommends seven or more hours for adults ages 18 to 60, seven to nine hours for ages 61 to 64, and seven to eight hours for adults 65 and older.

The CDC’s everyday habits for better sleep apply all winter, not just this week:

• Go to bed and get up at the same time every day.
• Avoid caffeine in the afternoon or evening.
• Avoid large meals and alcohol before bedtime.
• Turn off electronic devices at least 30 minutes before bed.

Why do darker evenings make people feel low?

After Nov. 1, sunset arrives an hour earlier on the clock, and the commute home happens in the dark for much of the city. Some people notice their energy and mood dip as the days shorten.

A few small habits can help: get outside in daylight when you can, keep moving, and protect a regular sleep schedule. The end of the year can feel heavy for many reasons, and our pieces on why December feels heavy and the overwhelm season look at that stretch more closely.

If low mood lasts for two weeks or more, or starts to affect work, relationships or daily life, talk to a doctor or licensed mental health professional. Seasonal mood changes are common and treatable.

When should you see a doctor about sleep?

A rocky few days after the time change is normal. A pattern is not. Consider talking to your doctor if you:

• Regularly have trouble falling or staying asleep.
• Feel tired during the day even after seven or more hours in bed.
• Snore loudly or have been told you stop breathing during sleep.
• Find yourself nodding off while driving or at work.

The AASM suggests that people with ongoing sleep trouble talk to a doctor or get help from an accredited sleep center. This article is general information, not medical advice, so check with a licensed professional about your own situation.

Back in that Park Slope walk-up, the plan is already in motion. Bedtime slid 15 minutes later on Wednesday, then again on Thursday and Friday. The blackout shade is down, and the clocks get changed before bed on Saturday. On Sunday morning, if the toddler still calls out at 5:30, it will at least be closer to the new 6 a.m. By midweek, with a little morning light and a steady routine, the whole apartment should be back on New York time.

Frequently asked questions

Do we gain or lose an hour of sleep when the clocks fall back?

You gain an hour on the clock. At 2 a.m. on Sunday, Nov. 1, 2026, clocks go back to 1 a.m., so the night is an hour longer. Whether you actually sleep longer depends on your body clock, and kids and early risers often wake at their usual body time.

How long does it take to adjust to the fall time change?

Most people adjust within a few days, according to the American Academy of Sleep Medicine. Children and teens may take longer. Shifting your schedule gradually beforehand can shorten the adjustment.

Should I go to bed later the night before the time change?

Sleep experts suggest moving bedtime 15 to 20 minutes later each night for a few nights before the fall change, then setting clocks back Saturday evening and going to bed at your normal time. If you are already short on sleep, keep your usual bedtime and use the extra hour to rest.

Do phones change the time automatically on Nov. 1?

Most smartphones and computers set to update automatically will switch at 2 a.m. local time. Appliances, car clocks and wall clocks usually need to be changed by hand.

Is it better to use the extra hour to sleep or stay up?

If you are not getting enough sleep, using the extra hour for rest is a reasonable choice, and the AASM specifically says sleep-deprived people can benefit from it. If you sleep well already, a gradual shift in bedtime may help your body clock line up with the new time faster.
