Key Takeaways
- The end of daylight saving time can throw off your body's internal clock, even though it only shifts the time by one hour.
- Light and darkness have the biggest effect on your body clock, so darker evenings and earlier sunrises can change when you feel sleepy or alert.
- Many people feel tired, wake up too early, or feel 'off' for a while after the change.
- Getting morning light and keeping a steady wake time can help your body adjust faster.
- Bogan Sleep Consultants is a team of experienced sleep specialists in Columbia, SC, and you can request an appointment with Bogan Sleep Consultants online if sleep problems linger after the time change.
Why Even a One-Hour Time Change Affects Your Circadian Rhythm?
Daylight saving time ended at 2 a.m. on Sunday, November 1, when clocks across most of the U.S. fell back to 1 a.m. On paper, that's an extra hour of sleep. In real life, your body doesn't always see it that way.
That's because of your circadian rhythm. Your circadian rhythm is your body's natural 24-hour clock. It helps control when you feel sleepy, when you feel alert, and many other body systems. According to the Cleveland Clinic's guide to circadian rhythm, light and dark have the biggest effect on this internal clock.
When the clocks change overnight, your body clock doesn't change with them. It still runs on the old schedule for a while. So you may wake up an hour earlier than you'd like, or feel sleepy before dinner is even cleared.
The 'Extra Hour' Myth
Many people look forward to the fall time change as a chance to catch up on rest. But the American Academy of Sleep Medicine (AASM) points out in its Sleep Education guide to the fall time change that one extra hour of sleep will not erase a long-term sleep debt. The AASM also notes that at least 30 percent of adults don't get enough sleep each night.
What Are the Advantages and Disadvantages of Daylight Saving Time?
Daylight saving time is a hot topic. Some people love long summer evenings, while others dread the twice-a-year clock changes. Here's a quick look at how daylight saving time compares to standard time.
| Daylight Saving Time (Spring to Fall) | Standard Time (Fall to Spring) | |
|---|---|---|
| Morning light | Darker mornings | Brighter mornings |
| Evening light | More daylight in the evening | Earlier sunsets |
| Main appeal | More time for outdoor activities after work or school | Morning light that better matches the body's natural clock |
| Fit with body clock | Less closely matched to natural sleep-wake timing | Closest match to human circadian biology, according to the AASM |
| Main drawback | Later sunrise can make it harder to wake up | Darker evenings can feel shorter and gloomier |
The AASM has taken a clear position on this debate. In its position statement on permanent standard time, the AASM says the U.S. should end seasonal time changes and move to permanent standard time. The group says standard time lines up best with human circadian biology, and that switching back and forth between time systems can cause harm to health and safety.
Common Symptoms After the Fall Time Change
Daylight saving time sleep disruption doesn't look the same for everyone. After the fall time change, you might notice:
- Waking up earlier than you want to
- Feeling sleepy earlier in the evening
- Trouble falling asleep at your usual bedtime
- Low energy or a foggy feeling during the day
- A dip in mood as the evenings get darker
For most people, these symptoms fade as the body adjusts to the new schedule.
How Light Exposure Helps You Adjust Faster
Because light has such a strong effect on your body clock, you can use it to your advantage. Try these steps in the days and weeks after the time change:
- Get outside in the morning. Morning sunlight helps signal to your brain that the day has started.
- Keep the same wake time every day. Waking up at your normal time, even on weekends, helps your body settle into the new schedule.
- Dim the lights at night. Bright screens and lights in the evening can make it harder for your body to wind down.
- Avoid long late-day naps. A long nap can make it harder to fall asleep at bedtime.
- Plan next year. The AASM suggests waiting to change your clocks until you're getting ready for bed, then waking up at your normal time the next morning.
Who Is Most Affected by the Time Change?
Anyone can feel thrown off by the clocks falling back. But some people may have a harder time adjusting, including:
- People who are already short on sleep. If you're carrying a sleep debt, one extra hour won't fix it, and the shift can leave you feeling worse.
- People with sleep disorders. The AASM notes that people with sleep apnea or another ongoing sleep problem may feel tired even after a full night of sleep.
- Shift workers. People who work nights or rotating shifts already ask their body clock to work against the sun.
- Parents of young kids. Children's schedules don't follow the clock, so early risers may start their day even earlier.
- Older adults. Many older adults already wake up early, and the time change can push wake-up time even earlier.
When Lingering Sleep Disruption Is Worth Mentioning to a Specialist?
Feeling 'off' for a few days after the time change is normal. But if your sleep still feels out of sync weeks later, it may be a sign of something more.
Consider talking to a sleep specialist if:
- You still can't fall asleep or stay asleep weeks after the change
- You feel very sleepy during the day, even with enough time in bed
- Your sleep schedule has drifted much earlier or later than you want
- You've noticed loud snoring, gasping, or pauses in breathing
Ongoing trouble with the timing of your sleep may point to a circadian rhythm problem. Bogan Sleep Consultants evaluates and treats circadian abnormalities and insomnia in Columbia, SC, with care plans built around each patient.

Frequently Asked Questions
How does daylight saving time affect sleep?
Changing the clocks shifts your daily schedule, but your body clock doesn't change right away. This can make you feel sleepy or wide awake at the wrong times until your body catches up.
Why am I so tired after daylight saving time?
Your body clock still runs on the old schedule for a while after the change. If you were already short on sleep, the extra hour also isn't enough to make up for a long-term sleep debt.
What are the advantages and disadvantages of daylight saving time?
Daylight saving time gives you more daylight in the evening, which many people enjoy. The downside is darker mornings and the disruption of changing clocks twice a year. The AASM supports moving to permanent standard time because it matches the body clock best.
How can I reduce daylight saving time sleep disruption?
Get sunlight in the morning, keep the same wake time every day, and dim lights in the evening. These habits help your body clock adjust faster.
When should I see a sleep specialist in Columbia, SC, after the time change?
If sleep problems last for weeks after the clocks change, or you have heavy daytime sleepiness or loud snoring, it's a good time to see a specialist. Bogan Sleep Consultants offers sleep care in Columbia, SC.
