How the End of Daylight Saving Time Affects Your Sleep
Why the end of daylight saving time disrupts sleep even though you gain an hour, a seven-day adjustment plan, and when to get sleep or mood symptoms checked.
Published by Lyte Psychiatry · Meet our care team
The end of daylight saving time gives you an extra hour on the clock, but your body clock does not move with it. For several days many people wake too early, slump in the late afternoon and feel low as evenings turn dark by dinner. The fix is mostly light and routine, and this guide gives you a seven-day plan.
This article is for adults in Texas who notice their sleep or mood wobble every November, for parents and shift workers juggling schedules that do not shift neatly, and for anyone with anxiety, depression or bipolar disorder for whom a few bad nights can matter more than they do for others.
When does daylight saving time end in 2026?
As of October 2026, the National Institute of Standards and Technology (NIST) lists the end of daylight saving time as 2:00 a.m. on the first Sunday of November, which falls on November 1, 2026, when clocks go back one hour. Texas observes daylight saving time, so the change applies statewide.
Rules about daylight saving time are set by federal law and by each state's choice to observe it, and they can change, so check a current source each year. The American Academy of Sleep Medicine (AASM) has stated a position in favor of permanent standard time, which is the time we are returning to in November.
Why does gaining an hour still disrupt sleep?
Gaining an hour disrupts sleep because your internal clock, not the wall clock, decides when you feel sleepy and alert. The National Institute of General Medical Sciences (NIGMS) explains that light has the biggest influence on circadian rhythms and that a master clock in the brain controls melatonin release based on the light your eyes receive.
Think of it as a one-hour trip west without the travel. On Sunday morning your body still thinks 6 a.m. is 7 a.m., so you wake early. By evening, darkness arrives an hour sooner by the clock, and the body reads early darkness as a signal to wind down. The result is a few days of early waking, afternoon sleepiness and odd hunger times until the internal rhythm catches up.
Who feels the fall time change the most?
Early risers, shift workers, parents of young children, older adults and people with mood disorders tend to feel the change most. The National Heart, Lung, and Blood Institute (NHLBI) describes circadian rhythm disorders as a body clock out of sync with the environment, with symptoms including extreme daytime sleepiness and decreased alertness. A one-hour change does not cause a disorder, but it can make an existing tendency more visible.
Examples of how it shows up:
- Early risers who already wake at 5:30 now wake at 4:30 for a week.
- Night owls may feel briefly better, then slide later as dark evenings invite late screens.
- Shift workers may get an extra hour on an overnight shift and lose the rhythm they had built. See our guide on shift work, sleep and mood.
- Young children and pets keep their old schedule and wake the household an hour early.
Does the end of daylight saving time affect mood?
The end of daylight saving time can nudge mood because it makes evenings dark suddenly rather than gradually, and darkness and sleep loss both affect how we feel. The National Institute of Mental Health (NIMH) describes seasonal affective disorder as a recurrent pattern of depression lasting four to five months that returns in at least two consecutive years, and notes it is more common farther north than in states like Texas and Florida.
Sleep loss on its own can also flatten mood for a few days, which is one more reason to protect the routine during the first week. So the clock change is not the cause of seasonal depression, but for people prone to it, the first week of November is often when they first notice the dip. If low mood, low energy or oversleeping persist past the adjustment period, read our guide to winter blues versus seasonal depression and consider an evaluation.
How do you adjust to the time change? A seven-day plan
You adjust fastest by anchoring your wake time and using light deliberately. The AASM advises setting clocks back on Saturday evening, keeping your normal bedtime, and minimizing light exposure in the evening. Here is a day-by-day example plan:
- Saturday (before the change): Set clocks back before bed. Go to bed at your usual clock time. Do not stay up an extra hour "because you can."
- Sunday: Get up at your usual clock time even if you woke earlier. Get outside within an hour of waking, 15 to 30 minutes if you can. Eat meals at the new clock times.
- Monday: Same wake time. Morning light again. Skip the afternoon nap, or cap it at 20 minutes before 3 p.m.
- Tuesday: If you are waking early, resist screens in bed. Dim lights after dinner and start your wind-down 30 minutes before bed.
- Wednesday: Cut caffeine after lunch. MedlinePlus recommends avoiding afternoon and evening caffeine, keeping the same bed and wake time daily, and getting sunlight during the day.
- Thursday: Add an evening walk or light activity before dark if your schedule allows. Keep alcohol minimal; it fragments sleep.
- Friday: Review the week. If you are sleeping through to your wake time, hold the routine. If not, keep going for another week before deciding something else is wrong.
Our post on resetting your body clock after falling back covers variations for people with irregular schedules.
What should you track before a sleep or mood appointment? A checklist
Tracking for two weeks turns a vague complaint into something a clinician can act on. The AASM's sleep diary covers two weeks and asks you to record caffeine, alcohol, exercise, naps, medications and the type of day. Use this checklist:
- Time you got into bed and roughly when you fell asleep
- Number and length of night wakings
- Final wake time and the time you got up
- Naps, caffeine, alcohol and exercise, with times
- Mood each evening on a 1 to 10 scale
- Any morning or evening light exposure outdoors
- Medications and the time you took them
What to say at the visit: "Since the clock change I have been waking at 4:30 most days, my mood drops after dark, and here is my two-week diary." That sentence gives a clinician a timeline, a symptom and data. See what to track before a sleep appointment for a printable version.
When should you get help sooner?
Get help sooner if sleep problems last beyond two or three weeks after the time change, or if they come with mood changes. The Centers for Disease Control and Prevention (CDC) notes that adults aged 18 to 60 need seven or more hours of sleep and recommends a consistent bed and wake time, no large meals or alcohol before bed, and screens off 30 minutes before sleep.
Red flags that should not wait for the body clock to settle:
- Early waking with low mood, loss of interest or hopelessness most days
- Needing much less sleep than usual but feeling energetic, especially with a history of bipolar disorder
- Falling asleep while driving, or near-misses on the road
- Loud snoring with gasping, or waking unrefreshed every day regardless of hours slept
- Using alcohol or sleep aids nightly to get to sleep
- Thoughts of death or of harming yourself
For insomnia that has settled in, the AASM recommends cognitive behavioral therapy for insomnia as the first-line treatment for chronic insomnia disorder in adults, and notes it can be delivered in person, by video or online. Our article on CBT-I without sleeping pills explains how it works.
The time change in Texas: dark commutes and long days
In most of Texas, the November change means sunset moves to around dinnertime, and evening commutes happen in the dark for the rest of the year. That shift reduces the natural light many people were getting on the way home, which is often their only outdoor light of the day.
A practical response is to move outdoor time to the morning, even ten minutes while coffee brews, and to open blinds at your desk if you work indoors. Weekend daylight counts too, so a Saturday morning walk helps more than a late sleep-in. Lyte Psychiatry offers telehealth visits to patients who are physically located in Texas at the time of the visit, which can make a mid-day appointment possible without an evening drive. Telehealth and insurance rules vary by state and plan, so confirm what applies to you.

Common Questions
Frequently Asked Questions
When does daylight saving time end in 2026?
As of October 2026, the National Institute of Standards and Technology lists the end of daylight saving time as 2:00 a.m. on the first Sunday of November, which is November 1, 2026. Clocks go back one hour. Texas follows this schedule. Most phones update automatically, but ovens, cars and some alarm clocks do not.
Why do I feel worse after gaining an hour of sleep?
Your body clock does not move when the wall clock does. The internal rhythm that controls alertness and melatonin release keeps running on the old schedule for several days, so you may wake too early, feel sleepy in the late afternoon and hungry at odd times. Darker evenings also reduce the light cues that normally keep the rhythm steady.
How long does it take to adjust to the time change?
Many people settle within a few days to a week. The American Academy of Sleep Medicine notes that light and dark are the most powerful timing cues, so morning light and dimmer evenings speed adjustment. If sleep is still disrupted two or three weeks later, the time change is probably not the main cause and something else deserves a look.
Does the end of daylight saving time cause seasonal depression?
Not by itself. Seasonal affective disorder follows the seasons, not the clock, and the National Institute of Mental Health describes it as a recurrent pattern lasting four to five months. The clock change does make evenings darker suddenly, which can bring the first noticeable dip in mood for people who are prone to it. Track your mood and get help if it persists.
Should I take melatonin to adjust to the time change?
Most people do not need it for a one-hour shift, and timing matters more than dose. Morning light, a steady wake time and a dim evening do the same job without a supplement. If you are considering melatonin, especially with other medications or during pregnancy, ask your prescriber or pharmacist first rather than guessing.
Who is most affected by the fall time change?
Early risers, shift workers, parents of young children, older adults and people with mood disorders tend to notice it most. Early risers wake even earlier for a while. Young children and pets do not read clocks and keep their old schedule. People with bipolar disorder or depression may find that sleep disruption nudges mood, so a steady routine matters most for them.
Can Lyte Psychiatry help with sleep problems after the time change?
