How Daylight Saving Time Affects Mental Health

Daylight saving time can affect mental health by shifting when you get light and dark, which nudges your body clock out of sync with your schedule. For a few days to a week, that can mean poorer sleep, low energy, irritability and lower mood. People with depression, anxiety or bipolar disorder may feel it more, and darker evenings in fall can add to winter low mood.

This article is for adults and families in Texas who notice they feel off around the clock change and want a simple way to adjust. If you mainly want sleep tips, see how the end of the time change affects your sleep. This guide focuses on mood.

When is the 2026 time change?

The 2026 fall time change happens on Sunday, November 1. As of October 2026, the National Institute of Standards and Technology (NIST) states that daylight saving time ends at 2:00 a.m. on the first Sunday of November, when clocks go back one hour.

Phones and computers usually update on their own. Wall clocks, car clocks and some alarm clocks do not, so set them on Saturday evening.

Why does the clock change affect mood?

The clock change affects mood because your brain's master clock runs on light, and the change suddenly moves light to a different part of your day. The National Institute of General Medical Sciences (NIGMS) explains that light has the biggest influence on circadian rhythms and that the master clock controls melatonin based on the light your eyes receive.

When your body clock and your social clock disagree, sleep, alertness and mood can slip. The National Heart, Lung, and Blood Institute (NHLBI) notes that when the body clock is out of sync with the environment, symptoms can include daytime sleepiness, decreased alertness and problems with memory and decision-making.

The American Academy of Sleep Medicine (AASM) calls light and dark the most powerful cues for the timing of the body clock, and it supports permanent standard time for that reason.

Who is most affected by the time change?

People whose sleep or mood is already fragile tend to notice the time change most. That includes:

• People with depression, anxiety or bipolar disorder, for whom sleep changes can affect symptoms.
• People with a history of seasonal affective disorder (SAD).
• Teens and young adults with early school or work start times.
• Parents of young children whose schedules shift.
• Shift workers and people with irregular schedules.
• People already short on sleep.

Is it the time change or seasonal depression?

The time change usually causes a short adjustment, while seasonal depression lasts for weeks and returns most years. The National Institute of Mental Health (NIMH) describes winter-pattern SAD as depression that starts in late fall or early winter and eases in spring and summer, with symptoms such as low energy, oversleeping and craving carbohydrates.

A rough guide: if you feel off for a week and then settle, it is likely adjustment. If low mood, withdrawal and fatigue build through November and stay, it may be more. Our article on winter blues or seasonal depression explains the difference.

A seven-day plan to adjust smoothly

A short plan works better than trying to push through. The AASM suggests setting clocks back on Saturday evening and keeping your normal bedtime. Start a few days before November 1 and continue through the following week.

1. Three days before: pick a fixed wake time for the next two weeks, including the weekend.
2. Two days before: plan two daily light breaks, one in the morning and one in late afternoon.
3. Saturday evening: change manual clocks and go to bed at your usual clock time.
4. Sunday: get outside within an hour of waking. Keep naps short and early.
5. Monday to Wednesday: move your body each day. The CDC notes that physical activity helps you feel better right away and sleep better.
6. Thursday: plan one evening activity with another person, so dark evenings are not empty.
7. Next weekend: check in. Are sleep, energy and mood back to normal? If not, keep going for another week and note what is still off.

How can light, sleep and routine help your mood?

Light, sleep and routine help by giving your body clock steady signals, so it resets faster. MedlinePlus recommends going to bed and waking up at the same time every day, getting sunlight during the day, and avoiding naps after 3 p.m.

• Morning light: open blinds right away or spend 15 to 30 minutes outside.
• Evening light: keep lights warm and lower in the hour before bed.
• Caffeine: MedlinePlus advises avoiding caffeine in the afternoon and evening.
• Meals: keep regular meal times so your days have a steady shape.
• Connection: make plans for darker evenings, such as a call, a class or a walk with a friend.

Is springing forward harder than falling back?

For sleep, springing forward is usually harder, because you lose an hour; for mood, falling back can be tougher, because evenings get dark sooner. When daylight saving time begins in March, many people run short on sleep for several days. When it ends in November, the extra hour helps sleep on paper, but afternoon light disappears earlier.

The AASM's position in favor of permanent standard time reflects its view that the body clock is better aligned with standard time. Whatever your view on that debate, the practical point is the same: plan for both changes rather than expecting them to pass unnoticed.

How can families help kids and teens adjust?

Families help children adjust by shifting routines gradually and keeping mornings bright. Because NIGMS notes that light is the strongest signal to the body clock, morning light is as useful for children as for adults.

• Move bedtime by 10 to 15 minutes a night over several nights, rather than all at once.
• Keep wake-up times the same on school days and weekends for the first week.
• Get outside for breakfast, the walk to school or a short play break.
• Expect some crankiness for a few days, and lower demands where you can.
• Watch for a teen whose mood, sleep or school performance keeps slipping after the first week.

What to tell your family or clinician: a checklist

If the time change hits hard, a short note helps others understand and helps a clinician spot patterns. NIMH notes that SAD symptoms recur at the same time of year, so writing down when your symptoms start is useful.

• "I usually feel lower when the clocks change. Can we keep evenings simple this week?"
• When symptoms began, and whether this happens most years.
• Changes in sleep length, appetite, energy and interest in activities.
• Any periods of unusually high energy or little need for sleep.
• Current medicines, and any questions about timing to ask your prescriber.

When should you get help sooner? Red flags

Get help sooner if mood or sleep has not recovered within two weeks, or if any of these appear. NIMH advises talking with a health care provider if you think you may have SAD or depression.

• Low mood, hopelessness or loss of interest most of the day for two weeks or more.
• Sleeping much more or much less than usual and being unable to function at work or school.
• Several nights of very little sleep with high energy, racing thoughts or risky behavior.
• Drowsiness that makes driving unsafe.
• Thoughts of death or suicide. Call or text 988.

The time change in Texas

Texans still feel the end of daylight saving time, even though winters here are milder and sunnier than in northern states. NIMH notes that SAD is more common farther north, and that people in Alaska or New England are more likely to develop it than people in Texas or Florida.

Less likely does not mean never. After the change, sunset in much of Texas comes around or before the time many people finish work, so evening light and activity take planning. If you have a mood disorder, keep your regular appointments through November and December.
