When Time Falls Back, Sleep Can Fall Off Track

When Daylight Saving Time ends each November, the clocks “fall back” an hour — but for many people, their sleep doesn’t adjust quite as smoothly. You might notice feeling groggy, waking up too early, or struggling to focus for days (or even weeks) after the change.

While gaining an extra hour of sleep might sound like a bonus, your body’s circadian rhythm — the internal 24-hour clock that regulates sleep and wakefulness — doesn’t reset instantly.

At Lyte Psychiatry, serving Dallas and Arlington, TX, we often see patients experiencing fatigue, irritability, and mood dips around this time of year. Understanding how the time change affects your body can help you take proactive steps to restore balance and protect your mental health.

1. How the End of Daylight Saving Time Disrupts Sleep

Your Body Clock and Light Exposure

Your circadian rhythm depends largely on light signals from the environment. Morning sunlight tells your brain to produce cortisol (for energy) and suppress melatonin (the sleep hormone). When evenings suddenly darken earlier, that natural rhythm is thrown off balance.

This can cause temporary “social jet lag” — where your sleep schedule is out of sync with your biological clock.

Impact on Mood and Mental Health

Less daylight can trigger a drop in serotonin and an increase in melatonin, leading to low energy, sadness, and even symptoms of Seasonal Affective Disorder (SAD). Research from the American Academy of Sleep Medicine (AASM) shows that mood disorders, fatigue, and reduced concentration commonly spike right after time changes.

Even in Texas, where winters are mild, shorter daylight hours can still have a measurable emotional effect.

2. Common Symptoms After the Time Change

Trouble falling or staying asleep

Feeling tired even after a full night’s sleep

Waking up too early or too late

Changes in appetite or mood

Increased irritability or low motivation

Difficulty concentrating at work or school

If these symptoms last more than a couple of weeks, they may indicate an underlying sleep or mood disorder that deserves attention.

3. How to Help Your Body Adjust Naturally

1. Get Morning Sunlight

Expose yourself to natural light within an hour of waking up. It signals your brain to reset its internal clock and helps stabilize energy levels throughout the day.

2. Maintain a Consistent Routine

Stick to a regular bedtime and wake-up time, even on weekends. Going to bed too early after the time change can make it harder for your body to adjust.

3. Limit Evening Screen Time

The blue light from phones, tablets, and TVs can suppress melatonin production, delaying sleep. Turn off devices an hour before bed or use a warm light filter.

4. Avoid Heavy Meals and Caffeine Late in the Day

Late-night snacking or caffeine can interfere with sleep quality. Opt for light, calming evening routines — herbal tea, reading, or deep breathing exercises.

5. Get Moving During the Day

Exercise improves mood and sleep by promoting natural tiredness at night. Morning or afternoon workouts are best, especially when done outdoors.

4. When to Seek Professional Help

If your sleep struggles persist or are accompanied by significant mood changes, it may be time to consult a professional. Sleep disturbances can be linked to anxiety, depression, or seasonal mood changes, all of which are highly treatable with the right care.

FAQs About Sleep and the Time Change

Q: How long does it take to adjust after the time change?

A: Most people adjust within 1–2 weeks, though some may take longer depending on their sleep habits and sensitivity to light.

Q: Does the end of Daylight Saving Time affect everyone the same?

A: No. People with preexisting sleep or mood disorders — such as insomnia, depression, or ADHD — are often more affected by the disruption.

Q: Can light therapy really help?

A: Yes. Research shows that using a light therapy box for 20–30 minutes in the morning can significantly improve mood and energy levels during darker months.

Q: What’s the link between daylight and depression?

A: Reduced sunlight lowers serotonin levels, which play a key role in mood regulation. This can trigger symptoms of Seasonal Affective Disorder (SAD) or worsen existing depression.

Q: Should I change my sleep schedule before the time shift?

A: Gradually adjusting your bedtime by 15–20 minutes a few days before the change can make the transition smoother and minimize fatigue.
