When Daylight Saving Time ends and the clocks “fall back” an hour, it might seem like a small shift — but your body doesn’t always agree. That single hour can throw off your internal body clock, or circadian rhythm, which regulates your sleep, energy, and mood.
Even though we technically gain an extra hour of rest, many people experience fatigue, irritability, difficulty concentrating, and even mild seasonal depression in the days that follow.
Your brain relies on sunlight to regulate hormones like melatonin (which helps you sleep) and cortisol (which helps you wake up and stay alert). When evening darkness comes an hour earlier, your brain gets confused — releasing melatonin too soon and leaving you sleepy before bedtime.
Less sunlight also means less serotonin, the neurotransmitter that stabilizes mood and energy. According to the National Institute of Mental Health (NIMH), serotonin activity can drop by up to 30% in winter months, leading to seasonal mood dips or Seasonal Affective Disorder (SAD).
Even in sunny Texas, shorter daylight hours can subtly affect how you feel, sleep, and function.
Difficulty falling asleep or waking up too early
Feeling tired or groggy throughout the day
Changes in appetite or sugar cravings
If these symptoms last more than a week or interfere with daily life, your circadian rhythm may be out of sync — and it’s worth taking steps to reset it.
Sunlight is nature’s alarm clock. Try to get 15–30 minutes of natural light within the first hour of waking. Go for a walk, have your morning coffee by a bright window, or open blinds immediately to help your brain recalibrate.
Go to bed and wake up at the same time every day, even on weekends. This consistency helps your body clock adjust faster. If you feel sleepy earlier in the evening after the time change, resist the urge to go to bed too soon.
Exercise boosts serotonin and regulates energy. Aim for 30 minutes of physical activity daily, preferably earlier in the day to improve sleep at night.
If sleep struggles, fatigue, or mood changes last more than two weeks, it might be more than just a temporary adjustment. You could be experiencing Seasonal Affective Disorder (SAD) or another mood-related condition.
Cognitive Behavioral Therapy (CBT) to reframe negative thoughts
Medication management when appropriate
Light therapy or lifestyle strategies for circadian realignment
Telehealth sessions for convenience and accessibility
We’re here to help you reset, recharge, and feel your best — all year long.
You don’t have to dread the time change or the shorter days that follow. With the right strategies — and compassionate support — you can protect your mood, energy, and sleep this season. At Lyte Psychiatry, we specialize in helping adults and adolescents manage the mental and physical effects of stress, sleep changes, and seasonal transitions.
Q: How long does it take to adjust after the time change?
A: Most people adapt within 5–10 days, though sensitivity varies. Keeping consistent sleep and wake times helps your body reset faster.
Q: Why do I feel more tired after gaining an hour?
A: Your circadian rhythm is tuned to routine — not the clock. The sudden shift disrupts melatonin release, temporarily throwing off your sleep-wake balance.
Q: Can the time change affect my mood?
A: Yes. Reduced sunlight and changes in sleep patterns can impact serotonin levels, increasing the risk of low mood or depression.
Q: Is light therapy effective?
A: Absolutely. Using a light therapy box for 20–30 minutes in the morning can significantly improve mood and energy during shorter days.
Q: When should I seek professional help?
A: If you notice persistent sadness, hopelessness, or ongoing fatigue for more than two weeks, it’s time to reach out for support.
