Smart Sleep Tips for the End of Daylight Saving Time

Experts share simple, science-backed ways to adjust smoothly when clocks fall back.

Highlights:

Morning light helps your body clock adapt faster after the time change
Too much evening light or caffeine can delay your natural sleep rhythm
Keeping a consistent routine supports mood, energy, and heart health

When the clocks “fall back” this Sunday, it might seem like a bonus hour of rest, but scientists say the time change can quietly throw your body clock off balance. The sudden shift affects not only sleep but also mood, energy, and even metabolism. Researchers explain that the body’s circadian rhythm, the internal system that regulates sleep and wake cycles, takes several days to adjust each time we reset our clocks ().

Simple Tips to Stay Energized After the Time Change

Experts recommend a few easy adjustments to help your body adapt quickly and stay healthy:

Go to bed 15-20 minutes earlier for a few nights before the change to prepare your system.
Get bright morning light exposure soon after waking to signal your body it’s time to start the day.
Dim home lights in the evening to promote melatonin release and prepare for restful sleep.
Avoid caffeine after late morning, especially during the first week after the switch.
Take short naps (20-30 minutes) early in the day if you feel tired, but avoid late-day napping.
Eat dinner slightly earlier for the first few days to reinforce your body’s internal clock.
Step outside for at least 30 minutes of daylight daily to help reset your circadian rhythm.

Is Daylight Saving Time Good or Bad for Health?
The onset of daylight saving time (DST), commonly known as summer time, can affect your overall health and lead to unhealthy lifestyle habits.

The Science Behind the Sleep Disruption

Recent findings in Sleep and other peer-reviewed journals reveal that both “spring forward” and “fall back” adjustments disturb natural sleep patterns. While losing an hour in spring is tougher on most people, even the fall transition can cause grogginess, reduced alertness, and slower reaction times. A 2024 meta-analysis and follow-up studies found that performance, concentration, and mood often dip for several days after each time shift.

Statistics show that driving performance worsens after daylight saving transitions, especially among those who are already sleep-deprived. Some studies have linked these changes to brief increases in depressive episodes and poorer metabolic health. Although the latest U.S. registry analysis in 2025 found no significant spike in heart attacks, experts agree that vulnerable individuals might still face short-term cardiovascular strain during the adjustment period ().

How the Body Clock Responds to Time Change

Our internal rhythm is strongly influenced by light exposure. Morning sunlight signals the body to wake earlier, while evening light delays melatonin release, keeping us awake longer. During the fall time change, extra morning light helps some people adapt faster, but bright artificial lighting in the evenings can undo that progress. Experts advise dimming home lights at night to support the body’s transition.

How To Assess Circadian Rhythm Timing?
A new research shows that it is possible to measure the circadian rhythm of a person accurately with a single blood test based on measuring different levels of metabolites.

Why Routine Matters After the Shift

Keeping a regular schedule helps your body recover faster from the time change. Try waking and eating meals at consistent times, even on weekends. Maintaining steady sleep patterns strengthens your circadian rhythm and supports long-term mental and physical health.

A one-hour time change might seem small, but for your body’s internal systems, it is a noticeable shift. Respecting your natural rhythm with steady habits, light exposure, and mindful routines can make the transition easier and improve overall wellness.

As you reset your clocks, take the opportunity to reset your routine too. Small, mindful changes can help you sleep better, feel more balanced, and start each morning with renewed energy.
