Daylight Saving Time: How to Adjust and Protect Your Sleep

The time shift can disrupt sleep and energy levels. We have a few tips to help you adjust smoothly.

Every year, millions of people experience the effects of Daylight Saving Time (DST), whether it's the lost hour in spring or the gained hour in fall. While the intention behind DST was originally to conserve energy and maximize daylight hours, its modern benefits remain debated. What’s certain, however, is that shifting the clock can disrupt our sleep, mood, and overall well-being. The body’s internal clock, or circadian rhythm, thrives on consistency, and even a one-hour change can feel like mild jet lag. Understanding how to minimize the impact of this transition can help you maintain your energy levels and protect your sleep schedule.

The Challenge of the Time Shift

Adjusting to DST isn’t just about losing or gaining an hour, it’s about how that shift affects our biological rhythms. Here’s why the transition can be challenging:

• Circadian Rhythm Disruption: Your body is programmed to follow a natural sleep-wake cycle based on light exposure. DST throws this off, making mornings feel too early and nights feel too late.

• Sleep Deprivation: Many people don’t adjust their sleep schedules in advance, leading to cumulative sleep loss when the clocks change.

• Hormonal Imbalance: Melatonin, the hormone that helps regulate sleep, is influenced by light exposure. A sudden shift can interfere with melatonin production, making it harder to fall asleep or wake up feeling refreshed.

• Mood and Productivity Drops: Poor sleep quality can lead to irritability, difficulty concentrating, and lower productivity during the adjustment period.

Feeling out of sync? Daylight savings can impact your internal clock—small adjustments can help.

Avoiding the Slump: How to Transition Smoothly

To minimize the negative effects of DST, gradual adjustments and good sleep habits are key. Here are some strategies to help your body adapt:

• Start the Adjustment Early: A few days before the time change, shift your bedtime and wake-up time by 15–30 minutes each day to ease into the new schedule.

• Prioritize Natural Light: Get outside in the morning to help regulate your circadian rhythm and signal your body that it's time to be awake.

• Limit Evening Screen Time: Blue light from screens suppresses melatonin production. Reducing screen exposure before bed can improve sleep quality.

• Maintain a Consistent Sleep Schedule: Even after DST, sticking to a regular bedtime and wake-up time helps reinforce your body’s internal clock.

• Use Relaxation Techniques: Deep breathing, stretching, or a warm bath before bed can help signal to your body that it’s time to wind down.

Prioritizing good sleep hygiene can help your body adjust to the time change.

Sleep Hygiene: The Key to Resilient Rest

Good sleep hygiene ensures that even with external disruptions like DST, your sleep remains as restful as possible. Consider these foundational habits:

• Keep Your Bedroom Dark and Cool: Light-blocking curtains and a comfortable sleep environment can prevent restlessness.

• Avoid Stimulants Late in the Day: Caffeine and heavy meals too close to bedtime can interfere with falling asleep.

• Stick to a Wind-Down Routine: A consistent pre-bed routine signals your brain that it’s time to relax.

• Be Mindful of Naps: While naps can help with daytime sleepiness, avoid long or late naps that may interfere with nighttime sleep.

Protect Your Sleep Year-Round

Daylight Saving Time may be an unavoidable reality for many, but it doesn’t have to derail your sleep. By preparing in advance, practicing good sleep hygiene, and understanding how to reset your internal clock, you can minimize the discomfort and keep your energy levels steady. Prioritizing sleep isn’t just about adjusting to DST. It’s about maintaining overall health and well-being all year long.
