How Does Daylight Saving Time Affect Our Sleep?

Every year, as the seasons change, many people around the world experience the effects of Daylight Saving Time (DST) on their sleep patterns. This practice, which involves setting the clocks forward in the spring and back in the fall, was originally implemented to save energy and make better use of natural daylight. However, the impact of DST on people’s sleep can be significant and often disrupts their circadian rhythms, leading to various sleep-related issues. In this article, Gardner White will explore how Daylight Saving Time affects people’s sleep and provide some tips on how to mitigate its negative consequences.

Disrupted Circadian Rhythms

One of the primary ways DST affects sleep is by disrupting our natural circadian rhythms. Our bodies have internal clocks that regulate when we feel sleepy and when we are awake. These rhythms are influenced by light exposure, and when we suddenly change our clocks by an hour, it can take some time for our bodies to adjust.

In the spring, when we “spring forward” and lose an hour of sleep, it can be particularly challenging to adapt to the new schedule. This abrupt shift can lead to feelings of grogginess and fatigue, commonly referred to as “social jetlag.” It can take several days or even weeks for our bodies to fully adjust to the new time, during which sleep quality may suffer.

Sleep Deprivation

Another consequence of Daylight Saving Time is sleep deprivation. When we lose an hour of sleep in the spring, it can be challenging to make up for that lost time, especially if we have busy schedules. Sleep deprivation can result in reduced alertness, impaired cognitive function, mood swings, and an increased risk of accidents.

Furthermore, the shift in time can affect our ability to fall asleep at our usual bedtime. This can lead to a vicious cycle of sleep deprivation, as we struggle to get enough rest each night.

Seasonal Affective Disorder (SAD)

Daylight Saving Time can also contribute to Seasonal Affective Disorder (SAD), a type of depression that occurs seasonally, typically in the fall and winter months. When we “fall back” (coming up on November 5th!) and gain an extra hour of sleep in the autumn, the days become shorter, and daylight decreases. This reduction in natural light exposure can lead to mood disturbances, disrupted sleep patterns, and increased feelings of sadness and lethargy.

How To Cope With Daylight Savings Time

How To Cope With Daylight Savings TimeWhile we may not have control over the implementation of Daylight Saving Time, there are strategies to help mitigate its impact on our sleep:

Coping with DST for better sleep:

  1. Gradual Adjustment

    In the days leading up to the time change, try going to bed and waking up 15 minutes earlier each day to adjust your internal clock gradually.

  2. Prioritize Sleep Hygiene

    Maintain a consistent sleep schedule, create a comfortable sleep environment, and avoid stimulating activities close to bedtime.

  3. Exposure to Natural Light

    Spend time outdoors during daylight hours, as natural light can help regulate your circadian rhythms.

  4. Limit Caffeine and Alcohol

    Avoid consuming caffeine and alcohol close to bedtime, as they can interfere with your ability to fall asleep and stay asleep.

  5. Reduce Electronics Use

    The blue light emitted by screens on electronic devices can disrupt your sleep patterns. Try to avoid screens at least an hour before bedtime.


Daylight Saving Time may have been implemented with the best of intentions, but it can have significant repercussions on people’s sleep patterns and overall well-being. Understanding how DST affects your sleep and taking proactive steps to mitigate its adverse effects can help you transition more smoothly into the new time schedule and maintain a healthy sleep routine. By prioritizing sleep and practicing good sleep hygiene, you can minimize the disruptions caused by Daylight Saving Time and enjoy better rest year-round.
