How to Reset Your Sleep After a Time Change

Do you dread “springing forward” every March? Does “falling back” in November leave your sleep schedule a mess for days or even weeks? If so, you’re not alone. The sleep loss caused by the transition to daylight saving time (DST) can be a challenge. For some people, it can increase symptoms of sleep deprivation, making them feel more irritable, moody, and tired during the day.

If you typically struggle with the DST transition, there’s a scientific reason for this, but there are ways to lessen the negative effects on your body and mind. Fortunately, we have some sleep tips that will help you adjust. First, let’s take a closer look at how daylight saving time affects your sleep cycle and why it matters.

How Does Daylight Saving Time Affect Your Sleep Cycle?

The United States has observed Daylight Saving Time since 1966, with the exception Hawaii and the majority of Arizona—the Navajo Nation in the northeastern part of the state does change its clocks. DST starts every second Sunday in March, when clocks are set ahead by one hour. Then, on the first Sunday of November, clocks are set back one hour, returning most of the US to standard time.

Although it doesn’t seem like losing one hour of sleep each March would have a major affect on mental and physical health, this time of year is associated with an uptick in insomnia, mood disorders, heart problems, and even car crashes — all of which highlight the potential effects DST can have on your health. A European study published in 2021 found that motorist accidents increased more than 51% when comparing the weeks before and after the March time change. This is consistent with a widely cited 2009 study that found that workers sustain more workplace injuries and injuries of greater severity on the Monday after the time change.

Time-change related sleep problems are less common after the November “fall back” time change, though some report difficulty adjusting to a new wake-up time.

Essentially, the transition from standard time to DST disrupts the body’s natural sleep-wake cycle, known as your circadian rhythm. When this happens, your sleep gets misaligned, making you feel more tired and less alert during the day. After losing sleep to daylight saving time, your bedtime will feel earlier, which can make it more difficult to fall asleep.

Understanding Circadian Rhythm

Your natural circadian rhythm is a 24-hour biological cycle that helps your body function. Although it’s an internal cycle, it can be influenced by the environment, particularly light in the morning and the darkness in the evening. 

The circadian rhythm is meant to signal to your body when it is time to wind down and sleep, and when it is time to wake up. At around 9 p.m., your body starts secreting the hormone melatonin, which promotes sleep. Melatonin levels start dropping off in the morning, promoting wakefulness and alertness.

Unfortunately, whenever this natural biological cycle is altered—like with jet lag or a time change—it creates a circadian misalignment, leading to lost sleep. The good news is that sleep research experts say it usually only takes a day or two for your body’s internal clock to adjust to the change. Some individuals may experience longer-term repercussions due to a so-called “sleep debt,” meaning adjustments can take as long as a few months.

What Happens When You Lose an Hour of Sleep?

While you can only lose one hour of sleep due to daylight saving time in the spring, the body can undergo real stress. Chronic sleep deprivation is linked to serious health problems, but studies suggest sleeping less than 7 hours a night can produce unwanted side effects, such as:.

  • Increased caloric intake: Sufficient sleep is linked to appetite-regulating hormones, meaning losing an hour of sleep may make you more hungry.  
  • Reduced stamina: Your physical endurance is also likely to suffer. So when you head to the gym for your daily workout, you’ll likely feel sluggish.‍
  • Decreased focus: Your performance at work or school will also be affected by the lack of sleep. You may have trouble concentrating, and your mind may wander more than it usually does.

How to Adjust to a Lack of Sleep

While completely avoiding sleep problems related to daylight saving time, there are ways to minimize their effect.  One of the best ways to adjust is to prepare your body for the DST transition several days before it occurs. To do so, go to bed 15 minutes earlier than you normally would and wake up 15 minutes earlier than usual. Continue shifting your sleep cycle15 minutes each day leading up to the daylight saving time change  so your body will be relatively acclimated to the change once it occurs.

Also, make sure you are practicing good sleep hygiene. You should keep your bedroom dark at night to help with your body’s natural production of melatonin, and the temperature should be between 60 and 68 degrees Fahrenheit while you sleep.

Get Your Sleeping Habits Back on Track

After DST starts, it will take some time for you to get your sleep habits back on track. Implementing the following tips will help:

  • Get lots of bright light in the early mornings.
  • Implement a regular sleep schedule by going to bed and waking up at the same time every day.
  • Take naps if you need to. Just try to keep them short and make sure they’re not too close to your normal bedtime.
  • If you use technology two hours before bedtime, make sure to set your device to dim lighting, and only consume content that won’t produce stress right before bed.
  • Limit caffeine intake in the afternoons and alcohol consumption four hours before bed.
  • Set your alarm to wake you during your lightest cycle of sleep, so you feel more refreshed and awake first thing in the morning.
