Do you dread “springing forward” every March? If so, you’re not alone. The sleep loss caused by the transition to daylight saving time (DST) is rough! 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.
DST starts every second Sunday in March. We set our clocks ahead an hour before going to bed, which means we lose one hour of sleep that night. Similarly, when DST ends on the first Sunday in November, we set our clocks back an hour, giving us one glorious extra hour of sleep.
Although it doesn’t seem like losing one hour of sleep each March would have a big impact on your 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.
Essentially, the transition from standard time to DST messes with your body’s natural sleep-wake cycle, called your circadian rhythm. When this happens, your sleep gets misaligned and can suffer, making you feel more tired and less alert during the day. After DST, your bedtime will feel earlier, which can make it more difficult to fall asleep. Not to mention, it occurs on a weekend, when people are more likely to stay up late, which can further exacerbate the lack of sleep.
Your natural circadian rhythm is a 24-hour biological cycle that helps your body function. Although it’s an internal cycle, it’s influenced by your environment, particularly the light in the morning and the darkness in the evening.
In short, the whole purpose of your body’s circadian rhythm is to tell it when it’s time to wind down and sleep and when it’s time to wake. 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 (such as during the transition to DST), your body will need some time to adjust. This is why you feel so tired. 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 (although some research suggests certain individuals may need a few months to adjust).
You might be surprised by the many different ways your body reacts to a lost hour of sleep. Chronic sleep deprivation is linked to serious health problems, but even one lost hour of sleep will produce unwanted side effects, such as those listed here.
You may not be able to completely avoid the dreaded DST hangover, but you can minimize the impact of losing an hour of sleep. Although there’s no magic way to maintain your energy with a lack of sleep, one of the best ways to adjust is to prepare your body for the DST transition several days before it happens. To do so, go to bed 15 minutes earlier than you normally do and wake up 15 minutes earlier than usual. Continue shaving off 15 minutes each day leading up to DST so your body will be relatively acclimated to the change once it occurs.
Also, make sure your bedroom is conducive to sleep. You should keep it 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.
After DST starts, it will take some time for you to get your sleep habits back on track. Implementing the following tips will help:
