Daylight saving time has its origins back before the Industrial Revolution, but it certainly has no shortage of modern-day critics. Given that the practice was first proposed in 1895 and first adopted in the 1900s, largely to conserve coal during wartime, we\u2019d say it\u2019s more than fair to debate its current relevance. We also think it\u2019s important to clear the air: in general, daylight saving time doesn\u2019t directly benefit anybody.<\/p>\n

When we \u201cfall back\u201d, or set the clocks back an hour for daylight saving, we often say we\u2019re looking forward to \u201cgaining\u201d an hour of sleep. And when we \u201cspring forward\u201d by setting the clocks ahead, we bemoan the one hour of sleep we\u2019ve \u201clost\u201d. The truth is, we\u2019re not gaining or losing anything \u2014 our bodies are simply being deceived by the different time shown on the clock. However, that doesn\u2019t mean there\u2019s no effect on our minds or bodies. Below, we\u2019ll discuss how daylight saving can throw off our rhythms and health, and how that in turn can impact our driving abilities.<\/p>\n

A rough time for circadian rhythms<\/h2>\n

Nobody wants to end up going deep into debt, and sleep debt is no exception. According to the Sleep Foundation, sleep debt refers to the difference between the amount of sleep a person needs and the amount they actually end up getting. For example, if you need to hit the golden eight hours of sleep, but only manage to sleep for six hours, you have two hours of sleep debt. And that\u2019s just for that night!<\/p>\n

Sleep debt is cumulative, and it can really throw you out of whack as it builds upon itself. Regularly getting less sleep than you need can lead to a higher risk of diabetes, hypertension, heart disease, and stroke. In the short term, lack of sleep still has significant consequences, such as affecting your focus at work, school, or while driving.<\/p>\n

If we\u2019re not careful, plenty of everyday activities can lead to sleep debt: work hours, commuting, socializing, and watching TV are the main culprits in the US. And, while there\u2019s little evidence to support the idea that daylight saving time actually affects the amount of time we sleep, that doesn\u2019t mean it isn\u2019t disruptive.<\/p>\n

Daylight saving time\u2019s alterations to our sleep-wake cycle can upset sleep for up to a week, according to some research. In fact, the cumulative effect of five consecutive days of earlier rise times suggests a net loss of sleep over the course of the week.<\/p>\n

Essentially, daylight saving causes a disruption to our circadian rhythm cycles (24-hour cycles that coordinate mental and physical systems throughout the body). When properly aligned, circadian rhythms promote restful, restorative sleep. A disturbance to these cycles, however, can lead to behavioral and mood upsets.<\/p>\n

\u201cFalling\u201d and \u201cspringing\u201d at the expense of safety?<\/h2>\n

So, how does daylight saving time affect safety behind the wheel? When disrupted from their natural cycle, as in the case of daylight saving, our circadian rhythms can cause a loss of sleep, or worse. Plenty of people experience physical, mental, and behavioral changes following this disturbance. Unfortunately, this can lead to drowsiness, which can lead to more car accidents.<\/p>\n

Recent research has found that springing forward \u2014 the springtime practice of moving clocks ahead by an hour \u2014 leads to a 6% increase in fatal car accidents in the United States<\/a>. This is due both to people disrupting their normal sleep patterns and driving to work in darkness. Research also shows a spike in\u00a0strokes, workplace injuries, and other complications following the leap. Shockingly, other studies have even shown that daylight saving can lead to harsher judicial sentencing.<\/p>\n

There are changes in car accident patterns resulting from \u201cfalling back\u201d as well, with a decline in morning accidents and a spike in evening accidents. What\u2019s more, there\u2019s even a potential correlation between daylight saving time and heart health \u2014 negative in the spring, and positive in the fall. Hospitals report a 24% spike in heart attack visits in the spring<\/a>, and a drop of 21% in the fall.<\/p>\n

Driving safely during daylight saving<\/h2>\n

With the end of daylight saving time coming up on November 5th, now is as good a time as any to brush up on your safe driving habits<\/a>. Maintaining a proper following distance, adjusting (and using!) your mirrors properly, and avoiding distracted driving<\/a>: these are only a few of the basic safety precautions you should take that may quite literally save lives.<\/p>\n

To avoid putting others at risk, it\u2019s also essential to stay in tune with your body and recognize when you\u2019re just too tired to drive. Drowsy driving causes thousands of injuries and deaths every year \u2014 as we\u2019ve discussed, daylight saving may only contribute to these numbers.<\/p>\n

As a starting point, here is a list of simple steps you can take to be safer on the road.<\/p>\n
