Does daylight saving time affect your health? Is it good or bad for you?

As we hit the first weekend in November 2024, the action of rolling back time – modern devices negating our need to remember – returns. Daylight saving time (DST), as it’s known, has long been debated, with some praising the extra daylight in the evenings while others worry about its effects on health. And studies have shown that shifting the clock by just 60 minutes can indeed have a surprising impact on your well-being.

Daylight savings and sleep patterns

Adjusting the clock disrupts your body’s circadian rhythm, Harvard Health tells us, often leading to sleep disturbances. This misalignment can cause sleep deprivation, which affects mood and cognitive functions. Research suggests that moving into DST can increase the risk of heart attacks and strokes.

Daylight savings and accidents

Sleep loss tied to DST has been linked to more traffic accidents. There’s a 6% rise in fatal car crashes during the workweek following the spring shift, according to Psychology Today. This change can reduce alertness, making daily tasks more dangerous.

Daylight savings and mental health

DST can also affect mental well-being. Sleep disruption may worsen mood disorders like depression and anxiety. Less daylight in the evening affects melatonin production, which can worsen seasonal affective disorder.

Is daylight saving time beneficial?

While DST was created to save energy, some modern studies question its effectiveness. Given the health risks, some experts advocate eliminating DST, arguing that the downsides outweigh any benefits.

How to mitigate the effects of daylight savings

To reduce DST’s impact on your health, try adjusting your sleep schedule in the days before the time change. Get sunlight in the morning, and keep a regular sleep routine to help your body adjust.

In short, while extra daylight can be appealing, DST may do more harm than good. Knowing these effects can help you protect your health during the transitions.
