How Daylight Saving Time Affects Your Health and How to Prepare
Alright, let’s talk about something that sneaks up on us every year—daylight saving time. This Sunday at 2 a.m., most of the U.S. will "spring forward," meaning we lose an hour of sleep. Sounds like just a minor inconvenience, right? Well, it turns out, this shift can do more than just make you groggy in the morning. It can actually have real effects on your health.
You see, our bodies run on a natural internal clock, called the circadian rhythm, which is regulated by light exposure. When we suddenly push the clocks forward, that extra evening light can throw everything out of sync. It can take days, sometimes even weeks, for your body to adjust. And during this time, studies have shown an increase in heart attacks, strokes, and even car accidents. Yep, that’s right—just that one-hour shift can impact your heart and reaction time in serious ways.

Think about it—morning light helps reset our internal clock, while darkness at night triggers melatonin production, the hormone that makes us sleepy. But with daylight saving time, our brains get confused. We stay up later, but our alarms still go off at the same time. That means less sleep, and sleep deprivation has been linked to heart disease, obesity, and cognitive decline. Not exactly something to brush off.
So what can you do to prepare? Experts suggest gradually shifting your bedtime about 15 to 20 minutes earlier for a few nights leading up to the time change. Also, make sure to get outside in the morning sunlight—it helps reset your body clock. Avoid too much caffeine or screen time before bed, since both can delay your sleep cycle even more. And if you can, try to avoid super early morning tasks on Monday, when your body is still adjusting.
Of course, the debate about whether we should even keep switching our clocks twice a year is still ongoing. Some states have already opted out, like most of Arizona and Hawaii, while others are pushing for a permanent daylight saving time or just sticking with standard time. But until a decision is made, we’ll be stuck making this adjustment twice a year.
So, as we head into this weekend, do yourself a favor—plan ahead, get some extra rest, and ease into the time change. Your body will thank you!
