Daylight Saving Time is Ending in the US: How Does It Affect Health and How Can You Prepare for It?

As 2024 approaches, daylight saving time (DST) will soon come to an end in the United States, specifically on November 3rd, Sunday, at 2 a.m. Many wonder about the effects of this transition on our health and how best to adapt to it. This change will move the clocks back by one hour, signaling the return to standard time and shorter daylight hours. But how does this seemingly simple act of changing the clocks affect your well-being?

What Is Daylight Saving Time in 2024?

Daylight saving time is a practice where clocks are set one hour ahead during the warmer months to maximize evening daylight. In 2024, the US will end its DST on November 3rd. With this change, we “gain” an extra hour of sleep but lose evening daylight earlier, which has both benefits and drawbacks.

How Does the End of Daylight Saving Time Impact Health?

1. Disruption to Circadian Rhythms: Does changing the clocks affect your internal body clock? Yes! Moving the clock back an hour can interfere with your circadian rhythms—the internal processes that regulate sleep and wake cycles. This sudden shift can lead to sleep disruptions, irritability, and even fatigue.
2. Increased Risk of Seasonal Affective Disorder (SAD):
   Could shorter days increase feelings of sadness? The reduction in daylight hours during fall and winter can increase the risk of developing seasonal affective disorder (SAD). This form of depression is often linked to the lack of sunlight, which plays a crucial role in regulating mood.
3. Potential Impact on Heart Health:
   Does this time shift pose a cardiovascular risk? Studies have shown that heart attack risk may increase during the switch to daylight saving time in spring, but there’s also evidence that returning to standard time may decrease this risk slightly, as people get more sleep initially. However, the overall impact on heart health remains mixed and individualized.
4. Mental Focus and Productivity:
   Does an extra hour of sleep boost productivity? While gaining an extra hour of sleep might sound beneficial, some people may find it hard to adjust to the time change, resulting in sluggishness during the day. Moreover, the earlier darkness can affect concentration, motivation, and general productivity, particularly in those sensitive to changes in daylight.

How Can You Prepare for the End of Daylight Saving Time in 2024?

1. Gradual Adjustment:
   Should you prepare your body for the change? Gradually adjusting your bedtime by 15-30 minutes in the week leading up to November 3rd can help your body adapt to the new schedule more smoothly.
2. Maximize Morning Sunlight:
   Could exposure to sunlight help your body adapt? Yes! Getting morning sunlight exposure can signal to your brain that it’s time to wake up, helping regulate your internal clock and reducing the negative impact of shorter daylight hours in the evenings.
3. Maintain a Consistent Sleep Schedule:
   Does consistency in sleep habits make a difference? Sticking to a regular sleep and wake schedule—going to bed and waking up at the same time daily—helps keep your circadian rhythms in balance, even during time changes.
4. Exercise and Eat Well:
   Can exercise help you adjust? Regular physical activity and a balanced diet can keep your energy levels stable and minimize the sluggishness that may come with the time change.

What Are Some Long-Term Effects of Daylight Saving Time?

Does the end of DST impact more than just sleep? Over time, some experts believe that the biannual clock changes may have subtle but meaningful effects on public health, including mental health challenges, disrupted work productivity, and even traffic accidents due to shifts in sleep patterns. With some advocating for permanent standard time, the debate continues about whether DST’s benefits outweigh its costs.

Is There a Push to End Daylight Saving Time Altogether in 2024?

In recent years, several US states have discussed moving to permanent daylight saving time or standard time. Some argue that this could eliminate the disruptions to health and sleep patterns, while others believe keeping DST year-round would help maintain longer evening daylight in the winter.

As the end of daylight saving time in 2024 approaches, preparing yourself both mentally and physically can ease the transition. By making small changes, like adjusting your sleep schedule and spending more time outdoors in natural light, you can minimize the effects of this biannual shift and stay healthy throughout the winter months.
