The Wirecutter Show: How to Survive Daylight Saving Time Release Date: March 4, 2025

Introduction In this special bonus episode of The Wirecutter Show, hosted by Rosie Guerin and co-hosted by Kyra Blackwell, the team delves into the annual challenge of adjusting to Daylight Saving Time (DST). With the upcoming shift on March 9th, the hosts explore the implications of "springing forward" and provide expert advice on mitigating the negative effects associated with this time change.

Understanding Daylight Saving Time Rosie introduces the topic by highlighting that DST begins on March 9th, lasting until November, during which clocks are set forward by one hour. While often perceived as minor inconveniences, DST has more profound impacts on our health and daily routines.

Kyra’s Insights on Circadian Rhythms Kyra explains the biological disruptions caused by the one-hour shift:

"Studies have shown that even something as slight as a one-hour time shift can disrupt our circadian rhythms, which is basically just our body's internal 24-hour clock that follows the sun." [02:48]

This misalignment between the social clock and the body’s internal clock can result in jet lag-like symptoms, including difficulty falling asleep or waking up, and an increase in health risks such as car accidents, heart attacks, and strokes during the transition period.

The Origins and Criticism of DST The conversation shifts to the rationale behind DST. Contrary to popular belief, Kyra debunks the myth that farmers benefit from DST:

"Farmers actually notoriously hate daylight saving because it's completely opposed to their schedules, which follows the sun..." [04:10]

Instead, DST primarily benefits large corporations, including gas companies and retail sectors, by extending evening daylight and encouraging consumer spending. This shift results in approximately eight months of DST compared to 4.5 months of Standard Time, despite evidence suggesting that Standard Time is more aligned with human health and safety.

Health Implications of DST Kyra emphasizes that Standard Time is the optimal choice for health and safety:

"A 2024 study found that standard time, which is what we're leaving right now to enter Daylight saving time, is the optimal choice for health and for safety following the sun’s clock." [04:56]

The extended period in DST exacerbates the negative health impacts, making it more than just a minor inconvenience for many individuals.

Strategies to Adjust to DST Kyra offers practical advice to help listeners adapt to the time shift smoothly:

1. Gradual Sleep Schedule Adjustment Begin shifting your bedtime earlier in small increments:

   "Start shifting in 15-minute increments starting on Wednesday, so your body is ready to sleep by 9pm that Saturday before the time switch happens." [05:22]

2. Maintain Consistent Eating Schedules Align meal times with the new sleep schedule to prevent digestion from interfering with sleep:

   "If you're going to be going to sleep earlier, that means you need to eat a little bit earlier." [05:22]

3. Limit Stimulants Before Bed Avoid caffeine and alcohol at least six hours before bedtime to promote better sleep quality:

   "Don't do things like drink caffeine or alcohol before going to bed, especially caffeine." [05:22]

4. Optimize Bedroom Temperature Maintain a cool environment to signal your body that it's time to sleep:

   "The optimal sleep temperature is between 60 and 67 degrees Fahrenheit." [06:45]

5. Regulate Light Exposure

   • Evening: Reduce exposure to bright lights to encourage melatonin production.
   • Morning: Increase sunlight exposure to reset the body’s internal clock.

   "Kill as much light as possible in the early evenings... get as much sunlight as possible as soon as possible in the morning." [06:54]

   Solutions include using blackout curtains or eye masks in the evening and utilizing sunrise alarm clocks to simulate natural light in the morning:

   "Use a sunrise alarm clock to basically simulate warm sunlight in your room when you're waking up in the morning." [08:58]

6. Enhance Morning Activity Engage in physical activities like running or yoga to boost alertness and signal the start of the day:

   "Do something active, that is the best thing you can do for your body during this time." [09:34]

Conclusion Kyra encapsulates the essence of adjusting to DST with a simple yet effective mantra:

"Light, light, light. Block it at night, get it in the morning." [10:20]

The episode wraps up with Rosie thanking Kyra for her insightful tips and hinting at future topics, such as vacuums. Listeners are encouraged to visit the Wirecutter website for more detailed product recommendations and coverage related to DST.
