Daylight Saving Time (DST) has proven to have significant negative effects on health, particularly for endurance athletes, according to a recent study from the American Academy of Sleep Medicine. With the upcoming shift on March 9, 2025, most of the country will lose an hour of sleep as clocks spring forward at 2 a.m., triggering discussions about the benefits and drawbacks of this time change. For some, the longer days encourage evening workouts, while others struggle to adjust, particularly morning runners who lose sunlight and sleep in the early hours.
The Cleveland Clinic highlights that endurance athletes face the harshest consequences of sleep deprivation caused by DST. A sleep expert notes that losing an hour results in increased fatigue and decreased motivation, creating additional challenges for those training for longer distances. The American Academy of Sleep Medicine emphasises that DST disrupts our circadian rhythms and can have lasting negative health impacts, advocating for the elimination of seasonal time changes.
One primary concern of DST relates to how it misaligns with the body’s internal clock. Dr. Steven Zorn explains that light influences circadian rhythms, and post-DST, the body can take weeks to readjust, causing disturbances in hormone regulation and sleep quality. He advises that the existing model—switching clocks—complicates and impairs the sleep schedules of many.
To mitigate the effects of DST, Dr. Zorn suggests allowing around one to two weeks for full adjustment. He advises endurance runners to reduce workout intensity but maintain a regular sleep schedule. Sticking to consistent sleep patterns can help improve overall sleep efficacy and wellbeing. So while the allure of longer evenings beckons, it’s vital to still prioritise restorative rest, to perform at your best without burning the midnight oil.
Daylight Saving Time (DST), starting March 9, 2025, adversely affects endurance athletes by disrupting sleep and motivation. The American Academy of Sleep Medicine warns of potential health risks and advocates for abolishing seasonal time changes. Sleep expert Dr. Steven Zorn notes that circadian rhythms take time to adjust post-DST, indicating a need for stable sleeping patterns. To cope, athletes should reduce training intensity but maintain regular sleep schedules.
In conclusion, Daylight Saving Time poses considerable challenges for endurance athletes, leading to sleep deprivation, increased fatigue, and decreased motivation. The American Academy of Sleep Medicine and experts like Dr. Steven Zorn stress the need for a stable time system aligned with natural body rhythms. Adjusting to DST can take weeks, but maintaining consistent sleep schedules is essential for optimal health and performance. As longer evenings approach, prioritising rest remains crucial for athletes’ success.
