Springing Forward, may be left in the past! With lawmakers recently pushing toward permanent daylight savings time, we spoke with one of our sleep medicine providers, Dr. Saurav Luthra, on what this change could mean for our sleep and health.
Q: How does the current biannual daylight saving schedule affect sleep health?
- Dr. Luthra: The twice-yearly time changes disrupt our circadian rhythm, leading to poorer sleep quality, increased daytime sleepiness, and reduced alertness for several days after the transition. The spring shift, in particular, has been associated with increases in motor vehicle accidents, cardiovascular events, and workplace injuries due to acute sleep loss.
Q: What is your reaction to the U.S. House passing legislation that would establish permanent daylight saving time?
- Dr. Luthra: While eliminating the twice-yearly clock changes is a positive goal, permanent daylight saving time is not the ideal solution from a health perspective. It would result in darker mornings for much of the year, especially during winter, which can negatively affect sleep, alertness, and circadian alignment.
Q: Can you discuss why permanent Standard Time may be preferred over permanent daylight saving time from a sleep medicine perspective?
- Dr. Luthra: Permanent Standard Time is more closely aligned with the body's natural circadian rhythm because it better matches the timing of sunrise and natural light exposure. Morning sunlight is the strongest cue for regulating our internal clock, promoting healthier sleep, improved daytime alertness, and better overall physical and mental health. It is especially beneficial for children and adolescents, as we want them traveling to school and starting their day with natural morning light rather than in darkness. Morning light supports healthy circadian rhythms, improves alertness and learning, and may enhance safety during the morning commute.
