# The Unnecessary Burden of Daylight Saving Time and Its Impact
Written on
Chapter 1: Understanding Daylight Saving Time
The concept of “springing forward” has become a yearly ritual for many Americans, yet this practice of Daylight Saving Time (DST) raises questions about its necessity. While we recently enjoyed an extra day due to Leap Day, on March 10, most Americans will lose an hour when they adjust their clocks, marking the end of Standard Time and the beginning of DST.
This practice is flawed from a practical perspective, failing to achieve its intended objectives and posing threats to individual health and public safety. Surprisingly, many countries have opted out of this time change altogether.
In Europe, most nations transition to DST on the last Sunday of March, but only Egypt in Africa adheres to this custom. The majority of Asian countries do not observe it, and while some regions in Canada do, Mexico has discontinued the practice.
Section 1.1: Historical Context of DST
The origins of Daylight Saving Time in the United States date back to 1918, when it was introduced as a measure to conserve fuel during World War I. The Standard Time Act established the time zones we are familiar with today and initiated the practice of moving clocks forward. The government marketed this change as a way to enjoy an “extra hour of sunlight.”
After the war, the practice was abandoned but was reinstated during World War II. Following that conflict, states were given the option to continue observing DST or revert to Standard Time. Over the decades, the system has undergone multiple adjustments, notably in the mid-1960s, mid-1970s (due to the oil embargo), the mid-1980s, and most recently in 2007.
Today, DST begins on the second Sunday in March and concludes on the first Sunday in November, with clocks springing forward and falling back at 2 a.m. Not all Americans are affected, however, as some states and territories have chosen to remain on Standard Time year-round. This includes American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, the U.S. Virgin Islands, Hawaii, and Arizona (excluding the Navajo Nation, which observes DST).
Section 1.2: The Case Against Daylight Saving Time
Research indicates that DST may not be as beneficial as originally thought. Numerous studies have cast doubt on its effectiveness in conserving energy, the primary goal of its implementation. Additionally, the transition into DST has been linked to various health and safety concerns:
- A 6% spike in auto accidents during the week following the start of DST.
- Decreased worker productivity and increased workplace injuries.
- A reported 24% rise in heart attacks on the first Monday after the clock change, although some studies have challenged this correlation.
There are suggestions that the clock change may even be associated with an elevated risk of certain cancers, including breast cancer, though the evidence is less conclusive. Much of these health issues stem from the disruption of sleep patterns that occur during the transition.
Beth Ann Malow, MD, a neurology and pediatrics professor at Vanderbilt University, notes, “It’s become clear to me and many of my colleagues that the transition to Daylight Saving Time each spring affects health immediately after the clock change and also for the nearly eight months that Americans remain on Daylight Saving Time.”
Subsection 1.2.1: The Importance of Morning Light
Morning sunlight plays a crucial role in regulating our internal body clocks. According to Malow, “Morning light is essential for helping to set the body’s natural rhythms: It wakes us up and improves alertness.” This disruption caused by DST can lead to negative impacts on our overall well-being.
Jennifer Martin, PhD, president of the American Academy of Sleep Medicine, explains that “Daylight Saving Time disrupts the body’s natural circadian rhythms and impacts sleep.” Standard Time, on the other hand, allows for a more consistent and restorative sleep pattern, which is vital for cognitive function, mood stability, cardiovascular health, and general wellness.
Chapter 2: The Future of Time Management
As calls for a permanent switch to Standard Time grow louder, changes seem unlikely without congressional action. In 2022, a bill proposing permanent DST was passed by the Senate but subsequently stalled in the House of Representatives, leaving many to wonder when or if any changes will be made. While some states have expressed interest in maintaining Standard Time, they face hurdles without federal approval.
In anticipation of the transition into DST, sleep specialists recommend gradually adjusting sleep schedules in the days leading up to the change. A detailed plan to manage this shift was shared in a prior article.
Overall, adopting healthy sleep habits can help mitigate the effects of losing that hour. Here are some additional resources on sleep health:
