Scientists Urge Ending Daylight Saving Time Due to Cancer, Accident, and Suicide Risks
Debate Over Daylight Saving Time: Health Risks vs. Economic Benefits
As clocks spring forward this Sunday, many dread losing an hour of sleep. Scientists are now urging an end to Daylight Saving Time (DST), linking it to increased risks of cancer, traffic accidents, and suicide. Dr. Eva Winnebeck and Dr. Vikki Revell, experts in sleep and circadian rhythms at the University of Surrey, warn that the shift disrupts sleep patterns and harms long-term health. “Sticking to Standard Time is crucial for our collective sleep and circadian health,” they argue.
The Case Against DST
Studies highlight immediate dangers post-time change: a 6% spike in fatal traffic accidents, higher cardiovascular events, and elevated suicide risks. Long-term, misalignment between body clocks and sunlight—exacerbated by DST—is tied to cancers like leukemia and breast cancer. Morning sunlight is vital for resetting our internal clocks, and DST reduces exposure during darker months. “Forcing earlier wake-ups in autumn means commuting in the dark, depriving us of essential morning light,” says Dr. Winnebeck.

Economic and Social Counterarguments
Not all oppose DST. Finn Burridge of the Royal Observatory Greenwich notes benefits: reduced energy demand due to evening daylight and boosted tourism and leisure activities. “Longer evenings encourage post-work economic activity,” he says. However, critics counter that energy savings are minimal in modern times, and health costs outweigh these perks.
Historical Context and Health Fallout
Introduced in 1916 to maximize productivity, DST shifts clocks forward in March and back in October. Yet, the British Sleep Society warns the practice disrupts sleep—a pillar of health. The abrupt change leaves populations fatigued, impacting judgment and productivity. Studies even suggest harsher judicial rulings and moral decision-making impairments post-transition.

The Science of Sunlight
Our bodies rely on morning light to sync with the 24-hour cycle. Regions farther west in time zones—where natural and social clocks misalign—see higher cancer rates, a risk mirrored under DST. Professor Malcolm von Schantz emphasizes, “Winter lacks spare daylight to ‘save.’ Morning light is scientifically proven to be more beneficial.”
Tradition vs. Health
While Burridge acknowledges health concerns, he cites tradition as DST’s main driver, with over 70 countries still practicing it. Yet, experts push for permanent Standard Time to prioritize well-being. “The first days after DST are the worst, but the long-term effects are even more alarming,” says Dr. Revell.

Conclusion
The debate continues, balancing tradition and economy against growing health evidence. As clocks change, the call to end DST grows louder, advocating for a timekeeping system that aligns with human biology.
