What are the health risks associated with changing the clocks?
Changing the clocks for Daylight Saving Time can disrupt our circadian rhythms, leading to sleep disturbances. Studies have shown that this disruption can increase the risk of heart attacks and strokes, particularly in the days following the time change. The British Sleep Society emphasizes the importance of maintaining a consistent sleep schedule to mitigate these risks.

Why do experts advocate for permanent Greenwich Mean Time?
Many health experts argue for a permanent standard time, such as Greenwich Mean Time (GMT), to avoid the biannual disruption caused by DST. They believe that a consistent time would help stabilize sleep patterns and reduce the associated health risks, including cardiovascular issues and mental health problems linked to seasonal affective disorder.

What are the arguments for and against daylight saving time?

What historical context surrounds daylight saving time?
Daylight Saving Time was first proposed by Benjamin Franklin in 1784 but wasn't implemented until the Uniform Time Act of 1966. The current system, which began in 2007, mandates a time change twice a year. While some appreciate the extra hour of daylight in the evening, others suffer from the darker mornings and the health implications that come with the clock change.
