The U.S. House of Representatives passed the Sunshine Protection Act on July 14, which would make daylight saving time permanent across the country. The bill, sponsored by Florida Rep. Vern Buchanan, aims to eliminate the biannual clock change that occurs in March and November.

Concerns from Sleep Experts

However, sleep experts, including Wendy Troxel, Ph.D., have expressed concerns about the potential negative impact of permanent daylight saving time on public health. Troxel notes that the human body’s internal clock, or circadian rhythm, is better aligned with standard time, and that permanent daylight saving time could lead to less morning light and more sunlight later in the day, negatively impacting sleep.

Research has shown that the biannual clock change can have negative effects on health, including increased risk of car accidents and heart attacks. However, some studies suggest that permanent standard time may be better for public health, as it allows for more morning light and aligns with the body’s natural circadian rhythm.

State Opt-Out Provision

The Sunshine Protection Act includes a provision that allows states to opt out of the permanent daylight saving time setup before it goes into effect. This means that individual states can choose to maintain their current clock change schedule if they so desire.

The bill’s future is uncertain, as it still needs to pass through the Senate. Arkansas Sen. Tom Cotton has expressed opposition to the bill, citing concerns about the potential impact on morning sunshine and public safety.
