On July 14, 2026, the U.S. House voted 308-117 to approve the Sunshine Protection Act (H.R. 139), which would make Daylight Saving Time (DST) permanent nationwide, ending the twice-yearly clock changes.  Sponsored by Rep. Vern Buchanan (R-FL) with support from President Trump, the bill now heads to the Senate. States could opt out. 

Iowa lawmakers have long backed permanent DST through state bills, reflecting frustration with clock adjustments. 

Effects on Daily Life in Iowa

•  Mornings: Winter sunrises in Des Moines would shift from ~7:30 a.m. to ~8:30 a.m. (later farther west), leading to darker commutes and school bus waits. This raises safety concerns for children and drivers. 

•  Evenings: Extra daylight for after-work activities, sports, and family time year-round, with winter sunsets delayed by an hour. 

•  Agriculture: Farmers, who follow solar time, may face darker early mornings for chores despite artificial lighting. Livestock routines remain unchanged. 

•  Health & Sleep: Ending transitions reduces short-term disruptions (e.g., heart risks, accidents), but permanent DST may misalign with natural circadian rhythms, potentially worsening long-term sleep, mood, and health compared to standard time. 

•  Economy & Energy: Possible boosts to evening retail/recreation; energy savings are minimal or debated. 

Pros: Convenience, more evening light, economic activity.

Cons: Darker winter mornings, health alignment issues, impacts on schools and farms.

Public opinion in Iowa and nationally favors ending clock changes, with many preferring permanent DST for evening light, though sleep experts often recommend standard time.
