Congress Is Choosing Artificial Time Over Human Health
Congress claims it wants to stop Americans from changing their clocks. That part makes sense. The issue is what lawmakers decided to replace it with.
On July 14, 2026, the U.S. House passed the Sunshine Protection Act with a 308-117 vote, promoting permanent daylight saving time instead of permanent standard time. The bill now moves to the Senate and is not yet law. If passed, winter sunrises would happen one hour later by the clock. Washington would not create any extra minutes of daylight. It would only rename the morning, forcing schools, workplaces, and families to operate one hour later. Some communities could see winter sunrises as late as 9 a.m.
That is artificial time, created by legislation.
Doctors Favor the Time Nature Already Gives Us
The medical case is quite clear. In an official position statement, the American Academy of Sleep Medicine called for fixed, year-round standard time because standard time matches human circadian biology better. Morning light helps set the brain’s internal clock, supports alertness after waking, and allows the sleep hormone melatonin to rise at a more suitable time at night.
The American Medical Association reached the same conclusion. AMA Trustee Dr. Alexander Ding warned that the country has focused on later evening daylight while accepting public health and safety risks. He argued that permanent standard time would resolve the conflict between people’s biological clocks and their alarm clocks.
Permanent daylight saving time does the opposite. It makes sunrise happen an hour later according to the clock, while extra evening light leads people to stay awake longer. Congress can change what time appears on a clock, but it cannot force the human nervous system to ignore sunlight.
A 2025 analysis led by Stanford compared permanent standard time, permanent daylight saving time, and the current clock-switching system. Researchers found that permanent standard time caused the lowest expected circadian burden and greater estimated reductions in obesity and stroke compared to permanent daylight saving time. Though the findings depend on modeling assumptions, they support what sleep doctors have insisted for years: morning light matters.
The Health Risks Are Not a Talking Point
The clearest evidence of immediate harm comes from the spring shift to daylight saving time. A study published in Current Biology examined over two decades of U.S. fatal crash records. Researchers found about a 6 percent increase in fatal motor vehicle crashes during the workweek after the spring time change. The increase was particularly noticeable in the morning and in the western parts of time zones.
The American Heart Association has also pointed out studies suggesting more heart attacks and strokes following the spring change. Doctors believe that the sudden mix of lost sleep and circadian disruption may worsen blood pressure, inflammation, and cardiovascular stress in at-risk individuals.
These studies don’t prove that every day under permanent daylight saving time would cause the same short-term spike. They do show that shifting social schedules away from natural solar time can have real effects.
Permanent standard time would remove the disruptive clock change without locking the country into darker winter mornings. That is the medically responsible solution.
Children and Workers Should Not Begin the Day in Darkness
With permanent daylight saving time, children in many northern and western areas could wait for buses or walk to school before sunrise for weeks or months. Some locations might see winter sunrises around or after 9 a.m.
America already tried this. Congress imposed year-round daylight saving time in January 1974 during the energy crisis. Public support dropped sharply after families dealt with dark winter mornings, leading lawmakers to end the experiment early. Concerns about children traveling to school in darkness sparked a public backlash.
Construction crews, commuters, and agricultural workers would face similar issues. Farmers do not gain more daylight because of clock changes. Crops, morning dew, and livestock still depend on the sun. Farmers have historically opposed daylight saving time because commercial schedules changed while natural conditions stayed the same. The initial push for daylight saving time mainly came from industrial and commercial interests, not farmers.
Business Gets the Evening, the Public Gets the Risk
Supporters openly promote more evening shopping, tourism, golf, recreation, and economic activity. While those may be appealing commercial benefits, they are not medical proof. Daylight saving time has long received support from retail, tourism, and leisure industries because evening sunlight encourages people to stay outside and spend money.
This history is important. The House chose the option that provides businesses with a longer evening sales window, even though major medical organizations recommend permanent standard time.
This is government control in the most literal sense. Lawmakers can’t move the sun, so they change the legal clock and expect everyone else to adjust their lives accordingly.
Ending the clock changes makes sense. Making permanent daylight saving time the national default does not.
The Senate should reject artificial time and choose permanent standard time. Public policy should reflect human biology, not the cash register.
