“The Senate unanimously approved a measure Tuesday that would make daylight saving time permanent across the United States next year. The bipartisan bill, named the Sunshine Protection Act, would ensure Americans would no longer have to change their clocks twice a year.” AP News

Many on both sides agree that clocks should not be changed twice a year, regardless of whether the switch is to standard or daylight time:

“Although saving energy was often put out as a reason to have Daylight Saving Time, the energy saved isn't much -- if anything at all. Instead, the lobbying effort for Daylight Saving Time came mostly from different sectors of the economy. In the mid-20th century, lobby groups for the recreational sports industry (think driving ranges) wanted more customers to come out after a day at the office. It's easier to do so when there is more light at the end of the day. But the movie industry didn't like Daylight Saving Time. You're less likely to go to a movie when it's bright outside. Despite the myth, farmers didn't like it either because it made it difficult to get their food to the market in the morning… It just depends on who you are and what you want. You can make an argument either way.”

“Recent polls show that 63% of Americans want to get rid of altering the clock altogether… The reason for the changing clock has lost its significance. Studies have shown that there is little in the way of energy savings from flipping the clock, nor is there a bump in economic activity… The Uniform Time Act in 1966 established start and end dates for Daylight Saving Time. When you consider that America is a continental country with four time zones in the contiguous United States, some kind of standardization is necessary.”

“Sleep scientists continually advocate that, for optimal health, people should stick to the same sleep schedule every night, going to bed and waking at the same hours each day. When we shift clocks forward one hour in the spring, many of us will lose that hour of sleep. In the days after daylight saving time starts, our biological clocks are a little bit off. It’s like the whole country has been given an hour of jet lag…

“One hour of lost sleep sounds like a small change, but we humans are fragile, sensitive animals. Jet lag can mess with our metabolism; extreme versions of it can contribute to diabetes or obesity. But in the short term, jet lag dulls our mental edge… Being an hour off schedule means our bodies are not prepared for our actions at any time of the day.”

“Any change to our ‘body clock,’ can result in severe health problems such as a higher incidence of heart attacks. These negative health consequences were verified in a 2008 study conducted by the New England Journal of Medicine, which identified an increase in heart attacks in the three days following the implementation of daylight-saving time… In 2020, exhaustive research by professors at the University of Colorado at Boulder determined that there is a 6% increase in fatal automobile accidents in the week following the switch to daylight-saving time…

“[A 2009 study] noted that daylight-saving time led to not only a loss of sleep, but also additional workplace injuries. Along with heart attacks, accidents and workplace injuries, there is undoubtedly a loss of work productivity that also accompanies losing an hour of sleep. The deaths, injuries and lack of productivity are totally unnecessary.”
