Marco Rubio, R-Fla., said Tuesday that he and fellow Florida Republican Sen. Rick Scott as well as bipartisan colleagues from Oklahoma, Missouri, Rhode Island, Oregon, Mississippi and Massachusetts have reintroduced the Sunshine Protection Act in an effort to make daylight saving time permanent across the U.S.A bill to allow Florida to remain on daylight saving time year-round was signed into law in 2018, but for Florida’s change to apply, the federal statute must be changed, Rubio said.“Fifteen other states — Arkansas, Alabama, California, Delaware, Georgia, Idaho, Louisiana, Maine, Ohio, Oregon, South Carolina, Tennessee, Utah, Washington, and Wyoming — have passed similar laws, resolutions or voter initiatives, and dozens more are looking,” Rubio said in a statement.Rubio’s statement said the change could bring improvements, including shrinking seasonal depression, reducing car accidents by better aligning daylight hours with commuting times, cutting down on robberies by adding more daylight hours and lowering childhood obesity by adding more time for physical fitness.Sen. Ed Markey, D-Mass., added in the statement, “Studies have found year-round Daylight Saving Time would improve public health, public safety, and mental health — especially important during this cold and dark COVID winter.”“I am now proud to sponsor the Sunshine Protection Act to add an extra hour of sunshine for the full 365 days a year,” Markey said.What is daylight saving time?It was invented to make the best use of daylight hours.
