Some Pa. lawmakers want to end daylight saving time, but impacts are uncertain

Pennsylvania lawmakers are considering three bills related to daylight saving time. Experts testified that ending the time change could improve sleep and health. Dr. Indira Gurubhagavatula, a University of Pennsylvania professor, said data shows Americans are chronically sleep deprived and that losing an hour of sleep each spring is significant. Changing clocks disrupts the body's internal clock and can lead to serious health problems, including heart attacks and depression. The committee is weighing the potential impacts on routines such as agricultural work and youth sports. Rep. David Delloso, the committee chairman, said the issue requires further discussion.
