Should we switch to permanent standard time?

How does ending daylight saving time affect health and sleep?
Ending daylight saving time and returning to standard time can help improve sleep quality, reduce fatigue, and lower health risks like heart disease. The clock change disrupts our internal body clocks, but sticking to standard time year-round may minimize these negative effects.
