Research shows that daylight saving time can cause other health problems and disruptions apart from headaches. NPR published an article on the matter that said in the days following a time change, the country sees a higher incidence of car accidents, strokes, and heart attacks.

The semi-annual changing of the clocks is this Sunday when most of the country will "spring forward" into daylight saving time after more than four months in standard time. Why it matters: Lawmakers' attempts to get rid of the twice-yearly time changes and switch to permanent daylight saving time haven't gained traction.
