    Research has also shown a spike in car crashes following daylight saving time changes.

    In a study being published in American Economic Journal next month, Smith analyzed vehicle accidents just before and after daylight saving time in the U.S. over a 10-year period. The results showed a 6 percent increase in crashes immediately after people reset their clocks in the spring, which amounted to more than 300 deaths.
