Daylight savings increases job injuries

September 10, 2009 (CHICAGO) A new study finds on the day we lose an hour of clock time, people lose about 40 minutes of sleep, and that appears to result in an increase in injuries.

The study in the Journal of Applied Psychology found on Mondays after the time switch, there was an almost 6 percent increase in injuries and a 68 precent increase in lost work days.

On the other hand, falling back, or gaining an hour, had no affect on sleep duration.
