Workers Comp Accident Rates Affected By Spring Forward


Workers Comp Accident Rates Do Spring Forward

Do Workers Comp Accident Rates twice per year?  According to a recent article I came across- not necessarily.

The one hour time change in the fall has no effect on accident rates.   The springtime “ides of March” time change does lead to a higher rate of accidents.

Two doctoral candidates found that a spike in injuries does occur every March.

In two separate studies, they found that the March switch to Daylight Savings Time resulted in

  • 40 minutes less sleep for American workers
  • 5.7 percent increase in workplace injuries
  • nearly 68 percent more work days lost to injuries. 

In Canada, the accidents rate increases do agree with these two studies.   There was an 8% increase in accidents the Monday following the time change.

Traffic accidents do rise sharply on the Monday after the March Daylight Savings time change.  In fact, a long term study showed a 17% increase in traffic accidents on that Monday.

Finding any rating bureau information that is specific to a certain date each year was difficult at best.

A 2009 Journal of Applied Psychology study concluded that miners had a 40 minute sleep deprivation which resulted in a 5.7 increase in accident rates for the Monday after the March time change.   The Workers Comp accident rate for this one industry may not be reflective of all industries.
