Bed rest might not be the best course of action for women dealing with a difficult pregnancy, according to some new research.

FOX's Colleen Cappon reports in today's "Housecall for Health":

New research suggests the age-old treatment for troubled pregnancies, bed rest, could be harmful.

A study from the NIH of more than 600 women, showed nearly 40% of women who cut activity had a premature baby, compared to just 17% in women who didn't scale back.

Researchers say bed rest increases the risk of blot clots, bone loss, and muscle loss.  And there are better treatments to prevent pre-maturity.
