For pregnant women, modest execise may be good, but a study from the School of Public Health at the University of California at Berkeley says standing for long hours may not be. Women with a history of miscarrige who stand for more than seven hours a day have a 2-3 fold greater risk of miscarrige. At greatest risk are nurese, bank tellers, and factory workers. The sutdy recommends frequenr rest breaks. No connection was found between miscarriages and lifting weights. Future studies will focus on the effect of workplace stress on pregnancy.
