Warm legs, healthy pregnancy? new study tests heat therapy for Moms-to-Be

This study tests whether regularly warming the legs with a portable sauna blanket can improve blood vessel health and lower the risk of high blood pressure disorders in pregnant women with obesity. About 118 women will use the blanket at home for 16 weeks, starting early in pregnancy. Researchers will measure changes in blood vessel function and nerve activity to see if this simple, drug-free approach works.
