A pregnant woman should avoid standing more than four or five hours at a time without frequent breaks to rest, says Michigan Based OB/GYN Donna Harrison. For some women, especially those more than 24 weeks pregnant, significant time on your feet could cause risk for preterm labor, warns Harrison. Listen to your body to determine the amount of time you can tolerate standing on your feet at work while pregnant. If you are experiencing painful leg swelling or are having Braxton Hicks contractions more than four times each hour, you may need to lay down, drink some fluids and elevate your legs, she notes.
Especially in the last five weeks of pregnancy, many women find that continuous work while standing becomes much more difficult. “Don't forget that pregnancy is hard work, and you are nourishing a very active human being inside, so you need to give yourself extra time for rest and sleep,” Harrison advises.
