The safety of shoveling snow while pregnant depends on how much exertion it requires and how cold it is outside. The physical nature of shoveling snow can present a risk to pregnant women, especially ones at high risk of preterm labor.
According to Mayo Clinic, pregnant women should be cautious about activities such as standing for long periods of time, heavy lifting and exposure to extreme temperatures. Shoveling snow can involve great amounts of lifting, bending, standing, and exposure to cold weather, making it a risky activity for pregnant women. To offset these potential risks, Mayo advises wearing proper footwear while standing, and lifting with the proper form so that the legs, not the back, carry the load.
