Microwaves work by using electromagnetic radiation to raise the temperature of water molecules in food, which generates electromagnetic fields (EMFs). Other sources of EMFs include cell phones and other electronics. There has been concern and debate over EMF exposure during pregnancy, and that EMFs may cause low birth weight or birth defects. However, there is simply not enough research on humans that has shown a direct connection between microwave EMFs and birth abnormalities. While one study in 2016 observed that significant and prolonged exposure to EMFs could pose a risk of miscarriage during pregnancy, the researchers concluded that further study on larger samples was still needed.

Safely Using a Microwave in Pregnancy

To ensure your safety when using a microwave when pregnant or not, be sure that your microwave does not leak. Most recently made microwaves will not work if the seal on the door is broken, so newer microwaves tend to be safer. Some experts suggest that if you are concerned, simply put your food in the microwave and walk away while it’s cooking to avoid the potential exposure to EMFs. However, most experts will tell you that it is safe to use the microwave during all three trimesters of pregnancy.

Microwave Food Safety

Use proper food safety rules when cooking and heating with the microwave. Some plastics can melt or warp in the microwave, this can cause chemicals to leach into your food. You should always use the microwave with approved food containers, like glass and specific plastics to avoid this risk. Be sure that whatever you are making in the microwave is cooked long enough to be warmed appropriately, but not overdone. Once cooked, allow it to cool sufficiently. When appropriate, stir the food to make sure the temperature is even. Consider using oven mitts to remove bowls and dishes from the microwave to avoid burns. When lifting lids, do so away from your body to prevent steam burns from the released steam. These may all sound like common sense, but it’s easy to take microwave food safety for granted.

A Word From Verywell

When in doubt, remember that you can also go the slightly slower and more traditional route of using the oven or stovetop to cook your food. Be sure that you follow food safety rules to prevent food poisoning and burns.
