Electric blankets can be a great source of warmth and comfort, but are they safe to use during pregnancy? Electric blankets emit a low-frequency electromagnetic field (EMF) and can cause the body temperature to rise beyond 102°F (38.9°C). While the World Health Organization (WHO) has stated that current evidence does not show that exposure to EMFs causes health problems, some studies have indicated a potential link between electric blanket use and adverse effects on pregnancy and fetal development, including an increased risk of miscarriage and congenital urinary tract anomalies (CUTAs). Therefore, it is recommended to exercise caution and consult a healthcare professional before using an electric blanket during pregnancy, especially during early pregnancy and late pregnancy.

What You'll Learn

Electric blankets and the risk of miscarriage
Electric blankets emit electromagnetic fields (EMFs) and non-ionizing radiation. Research shows that exposure to non-ionizing radiation may increase the chance of pregnancy loss. A study found that using an electric blanket during conception and early pregnancy may be associated with a slightly increased risk of miscarriage. However, the same study found no increased risk with electric blanket use between 8 to 16 weeks of pregnancy.
The World Health Organization (WHO) has found that current evidence does not show that exposure to electromagnetic fields causes any health problems. The WHO also stated that overall evidence shows that typical exposure to electromagnetic fields, including when using an electrically heated blanket, does not cause miscarriage, birth defects, low birth weight, or disease.
However, it is important to note that raising your core body temperature to over 101 degrees Fahrenheit can be dangerous for your developing baby. Therefore, it is recommended to use electric blankets at a controlled temperature and avoid using them for too long or at high settings. To avoid overheating, use the electric blanket on its low or medium setting and turn it off before going to bed.
Additionally, electric blankets may pose a risk of burn injuries and fires if the recommended precautions are not followed. It is important to regularly check for wear and tear, avoid crimped wires, and follow the manufacturer's guidelines.
Pregnant women should consult their doctors before using electric blankets and consider their pregnancy stage, associated conditions, and overall health.

The impact of electric blankets on fertility
Electric blankets emit electromagnetic fields (EMFs) and non-ionizing radiation. While the World Health Organization (WHO) has found that current evidence does not show that exposure to EMFs causes any health problems, some studies have indicated that the use of electric blankets during conception and early pregnancy may be linked to an increased risk of miscarriage and congenital urinary tract anomalies, particularly in women with a history of subfertility.
One study found that the miscarriage rate in the high exposure group was twice that of the low exposure group. Another study found that the risk of congenital urinary tract anomalies was more than four times higher among women with a history of subfertility who used electric blankets during pregnancy, with the risk being even greater if the exposure occurred during the first trimester.
It is important to note that the evidence on the impact of electric blankets on fertility is mixed, and the WHO has stated that overall, the evidence does not confirm that sources of environmental electromagnetic fields increase the risk of pregnancy complications. However, they have highlighted the need for further research.
To minimize any potential risks, it is recommended that individuals use electric blankets at low temperatures and for pre-warming the bed rather than sleeping under it for prolonged periods. Additionally, individuals with circulation issues should use electric blankets with caution, as they may be less sensitive to heat levels and could potentially sustain burns.

How to safely use electric blankets during pregnancy
Pregnancy is a delicate time, and it is important to take precautions to ensure the health and safety of both mother and baby. While electric blankets can be a convenient way to stay warm, there are some potential risks associated with their use during pregnancy that should be carefully considered. Here are some guidelines on how to safely use electric blankets during pregnancy:
Consult Your Doctor
Before using an electric blanket during pregnancy, it is essential to consult your doctor or healthcare provider. They can advise you based on your individual health, pregnancy history, and any associated conditions. Your doctor can help you weigh the benefits against the risks and make an informed decision.
Understand the Risks
Research suggests that electric blankets may pose certain risks during pregnancy. Some studies indicate a possible association between electric blanket use and an increased risk of miscarriage, particularly during conception and early pregnancy. Additionally, there are concerns about the potential impact on the developing fetus, including congenital urinary tract anomalies and fetal abnormalities.
Control the Temperature
To minimise risks, it is crucial to control the temperature of your electric blanket. Keep the temperature setting low or medium, regardless of your pregnancy stage. Ensure your core body temperature does not rise above 101°Fahrenheit (38.9°Celsius). Using the electric blanket to pre-warm your bed and then turning it off before getting in is a safer approach.
Be Mindful of Duration
Avoid using the electric blanket for extended periods. Prolonged use may increase the risk of overheating, which can lead to dehydration and other complications. Do not fall asleep with the electric blanket on. If you feel yourself getting too hot, take a break and allow your body to cool down.
Practice Safe Usage
Always follow the manufacturer's guidelines and safety warnings. Regularly inspect your electric blanket for any wear and tear, paying close attention to the wires. Avoid folding or sitting/lying on the electric blanket, as this can damage the internal coils and increase the risk of burns. Make sure to store it properly when not in use, rolling it up gently or hanging it to avoid wire damage.
Explore Alternatives
If you are concerned about the risks, consider alternative ways to stay warm. Layering up with regular blankets, wearing warm clothing, or using hot water bottles can provide warmth without the same level of risk. Remember to consult your doctor if you have any doubts or concerns about your specific situation.

Electric blankets and congenital urinary tract anomalies
Electric blankets emit electromagnetic fields (EMFs) and non-ionizing radiation. While the World Health Organization (WHO) has stated that the evidence does not show that exposure to electromagnetic fields causes health problems, some studies have indicated that there may be adverse effects for pregnant women.
One study found that using an electric blanket during conception and early pregnancy may be associated with a slightly increased risk of miscarriage, but no increased risk was found between 8 to 16 weeks of pregnancy. The risk of miscarriage was also found to be higher in those with higher exposure to non-ionizing radiation.
Another study found that prenatal use of electric blankets was associated with a more than four-fold increase in the risk of congenital urinary tract anomalies (CUTAs) among women with a history of subfertility. The risk was even greater if the exposure occurred during the first trimester. However, among all subjects, the risk of CUTAs was not found to be materially associated with prenatal exposure to electric blankets.
To minimize the risks associated with electric blankets, it is recommended to use them on low or medium settings and for a short duration to avoid raising the core body temperature beyond 101°Fahrenheit (38.9°Celsius). It is also suggested to use the electric blanket to pre-warm the bed and then turn it off before getting into bed.

Alternatives to electric blankets during pregnancy
There is conflicting evidence about the safety of using electric blankets during pregnancy. While some studies have found that electric blankets may increase the risk of miscarriage, congenital urinary tract anomalies, and fetal neural tube defects, other studies have found no increased risk. Due to these potential risks, it is recommended that pregnant women consider alternative ways to keep warm.
One alternative to using an electric blanket is to use a hot water bottle or a modern microwavable heating pad to heat up the inside of the blanket. These provide targeted warmth and are easy to use. Another option is to use a heated mattress pad, which provides consistent warmth without the potential risks associated with the elevated settings of some electric blankets.
To stay warm in bed without using an electric blanket, you can also try layering up with warm clothing, such as a warming nightcap, socks, and thermal innerwear. Using brushed fabrics, such as flannel, for bedsheets can also help as the texture traps air and acts as an insulator. Creating layers using duvets and thick blankets can provide extra insulation, trapping air to keep you warm.
If you are considering using an electric blanket, it is important to take precautions to avoid overheating. Do not use the blanket for too long, and avoid high settings. Avoid falling asleep with the electric blanket on, and turn it off before going to sleep. It is also recommended to consult with a doctor before using an electric blanket during pregnancy.
