Electric blankets are a popular way to keep warm during cold winter nights. They are a great way to save on heating bills and can be very cosy. However, there are several safety concerns associated with their use. The most common issue is the risk of fire due to faulty wiring or overheating. Electric blankets can also pose a risk of burns, especially for those with circulation issues or altered sensation, who may not feel the heat accurately. There are also concerns about the electromagnetic fields (EMFs) emitted by electric blankets, which some researchers speculate may be linked to cancer, pregnancy loss, and decreased fertility. While modern electric blankets have improved safety features such as automatic shut-off, it is important to follow manufacturer guidelines and safety precautions to minimise potential risks.

What You'll Learn
Electric blankets emit EMFs, which may be harmful
Electric blankets emit electromagnetic fields (EMFs), which may be harmful. While there is no conclusive evidence, EMFs have been linked to cancer, fertility issues, and pregnancy risks. Research by Dr Desiderio Avila at Phoenix’s Ironwood Urology found that radiation from electric blankets can damage both male and female reproductive cells. Avila also found that the radiation emitted by electric blankets can reach "70,000 times acceptable levels".
EMFs are emitted by all electrical appliances, and scientists disagree on how harmful they are. However, it is generally advised to avoid placing EMF-emitting devices in the bedroom, especially on top of your body for extended periods. Electric blankets could therefore be a particular cause for concern, given their direct contact with the body.
To minimise the risks, it is recommended to use electric blankets cautiously and follow manufacturer guidelines. For example, some advise turning on the electric blanket an hour or so before bed, and turning it off before getting into bed. This ensures a warm start to the night, without the need for the blanket during sleep.
It is also important to regularly check electric blankets for wear and tear, especially crimped or frayed wires, which can cause a fire hazard. Modern electric blankets have improved safety features, such as automatic shut-off and temperature settings, which can reduce the risk of overheating and fire. However, older models may not have these safety features, so it is important to check and replace worn-out blankets.

Fire and burn hazards are a concern
The number one concern when using an electric blanket is its potential to overheat. If left on for an extended period or if the fabric gathers in one area, an electric blanket can become a fire hazard. This risk is heightened if the blanket is old or has worn cables, so it's important to regularly check for wear and tear and stick to the manufacturer's guidelines.
Electric blankets are filled with wiring, and if the wires become frayed or crimped, they can cause a life-threatening scenario. A damaged cord is a sign that the electric blanket should no longer be used, as it poses a fire risk. It's also important to address any tripping hazards presented by the controls and wires.
In addition to fire hazards, electric blankets can also cause burns. This is especially a concern for those with certain medical conditions, such as diabetes, which can result in neuropathy and a lack of sensation in the feet. Individuals with circulation issues may also be less sensitive to heat levels, making them more susceptible to burns.
To minimise the risk of fire and burn hazards, it's important to purchase a good quality electric blanket from a reputable brand, follow the manufacturer's guidelines, and regularly inspect the blanket for any signs of wear and tear.

They may interfere with sleep cycles
Electric blankets emit electromagnetic fields (EMFs) and, while research is inconclusive, some have expressed concerns about potential links to cancer, fertility issues, and pregnancy risks. One doctor has stated that radiation from electric blankets can possibly damage a woman's eggs and a man's sperm.
However, one of the most significant concerns regarding electric blankets is their potential to interfere with sleep cycles. Our core body temperature drops a few degrees as we sleep, and lower body temperatures have been linked to a faster onset and better quality of sleep. By creating a continuously heated environment, electric blankets may interfere with the body's nocturnal temperature cycles, thus disrupting sleep.
Dr Eve Glazier and Dr Elizabeth Ko have suggested that using an electric blanket through the night could be damaging to your sleep patterns. They state that "creating a continuously heated environment may interfere with the body's nocturnal temperature cycles, thus interfering with sleep."
Many experts have found that sleeping in a cold room is better for you as your core temperature needs to drop to signal to the brain and body that it's time to sleep. This lower temperature helps people fall asleep faster and sleep more deeply.
To avoid this issue, some people choose to use an electric blanket to preheat their bed, turning it on an hour or so before bedtime and then turning it off before getting into bed.

They can be dangerous for pregnant people
Electric blankets can be dangerous for pregnant people. Firstly, electric blankets emit electromagnetic fields (EMFs), which have been linked to fertility issues and pregnancy risks. Although research is inconclusive, it is recommended to exercise caution when using these blankets during pregnancy.
Secondly, electric blankets can pose a fire hazard, particularly if they are old or have worn cables. This risk is heightened for pregnant individuals, as their changing physical condition may make it more challenging to escape from a fire quickly. It is crucial for pregnant people to ensure their electric blankets are in good working order and to follow safety guidelines to minimise the risk of fire.
Additionally, electric blankets can cause overheating, which may be dangerous for pregnant women. Pregnancy can already make women feel warmer due to hormonal changes and increased blood volume. Using an electric blanket may further elevate their body temperature, leading to discomfort and potential health complications.
Lastly, electric blankets may interfere with the body's natural temperature regulation during sleep, disrupting sleep cycles and affecting overall sleep quality. This disruption can be particularly undesirable during pregnancy, when getting sufficient rest is crucial for both the mother and the developing fetus.
While electric blankets can provide warmth and comfort, it is recommended that pregnant individuals exercise caution and consult with their healthcare providers before using them.

They may be unsafe for those with medical conditions
Electric blankets can be safe to use, but they may pose health risks for certain groups of people. One of the major concerns with electric blankets is the potential for the blanket to overheat, which can be dangerous for those with certain medical conditions.
For example, people with diabetes may have neuropathy, which arises from damage to the peripheral nerves. This can cause them to have no sensation in their feet, which could result in burns if they are unable to feel that the blanket is too hot. Similarly, those with circulation issues may be less sensitive to heat levels, which could also lead to burns.
Additionally, electric blankets emit electromagnetic fields (EMFs), which have been linked to potential concerns about cancer, fertility issues, and pregnancy risks. While research is inconclusive, it is recommended that pregnant people avoid using electric blankets due to the potential risks associated with radiation exposure.
To ensure safety, it is important to follow manufacturer guidelines, regularly check for wear and tear, and avoid using old or damaged electric blankets, as they can pose a fire hazard. It is also recommended to consult a healthcare professional if you have any medical conditions or concerns about using an electric blanket.
