What You'll Learn
Electric blankets and overheating
Electric blankets can be dangerous and one of the potential risks is inadvertently overheating the body. While there is no scientific evidence that using an electric blanket will impact a heart condition such as atrial fibrillation, becoming overheated can stress the heart, which might trigger an episode.
There have been rare cases of heat stroke deaths caused by elevated core body temperatures due to sleeping with an electric blanket. The core body temperature drops a few degrees while sleeping, and lower body temperatures have been linked to a faster onset and better quality of sleep. Electric blankets, by creating a continuously heated environment, may interfere with the body’s nocturnal temperature cycles, thus disrupting sleep.
Some people may be more vulnerable to overheating or burns from electric blankets. Older adults, for example, may have altered temperature receptors, meaning they cannot feel if the blanket is too hot. People with certain medical conditions, such as diabetes, may experience neuropathy, which can interfere with their sensitivity to heat. Those with circulation issues may also be less sensitive to heat levels, and doctors may advise against using electric blankets.
To prevent overheating, it is recommended to use an electric blanket to preheat the bed and then turn it off before getting in. Modern electric blankets have safety features such as automatic shut-off to prevent accidental overheating. It is important to ensure that the blanket is functioning correctly and to follow the manufacturer's directions for placement, maintenance, and cleaning to minimise any risks.

Electric blankets and electromagnetic fields (EMFs)
Electric blankets emit electromagnetic fields (EMFs) and are a source of extremely low-frequency electric and magnetic fields. There is ongoing research and debate about the health implications of EMFs. While EMFs are present in the natural world, they are also generated by power lines, electric wiring, wireless communication devices, and electrical appliances. The concern is that since our bodies generate billions of tiny electrical impulses, exposure to external EMFs may present a health hazard.
There is a lot of speculation about the connection between EMFs and cancer. However, it is important to note that the EMFs emitted by electric blankets are non-ionizing and do not damage cells or DNA. Most studies suggest that the EMFs emitted by household appliances, including electric blankets, are far below the levels that could cause health issues.
One of the concerns regarding electric blankets and heart health is their potential to interact with implanted cardiac devices such as pacemakers or defibrillators. While modern devices are designed to shield against most EMFs, individuals with these devices are generally advised to consult their doctors and manufacturers regarding the safety of using electric blankets. There is a potential for interference, especially if the blanket is very close to the device.
Additionally, for individuals with unstable angina, arrhythmia, or other sensitive heart conditions, the additional heat from an electric blanket might trigger symptoms. This is because becoming overheated can stress the heart and potentially trigger an episode. However, it is important to note that there is no scientific evidence that using an electric blanket will impact atrial fibrillation specifically.

Electric blankets and cardiac devices
Electric blankets emit electromagnetic fields (EMFs) and there has been ongoing research and debate about whether exposure to EMFs can affect heart health. While most studies suggest that the EMFs emitted by household appliances, including electric blankets, are far below the levels that could cause health issues, there is a potential for interference with implanted cardiac devices such as pacemakers and defibrillators.
Individuals with pacemakers or implanted cardiac devices are often advised to exercise caution with any electrical devices due to the potential for interference. This is particularly relevant if the electric blanket is very close to the device. Boston Scientific and Medtronic, two of the largest cardiac device manufacturers, list electric blankets and heating pads as "safe under normal use" or "no known risk". However, it is still recommended that individuals with these devices consult their doctors and the device manufacturers regarding the safety of using electric blankets, as modern devices are designed to shield against most EMFs.
There is also a concern that the additional heat from an electric blanket might trigger symptoms in individuals with unstable angina, arrhythmia, or other sensitive heart conditions. Becoming overheated can stress the heart, which might trigger an episode. Older adults may also be at risk of burns from electric blankets as their skin may have altered temperature receptors, meaning they cannot tell if the blanket is too hot.
To minimise any potential risks, it is important to ensure that your electric blanket is functioning correctly and adheres to safety standards. Modern electric blankets are equipped with safety features such as automatic shut-offs and adjustable heat settings. It is also recommended to use the electric blanket to preheat the bed and then turn it off before getting into bed.

Electric blanket safety features
Electric blankets have been associated with several potential health risks, including overheating, skin burns, and interference with cardiac devices. However, modern electric blankets come with various safety features that aim to mitigate these risks.
One key safety feature is the automatic shut-off function. This feature helps prevent the blanket from overheating and reduces the risk of fire or burns. It is important to ensure that this feature is functioning correctly and that the blanket adheres to safety standards.
Another safety feature is adjustable heat settings, which allow users to control the temperature of the blanket. This feature is particularly important for individuals with pre-existing cardiac conditions, as the additional heat from an electric blanket might trigger symptoms. It is recommended that users with heart conditions or implanted cardiac devices consult their doctors and the device manufacturers to ensure safe use.
To further minimize the risk of overheating, it is recommended to use the electric blanket to preheat the bed before turning it off or removing it before getting into bed. This helps create a cozy environment without the continuous heat that may interfere with the body's nocturnal temperature cycles and impact sleep quality.
Additionally, addressing tripping hazards presented by the controls and wires is crucial. Following the manufacturer's directions for placement, maintenance, and cleaning is essential for safe use.
While electric blankets may pose potential risks, modern safety features significantly enhance their safety profile. However, certain individuals, including those with circulation issues, altered temperature receptors, or specific medical conditions, should exercise caution or avoid using electric blankets altogether.
