Overheating the body with an electric blanket is a risk of electric blanket use, particularly for those with diabetes and other medical conditions. A person with diabetes may have an insensitivity to heat that makes it difficult to tell that the blanket is too warm. This lack of sensation can result in burns in extreme cases.
There is no information available on what percentage of people use an electric blanket. Many people choose not to use them because some blankets may be fire hazards. Also, diabetics are warned not to use them.
