However, while electric blankets can offer these benefits, it is essential to use them safely. Improper use of electric blankets can lead to several potential risks. One concern is overheating. If the blanket is set to a high temperature for extended periods, it can cause overheating, leading to dehydration or other heat-related issues. It is advisable to use the low or medium settings while sleeping and to turn off the blanket once the desired temperature is reached.
