While a modern, well-maintained electric blanket is unlikely to cause problems with proper use, overnight use is not recommended.
Instead, it’s helpful to use electric blankets to warm up your bed before you get in, and to turn them off before you fall asleep.
Can I leave my electric blanket on all night?
Electric blankets generally shouldn’t be left on overnight unless your blanket includes a special thermostatic control for safe use overnight. Always check the blanket’s guidelines ideally before purchasing it to check if it allows for use during the night.
How safe are heated blankets?
Another concern with heating blankets is that they may get too hot or if kept on one area of the body for too long, they may cause burns. In the U.S., it’s advised to only use electric heating blankets that have the Underwriters Laboratories (UL) mark, indicating that the product has been safety tested.
Are heated blankets worth it?
The blanket is made of coiled wires that heat up when plugged in to an electrical power source. But like most electrical items, this can cause several fire risks, and unlike other bedding, electric blankets have unforeseen disadvantages. The extra warmth may not be worth it in the long run.
