Heating Pad Safety

Heating pads are often used to relieve joint or muscle pain or provide soothing heat for other ills, and they are generally considered safe and effective. They aren't always safe, though. Always follow the manufacturer's instructions when using a heating pad. In addition, pay close attention to how long you use a heating pad and to the condition of that heating pad so that you can use it safely.

Length of Use

Using a heating pad for long periods of time increases the risk of damage to the skin, such as burns. You can purchase a heating pad with an automatic shut off, but even with such a safety device, you should check your skin every 20 minutes or so to make sure the skin is not excessively red or showing other signs of damage or injury. Don't use a heating pad overnight or when you are sleeping because you may not wake up until burns or other injuries are serious.

Condition of the Heating Pad

Even new heating pads should be inspected for damage or imperfections, but older pads are more likely to show signs of wear or other damage. Electric cords can become frayed and the insulation around the wires inside the pad can become worn thin, increasing the risk of fire. Inspect heating pads every single time you use them for signs of damage and don't use a heating pad if something doesn't look right. Heating pads are not very expensive and it's safer to replace them than try to repair them.

People That Should Not Use Heating Pads

Infants and young children, people with physical disabilities that make it difficult for them to sense heat on the skin or difficult to move independently, and people with certain other medical conditions should not use heating pads due to the risk of burns or other injuries to the skin. Ask your physician if you're not sure if heating pads are safe for you or for a loved one. Pregnant women should use heating pads with caution and seek the advice of their midwives or obstetricians.
