Can you overheat your brain by using a heating pad to relieve a headache?

Using a heating pad on your head to relieve a headache is generally safe, but overheating can lead to discomfort or skin burns rather than directly overheating your brain. The brain is protected by the skull and has mechanisms to regulate its temperature. However, prolonged exposure to excessive heat on the scalp can cause local tissue damage or exacerbate certain conditions. It’s best to use heating pads with caution and for limited durations.
