How does a wet towel bring a fever down?

A wet towel can help bring a fever down by promoting evaporative cooling. When a damp cloth is applied to the skin, the moisture evaporates, which cools the skin and, in turn, helps lower the overall body temperature. This method is particularly effective as it allows heat to dissipate from the body, providing temporary relief from fever symptoms. However, it's important to note that this is a supportive measure and not a substitute for medical treatment if needed.
