Question

a doctor advises to use ice pad on forehead to bring high fever down instead of using water at zero degree celsius. why?

Answer 1

There are several reasons for this.

An important reason being that one cannot ‘place’ water on the forehead. Instead it is convenient to use solidified water as ice cubes or blocks, wrapped in a piece of cloth. Clean and pure water solidifies at 32 degrees Fahrenheit or zero degree Celsius.

This is done to bring down the temperature of the human body, quickly.
