ELI5 - If the body's internal temperature is roughly 37 degrees Celsius, why does it feel really hot when the outside temperature is 37 degrees Celsius?

Sorry not in Fahrenheit for our American friends. What is 37 Celsius in Fahrenheit?

Our skin is a natural heatsink. The heat from our core warms up the skin which is cooled down by the surrounding air. Sweating speeds up this heat transfer process. But if the air tempature and body temperature are both 37°C, this process slows down and we are venting less heat whilst constantly producing more heat, making us feel hotter.

Does it help if you imagine trying to cool boiling water down with boiling water?
