36 degrees Celsius converts to 96.8 degrees Fahrenheit. The normal body temperature of a human is 98.6 degrees which would be 37 degrees Celsius.
Things like clothing can retain heat in the summertime when it is very hot outside which makes us feel hot and causes us to sweat. Strenuous activity also makes us feel this way.
The temperature in the body is controlled by a mechanism called thermoregulation. It acts like an automatic control system and responds to negative feedback.
Temperature sensors throughout the body respond to the central controller in the medial preoptic/anterior hypothalamic region of the brainstem, which then adjusts heat production and loss accordingly.
Thermoregulation assists us in maintaining the correct temperature regardless of external conditions. Some external conditions would consist of temperature, vapor pressure, air velocity, and insulation.
