If Our Body Temperature is 37° C, Why Do We Feel Hot When it’s 37° C Outside?

Everyone says that the ‘optimum’ body temperature is 37 degrees Celsius (98.6 degrees Fahrenheit). But if the temperature of your surroundings is 37 degrees Celsius, most people will start to feel warm or even hot. Why does that happen? If the ambient temperature crosses 37 degrees Celsius, we start to feel hot because our bodies are not able to shed the heat they produce, as a result of metabolic activities (within the body), which makes us feel hot. Our body works best when the ambient temperature is around 70 degrees Fahrenheit (21 degrees Celsius) because, at this temperature, there is a stable difference in the temperatures of the body and the surroundings. Consequently, heat transfer occurs as heat travels from a region of high energy (our body) to a region of low energy (our surroundings).
