Why a person feels hot when the weather is 37.5 'C Giving that the person's normal temp. is 37.5 C?

Answer 1

Human bodies generate about 60 W of heat, even when we're just hanging out. We need to be able to dump this heat outside ourselves or we'd slowly overheat. 37.5 is the core temperature, the skin temperature is much lower. Once the ambient temperature begin to close in on our skin temperature it starts being harder for us to lose heat to the outside, and once ambient temperature reaches or surpasses the core temperature it becomes very hard indeed for us to lose any heat to the outside. ANd when we can't shed heat at the required rate anymore we feel warm.

Answer 2

When the weather is 37.5°C, there is no temperature difference between a person's body temperature and the environment, so the body struggles to dissipate heat. This can make a person feel hotter due to reduced efficiency in the body's cooling mechanisms like sweating and heat transfer to the environment.
