Since the normal body temperature is 98.6 degrees, then why does the weather feel hot at the same temp?

The body makes an excess of waste heat that has to be disposed of, so we are more comfortable at a temperature below 98.6. Above 85-90 degrees F, we actually have to sweat to get rid of this excess heat, and this actually takes additional energy to do (as well as water loss).

98.6 F is the temperature inside the body, not outside.

its same like an engine hot inside but from outside it doesnt want heat and needs cooling

When your body converts food to energy, there is extra heat generated. When your heart beats, heat is generated. When you work your muscles there is excess heat.

This excess heat has to go somewhere, so it goes into the air. When the air is close to or higher than the body temperature there is no place for the heat to go, so you feel hot and can even have a heat stroke if you exert yourself too much in hot temperatures.

Because humidty and other factors of the weather including wind can cause the evaporation of sweat that can cool your body significantly. The way your body "feels" in an environment is dependent on more than just temperature.

Good question. Never considered that. I don't have AC but am perfectly comfortable sitting in front of my fans - until I turn in the newscasts and they tell me 98's real feel is 105. On and on they go about the heat and how dangerous it is. Then I start to feel hot. Just mind over matter, I guess.

98.6 is your bodies internal regulator of heat due to homeostasis. Your skin plays a very important role because it has huge surface area in order to release heat from vasodialation and vasoconstriction.

I have wondered the same thing. I hope someone can answer it.....I just figured it had something to do with the way the outside temp feels to the nerve endings in the skin or something.

I think it has something to do with Homeostasis.

cuz of our skin..and suns rays
