Body Science. If the human body temperature is typically 98.6 degrees, then Why is it very uncomfortable when the outside temperature?

turns over 98 degrees... Scientifically speaking. What happens to the human body, if the outside temperature goes over 98.6 degrees?

    The body generates heat internally. Most people also wear clothes, and clothes keep the heat from escaping. When the outside temperature is the same as the human body, then the heat that the body generates cannot be lost to the environment unless we sweat or get into water that is colder than the body. When the body overheats, it damages our internal organs. It is known as hyperthermia. Hyperthermia can kill by causing organ failure. The brain will also die if our body temperature is too high.

    The body can cope by sweating even if ambient temperature is over 100 degrees For example, the temperature inside a car on a hot day can quickly rise above 100 degrees, and yet we can still cope if we keep drinking lots of fluid. Sweating cools us down because whan water evaporates from our skin, it takes heat, and the heat comes from our body. However, water cannot evaporate when the air is humid because it is already saturated with water. That is why hot and humid weather are more deadly than dry heat in the deserts.

    Because of a fundamental fact from physics: heat ALWAYS moves from high to low, i.e. from a region of high temperature to a region of lower temperature.  So in a hot environment, it's not only harder for the body to dissipate its heat, but if ambient temperature is higher than body temp, then in fact, heat flows IN.  Only way the body has of dealing with that is to shunt more blood flow to the skin, and to increase sweating.  Those are not very efficient at a higher ambient temperature, so you feel very uncomfortable--especially if at the same time the humidity is high.  That's why hot days don't seem so bad when it's less humid ("at least it's a dry heat").

    This "high-to-low" principle is also why a glass of water cools down when you put ice cubes in it--cold is NOT flowing from the ice cube to the water, rather, heat is flowing from the water to the ice--the lost heat energy goes toward changing the state of the ice cube, i.e. melting it.

    That's too hot for many

    the body has to work in reverse, instead of trying to heat up to its normal temperature it now has to work to cooldown to that temperature which is something the body isnt used to doing if you live in a colder climate. The human body is actually amazing at regulating its internal temperature to the perfect degree. The uncomfortable reaction you are feeling when it gets hot is your body telling you to seek a cooler enviroment
