Why is our body 98.6F?...When the temperature outside is 90F and we are sweting?

Question

I really need some help with this quiestion. Please if somebody can help me.
thank you.

Can some one help me to find a website which provides some information refering this question.
Thank you!

Answer 1

The body has a temperature controlling centre in the brain called hypothalamus.The body temperature has to be maintained at 98 degree F. This is important to see the internal reactions going on at the desired level. When the external temperature drops, the body has to counter this by increasing the internal temperature to maintain its internal temperature. In this case the body shivers so that muscular movements generate heat. This happens when the mitochondria of the muscle cells produce ATP. Conversely, when there is excessive heat outside, the body perspires to prevent the body from excessive heat of the external environment.

Answer 2

Fahrenheit, the German scientist who invented the scale of that name, wanted to make 0 as cold as he could get, and since there isn't an upper limit on heat, he decided to make 100 the human body temperature. He botched both ends of the deal; one can produce temps colder than 0 F with little more than Fahrenheit had, and he got the average body temperature wrong as well.

The human body produces a considerable quantity of heat -- about 100 watts, when doing nothing except breathing, and much more when active. That heat has to be dissipated, and if it is too hot, that becomes a problem: sweat can evaporate to remove heat, and you will still lose heat through respiration. If the humidity is high, sweat does not evaporate well, and you are really bothered by the heat.

Answer 3

This body is a very sophisticated machine, there are internal temprature controls which work to keep the body at 98.6F (+/- 1 Degree) this helps the fluids in the body to stay regulated.

When it is 100 Degrees outside the body cools its biggest organ (Skin) internally we still have the same temp.

Answer 4

That's because our body trying to maintain it's core temperature constant in 98.6F.

Our body metabolism generates a lot of heats when we're active and 90F outside temperature is hot enough to increase core body temperature. Therefore our body respond those increasing temperature by releasing sweat to keep our body temperature in normal range.

Answer 5

Even though your average body temperature is higher than the external temp, you are still generating more heat than you need to maintain your internal conditions. So we sweat to lower our outer body temp to regulate the core temp. Make sense?

Answer 6

Homeostasis - the body's internal system that always strives to achieve balance.
Type it into a search engine and be marvelled at how fantastic your body is keeping you alive whilst you eat, sleep, crap etc.

Answer 7

It is a combination of many things, but a major factor is because our hair and clothing insulate us and retain heat.
