science Question!

While day dreaming in history class, A question popped into my mind; If our body temperature is 98 degrees Fahrenheit (37 degrees Celsius) why are we uncomfortable in hot weather?

Our bodies generate heat during metabolic processes... This means that we regulate our temperature to 37C by sweating to cool down or using vasoconstriction and hairs going up etc. the reason our bodies regulate to that temperature is because that's the temperature that our bodies reactions work best at - enzymes are catalysts for our bodies chemical reactions, they're sensitive to temperature, a bit either way and they're much less effective. Too hot and they get denatured, stop working permanently.

What ambient temperature is just right for each person is variable. The reason we feel uncomfortable in hot/cold conditions would be feedback, telling us to move or get warm/cool. It's the same idea as burning your hand, if the thing is painfully hot you let go of it.

Oh and the reason we shiver is connected to us making heat, your body shivers to make your muscles work and make heat. After a run you can be too warm, even on a nippy day I can wear a T-shirt and jeans on my bike and ride fast all the way to somewhere, then be warm afterwards or break a sweat.

Your muscles don't burn with the heat they produce though... That's lactic acid buildup. Guitar hero or similar games provide a good way to show it, play something really fast until your arms feel like seizing, they'll be warmer than the rest of your arm, not massively but it's noticeable.

thanks killerjackalope! how'd you get so smart! :-)
One word - wikipedia.
Nope, not a word of it - basic GCSE biology there...
Nope - AA in science despite not handing in much coursework...
I think I must have done a 9V, or maybe a lantern battery, in science ;->
I could have DD
its ok, i only joke. BB myself, and i didn't try one bit for that..
It was an easy enough subject, I never bothered much with it.
