If our body temperature is 98 degrees, why does it feel hot to us when it's 98 degrees outside?

Answer 1

Our body radiates out heat to the cooler air. As the air becomes close to body temperature the rate of heat conduction drops.

The basic physics is that heat conduction between 2 bodies increases when the temperature between the 2 bodies increases. Conversely, heat conduction reduces when the temperature difference between the 2 bodies decrease.

Secondly, as the temperature rises, the air can contain a lot more moisture. Our bodies cool to some degree by water evaporation. As the dew point rises (moisture in air rises), the rate of water evaporation also drops so cooling from evaporation drops.

If you immerse yourself in a tub of water at 97 deg F, you will become cold over time. This is because water is a better temperature conductor than is air - and the water is colder than your body.

Answer 3

No, because that core body temperature is maintained at a cooler outside temperature, the 70 degrees that you state. The fat and other things in our bodies keeps the inside warmer. If you were to put a person into a 98.6 degree heat, the body would get even hotter because of it's insulation and it couldn't function like that. ^^This isn't a very scientific answer- but just plain common sense.

Answer 4

Our bodies maintain a 98-degree temperature by expelling excess heat. This is relatively easy when the surrounding air is cool, but when the air temperature is equal to our body temperature, our bodies must work harder.

Answer 5

cuz its inside our body so we cant feel it.
