Our body temperature is 98.6 degrees, so why can we comfortable live...?

Question

in 50 degree weather (about 50 degrees less than our body temp) but can not live in 150 degree weather (about 50 degrees more than our body temp.)

Answer 1

I'm no doctor, but here's my engineering analysis of it. The body's heat-generating mechanisms are much more efficient than its cooling-off mechanisms. In fact, the body automatically generates internal heat (through metabolic processes) regardless of the external environment, which is why 98.6-degree weather does not feel comfortable. It's very much like the situation with your computer. It operates efficiently at a particular temperature, but because it is constantly generating more heat, it cannot maintain that temperature on its own, which is why cooling fans are necessary.

Also keep in mind that the generation of heat is internal, while convection and the evaporative cooling of sweat are obviously external, although blood does help carry heat from the warmer internals to the cooler skin. Since it is primarily the internal organs (including brain) that are most sensitive to fluctuations in temperature, you can see why a cooler environment is much more tolerable than a warmer one.

~70-degree air is considered the ideal environment ("comfort zone") for humans, which probably means that it can remove heat by convection (without help from sweat evaporation) from the surface of a normally-clothed, average-sized human body at about the same rate as the body's normal internal processes are producing it. In engineering we call this a steady-state process.

Answer 2

I don't know but when it is 98 degrees outside....i can't stand it...LOL

Answer 3

our bodies can react to keep us warm enough but cannot cool us down fast enough to survive

Answer 4

beats me

Answer 5

look up psychometric
