The ice age was a long time ago, so warming has been going on for quite a while.

The sweat thus evaporated increases the amount of water > vapor in the air, thereby increasing relative humidity. Evaporation of sweat is excatly what keeps your body cool. As it evaporates, it absorbs heat from your skin. And this is why/how sweating allows your body to keep a temperature that is below ambiant temperature. And unless you are in an enclosed, air tight car, the amount of water you release into the air will just flow out of the room due to the fan pushing it out.

The more sweat that evaporates from your body, the higher the humidity gets, and the harder it is to keep cool through evaporation of sweat (because it evaporates more and more slowly as room humidity increases). This creates a vicious circle of ever-increasing sweat and discomfort, until the room humidity reaches 100%, at which point no amount of sweating will provide any cooling at all, no matter how powerful the fan. Heat exhaustion or heatstroke will often be a risk before this point is reached, however. > And unless you are in an enclosed, air tight car, the amount of water > you release into the air will just flow out of the room due to the fan > pushing it out. Typically fans are positioned such that they just move air around in a closed room. There may be little or no connection to the outside world, and certainly not enough to effectively exhaust humid air. -- Transpose mxsmanic and gmail to reach me by e-mail.

I would say most would open a window or leave the room long before that happened. >> And unless you are in an enclosed, air tight car, the amount of water >> you release into the air will just flow out of the room due to the fan >> pushing it out. > >Typically fans are positioned such that they just move air around in a >closed room.

Perhaps this was your failing. -- --- DFM - http://www.deepfriedmars.com --- -- |
