!' Why You're COLD When It's WARM I J; -4 nrT often happens in Winter tbat a person llv- ; T . ' ing in a steam heated apartment feels cold jl oven when the thermometer shows the 31. " necessary degree of warmth in the room. Of TO , course, there is a reason for this, and also a very simple remedy. The reason is that the III ; air in the room s too dryit does not -contain -at " enough moisture; and the remedy is, of course, Ml! to keep some water in the room all the time so jl ! that it can evaporate into the ojr. I 1 Our bodies, you see, are at all times exuding HI j moisture In the form of perspiration. Now this H j perspiration, even in Winter, amounts to a 'SI "' great deal more than one would think, being If' measured in the pints. To evaporate water. Mlf. heat has to 1)6 used up, and, as the body is .9 , warmer than the air, the heat to evaporate this perspiration Is taken from the body. Of course, then the body feels cold. V Here is still another illustration of this fact. I It has been shown by actual experiment that a man can stay in an oven heated to the boiling temperature of water and not get uncomfort- s ably hot that is, painfully hot. The heat makes him p'erspire, and the 'heat taken up by ovap- i oration from the .body keeps the body from i getting not. But suppose that the oven already ) contained in its atmosphere all the water vapor that it could hold. Then, as none could evap- 5 orate from the body, the drops on the body I would soon get near the boiling point. So, in s the room referred to above if it contains a good bit of moisture the evaporation from the body will not be so fast, and consequently tho body will not feel cold. ? In India the manufacture of ice is carried on ? to some extent toy a development of the above J process. The climate is very dry, so water will evaporate quickly. Shallow pans containing water are placed on wet straw, which, when S the wind blows through it, gets cold enough to s freeze. .
