MEN OF GIRTH CAN
 STAND HEAT EASILY
Thin Men More Likely to Become
 Exhausted From It

Pittsburgh. April 20 tBy Associat- ed Press) Fat men endure high temperatures and excessive humidity better than thin men, and ice water does not necessarily develop intestinal distress. These facts are disclosed in report of experiments conducted here by the American Society of Heating and Ventilating Engineers in cooperation with the United States bureau of mines and the Carnegie Institute of Technology.
 In experiments to determine the relative effect of various tempera- lures and humidities on the human body, the scientists also found that sweat is the chief factor affecting the eyes when the human body becomes heated.
 The object of the experiments was to establish the exact degree of tenn perature and of humidity or "com- fort lines" human being should be subjected to in room. The prob- lem was first attacked several years ago, and the research work has now reached point where definite results have been obtained. First experi- ments were to study the physiological effects of temperatures and humid ities on human subjects in still air, and for these staff of physicians and employees of the society have subjected themselves to great hard ships.
 Variations of Temperature.
 s,,,,, If oy,< lfc of the experiments was the discovery of the great variations of external temperature which human being can endure. and at the same time re- tain his physiological efficiency. An other fact developed was that in- creasing pulse rate is more the cause of discomfort than is body tempera- ture when in heated room.
 While irrelevant to the present study, an attempt was made to de- termine the cause of inflammation of the eyes, and also to determine whether drinking of ice water pro- duces cramps, as so often complained of by industrial workers" said the report.
 "On a day when the eyes were nor nal, a small quantity of sweat, which had been collected during an experi- ment, was dropped into the eye. The almost immediately be- came inflamed and the eye felt sore The sweat collected from the face seemed les sirrita ble than sweat from the chest or arms. Sweat-bands were then applied to the forehead. prevent ing the sweat from entering the eyes. There was no inflammation This proves sufficiently that sweat is the chief factor in producing conjunc- tivitis which accompanies exposure to heat.
 Tt has frequently been stated that workers exposed to high tempera- lures developed severe cramps after drinking ice water. A few of the l subjects of these experiments volvn- teered to drink ice water after about an hours exposure to high temper ature, and two of them, in one ex- pertinent, drank quart of ice water In less than 15 minutes without i'll effects. Cramps did not develop in any of the subjects at any time"
 Heavy Men Lose Weight.
 On entering and leaving the spe- cially heated chamber. the report shows, loss of weight varied with the the heavier and stouter man losing more than the light and | thin one. Notwithstanding this, the lighter man, as rule. could not en- dure the temperature conditions as lopC and com mpIa ined mora Of tho | exhaustion which followed.
