STOUT ENDURE HEAT
BETTER THAN THIN
TESTS SHOW DRINKING ICE
WATER WHEN EXCESSIVE
LY WARM NOT MENACE.

Fat men endure high temperatures
and excessive humidity better than
thin men, and ice water does not nee
essarily 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, says the New York Irib-
une.
In experiments to determine the rel
alive effect of various temperatures
and ,humidities on the human body
the scientists also found that sweat is
the chief factor affecting the eyes
when the human body becomes heat
ed.
The object of the experiments was
to establish the exact degree of tenn
perature and OF humidity or comfort
lines" a human being should be sub
iected to in a room. The problem was
first attacked several years ago, and
the research work has now reached a
point where definite results have been
obtained First experiments were to
study the psychological effects OF tenn
peratures and humidities on human
subjects in still air, and for these
staff of physicians and employees OF
the society have subjected themselves
to great hardships.
One OF the most important results
of the experiments was the discovery
OF the great variations OF external tenn
perature which human being can en-
dure, and at the same time retain his
physiological efficiency. Another fact
developed was that increasing pulse
rate is more the cause OF discomfort
than is body temperature when IN a
heated room.
"While irrelevant to the present
study, an attempt was made to deter
mine the cause of inflammation of the
ewes, and also to determine whether
drinking of ice water produces cramps
as so often complained of by indus
trial workers" said the report.
"On a day when the eyes were nor
NAL a small quantity OF sweat, which
had been collected during an expert
ment, was dropped into the eye. The
coniunctive almost Immediately be-
came infamed and the eye felt sore.
The sweat collected from the face
seemed less irritable 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 conjunctivi-
it's which accompanies exposure to
heat
1T has frequently been stated that
workers exposed to high temperatures
developed severe cramps after drink
ing ice water. A few of the subjects
of these experiments volunteered to
drink ice water after an hours expos
ure to high temperature, and two OF
them, in one experiment, drank a
quart of ice water in less than fifteen
minutes without i'll effects. Cramps
did not develop in any OF the subjects
at any time"
On entering and leaving the special
ly heated chamber, the report shows,
loss of weight varied with the indi-
vidual, the heavier and stouter man
losing more than the light and thin
one. Notwithstanding this, the lighter
man, as a rule, could not endure the
temperature conditions as long, and
complained more of the exhaustion
which followed.
