the heat, more often are caused by
some exertion on top of a physical
disability, according to experts of the
Public Health Service.
Several different types OF people
with disabilities fall subject to the
fatal severe temperatures now pre-
valiant throughout the Middle West
and East, 1t was explained Doctors
of the Public Health Service generally
believe, however, that most of the
deaths come from the heat disturbing
body functions, and going fatally to
a weak heart.
When the victim begins to suffer
from high temperatures the pulse rate
jumps from an average of 10 or 72 a
minute up to as high as more than
180 a minute. This tires the heart,
as its only rest comes between beats,
and sometimes results in death.
Bodily Temperature Rises.
When victims are stricken by the
heat the heat-control mechanism of
the body gets out Of commission and
body temperature rises indefinitely
from the normal 984 degrees, until
sometimes it reaches ITO or 112.
Occasionally there are breakdowns
in the human system from heat, the
exact cause Of which medical science
has not yet determined, it was ex-
| planned. But is Is believed that where
the heat-control mechanism of the
body gets entirely out of commission
| the body heat may get so high it some
times affects the brain cells, causing
death.
| Widely different symptoms come to
persons suffering from sunstroke on
the one hand, and heat exhaustion
| on the other, doctors Of the Public
Health Service explained. In the case
Of sunstroke out of doors, where the
victim suffers severely, the human
body feels very hot to the touch, as
| If burning hot But in the case of
heat exhaustion, like that of men
overcome while working as stokers in
vessel, for instance, the body is
cold and clammy.

temperatures in scientific expert
mentS, without death.
AS far back as ITS records show
that group of men withstood for a
short time in a superheated room a
| temperature Of 211 degrees with
| feeling that it was "unpleasantly hot,
with a sense of scorching on the face
and arms which were bare" The
humidity in that case, however, was
very low.
Terrific heat and high humidity
cause men in deep mines to suffer to
the extent that conditioning ap-
paratus has had to be installed. In
some deep metal mines in the West,
for instance, records show that the
temperature of the rock stands regu-
larly at between 1O8 and ITO degrees,
with humidity 100 per cent. The
| deepest mines in the world are the
| gold mines of South Africa. now run

| the surface, where the heat would be
unendurable except for air-condi-

Death from heat and i'll effects
superinduced by the heat. usually take
place, scientists say, when the body
temperature is raised to between 109

symptoms Described.
The direct symptoms in persons suf-
fermg from heat are given as cramp.
headache pain in the back, dizziness,
great thirst. chillineSs, although the
body temperature might be high, diar-
rhea, restleSsness and insomnia. Heat
sufferers usually show changes in
body temperature, pulse rate. and
blood pressure, increased respira ton
and body metabolism and loss of
weight.
Practical suggestions for the gen.
eral public in hot weather are offered
by the Public Health Service, to safe
guard health, and increase personal
comfort and efficiency.
h Painting sometimes can be pre-
vented. If you begin to feel dizzy,

tors say quietly lower the head by
leaning over, or lying down with the
body higher than the head so the blood
can run to the brain. Application of
cold wet cloths to the face and head
will help.
One good rule to follow. on food, is
to stop eating when the stomach is
satisfied.
The food should be light, nutritious,
and easily digestible. Fresh fruits and
vegetables are especially desirable.
Fried foods. pastries. and other sweets
should be curtailed as they contribute
materially to heat production. Ice
cream and nourishing ices are accept
able hot weather foods and should
occupy prominent place in the diet.
Milk Fine Drink.
Concerning thirst, warning is is
sued against overindulgence discom-
fort. and even grave injury. Milk is
described as one of the finest hot
weather drinks, both thirst quenching
and of high food value. Fruit juices
are also excellent for the same reason.
A fairly liberal amount of cool water
