when we go from the inside cooled

then something is wrong.
The skin Is the largest organ OF
the body. II II were spread out on
the ioor. II would be the size OF a
rug seven or eight feet square.
When the outer air Is cooler than
the body. the skin tries TO prevent
heat loss by reducing the amount
OF warm blood flowing through this
body covering layer. While Il is
impossible for the body TO prevent
loss OF heat by this mechanism, still
excessive dissipation OF heat is
avoided. But the skin loses heat
and acts as radiator In spite OF
all that the body can do. During
cold weather we lose two-thlrds OF
the heat value OF food through our
skins Slxty-hve cents OF every dol
lar we spend for food Is used to
the other hand. In the summer the
skin acts Ike refrigerator. We
secrete water into the outside skin
and the evaporation OF this water
cOols us.

The only health problem in arti-
tcIally cooled theaters. restaurants.
Office buildings and homes is the
difference In temperature and com
fort between the outside and the
inside air. There are several sep

end point This is a combination OF
three factors; namely, temperature.
humidity and air movement. When
the air Is saturated with moisture,
II feels hotter than air of the same
temperature with lower humidity.
Some recent work tends to show
that there should not be more than
10 degrees difference In tempera-
ture OF the air inside artifcially
cooled rooms as compared to the
outside air. But there should be 40
per cent less moisture In the air in
the refrigerated rooms. There
should be some air movement, but
not draft or wind. sufficient to
keep still air pockets forming
around people sitting In these
rooms. The greatest factor, how
ever. according to these investiga-
tors. is In the humidity OF the air.
Some restaurants and theaters
maintain 20 to 80 degree Fahren-
heit difference In temperature be
tween inside and outside air. Upon
entering such a room-maintained

feels a sense Of coolness and we'll
being. Then adjustment of the
body TO the temperature takes
place. and this sense OF well-being
disappears.
The internal temperature rises in
spite of all the skins valiant at
tempts to change itself instantane-
ously from a radiator to a refrigera-
tor. That is why dizziness, nausea
and even collapse may accompany
this rapid change from November
to July day.
We do not know enough about air
conditioning of rooms In the sum-
mer time to make rules as yet We
have had many years of experience
with heating rooms during the win
ter time We need research and
study upon the question of summer
air-conditioning Of Offices, homes,
theaters, restaurants and such
places. The necessary equipment
is expensive and special rooms must
be constructed. The differences In
temperature, humidity and wind
movements must be examined.
