Cold Air as Tonic
Has SpccialVaiuc Because ofInereos.
cd Oxygen

There IL wonderful value in fresh,
cold out of door air, particularly when
accompanied by sunlight. Light and
air are Natures most powerful tonics.
There is marvellous power in sunlight.
This is clearly seen in vegetation. y
scrawny plant. struggling for existence
in a dark corner of the house. and hay
ing only two or three little green
leaves on il. when taken out into the
light and air. becomes wonderfully
transformed in few days. II puts
forth buds and leaves, and the bios
SONS soon follow.
The same thing is true Of human
beings. They. as we'll as plants. are
vital organisms. like plants requiring
sunlight and air. Thousands of pco-
pie are losing health and growing thin
and sickly because they live indoors.
Contains More Oxygen.
Cold. fresh air has special value be-
cause ii stimulates the organs and all
the functions OF the body; II uulckens
the heart to the greatest activity, and
increases the numbcw of red corpuscles
in the blood. cold air also contains
/ more oxygen To the cubic inch than
does warm air. The volume OF the
air is reduced one FIVE hundredth mart
for each d"Src" OF reduction in tenn
nerature. Consider the difference be-
tween n very hot summer day, with n
: temperature Of roo degrees and "a win
ter day at Zcro--a Temperature differ

loGG. NJ. -, in Good Health The air
has been reduced one-ffth of It's vol
umc, and in four hrcaths Of cold one
gets ms much oxygen as he would In
hEe prcathS OF warm summer air
Fence the body may take in one-fifth
more oxygen In cold weather than in
'of oxygen taken into the body Is n
matter OF great consequence II eX-
plains why one feels better in cold air
n brisk walk on IL cold. crisp winte err
morning creates splendid annette
for breakfast, for tho same reason that
the fire burns brighter on Il cold win
ter night. When the fire burns with
particularly bright glow. people are
wont 10 say, winter is coming: see
how bright the fire burns" This is
due to the increased amount of oxy-
gen In the air. The fire burns bright .
er and faster because IL has onc-fifth
more fuel supplied.
Aids Digestion
SO with the body. vital fires burn
brighter in cold weather The whole
tide of life moves with greater activ-
ity. The process of digestion is ouick =
cncd because the process OF oxidation
is increased Also the oxygen we
breathe In cold air improves the func-
ton OF the liver. so that it does more
work. The muscles. also, depend for
their activity upon Oxygen. In an eX-
cess OF carbonic acid gas the muscles
are asphyNiatcd, and so one feels de
pressed in warm weather and in over
heated, hnventilated rooms. One does
not get ont OF breath so easily in cold
: air as in warm. Tho woodchoopcr can
swing his AK with more energy on
/ "a cold day. Cold air aids in the elimi-
/ nation Of the poisonous matters which
! ar" al! tho time forming within tho
, body When oxygen Is not plentiful
enough TO make the vital fires burr
sufficiently TO consume the fuel an(
vast" ar the body. then much vast,
material is left behind In the form o.
liinperfect!y burned substances. which
may be called the cinders Of the body
