All systems Of heating aus some
air movement. Open windows, open
doors and crate fires also promote
air movement. Air movement is ex-
tremely important.
The most effective system of ven
tilation consists OF opening windogs.
Cross ventilation by means OF two
windows. or a window and a door
in opposite sides of the room, Is par
ticularly effective. Opening enough
to cause a current Is all that Is re-
quired.
The extent to which windows are
to be opened in our sleeping apart
ments must depend on outside at
mospheric conditions.
Everyone should sleep in q room
with open windows. In this way an
ample supply of fresh air can be Sc
cured for eight hours out OF the "a
at least.
A simple method of securing srosh
air from a window Is to raise the
window two or three inches and
place q neatly fitting board under 1t.
This will prevent a direct draft
and permit OF a free current OF air
coming in between the upper and
lower sashes.
Another excellent method OF VEN
tiiation Is TO place in an open win
dow an ordinary window screen COW
cred with cheesecloth. Two or three
layers may be used. This arrange
ment breaks the wind and keeps out
the snow. The heat loss is very lit
. greater than the loss by radiation
from the surface Of pane glass.
L II one depends on simply open
Ing the window. from a haif-inch to
an inch may be sufficient on very
cold nights. If you hold your hand
opposite a half-inch opening. you
Will ind the current of air coming
in is much greater than that which
one or two persons could possibly in
hale and exhale constantly.
There is nothing gained by throw
ing the window open to a degree
beyond that already suggested, pro-
viding there is sufficient difference IN
the temperature outside and In.
Anemfa
What Is anemia? Is It durable?
Anemia, after all, Is only a symp
tom. In the treatment. II is i'm
portant to determine the cause OF
the condition. There are many diff
ferent causes and only a physician
can arrive at a satisfactory dag
nosis.
The Public Health Service has no
bulletins dealing with anemia. Mere
ly to indicate to you how important
1t Is to ind the cause of the ane-
mia. If possible. let me tell you some
Of the common causes of this con
dition: Malaria, lead poisoning,
hook worm, bright's disease. repeat
ed hemorrhages. auto-intoxication
tuberculosis and cancer.
Do not let this list cause you any
unnecessary alarm. I have men,
toned this to show how impossible
1t is to give you satisfactory advice
In the shape OF a reply through the
column.
Influenza
Is there a vaccine to prevent In
fiuenza? I had the disease in 1918
and I'm afraid OF a recurrence.
Many have asked this question
Up to the present time no vaccine
has been discovered for which We
can claim anything definite SO far as
the prevention Of epidemic influenza
Is concerned.
Until we discover the germ that
is responsible for the disease, we
cannot prepare a vaccine to ward of
attacks. But you may be glad II
know there Is reason TO believe thai
a previous attack of influenza appar-
entity confers a certain degree of i'm,
munity to another attack. Just how
long this immunity lasts is moi
known.
