had by its means, without taking a holiday. But where this can be
done, it is well to take it.

The headache, however, may be caused indirectly by the failure of some
of the organs to do their duty, when other methods must be adopted. The
use of tobacco so injuriously affects the whole system that headache
often results, and refuses to be cured unless the tobacco be given up.
It is hard to do this, but the difficulty must be faced. Cold, damp
feet are a common cause of headaches. Let these be well bathed (_see_
Bathing Feet) for some days, even twice or three times a day, and many
kinds of headaches will be cured. Constipation, or sluggish action of
the bowels, frequently causes headache. The cure is obvious (_see_
Constipation). Imperfect action of the kidneys also causes it. In such
a case apply a large, warm bran poultice (_see_) across the back behind
the kidneys. Oil the skin before and after poulticing. Do this once a
day at bedtime for a week, if necessary, but not longer than a week at
a time. Take half a teacupful of water before each meal. Use freely the
lemon drink described in Drinks, Refreshing.

Headache, Sick.--The stomach and head affect each other powerfully, and
a disordered stomach causes severe headache, known as _sick headache_.
In many cases a few tablespoonfuls of hot water, taken at intervals of
five minutes, will effect a cure. He is himself "simple" who laughs at
this as "simple." If a dose of hot water _cures_, and removes any need
for expensive drugs, that is a matter for thankfulness and not for
laughter. When some substance not easily dissolved has lodged in the
stomach, hot water is often all that is needed to remove the trouble.
But it must be remembered that over-eating, or the eating of
indigestible food, must be given up, and the food must be masticated
till it is reduced to a liquid condition.

Many will say they have not time for this, but time must be taken, and
half the quantity of food well masticated will nourish better than the
whole imperfectly masticated.

Headache on waking in the morning is a frequent result of stomach
disorder. In such a case take two teacupfuls of hot water, with an
interval of ten minutes between. In many cases a slice of lemon in the
hot water powerfully aids to cure. Especially is this the case where
pains in the bowels are felt along with the headache. If lemons cannot
be had, a few drops of vinegar will form a good substitute. Continue to
