n
ceaselessly, winter and summer, through open windows by night inspire
just as if one slept in the open air, a sort of ecstasy. Gush follows
gush, full of delightfulness, replacing the used-up air and purifying
the blood. It has oftimes been said to me, 'I open the windows the
moment I get out of bed;' to this I have uniformly replied, 'the moment
to open the window is before you get into bed, not when you get out of
it.' You cannot otherwise with entire certainty secure the benefit of
an ever ceaselessly renewed night air so all essential to the blood's
renewal and the maintenance of health.... With abundant night coverings
there is no shadow of risk. There is none of rheumatism, none of
bronchitis, in short no risk whatever. The only, the real risk, which
we incur, is that of closing our sleeping chamber windows, of debarring
ourselves of pure air during our repose."

Appetite.--Should be an indication that food in general or some certain
kind of food is needed by the body. Thus the appetite is the natural
test of the amount and kind of food required. Over-eating and
indulgence in stimulating foods and drinks, insufficient mastication
and bolting of the food (_see_ Over-eating, etc.) give us a false
appetite, thus causing over-eating once more. A return to a simple and
moderate diet will restore the natural appetite.

Air Bath.--This may with advantage to the health of the skin and body
in general, be indulged in every morning during some of the toilet
operations, such as shaving, or preferably, dumbell exercise or Swedish
gymnastics. If exercises are done in a nude condition the utmost
freedom for the muscles is obtained. In a short time a notable change
will be observed in the skin, which will lose its pasty appearance, and
become soft flesh and of a healthy colour. If possible have the bedroom
with windows facing the morning sun, so that the sunlight can also
shine in. There are many sanitaria on the Continent and in America
where this form of "bathing" is practised. Indeed, one of the great
benefits of sea-bathing (overlooked in this country) is the exposure of
the skin to air and light. Consequently if the weather and social
custom permits, as much time as possible should be spent after
immersion, lounging on the sand. A child's natural instinct leads it to
play about after its bath in the sea instead of coming at once to be
dressed.
