hot bath is to be used as a cleansing agent while the cold bath is a
tonic exclusively. A regimen of this sort will usually be
satisfactory where one is taking a general system of exercise nearly
every day which will insure a certain amount of internal functional
activity. Note, however, that the cold bath, though of some value, is
not necessary, when following the hot-water-drinking regimen.

There has been much controversy as to whether or not cold baths are
really beneficial, since in some cases they have proved harmful. Under
such circumstances the failure to secure good results may have been due
to ignorance of the principles involved and to the lack of vitality
essential to reaction from the shock of the cold water. A great deal
depends upon the manner in which the cold bath is taken and the physical
condition of the individual taking it.

A cold bath is a strong stimulant to the entire circulatory system,
provided one can recuperate with a feeling of warmth immediately
thereafter. If this feeling of warmth does not follow, if you feel cold,
uncomfortable, nervous and trembling for some time after the bath, the
shock has been too severe and is not of advantage. Under such
circumstances it is better either to avoid the bath altogether or else
take more exercise in order more thoroughly to warm the body before
taking the bath. Usually if one is warm before bathing and if the cold
bath is taken in a warm room it is easy to recuperate from it.
Another good suggestion in a case of this kind is to decrease the
duration of the bath. Do not stay in the water too long. In some
cases what is sometimes called a hand bath may be advantageous. This
bath is taken by merely wetting the hands several times in the
water and applying the moist palms to all parts of the body. The
familiar sponge bath, so-called, using either a sponge or a washcloth,
is often advised, although the hand bath just mentioned is even easier
to take.

I have also frequently recommended the use of the dry friction bath,
following exercise, as a means of preparing the body for a cold bath.
I have already referred to these dry friction rubbings as a means of
accelerating the activity of the skin. This friction bath will, in
nearly all cases, warm the skin sufficiently to enable one thoroughly to
enjoy the cold water. In fact, this friction is to a cold bath what
appetite is to eating. You should enjoy your meals and you should e
