The half bath is much the same as the full bath. A smaller tub is
required, as the bather sits upright with his limbs extended. The water
should be at least a foot deep. During the bath, the body should be well
rubbed, and water should be poured over the upper portion of the body.
Its general effects are nearly the same as those of the full bath, and
it may be used for the same general purposes. A little more vigorous
rubbing is required to prevent chilling, as so large a portion of the
body is exposed. It affords a better opportunity for stirring up the
bowels and abdominal viscera by shaking, percussing, and kneading the
abdomen.
