Cold bathing, by those affected with kidney trouble, is not advisable,

but delicate individuals, who cannot react well to the cold bath, can
greatly increase their resistance by graduated cool bathing performed as
follows: Standing in about a foot of hot water, one may rub the body

Cold bathing, by those affected with kidney trouble, is not advisable,
but delicate individuals, who cannot react well to the cold bath, can
greatly increase their resistance by graduated cool bathing performed as
follows: Standing in about a foot of hot water, one may rub the body
briskly with a wash cloth wrung out of water at about 80 degrees F. and
reduced day by day until it is down to 50 degrees F. Following this the
cold douche or affusion may be taken (water quickly dashed from a
pitcher) beginning at 90 degrees F. and daily reducing until
50 degrees F. is reached, or just before the point where an agreeable
reaction ceases to follow.
