Sitting (or Sitz) Bath.--This bath, in whatever form administered, is essentially a sitting in cold water with the feet out. The feet, in fact, are better to be warmly covered up while the patient sits in the bath. The most important thing to be considered in all such baths is the degree of vitality possessed by the patient. If he has much vitality, then the bath may be deep and longer continued--as long as even forty minutes. If the vitality be low, the bath must be brief and very shallow--it may be even necessary to make it as short as _one minute_, or even less. In some cases, as a beginning, a mere dip is all that is required. This leaves a large discretion to the nurse, and is a matter which common sense should be able to decide. To try a short bath first, and repeat it several times, rather than to give one long one, is the safest plan. It will soon be found out how much the patient can bear. If the vitality be so low as to make the simple sitz-bath a danger, the feet may be immersed, for the one or two minutes of the bath, in a small bath of hot water, and the patient well wrapped up all over in warm blankets. In some cases it is necessary to _pour_ cold water on relaxed organs, which, especially with females, will sometimes not be braced up by mere immersion. But such pouring must be done with caution. Half-a-minute of it is _a long time_; one quarter-of-a-minute or less will usually be enough, even in important cases. If longer applications have only done harm, then let our friends try the one-minute bath, or the quarter-minute stream of water. In many cases we have known this make all right. Such short baths may be taken twice or thrice a day. Skin, Care of.--Among the vast majority of people air and water far too seldom touch the skin. Want of water makes it unclean, and want of water and air make it slow in reaction. Now, a healthy skin is of the utmost value when one is attacked by disease. It can regulate the temperature of the various organs, and the application of heat or cold to it will cause a reaction at once. Much of our treatment as given in this book is directed towards stimulating the action of the skin. It is obvious that in health as in disease the skin can and does so act on the internal organs. It should be the aim of everyone that this most important part of the body should receive careful attention by a strict watch on the diet, by cleanliness, tonic water baths (cold, tepid, shower, as may be found to suit), and by tonic air baths. Light clothing and porous underwear will also be found of use. We have already drawn attention to the value of Kneipp linen as the most suitable form of underwear (_see_).
