The warm bath is perhaps, on the whole, more popular than the cold, since it is preferred usually by children and women, and is practiced by a considerable proportion of adult males. It is unquestionably somewhat enervating, and at best fails entirely to give the agreeable stimulation experienced by those who take a cold plunge. It is, however, to be preferred in those instances where cold water produces disagreeable effects, and if the bath be not too long continued it is followed by no ill results. Persons who become lean under cold baths not uncommonly take on flesh when they begin to use warm ones. It is unquestionably true that the latter is to be preferred in hot climates. The sea bath is invigorating not only from the water being cool, but as a consequence of the pleasurable excitement with which it is attended. Its greatest disadvantage lies in the fact that there is a tendency to overdo it, many persons remaining in the water for hours. Ten or fifteen minutes is as long as the average person should indulge in sea-bathing, and it is a question if even those who are young and vigorous should remain in the water longer than half an hour. Bathing of any kind should be indulged in before meals, the best time being before breakfast in the morning. _Care of the Teeth._--Nothing in connection with the subject of personal hygiene is of more importance than keeping the teeth properly cleansed. The fact is not generally appreciated that sound teeth stand in a most intimate relationship with good health, and that disastrous consequences are sure to follow sooner or later where these most important structures are neglected. While it is true that in a person of vigorous health one or two decayed teeth do not, as a rule, occasion obvious trouble at once, ill effects are sure sooner or later to be felt. For one thing, a person without good teeth cannot chew his food well. Those who begin by neglecting what at first are slight defects in the teeth seem to acquire in the course of time a sort of habit of doing this, and ultimately disregard and fail to have corrected the more serious diseases of the dental structures. Nothing is more common than for the practicing physician to find patients with one or more teeth partially gone, or, even worse, with only the exposed roots remaining. Where cavities exist, food is constantly forced into them, and undergoing decomposition, the breath of their owner becomes foul, and portions of decayed food mixed with multitudes of bacteria are constantly swallowed; sooner or later there inevitably follows under such circumstances catarrhal conditions of the stomach, which reaches a point in some individuals where the health is seriously threatened. Not only do bad teeth produce trouble in the way just mentioned, but there is every reason to believe that germs that produce disease--particularly those that cause consumption--not uncommonly find their way to the interior of the body through the resulting cavities.
