Catching cold while bathing is possible, but scarcely probable, if ordinary precautions are taken. It is very bad practice to permit children to use one another's handkerchiefs or the handkerchief of an adult. Certain children are predisposed to attacks of "cold in the head" or acute coryza or nasal catarrh (these being the medical names for this condition). Sometimes this is an inherited characteristic. There is no doubt, however, that most of these children acquire the habit by bad sanitary and hygienic surroundings. These children do not as a rule get enough fresh air. They are kept indoors most of the time in stuffy, overheated, badly ventilated rooms, unless the weather is absolutely perfect. The windows in their bedrooms are always kept closed, because they are "liable to catch cold." They are overdressed and perspire easily and as a result "catch cold." These conditions all tend to create an unhealthy condition of the nasal mucous membrane and of the throat, and this is rendered worse if the child lives in a damp, changeable climate, such as that of New York City. In these susceptible children the exciting cause of an attack may be trivial; exposure, cold or wet feet, inadequate head covering (as already pointed out), a draught of cold air even may excite sneezing and a nasal discharge; hence we have: Acute Nasal Catarrh (Acute Coryza, Acute Rhinitis, "Cold in the Head", "Snuffles").--Acute nasal catarrh may accompany measles, diphtheria, influenza, and whooping cough. Symptoms.--The onset is sudden with sneezing, and difficulty in breathing through the nose. In a few hours, or it may be not for a day or two, a mucous, watery, nasal discharge appears. There are redness and slight swelling of the nose and upper lip, caused by the discharge. There is no fever as a general rule except in very young infants, in whom the fever may be very high. The discharge interferes with the nursing and the child suffers from lack of nourishment. The inflammation may extend to the eyes and ears, causing painful complications, or to the throat and bronchi, causing hoarseness and cough. Less frequently we have disturbances of the digestive tract with vomiting, or diarrhea. The mild form of the disease lasts for two or three days, the severe form from one to two weeks. Repeated attacks are said to contribute to the production of adenoid growths.
