People suffering from coughs, no matter how severe, should get out into the air regularly, if they have no fever, and should go on with their regular occupation unless that occupation is very confining or is necessarily conducted in dusty air. Keeping to the house only prolongs the affection and makes it much more liable to complications than would otherwise be the case. Sufferers from these affections should not go into crowds, should avoid the theaters and crowded cars, partly for the sake of others--because they can readily convey their affection to them--but also for their own sake, because they are more susceptible to other forms of bacteria than those already implanted in their own systems and they are much more liable to pick up foreign bacteria in crowds than anywhere else. They should be out in the open air, particularly in the sunlight, and this will do more to shorten the course of a cough and cold than anything else. {199} They need more sleep than before and should be in bed at least ten or eleven hours in the day, though if they should not sleep during all of that time, they need not feel disturbed but may read or knit or do something else that will occupy them while they retain a recumbent position. They should not indulge in long, tiresome walks and in special exertion, but should postpone these until the cough has given definite signs of beginning to remit. With regard to the cough itself, it must not be forgotten that the action of coughing is for the special purpose of removing material that needs to be cleared from the lungs and the throat and larynx. It should not be indulged in except for that purpose. It requires a special effort, and while the lungs and other respiratory passages are the subject of a cold, these extra efforts should not be demanded of them unless they are absolutely necessary. Almost needless to say, people indulge in a great deal of unnecessary coughing. Some of this is a sort of habit and some of it is due to that tendency to imitate, so common in mankind. Every one has surely heard during religious services, in a pause just after heads have been bowed in prayer or for a {200} benediction, a single cough from a distant part of the church which seemed to be almost the signal for a whole battery of coughs that followed immediately from every portion of the edifice. If some one begins coughing during a sermon or discourse, others will almost inevitably follow. Coughing, like yawning, is very liable to imitation.
