_Increasing Natural Resistance by Augmented Healthfulness_ If there is any way of increasing the natural resistance against epidemic influenza, it is a most desirable goal toward which to work, but it must first be determined along what lines the effort is to be directed. It was not the aged, the unconditioned nor the physically unfit who suffered most from influenza, but was rather the best trained, most healthful and most robust young persons we had. Those in the army had been selected because of their physical fitness and they had further received excellent physical training in the various camps and cantonments. It would not be possible to bring any large percentage of the general public up to such a stage of “augmented healthfulness” as healthfulness is generally understood. It has been said that men in the military camps were more commonly infected because they were more active, went about more and were, therefore, more frequently exposed. In one particular this statement is true, for men marching rapidly and exercising violently breathe more deeply and at a faster rate than they do under ordinary conditions, so that they naturally draw greater quantities of air into their lungs. It was an obvious fact that those persons given to sedentary lives were less often affected than the active and vigorous. Practically speaking, it would seem that during influenza epidemics people should be instructed to take more than the usual amount of sleep and rest, to indulge only in mild exercises, to eat good, wholesome food, to wear warm clothing, to seek mental and physical relaxation at home, and, above all, to avoid crowds and public gatherings. In some instances the constant use of oils in the nose and throat was advised, the theory being that the oil served the double purpose of preserving the healthy condition of the mucous membranes by lessening crusting, crevicing and drying, and of mechanically protecting from infection by the presence of the layer of oil. Many of the different liquid paraffins, both medicated and in the natural state, were used. It is probably advisable to apply such oils either with a swab or from a medicine dropper, rather than to attempt to spray them, since in the latter method there is some danger of blowing infectious material down into the trachea and larynx. It is hardly necessary to point out the importance of augmented cleanliness of the mouth, teeth and throat by means of mild antiseptic washes and tooth-cleansing materials during an epidemic.
