The movements of the body and arms and hands in applying the massage movements, exercise the muscles and nerves of the arms, the shoulders, the upper and lower back, the sides and the abdomen. This also influences the kidneys. The massage influences the muscles and nerves of the chest and the sides, likewise, the heart, the liver and lungs. _Effects of Exercise No. 14 A_ In No. 14 A the rolling exercises the muscles and nerves of the abdomen and lower sides to a greater extent than does the turning in exercise No. 14. PROPER BREATHING Nothing is more important than breathing for maintaining life, and it should be given much more attention than is customary. This may be done not only by practicing the special and general breathing exercises for several minutes one or several times daily, but also by acquiring the habit of proper breathing all the time. It is a curious fact that when the stomach is in need of more food, it is filled and sometimes to excess, but although the lungs are always in need of more air, they are mostly only filled about one-half and not completely, and this in spite of the fact that air is one of the few gifts of life. In order that the reader may notice the effect of proper natural breathing and to acquire the habit, it may be advisable to try the following experiment: Place a watch nearby. Breathe slowly, deeply and regularly for one or several minutes, inhaling the air each time through the nose and exhaling it either the same way or through both nose and mouth simultaneously. From twelve to sixteen respirations should be done per minute. Try occasionally to breathe with the diaphragm, that is, instead of first allowing the chest to expand, when inhaling, push the abdomen and diaphragm out first during the beginning of the inhalation and the chest during the latter half part of it. This is beneficial for all the digestive organs and their nerves. The most important thing is to breathe deeply, so that the air also reaches the bottom or points of the lungs. Of course, twelve or sixteen respirations can be taken per minute and the lungs become only half-filled just the same. This will not be of any benefit. On the contrary, it might cause anaemia, and its accompanists, such as neurasthenia, melancholia, fear, etc. Breathing in the right way will produce better blood, more nerve power, and last, but not least, a good humor. Apropos humor,—there are authors who, now and then in the titles of their books or articles, admonish one to be cheerful, to laugh and smile so as to avoid illness. Further perusal of the text, however, will show that they admit that this depends chiefly upon the physical condition, and they advise the practice of exercises, in order to make people physically fit first. This is, of course, true, since it is difficult for most people to be of a good disposition and smile and laugh when the body is not in fit condition. SPECIAL AND GENERAL DEEP BREATHING EXERCISES
