Deep breathing can also with great benefit be combined to some of these exercises in the same way as explained under the detailed description of the massage exercises. SUPPLEMENT HOW THE EXERCISES MAY BE UTILIZED IN SOME DISEASED AND DISORDERED CONDITIONS OF THE BODY The massage exercises and deep breathing exercises may be used with benefit in certain stages of different diseases. This should, of course, be done only on the recommendation of a physician. Inasmuch as the same disease does not attack all people to the same degree, it is, of course, impossible to state exactly when or at which stage of a disease the patient might begin to practice the exercises. Neither can it be said precisely how long an exercise or performance shall last in each case; it will vary from five to twenty minutes. This is a matter for the family physician to decide; however, the following hints may be in order. If the use of the exercises practiced moderately is recommended, begin them slowly for five or ten minutes daily (or as long as advised by the doctor) with a light pressure of the hands, and continue thus for several days. The exercises can then be made more vigorous by increasing the pressure of the hands to a moderate or stronger degree. The time can then likewise be increased to fifteen or twenty minutes in proportion to the improvement in the condition and strength of the performer. It is not meant to imply that it is necessary to immediately hurry to a doctor or hospital when disorders of a mild character occur; for instance, a slight pain or stiffness in the muscles of one of the limbs or other part of the body, a headache, obesity without complications or slight constipation. If three or more massage exercises are recommended for one performance, a general deep breathing exercise can likewise be practiced between each of those. Here may be noted, especially for the interest of physicians, the particular exercises which are most suitable for use in various diseases. There are other conditions than the ones mentioned below, in which the exercises might be used with benefit, but the following are the most important: Anaemia Headache Disorders of the Digestive System Disorders of the Liver Diabetes Affections of the Lungs Disordered Conditions of the Heart Insomnia Muscular Disorders Nervous Diseases Obesity Curvature of the Spine ANAEMIA All the massage exercises may be practiced once or twice daily. In addition, all the deep breathing exercises may be done separately, without strain, for five or ten minutes, twice daily. HEADACHE Here special reference is made to massage exercise No. 1, although all the exercises will prove of indirect benefit. DISORDERS OF THE DIGESTIVE SYSTEM (_Constipation—Gas in the Stomach—Stasis—Dilatation of the Stomach—Chronic Dyspepsia—Deficient Peristaltic Action, etc._)
