Great benefit may be derived by following these suggestions when the nature of the disease is not such as to forbid it. EXERCISE and rest necessarily alternate with each other. Exercise, so necessary to health, in many forms of disease greatly contributes to recovery. It sends the sluggish blood coursing through the veins and arteries with increased force and rapidity, so that it reaches every part of the system, supplying it with nourishment. It increases the waste of old material and creates a demand for new. Convalescing patients, or those suffering from chronic diseases, whenever the weather will permit, should take exercise every day in the open air. This should be done with regularity. The amount of exercise must be regulated by the strength of the patient; never take so much as to produce fatigue, but, as the strength increases, the exercise may be increased proportionately. Some interesting employment, commensurate with the patient's strength, should be instituted, so that the mind may be agreeably occupied with the body. When unable to take active exercise, the invalid, properly protected by sufficient clothing, should ride in a carriage or boat, and each day a new route should be chosen, so that a change of scenery may be observed, thus arousing new trains of thought, which will be exhilarating and prove beneficial to him. SEXUAL INFLUENCES. During the progress of disease or convalescence, entire continence must be observed. It is then necessary that all of the vital energies should be employed in effecting a recovery from disease, without having the additional tax imposed of overcoming the debilitating effects of sexual expenditure. This holds true with regard to all diseases, and especially those of the nervous system and genitourinary organs. VISITING THE SICK may be productive of good or evil results. Mental impressions made upon the sick exert a powerful influence upon the termination of disease. The chances of recovery are in proportion to the elevation or depression of spirits. Pleasant, cheerful associations animate the patient, inspire hope, arouse the vital energies, and aid in his recovery; while disagreeable and melancholy associations beget sadness and despondency, discourage the patient, depress the vital powers, enfeeble the body, and retard recovery.
