The season most to be dreaded by one going among these invalids is winter. It is winter indeed, not only outdoors, but in, to those who are compelled to live in the same house and sleep in the same room. These victims of a diseased imagination shut themselves indoors and close the windows, for the air affects their lungs and their heads. Imagination is active; they expect to take cold, and they will have it. No amount of reasoning can make them believe that they do not understand the philosophy of the whole matter. Have they not proved it? they will argue. It is true that they have proved one side of the question,—by persisting in their own course,—and yet they do take cold if in the least exposed. Tender as babies, they cannot endure anything; yet they live on, and continue to close the windows and doors, and hover over the stove, and enjoy their misery. They have surely proved that their course has not made them well, but has increased their difficulties. Why will not such allow reason to influence the judgment and control the imagination? Why not now try an opposite course, and in a judicious manner obtain exercise and air out of doors, instead of remaining in the house from day to day, more like a bundle of drygoods than an active being?

The chief if not the only reason why many become invalids is that the blood does not circulate freely, and the changes in the vital fluid, which are necessary to life and health, do not take place. They have not given their bodies exercise nor their lungs food, which is pure, fresh air; therefore it is impossible for the blood to be vitalized, and it pursues its course sluggishly through the system. The more we exercise, the better will be the circulation of the blood. More people die for want of exercise than through overfatigue; very many more rust out than wear out. Those who accustom themselves to proper exercise in the open air will generally have a good and vigorous circulation. We are more dependent upon the air we breathe than upon the food we eat. Men and women, young and old, who desire health, and who would enjoy active life, should remember that they cannot have these without a good circulation. Whatever their business and inclinations, they should make up their minds to exercise in the open air as much as they can. They should feel it a religious duty to overcome the conditions of health which have kept them confined indoors, deprived of exercise in the open air. (2T 525.2) MC VC

Exercise will aid the work of digestion. To walk out after a meal, hold the head erect, put back the shoulders, and exercise moderately, will be a great benefit. The mind will be diverted from self to the beauties of nature. The less the attention is called to the stomach after a meal, the better. If you are in constant fear that your food will hurt you, it most assuredly will. Forget self, and think of something cheerful. (2T 530.1) MC VC

Many labor under the mistaken idea that if they have taken cold, they must carefully exclude the outside air and increase the temperature of their room until it is excessively hot. The system may be deranged, the pores closed by waste matter, and the internal organs suffering more or less inflammation, because the blood has been chilled back from the surface and thrown upon them. At this time, of all others, the lungs should not be deprived of pure, fresh air. If pure air is ever necessary, it is when any part of the system, as the lungs or stomach, is diseased. Judicious exercise would induce the blood to the surface, and thus relieve the internal organs. Brisk, yet not violent exercise in the open air, with cheerfulness of spirits, will promote the circulation, giving a healthful glow to the skin, and sending the blood, vitalized by the pure air, to the extremities. The diseased stomach will find relief by exercise. Physicians frequently advise invalids to visit foreign countries, to go to the springs, or to ride upon the ocean, in order to regain health; when, in nine cases out of ten, if they would eat temperately and engage in healthful exercise with a cheerful spirit, they would regain health and save time and money. Exercise, and a free and abundant use of the air and sunlight,—blessings which Heaven has freely bestowed upon all,—would give life and strength to the emaciated invalid. (2T 530.2) MC VC
