In order to have good health, we must have good blood; for the blood is the current of life. It repairs waste and nourishes the body. When supplied with the proper food elements and when cleansed and vitalized by contact with pure air, it carries life and vigor to every part of the system. The more perfect the circulation, the better will this work be accomplished.
MH 271.2 At every pulsation of the heart the blood should make its way quickly and easily to all parts of the body. Its circulation should not be hindered by tight clothing or bands, or by insufficient clothing of the extremities. Whatever hinders the circulation forces the blood back to the vital organs, producing congestion. Headache, cough, palpitation of the heart, or indigestion is often the result. MH 271.3
RespirationIn order to have good blood, we must breathe well. Full, deep inspirations of pure air, which fill the lungs with oxygen, purify the blood. They impart to it a bright color and send it, a life-giving current, to every part of the body. A good respiration soothes the nerves; it stimulates the appetite and renders digestion more perfect; and it induces sound, refreshing sleep. MH 272.1
The lungs should be allowed the greatest freedom possible. Their capacity is developed by free action; it diminishes if they are cramped and compressed. Hence the ill effects of the practice so common, especially in sedentary pursuits, of stooping at one's work. In this position it is impossible to breathe deeply. Superficial breathing soon becomes a habit, and the lungs lose their power to expand. A similar effect is produced by tight lacing. Sufficient room is not given to the lower part of the chest; the abdominal muscles, which were designed to aid in breathing, do not have full play, and the lungs are restricted in their action. MH 272.2
Thus an insufficient supply of oxygen is received. The blood moves sluggishly. The waste, poisonous matter, which should be thrown off in the exhalations from the lungs, is retained, and the blood becomes impure. Not only the lungs, but the stomach, liver, and brain are affected. The skin becomes sallow, digestion is retarded; the heart is depressed; the brain is clouded; the thoughts are confused; gloom settles upon the spirits; the whole system becomes depressed and inactive, and peculiarly susceptible to disease. MH 273.1
The lungs are constantly throwing off impurities, and they need to be constantly supplied with fresh air. Impure air does not afford the necessary supply of oxygen, and the blood passes to the brain and other organs without being vitalized. Hence the necessity of thorough ventilation. To live in close, ill-ventilated rooms, where the air is dead and vitiated, weakens the entire system. It becomes peculiarly sensitive to the influence of cold, and a slight exposure induces disease. It is close confinement indoors that makes many women pale and feeble. They breathe the same air over and over until it becomes laden with poisonous matter thrown off through the lungs and pores, and impurities are thus conveyed back to the blood. MH 274.1
When sickness comes, it is essential that we employ the varied agencies which, in co-operation with nature's efforts, will build up the body and restore the health. There is, also, a larger and more vitally important question—that of our relationship to God who originally gave man his life, who made every provision for his continued happiness, and who today is interested in his welfare.
In The Ministry of Healing by Ellen G. White, the author, a woman of large experience in the practical affairs of life, and one particularly favored with rare insight and knowledge, has brought within the reach of every father and mother, every man and woman, lay and professional, a vast fund of information on life and its laws, on health and its requisites, on disease and its remedies, on the sickness of the soul and healing.
