Exercise in the Open Air—The whole system needs the invigorating influence of exercise in the open air. A few hours of manual labor each day would tend to renew the bodily vigor and rest and relax the mind.—Testimonies for the Church 4:264, 265 (1876). (1MCP 116.1) MC VC

Air, air, the precious boon of heaven which all may have, will bless you with its invigorating influence if you will not refuse it entrance. Welcome it, cultivate a love for it, and it will prove a precious soother of the nerves. Air must be in constant circulation to be kept pure. The influence of pure, fresh air is to cause the blood to circulate healthfully through the system. It refreshes the body and tends to render it strong and healthy, while at the same time its influence is decidedly felt upon the mind, imparting a degree of composure and serenity. It excites the appetite, renders the digestion of food more perfect, and induces sound and sweet sleep.—Testimonies for the Church 1:702 (1868). (1MCP 116.2) MC VC

Inactivity a Fruitful Cause of Disease—Inactivity is a fruitful cause of disease. Exercise quickens and equalizes the circulation of the blood, but in idleness the blood does not circulate freely, and the changes in it, so necessary to life and health, do not take place. The skin, too, becomes inactive. Impurities are not expelled as they would be if the circulation had been quickened by vigorous exercise, the skin kept in a healthy condition, and the lungs fed with plenty of pure, fresh air. This state of the system throws a double burden on the excretory organs, and disease is the result.—The Ministry of Healing, 238 (1905). (1MCP 116.3) MC VC
