731. Morning exercise, walking in the free, invigorating air of heaven, or cultivating flowers, small fruits, and vegetables, is necessary to a healthful circulation of the blood. It is the surest safeguard against colds, coughs, congestion of the brain, inflammation of the liver, the kidneys, and the lungs, and a hundred other diseases.—The Health Reformer, September 1, 1868. HL 176.6
732. A walk, even in winter, would be more beneficial to the health than all the medicine the doctors may prescribe.... There will be increased vitality, which is so necessary to health. The lungs will have needful action; for it is impossible to go out in the bracing air of a winter's morning without inflating the lungs.—Testimonies for the Church 2:529. HL 177.1
733. The strength of the system is, in a great degree, dependent upon the amount of pure air breathed.—The Health Reformer, February 1, 1877. HL 177.2
734. In the cool of the evening it may be necessary to guard from chilliness by extra clothing, but they should give their lungs air.—Testimonies for the Church 2:527. HL 177.3
735. 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.—Testimonies for the Church 2:530. HL 177.4
736. Air is the free blessing of Heaven, calculated to electrify the whole system.—Testimonies for the Church 1:701. HL 177.5
