711. Many suffer decayed vegetable matter to remain about their premises.... There is constantly arising from these decaying substances an effluvium that is poisoning the air. By inhaling the impure air, the blood is poisoned, the lungs become affected, and the whole system is diseased.—How to Live 4:61.HL 172.1

712. If a house be built where water settles around it, remaining for a time and then drying away, a poisonous miasma arises, and fever and ague, sore throat, lung diseases, and fevers will be the result.—How to Live 4:64.HL 172.2

713. Especially in wet seasons the sleeping-rooms become damp, and those who sleep in the beds are troubled with rheumatism, neuralgia, and lung complaints, which generally end in consumption.—How to Live 4:64.HL 173.1

Poor Ventilation

714. Many families suffer from sore throat, lung diseases, and liver complaints, brought upon them by their own course of action.... They keep their windows and doors closed, fearing they will take cold if there is a crevice to let in the air. They breathe the same air over and over, until it becomes impregnated with the poisonous impurities and waste matter thrown off from their bodies, through the lungs and the pores of the skin.—How to Live 4:63.HL 173.2

715. For invalids who have feeble lungs, nothing can be worse than an overheated atmosphere.—Testimonies for the Church 2:527.HL 173.3

716. The heated, oppressed atmosphere, deprived of vitality, benumbs the sensitive brain. The lungs contract, the liver is inactive.—Testimonies for the Church 1:702.HL 173.4

Improper Breathing

717. Stomach, liver, lungs, and brain are suffering for want of deep, full inspirations of air, which would electrify the blood and impart to it a bright, lively color, and which alone can keep it pure, and give tone and vigor to every part of the living machinery.—Testimonies for the Church 2:67.HL 173.5

Improper Use of the Voice

718. Speaking from the throat, letting the words come out from the upper extremity of the vocal organs, all the time fretting and irritating them, is not the best way to preserve health or to increase the efficiency of these organs.—Testimonies for the Church 2:616.HL 173.6

719. Careful attention and training should be given to the vocal organs. They are strengthened by right use, but become enfeebled if improperly used. Their excessive use will, if often repeated, not only injure the organs of speech, but will bring an undue strain upon the whole nervous system. The delicate harp of a thousand strings becomes worn, gets out of repair, and produces discord instead of melody.... It is not necessary to talk in a loud voice or in a high key; this does great injury to the speaker.... The human voice is a precious gift of God; it is a power for good, and the Lord wants his servants to preserve its pathos and melody. The voice should be cultivated so as to promote its musical quality, that it may fall pleasantly upon the ear and impress the heart. But the vocal organs are strangely abused, greatly to the injury of the speaker and the discomfort of the hearers.—Special Testimonies, Series A 7:9.HL 174.1

720. They injure the throat and vocal organs ... when it is not called for.... This is in consequence of the unnatural position of the body, and the manner of holding the head.—Testimonies for the Church 2:617.HL 174.2

721. Your dislike for physical taxation, while talking and exercising your throat, makes you liable to disease of the throat and lungs.... You should not let the labor come upon the upper part of the vocal organs, for this will constantly wear and irritate them, and will lay the foundation for disease. The action should come upon the abdominal muscles; the lungs and throat should be the channel, but should not do all the work.—Testimonies for the Church 3:311.HL 174.3

722. Many speak in a rapid way, and in a high, unnatural key; but if they continue such a practise, they will injure the throat and lungs, and as a result of continual abuse the weak and inflamed organs will become diseased in a serious way, and they will fall into consumption.—Christian Education, 125.HL 175.1

723. There is need that among our ministers careful attention should be given to the culture of the voice, or many will lie down in untimely graves.—Christian Education, 133.HL 175.2

Proper Use of the Voice

724. The proper use of the vocal organs will bring benefit to the physical health, and increase your usefulness and influence.—Christian Education, 132.HL 175.3

Improper Dress

725. The extremities are chilled.... The heart fails in its efforts, and the limbs become habitually cold; and the blood, which is chilled away from the extremities, is thrown back upon the lungs and brain, and inflammation and congestion of the lungs or the brain is the result.... If the limbs and feet could have the extra coverings usually put upon the shoulders, lungs, and heart, and healthy circulation be induced to the extremities, the vital organs would act their part healthfully, with only their share of clothing.HL 175.4

I appeal to you mothers, do you not feel alarmed and heart-sick by seeing your children pale and dwarfed, suffering with catarrh, influenza, croup, scrofulous swellings appearing upon the face and neck, inflammation and congestion of the lungs and brain? Have you studied from cause to effect? Leaving their arms and legs insufficiently protected has been the cause of a vast amount of disease and premature death.—How to Live 5:72.HL 175.5

726. It is essential to health that the chest should have room to expand fully, so that the lungs may be enabled to take full inspirations of air. Many who have died of consumption might have lived their allotted term of life had they dressed in accordance with the laws of their being. The strength of the system is, in a great degree, dependent upon the amount of fresh air breathed. If the lungs are restricted, the quantity of oxygen received into them is also limited, the blood becomes vitiated, and disease follows.—The Health Reformer, February 1, 1877.HL 176.1

727. The arms’ being naked exposes the infant to constant cold, and congestion of lungs or brain. These exposures prepare the way for the infant to become sickly and dwarfed.—How to Live 5:71.HL 176.2

Immoderate Eating

728. Catarrhal difficulties, kidney disease, headache, and heart troubles are the result of immoderate eating.—Unpublished Testimonies, August 30, 1896.HL 176.3

Liquor

729. By the habitual use of sour cider many bring upon themselves permanent disease. Some die of consumption or fall under the power of apoplexy from this cause alone.—The Review and Herald, March 25, 1884.HL 176.4

Drugs

730. Every poisonous preparation in the vegetable and mineral kingdoms, taken into the system, will leave its wretched influence, affecting the liver and lungs.—Spiritual Gifts Volume 4a, 140.HL 176.5
