The sick room, if possible, should have a draught of air through it, day and night. The draught should not come directly upon the invalid. While burning fevers are raging, there is but little danger of taking cold. But especial care is needful when the crisis comes, and fever is passing away. Then constant watching may be necessary to keep vitality in the system. The sick must have pure, invigorating air. If no other way can be devised, the sick, if possible, should be removed to another room, and another bed, while the sick room, the bed and bedding are being purified by ventilation. If those who are well need the blessings of light and air, and need to observe habits of cleanliness in order to remain well, the sick are in still greater need of them in proportion to their debilitated condition.

A great amount of suffering might be saved if all would labor to prevent disease, by strictly obeying the laws of health. Strict habits of cleanliness should be observed. Many, while well, will not take the trouble to keep in a healthy condition. They neglect personal cleanliness, and are not careful to keep their clothing pure. Impurities are constantly and imperceptibly passing from the body, through the pores, and if the surface of the skin is not kept in a healthy condition, the system is burdened with impure matter. If the clothing worn is not often washed, and frequently aired, it becomes filthy with impurities which are thrown off from the body by sensible and insensible perspiration. And if the garments worn are not frequently cleansed from these impurities, the pores of the skin absorb again the waste matter thrown off. The impurities of the body, if not allowed to escape, are taken back into the blood, and forced upon the internal organs. Nature, to relieve herself of poisonous impurities, makes an effort to free the system, which effort produces fevers, and what is termed disease. But even then, if those who are afflicted would assist nature in her efforts, by the use of pure, soft water, much suffering would be prevented. But many, instead of doing this, and seeking to remove the poisonous matter from the system, take a more deadly poison into the system, to remove a poison already there. (2SM 460.2) MC VC

If every family realized the beneficial results of thorough cleanliness, they would make special efforts to remove every impurity from their persons, and from their houses, and would extend their efforts to their premises. Many suffer decayed vegetable matter to remain about their premises. They are not awake to the influence of these things. There is constantly arising from these decaying substances an effluvia that is poisoning the air. By inhaling the impure air, the blood is poisoned, the lungs become affected, and the whole system is diseased. Disease of almost every description will be cause by inhaling the atmosphere affected by these decaying substances. (2SM 460.3) MC VC
