It is of great importance to acquire a habit of drawing the breath deeply and slowly, so as to expand the lungs freely during ordinary breathing. This requires that the head and shoulders be thrown well back in walking, sitting, and standing, and that no clothing be worn tight round the ribs. Those engaged in sedentary or stooping occupations should especially attend to this advice. Great care should be taken to avoid the pressure of dress more upon one part of the body than upon another. For this reason "padding" is very objectionable. (See Appendix on the "Importance and Dangers of Rest in Consumption.")

All persons whose pursuits require the long continuance or frequent assumption of any particular position or movement of the body or limbs, should take every opportunity of changing it for an opposite position or movement.

Those whose occupation obliges them to maintain the erect posture for a number of hours each day, should take every opportunity of lying flat down, even if only for a few minutes at a time. They should also bear in mind that standing will not take the place of walking exercise. (See Rest and Change; Sleep; and Exercise.)
