The organs of the child are peculiarly susceptible to the effects of overwork and fatigue; the entire body is in the process of development and its development may be retarded and its growth seriously hindered. It is a most excellent thing to keep the child employed and active, but there certainly should be a means of protecting him from the avarice and greed of heartless employers. The best way to do this is to keep him out of gainful employment until there has been sufficient physical development to insure against overtaxing the young body. Place of Work The influence of the occupation upon health will be governed not only by the character of the work, but also by the environment in which the work is performed. Whether it is indoor or outdoor work, whether it is an active or sedentary occupation, and whether there are extremes in the temperature, humidity, air pressure or light, or whether the work is on the surface or below it as in mines, are all factors. The position of the worker, the length of the working hours, the physical, mental and nervous strain all have a bearing on health. Outdoor work is preferred, especially for those who are inclined to pulmonary or respiratory disorders, because of the difference in the purity of the air. Outdoor workers suffer less from fatigue and their mortality rate is lower. Effect of Posture Posture of the workman is not without its effect upon the health and its bearing upon industrial hygiene is very important. There are many conditions that have their beginning in the occupation, such as faulty development of different parts of the body, curvatures of the spine, and especially those which are adaptative. Many subluxations are produced by posture assumed during long hours of work. In analyzing such cases chiropractically, the history of the occupation and the posture assumed should be carefully considered so that in adjusting the subluxated vertebrae there may be no opposition to the adaptative processes of Innate Intelligence in her endeavor to compensate for the faulty posture. Sedentary occupations such as typing, bookkeeping, shoe-making, engraving and tailoring result in lack of muscular activity and produce characteristic occupational disorders and deformities. It is not natural for an individual to remain in any one posture for the greater part of the day. Innate needs to have the body more or less active so that the proper adaptative processes can be carried on within the body. Sitting constantly at a desk will create a tendency to stooped shoulders and thus cramp the respiratory organs. The result will be a lack of proper oxygenation of the blood which will have its effect upon the metabolic processes of the body. There will be a sluggishness of the liver and other vital organs, and a tendency to anemia, constipation, general lack of muscular tone and low vitality.
