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.
