Acute respiratory diseases weaken bodily resistance to factors of industrial environment and activities. In subjects with vago- and normotonic type regulation, high level of adaptive capability permits the overstrain states to be avoided during the first post-illness days. The whole process of minimization of cost of the primary reaction of an organism gets completed by the end of the first week. In 80 percent of miners with sympathetic type vegetative dysbalance, industrial activities at week I are accompanied by a surplus vegetative maintenance. The process of readaptation to work gets protracted by 2 to 4 weeks, which fact attests to the need for such miners to be assigned to those jobs for which they are best suited and for dispensary health promotion in a mine's health-station setting.
