[Body function and the biological aging of those working under the conditions of a warming microclimate].

The state of the cardiovascular system, indices of thermoregulation, immunological reactivity, cardiopulmonary and biological age were investigated in workers of "hot" professions. It was established that persons working in conditions of heating microclimate show a weakening of the compensation capacities of the cardio-vascular system manifested in a reduction of tone of arterial vessels, inhibition of immunological reactivity. These workers revealed an increased rate of aging of the body at working length over 15 years.
