This study was to determine the main health-related reasons, age and occupation of those who took early retirement due to total work inability. This was done through an analysis of the data from Poland’s Social Insurance Institution (ZUS) from 2000 and 2001. An analysis of these data showed an increase in the number of certificates confirming total inability to work in people over 40 years old. Over 50% of certificates work were issued to workers in 2 age-groups: 45–49 and 50–54. Diseases of the circulatory system, musculoskeletal system and connective tissue as well as mental and behavioural disorders are the main causes of early inability to work. Approximately 70% of people who obtained certificates confirming total inability to work had blue- and blue-and-white-collar jobs.

The aim of the study was to compare heat strain among different age groups of men in protective clothing during short-term physical work. Eight young (20-29 years), 6 middle-aged (41-55 years), and 6 older (58-65 years) men exercised for 30 min on a cycle ergometer (40% VO2 max) in 2 hot environments with a similar WBGT (ca. 26 ºC): once with minimal clothing without infrared radiation (E1), and once with aluminized protective clothing under infrared radiation (E2). All subjects had sedentary jobs, but only the older subjects were physically active in their leisure-time. Body temperatures, heart rate, sweat rate, and subjective feelings were determined during the tests. Higher thermal strain was observed in E2 than in E1. No age-related differences in thermal strain were observed in either experiment indicating that active older men can tolerate short work periods with protective clothing in the heat as well as younger sedentary men.
