New workers are vulnerable to heat-related illness because they have not acclimatized to working in the heat. Acclimatization is a physiological process that occurs when exposure to heat takes place gradually over an extended period. Once acclimatization is achieved, working in the heat results in production of a more dilute sweat (lower salt content) and […]
