ABSTRACT
Studies reveal that with exposure to a thermally uncomfortable working environment, workers will show signs of indisposition and fatigue, which reduces efficiency and increases the incidence of work accidents (Minett, et al., 2007). One of the possible causes of this is the fact that changes of temperature require an additional biological effort to re-balance homeothermic conditions, which exacerbates the feelings of discomfort and tiredness, with negative consequences for health and productivity (Almeida, 2010). Management plays a key role in implementing work breaks for staff, so as to minimize the effects of thermal fatigue which are frequently detected by thermal comfort evaluations (Silva, 2013).
