Visual and Auditory Vigilance During Exposure to Hot and Humid Conditions

Many studies have reported physiological and cognitive decrements following heat stress. Of particular concern in cricket are the possible negative effects of sustained protective helmet use, as this leads to an increase in heat-related stress. Correct and rapid decision making, and focused attention are essential for efficient performance whilst batting, and it is possible that helmet usage could impair such processes. In a repeated-measures, randomized crossover study, physiological, self-report, and cognitive measures were taken from 16 teenage cricketers before and after moderately intense (batting) exercise. Participants underwent the assessments twice, once while wearing a standard protective helmet, and again, when not wearing a helmet (counterbalanced). While helmet use did not lead to significant physiological changes, wearing a helmet led to some cognitive impairments in attention, vigilance and reaction times. These preliminary findings could have significance for cognitively demanding sports (and perhaps military and industrial settings) in which participants perform cognitively demanding operations under conditions of physical exercise whilst wearing protective helmets. Additional factors of hydration, exercise duration, and helmet design are discussed.

“…Azer et al (42) reported central tracking and peripheral reaction-time decrements for subjects at a temperature of 35°C and high humidity, although low humidit y at 35°C and moderate humidity at 37.8°C did not cause any change in performance. Bell et al (43) reported more missed signals (29.5-58°C dry bulb, different body temperatures) but no vigilance deficits. Bell (44) reported temperature effects of 35 versus 22°C (but not versus 29°C) on a secondary number processing task, but not on the primary pursuit-rotor task .…”

There is evidence that the thermal stress encountered in many work environments may negatively affect various aspects of human performance and behavior. Evaluation of the empirical research is, however, complicated by differences in both the methodology and the definition of the basic stimulus. Effects of heat and cold stress are briefly reviewed, with particular regard to theoretical considerations.Key terms: cold, heat, performance, social behavior.People are subjected to thermal stress in many work environments, as, eg, in outdoor work under intemperate climatic conditions or in the processing of products which require heat-producing technology or strict hygienic standards. While physiological limits of endurance are seldom reached in today's work environment, increasing interest is being focused on the possible negative effects on behavior. A relationship between thermal stress and accident occurrence was documented over 50 years ago, and a similar relationship to unsafe work behavior was recently demonstrated (1). These relationships form a background to the following discussion of the central issues in research on the behavioral effects of thermal stress.
