Responses to Heat and Cold Stress

14.2K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Area of Science:

  • Environmental Physiology
  • Cognitive Science
  • Human Performance

Background:

  • Understanding how thermal stress affects cognitive function is crucial for optimizing performance in various environments.
  • Previous research suggests a link between elevated body temperature and impaired cognitive abilities, but specific thermophysiological and perceptual factors require further investigation.

Purpose of the Study:

  • To examine the relationship between changes in thermophysiological variables (gastrointestinal temperature, heart rate) and cognitive performance (accuracy, response time, time estimation) during passive heat stress.
  • To determine the influence of subjective measures (cognitive load, thermal perception) on cognitive task performance under heat stress.

Main Methods:

  • Young adult males underwent passive heat exposure via head-out water immersion at neutral (36.5°C) and warm (38.0°C) conditions for 60 minutes.
  • Cognitive tasks included a judgment task (accuracy, response time) and an interval timing task.
  • Physiological measures included gastrointestinal temperature and heart rate; subjective measures included NASA-TLX, exertion, thermal sensation, and comfort.

Main Results:

  • Gastrointestinal temperature and heart rate were significantly higher in the warm condition compared to the neutral condition.
  • Decreased accuracy in the cognitive task was significantly associated with increased gastrointestinal temperature, moderated by thermal sensation and heart rate.
  • Response time changes correlated with gastrointestinal temperature changes, while time estimation was best explained by thermal discomfort.

Conclusions:

  • Cognitive performance, including accuracy and time perception, is significantly associated with thermophysiological changes and thermal perception during passive heat stress.
  • While increased core temperature negatively impacts accuracy, physiological arousal (heart rate) and thermal sensation can attenuate these effects.
