Predicting Sweat Losses and Core Temperature Elevations

Understanding the source of variability in whole-body and local sweating as well as core temperature elevations during exercise and/or exposure to the heat allows for the accurate prediction of maximum exposure times for athletes/workers and water requirement guidelines to ensure proper hydration.

Factors currently under investigation include:

  • The timeline and magnitude of natural physiological acclimatization that may or may not occur through daily activity in the summer months
  • The influence of VO2max (aerobic fitness) and both perceived and relative exercise intensity upon the distribution of local sweating as well as whole-body sweating and core temperature elevations
  • The independent effects of body mass, body surface area and body fatness on sweat gland density and activation and subsequently whole-body sweat losses and rises in core temperature
  • Changes in sweating and skin blood control and output following injuries (e.g. spinal-cord), surgical procedures (e.g. thorascopic sympathectomy) or health disorders (e.g. Multiple Sclerosis)
  • Comparisons in thermoregulatory control and capacity during exercise and/or heat exposure in children at various stages of development
