Our Thermal Ergonomics Laboratory supports research focused on understanding the effects of physiological heat strain across the human lifespan and developing sustainable, evidence-based cooling solutions to keep individuals and communities safe.

Located within the Susan Wakil Health Building, the Thermal Ergonomics Laboratory helps inform policies, practices, and recommendations for individuals, communities, public health authorities, sporting bodies, industries, and government organisations - ultimately contributing to greater heat resilience during hot weather and extreme heat events.

Our state-of-the-art climate chamber can simulate environmental conditions of the past, present, and future. The climate chamber allows precise control of ambient temperature, humidity, airflow, and solar radiation — key environmental factors that influence human heat strain.

Capabilities of the Thermal Ergonomics Laboratory:

  • data acquisition systems for real-time monitoring of thermophysiological responses to extreme climates, including but not limited to local sweat rate, local skin blood flow, and core and skin temperature.
  • ultrasound machines capable of performing both cardiac and foetal ultrasounds, enabling the study of cardiovascular responses to heat exposure, and fetal monitoring for our studies on extreme heat and pregnancy,
  • water-perfused suits, which allow researchers to precisely control skin temperature by circulating water at specific temperatures through a network of tubing,
  • wireless ibuttons, skin temperature sensors, and telemetric pill monitoring to record real-time skin and core temperature responses,
  • COSMED metabolic systems for measuring cardiorespiratory responses, including oxygen consumption during rest and exercise,
  • hydration assessment tools,
  • lode exercise equipment, including recumbent ergometers, upright cycle ergometers and treadmills,
  • the capability to conduct overnight studies, which includes the ability to monitor sleep and brain activity (EEG), through our NOX polysomnography systems,
  • capability to conduct research on the combined impacts of bushfire smoke and extreme heat, and
  • capability to mimic occupational settings, such as ready-made garment factories, to better understand the impacts of heat and health on performance across a different work environment.

Research activity themes

Research activities conducted within the Thermal Ergonomics Laboratory largely fall within the following themes:
  • maternal and child health,
  • physical activity, sport and occupational health,
  • ageing and chronic diseases,
  • landscapes and the built environment, and
  • humanitarian settings.

Laboratory activities

Within these themes, our laboratory supports an array of human-based studies, including, but not limited to:
Ìý
  • Understanding the upper limits of human survivability in extreme environmental conditions
  • Assessing thermoregulatory impairments of specific populations (e.g. elderly, children, individuals with MS, and individuals who are pregnant)
  • Developing evidenced-based policies for extreme heatÌý
  • Managing occupational heat stress exposure
  • Undertaking heat acclimatisation studies
  • Developing and assessing evidenced-based cooling solutions for individuals and communities
