Outcome measures
Primary outcome
The main study parameter is the fraction of time spent relative to the thermoneutral zone. The distance from the thermoneutral zone is defined by comparing measured skin temperature and operative temperature to the theoretical centroid of the thermoneutral zone.
Secondary outcome
The secondary research questions relate to the primary objectives and aim to give insight in how the thermal states are related to physical and physiological parameters:
• Physiological
o Metabolic rate distinguished by:
• Basal metabolic rate
• Activity level
o Insulation distinguished by:
• Body composition
• Skin blood flow
• Physical
o Thermal environment by:
• Air temperature
• Humidity
• Clothing
• Subjective
o Thermal comfort
Study objective
This study aims to chart which thermal challenges modern day humans are exposed to and compare this to their thermoneutral zone. Therefore we hypothesize that modern day humans (both males and females) are predominantly within their thermoneutral zone
Study design
1 lab day and 2 field days
Intervention
During the field study subjects are encouraged to behave as they normally would, therefore no intervention is planned. During the laboratory visit the thermal environment of subjects is altered by changing clothing conditions while subjects perform several activities (sitting – walking) on a treadmill
