“…This essentially confiied Nielsen's work; however Lind also found that, with higher effective temperatures than Nielsen had used, body heating increased rapidly and that the point at which this increase commenced was at a lower effective temperature for the higher work rates. Similar results were found in a later study by Kraning, Belding and Hertig [1966] where heat storage (as measured by rectal temperature) was found with air temperatures of 33°C. or greater.…”

Previous research on human functioning in the thermal environment is reviewed, and it is shown that a change or variation in intensity is a relevant aspect of the thermal environment, and that one way in which this change influences human functioning is through the level of arousal of the individual. Experiments were therefore carried out on the physical conditions in several ofices, all airconditioned to maintain temperature, relative humidity and air movement at the prescribed standards. The relationship of the thermal environment to the level of arousal and to physiological strain are discussed.

“…Although cardiac output was not increased by high ambient temperature when exercise required greater than 40%o of maximal oxygen consumption, demands for heat dissipation ultimately may become a primary stimulus for regulating cardiac output when exercise is mild and prolonged (15,16). However, longitudinal comparisons at normal and high ambient temperatures have not been made in a sufficient number of unacclimatized men.…”

“…As indicated above, our results should not be construed to apply to all intensities of work in the heat, since mechanisms of cardiovascular regulation may depend upon both the severity and duration of work. If, as limited evidence suggested (15,16), cardiac output is augmented by heat stress when circulatory requirements for oxygen transport are small, levels of work must have been attained at which metabolic demands upon the circulation either exceeded or took precedence over thermal requirements for heat transfer. Because our subjects were not in thermal balance and ambient water vapor pressure (22 mm Hg, 33% relative humidity) was sufficient at 43.3°C to prevent evaporation of all sweat, their total heat stress could not be determined.…”

The assessment of the risk of human exposure to heat is a topic as relevant today as a century ago. The introduction and use of heat stress indices and models to predict and quantify heat stress and heat strain has helped to reduce morbidity and mortality in industrial, military, sports, and leisure activities dramatically. Models used range from simple instruments that attempt to mimic the human-environment heat exchange to complex thermophysiological models that simulate both internal and external heat and mass transfer, including related processes through (protective) clothing. This article discusses the most commonly used indices and models and looks at how these are deployed in the different contexts of industrial, military, and biometeorological applications, with focus on use to predict related thermal sensations, acute risk of heat illness, and epidemiological analysis of morbidity and mortality. A critical assessment is made of tendencies to use simple indices such as WBGT in more complex conditions (e.g., while wearing protective clothing), or when employed in conjunction with inappropriate sensors. Regarding the more complex thermophysiological models, the article discusses more recent developments including model individualization approaches and advanced systems that combine simulation models with (body worn) sensors to provide real-time risk assessment. The models discussed in the article range from historical indices to recent developments in using thermophysiological models in (bio) meteorological applications as an indicator of the combined effect of outdoor weather settings on humans.
