“…However, AT (requiring only standard meteorological data) and PET appear to be more universal indicators in heat- and cold-related mortality assessments. Such findings need to be further investigated for other regions and populations, and they are important for determining the final procedure for cold exposure assessment within the UTCI calculation [4,59]. …”

We compare the recently developed Universal Thermal Climate Index (UTCI) with other thermal indices in analysing heat- and cold-related effects on cardiovascular (CVD) mortality in two different (urban and rural) regions in the Czech Republic during the 16-year period from 1994–2009. Excess mortality is represented by the number of deaths above expected daily values, the latter being adjusted for long-term changes, annual and weekly cycles, and epidemics of influenza/acute respiratory infections. Air temperature, UTCI, Apparent Temperature (AT) and Physiologically Equivalent Temperature (PET) are applied to identify days with heat and cold stress. We found similar heat effects on CVD mortality for air temperature and the examined thermal indices. Responses of CVD mortality to cold effects as characterised by different indices were much more varied. Particularly important is the finding that air temperature provides a weak cold effect in comparison with the thermal indices in both regions, so its application—still widespread in epidemiological studies—may underestimate the magnitude of cold-related mortality. These findings are important when possible climate change effects on heat- and cold-related mortality are estimated. AT and PET appear to be more universal predictors of heat- and cold- related mortality than UTCI when both urban and rural environments are of concern. UTCI tends to select windy rather than freezing days in winter, though these show little effect on mortality in the urban population. By contrast, significant cold-related mortality in the rural region if UTCI is used shows potential for UTCI to become a useful tool in cold exposure assessments.

UTCI—Why another thermal index?

19The existing assessment procedures of the thermal environment in the fields of public weather 20 services, public health systems, precautionary planning, urban design, tourism & recreation 21and climate impact research show significant shortcomings. This is most evident for simple 22 (mostly two-parameter) indices, when comparing them to complete heat budget models 23 developed since the 1960s. ISB Commission 6 took up the idea to develop a Universal 24 Thermal Climate Index (UTCI) which was to be based on the most advanced multi-node 25 model of thermoregulation representing the progress in science within the last 3 to 4 decades, 26 both in thermo-physiological and heat exchange theory. (FPC) was adopted for this study. The model was extensively validated applying as yet 5 unused data from other research groups, and extended for purposes of the project. This model 6 was coupled with a state-of-the-art clothing model considering the behavioural adaptation of 7 clothing insulation by the general urban population to actual environmental temperature. 8 UTCI was then derived conceptually as an Equivalent Temperature (ET). Thus, for any 9 combination of air temperature, wind, radiation, and humidity (stress), UTCI is defined as the 10 air temperature of the reference condition which would elicit the same dynamic response 11 (strain) of the physiological model as the actual conditions. As UTCI is based on 12 contemporary science its use will standardize applications in the major fields of human 13 biometeorology thus making research results comparable and physiologically relevant. 14 15

“…UTCI procedure is in good agreement with the assessment of other standards (heat budget, two-node and multi-node thermo-physiological models) concerned with the thermal environment [222]. Bearing in mind that objectives and underlying assumptions may differ when comparing ergonomics standards, the utility of the UTCI procedure for cold exposure quantification remains to be confirmed [220]. To date, local cooling of exposed skin including frostbite risk (wind chill effects), should be best regarded as a transient, rather than a steady-state phenomenon [223][224][225].…”

“…The published literature on its development include a clothing model [214,215], a multi-node physiological model [216] (for better fitting under all metabolic rates, including very high activity levels), a single-sector thermo-physiology, consisting of a sweating heated cylinder "Torso" [217], followed by a validation and time efficient operational procedure, a regression approach based computerization [218], and assessment in real setting [219]. In particular, the UTCI meets the following requirements: (i) Thermo-physiologically responsive to all modes of heat exchange between the body and its environment; (ii) Applicable for whole-body but also for local skin cooling (frostbite) (see [220]); (iii) Valid in all climates, seasons, and time and spatial scales; and (iv) Effective for a wide range of exercise intensities [214].…”

Given the climatic changes around the world and the growing outdoor sports participation, existing guidelines and recommendations for exercising in naturally challenging environments such as heat, cold or altitude, exhibit potential shortcomings. Continuous efforts from sport sciences and exercise physiology communities aim at minimizing the risks of environmental-related illnesses during outdoor sports practices. Despite this, the use of simple weather indices does not permit an accurate estimation of the likelihood of facing thermal illnesses. This provides a critical foundation to modify available human comfort modeling and to integrate bio-meteorological data in order to improve the current guidelines. Although it requires further refinement, there is no doubt that standardizing the recently developed Universal Thermal Climate Index approach and its application in the field of sport sciences and exercise physiology may help to improve the appropriateness of the current guidelines for outdoor, recreational and competitive sports participation. This review first summarizes the main environmental-related risk factors that are susceptible to increase with recent climate changes when exercising outside and offers recommendations to combat them appropriately. Secondly, we briefly address the recent development of thermal stress models to assess the thermal comfort and physiological responses when practicing outdoor activities in challenging environments.
