Ultra Violet (UV) parasols are a reasonable countermeasure against heat stress as they portable and inexpensive. This study compared the mitigation effect of UV parasol with that street trees dry-mist spraying on hot humid summer day in Japan. We observed meteorological elements calculated universal thermal climate index (UTCI) wet-bulb globe temperature (WBGT) under parasol, trees, spraying, d...

A meta-analysis to mathematically summarize the eVect of hot and cold temperature exposure on performance was completed. The results from 515 eVect sizes calculated from 22 original studies suggest that hot and cold temperatures negatively impact performance on a wide range of cognitive-related tasks. More speci®cally, hot temperatures of 908F (32.228C) Web Bulb Globe Temperature Index or above...

This study aimed to investigate the thermal responses of acclimated workers exposed heat stress in a real work environment. The physiological indices and subjective perception 14 were measured an industrial plant. effects wet bulb globe temperature (WBGT) on studied. differences between unacclimated college students compared analyzed. relationship mean skin sensation was revealed. results show ...

OBJECTIVE: To assess whether ice-water immersion or cold-water immersion is the more effective treatment for rapidly cooling hyperthermic runners. DESIGN AND SETTING: 17 heat-acclimated highly trained distance runners (age = 28 +/- 2 years, height = 180 +/- 2 cm, weight = 68.5 +/- 2.1 kg, body fat = 11.2 +/- 1.3%, training volume = 89 +/- 10 km/wk) completed a hilly trail run (approximately 19 ...

To help making comfortable workplaces and to prevent health disorders induced by the exposure to moderate cold in two different groups of out-door workers, we conducted a survey to compare subjective symptoms and cold prevention measures in winter between traffic control workers and construction workers. The subjects of this study were 98 male traffic control workers and 149 male workers engage...
