| Humans in hot environments are exposed to health risks and thermal discomfort which seriously
affects their physical, physiological and mental workload. This study aimed to assess the effects
of using cooling vests (CVs) on physiological and perceptual responses at workplace. Three
main databases were searched using subject headings and appropriate Mesh terms. The article
has been written according to the PRISMA checklist. A total of 23,837 studies were identified
for screening and 63 studies were eligible for data extraction. A statistically significant
difference was observed in body temperature among hybrid cooling garments (HBCGs), phasechange materials (PCMs) and air-cooled garments (ACGs)) at 31.56-37 ºC (60% RH),
evaporative cooling garments (ECGs) at 25.8-28.1 °C, and liquid cooling garments (LCGs) at 35
°C (49% RH) compared without cooling vests (CON) condition (p<.001). HBCGs ((PCMs) and
(ACGs)) are effective means in hot, moderate, humid or dry environments. |
