Summary, in English

The aim of the study was to identify whether a ventilated cooling shirt was effective in reducing heat strain in hot climate. 8 female volunteers (age: 26±5 years; height: 165±7 cm; body weight: 58±9 kg) were exposed in heat (38 °C, 45 % RH) for 2 hours with simulated office work. In the first hour they were in normal summer wears (total thermal insulation 0.7 clo); in the second hour a ventilated shirt was worn. After the shirt was introduced for one hour, the scapular and the chest skin temperatures were significantly reduced (p<0.05). The mean skin and the core temperatures were not significantly reduced. The subjects felt cooler and more comfortable by wearing the shirt, but the cooling effect was most conspicuous only during the initial 10 minutes. The cooling shirt reduced heat strain, but the cooling power was not very effective under the low body activity.
