Designing and Manufacturing Cooling Pants and Evaluating Their Effects on Heat Strain in hot Laboratory Conditions

Heat exposure, as a work-related risk factor, can have a significant effect on human health. This study aimed to design and manufacture evaporative cooling pants and evaluate their effectiveness in reducing heat strain under controlled laboratory conditions.

The study consisted of three stages: developing evaporative cooling pants, assessing their cooling power in a laboratory and evaluating their effectiveness. 12 men wore regular pants and then switched to evaporative cooling pants while their heart rate, skin and ear temperature, and PSI were measured every 5 minutes. Data was analyzed using SPSS software.

The study revealed that the specially designed evaporative shorts lowered the temperature of the thigh skin by 3 °C (P < 0.05). However, there was no significant relationship between the two groups in terms of physiological parameters such as heart rate, ear temperature, and Physiological Strain Index (P > 0.05).

The use of designed evaporative cooling pants can have a positive impact on reducing skin temperature. However, it is recommended to test in actual work environments.
