Abstract
In hot environments, exposure to sunlight lead to increased skin temperature, resulting in physical stress like higher heart rate, fatigue, and reduced sports performance. This impact is particularly notable in outdoor activities such as golf. A study investigated how clothing and sunscreen blocking near-infrared radiation (NIR) could affect the physical stress and performance. Ten healthy male golfers aged 18-22 were tested in hot conditions mimicking sunny summer weather. Tests are implemented under the following two conditions, control condition using regular clothing and UV-protective sunscreen, and a test condition using NIR radiation-blocking clothing and sunscreen. NIR blocking condition exhibited lower heart rate, reduced sweating compared to the control condition. The findings suggest that blocking NIR can alleviate physical strain and potentially enhance performance.
