The Effect of The Hat Material, Color, and Shape on Physiological Indicators as Well as Temperature and Humidity Inside The Hat During Sports Activities in A Hot Environment
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.42 Vol.42】
ABSTRACT
The purpose of this study is to examine the hat-wearing effect, which was often verified in the laboratory, in actual exercise and sports situations in a hot environment, and to present basic data for the development of hats that could be useful to combat heat stroke. In Test 1, 39 different colors and materials were examined to find what would keep the temperature inside the hat low. As a result, multi-colored cotton poly blend had the lowest temperature rise. In Test 2, two types of hat were made of cotton poly material. These hats were used to observe changes in the temperature and humidity inside the hat as well as the core body temperature of the participant during 4kinds of sport activities. As a result, the wide vented hat had the lowest humidity rise. On the other hand, a hat with 1cm square small windows entirely was able to keep the increase rate of temperature inside the hat low by more than 15 points compared to the one with wide vent. The two types of hats were found to be superior to each other, suggesting that a sports cap with a combination of these would be highly useful.
