Investigation of Internal Body Cooling Effect Using Rapid Supercooling Method of Ambient Temperature Solution
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.43 Vol.43】
ABSTRACT
Prevention of dehydration and cooling of the body is important for the prevention of heatstroke. In recent years, the effects of ingesting an ice slurry have been reported as an innovative method to simultaneously achieve dehydration and body cooling. However, ice slurries are difficult to drink and to adjust to the needs of the subjects, so Theses issue need to be improved before they can be implemented in the field. In this study, as an approach to this implementation, we focused on the effect of supercooled water and conducted an experimental investigation. We also developed a method to rapidly cool the surrounding environment using supercooled water.
As a result, it was found that although the body cooling effect of supercooled water is not as good as that of ice slurry, it is easy to drink, has an immediate effect, and has a high possibility of preventing dehydration. On the other hand, theoretical considerations revealed problems in the development of a cooling method for ambient temperature solutions using endothermic reactions. The results of this study show the potential of supercooled water as a new body cooling tool.
