Objectives

Narrative objectives1

Heat stroke may occur when body temperature rises excessively. To prevent heat stroke or recover from heat stroke, the elevated body temperature must be quickly lowered. One method of lowering elevated body temperature is cold water immersion. Carbonated water is more effective than tap water in lowering body temperature quickly because it promotes heat transfer through dilation and expansion of skin blood vessels. This study will serve as a basic research to establish a cooling method using carbonated water.

Basic objectives2

Others

Basic objectives -Others

Based on previous study, it is possible that the skin vasodilation effect of carbonated water immersion differs depending on the difference in skin temperature at the start of immersion (i.e., the degree of dilation of skin blood vessels). Therefore, this study examines the effects of differences in skin temperature at the start of immersion in a low-temperature carbonated water on skin blood flow during immersion.

Interventions/Control_1

After immersing the left forearm in tap water set at 40 degrees C for 5 minutes to increase skin temperature and dilate skin blood vessels, the left forearm is immersed in a carbonated water set at 25 degrees C for 15 minutes.

Interventions/Control_2

After immersing the left forearm in tap water set at 32 degrees C for 5 minutes to increase skin temperature and dilate skin blood vessels, the left forearm is immersed in a carbonated water set at 25 degrees C for 15 minutes.

Interventions/Control_3

After immersing the left forearm in tap water set at 25 degrees C for 5 minutes to increase skin temperature and dilate skin blood vessels, the left forearm is immersed in a carbonated water set at 25 degrees C for 15 minutes.
