Ineffectiveness of Water Mist Spray to the Upper Body of Healthy Adults in Suppressing Core Temperature Under Windless Environment.

ABSTRACT:

Background

Global warming has increased heat-related illness concerns. Water misting is used for workplace cooling, but its effect on core body temperature is unclear.

Methods

We examined whether spraying water mist on the upper body suppresses the increase in core body temperature in hot and humid environments. Nine healthy adult men exercised for 60 min on a bicycle ergometer at four metabolic equivalents under two conditions: warm-humid environment (30 °C ambient temperature [T_a], 85% relative humidity [RH]) and hot-dry (HD) environment (40 °C T_a, 30% RH). Water mist (MIST) or no mist (CON) was applied to the back of the head, neck, and dorsum of hands every 10 min.

Results

Rectal temperature changes were similar between conditions, but peak t
