Wet bulb globe temperature measures heat stress in direct sunlight, giving a better idea of how the human body will react in hot and humid weather.
WBGT readings, unlike regular temperature readings, combine the effects of:
-
air temperature
-
wind speed
-
relative humidity
-
sun angle
-
cloud cover (solar radiation)
By taking in these other factors, WBGT is a more practical, accurate, and useful measurement of heat as it relates to the body, especially when dealing with outdoor activities and sports programs.
