The wet-bulb globe temperature (WBGT) is a measure of environmental heat as it affects humans. Unlike a simple temperature measurement, WBGT accounts for all four major environmental heat factors: air temperature, humidity, radiant heat (from sunlight or sources such as furnaces), and air movement (wind or ventilation). [1]
The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.
Wet-bulb temperature and Wet Bulb Globe Temperature are used to determine the ability of a body to eliminate excess heat. A sustained wet-bulb temperature of about 35 °C (95 °F) can be fatal to healthy people; at this temperature our bodies switch from shedding heat to the environment, to gaining heat from it. [10]
What wet bulb globe temperature tells you about the weather. In hot temperatures, the human body typically creates sweat as a way to control body temperature through evaporative cooling. But in ...

‘Wet-bulb temperature’ refers to temperatures taken with a thermometer covered in a wet cloth, which are normally slightly cooler than ‘dry-bulb’ temperatures.
The wet-bulb globe temperature (WBGT) combines the effects of radiation (typically sunlight), humidity, temperature and wind speed on the perception of temperature.
At 100% relative humidity, wet-bulb temperature will be the same as the dry air temperature, but with less humidity it is lower. HOW DO HIGH WET-BULB TEMPERATURES AFFECT THE HUMAN BODY?
