	#* Wet bulb globe temperature (WBGT) is a measure of the heat stress in direct sunlight, which takes into account: temperature, humidity, wind speed, sun angle and cloud cover (solar radiation). This differs from the heat index, which takes into consideration temperature and humidity and is calculated for shady areas. It is used by industrial hygienists, athletes, sporting events and the military to determine appropriate exposure levels to high temperatures. While there are mobile apps, a handheld device will provide much more accurate local data.		#* Wet bulb globe temperature (WBGT) is a measure of the heat stress in direct sunlight, which takes into account: temperature, humidity, wind speed, sun angle and cloud cover (solar radiation).

==Heat guidelines==
We '''strongly recommend''' that kingdoms develop heat conventions/policies for their environment and activities.
#Definitions/Measurement types
#* Heat index is the measure of the temperature that a person feels, which is different from the actual air temperature, as it factors in humidity as well as air temperature. It might also be called the apparent temperature.

===Helpful resources===
The OSHA-NIOSH Heat Safety Tool App provides (note: this is only available in the USA):
*A visual indicator of the current heat index and associated risk levels specific to your current geographical location.
*Precautionary recommendations specific to heat index-associated risk levels.
*An interactive, hourly forecast of heat index values, risk levels, and recommendations for planning outdoor activities.
*Location, temperature, and humidity controls, which you can edit to calculate for different conditions.
*Signs and symptoms and first aid for heat-related illnesses.
