Heat Stress & WBGT FAQs
What is Wet Bulb Globe Temperature (WBGT)?
What is the difference between the Wet Bulb Globe Temperature and the Heat Index?
Wet bulb globe temperature in a nutshell is a more in-depth heat stress measurement taking into account more of the environment (Direct sunlight, water vapor capacity, cloud coverage, etc.). Read more about the differences between WBGT and the heat index here.
How does WBGT impact athletes?
Monitoring WBGT is essential for protecting athletes’ health and safety during outdoor practices, games, and events.
A higher WBGT reading leads to a greater risk of heat-related illnesses like heat stroke, heat exhaustion, and muscle cramps.
What is Heat Acclimatization?
Heat acclimatization is your body’s way of adapting to hot environments.
By gradually increasing your workload or exposure time in hot conditions over 1-2 weeks, you can significantly improve your heat tolerance.
This reduces the risk of heat stress and allows you to perform better in hot weather.
What is a Heat Illness?
There are two main ways heat illness can strike:
1. Classic Heat Illness: This is caused by your environment’s impact on your body’s ability to cool down. Think high temperatures, humidity, direct sun, and no breeze.
2. Exertional Heat Illness (EHI): This one focuses on your own internal heat production. It can happen even in mild weather if you push yourself too hard.
What is the science behind WBGT?
Wet bulb globe temperature involves measuring three temperatures: dry bulb, wet bulb, and globe. Read more here.
What is the difference between Heat Stress and Heat Illness?
Imagine heat stress as a warning light on your body’s dashboard. If heat stress isn’t addressed, it can progress to heat illness. This is a medical emergency where the body can no longer cool itself down effectively. It can be life-threatening if not treated promptly. Read more here.
How can I measure the WBGT? What is the best way to measure the wet bulb globe temperature?
To measure WBGT, use a scientifically approved WBGT meter. The best way to measure it is by using Perry Weather’s advanced weather monitoring platform.
