Why are Wet Bulb Global Temperatures important? Heat stress and human safety Body's cooling mechanism : The body cools itself by sweating & evaporating that sweat. The wet bulb temperature is the key factor in how effective this process is. ☆ Dangerous conditions : When the wet bulb temperature gets too high around 35°C or 95° F, can be fatal because the body can no longer cool itself through sweating, even in the shade. ☆ Vulnerable populations : The elderly, young children, outdoor workers, homeless, and people with underlying health conditions are particularly at risk from high wet bulb temperatures.  ☆You Can Assess You Risk with simple Low Cost Tools Wet Bulb Temperature tools for everyday use, for everyone.  For under £30, a small battery powered digital thermometer / datalogger with blutooth and a smartphone app can provide relative humidity in % & temperature in Degrees Celcius or Farenheit. The app can provide graphical output.  IN...

  What are Wet Bulb Temperatures? Wet bulb temperature  measures the combined effect of heat and humidity, representing the lowest temperature achievable by evaporating water into the air .  It is measured using a thermometer with a water-soaked cloth over its bulb, and it always reads lower than or equal to the dry bulb temperature. A higher wet bulb temperature indicates higher humidity, which hinders evaporation and reduces the body's ability to cool itself through sweating. This makes it a critical metric for assessing heat stress on humans and is often higher than the commonly reported heat index. Why Wet Bulb Temperatures are important Humidity and Evaporation :  The wet bulb temperature is essentially a measure of how well water can evaporate into the air. Human Cooling : Our bodies cool through the evaporation of sweat. High wet bulb temperatures mean less evaporation, making it harder to cool down and leading to dangerous heat stress.   H...
