A dangerous combination of soaring temperatures and oppressive humidity can make it nearly impossible for the human body to regulate its temperature. Imagine a sauna where the heat and humidity keep rising. Eventually, the body reaches a point where sweating can no longer effectively cool itself down. This can lead to heatstroke, organ failure, and even death within hours. A wet-bulb thermometer measures both heat and humidity. When the wet-bulb temperature reaches a critical level, around 35°C,
