Scientists Study Extreme Temperature Which Causes Humans to Spontaneously Die

An intense heat wave roasted many US states and cities, resulting to sudden deaths of people which scientists believe to be a cause of heat and humidity conditions. According to a 2020 study on emergence of heat and humidity, temperature during severe heat waves may reach to a certain condition called 'wet bulb' that can impose a physiological limit that a human body can no longer tolerate, eventually leading to an 'overheat'.
