When it comes to heat, the human body is remarkably resilient — it’s the humidity that makes it harder to cool down. A term we rarely hear about, the wet-bulb temperature reflects not only heat, but also how much water is in the air. As the sun heats up the air, the ground, objects and people, the human body will react in an effort to cool itself. The wet-bulb temperature that marks the upper limit of what the human body can handle is 95 degrees Fahrenheit (35 Celsius). The combination of warmer waters and increasing heat trends in Sonora are causing the wet-bulb temperatures to reach dangerous levels.
