Another warm day today, so here's some
#science. Sitting in the
#shade is not cooler than in the
#sun. The air is the same
#temperature. What makes a location in the sun feel warmer is due to objects—or yes, skin—absorbing and retaining direct radiant energy from the sun.
Also, we warm up a thin layer of air around us all the time; convection. Wind, a fan, or—shock horror!—moving will disperse this heated layer, allowing the air—which is generally cooler, unless the air temp approaches or is higher than body temperature—to cool you down. At blisteringly hot temps, the only thing your body can really do is thermoregulate itself through evaporation.
Being mostly in the shade, putting on a fan, and staying hydrated is good advice, but perhaps not for the reasons you think. Ultimately it’s not the sun, but your own body that makes you feel hot, and there are some simple solutions to make things More bearable, including the counterintuitive “moving”.
