Most of us crave heat–whether it's in the form of food, weather, or energy. It can rejuvenate our minds or charge our bodies to take action. We travel to hot climates for some much needed vitamin D. Beachgoers soak up the rays while explorers trek through scorching deserts. Without the sun, it would be impossible for us to survive. Heat is the spark to our lives.
