Acidified dairy products like yogurt

Acidified dairy products act like a cold shower from the inside at high temperatures. Yogurt, quark, buttermilk or kefir kill the internal heat. What's more, their protein components are easy to digest and supply the body with energy without overloading it. So it's no wonder that people in India, for example, love to drink lassis (which consist of half yogurt and half mineral water). If you want to try it out right away, it's best to mix it with mango or cucumber - both have a cooling effect.
