Water

Yes since I am talking about heat, there is no drink to cool you down like water.

What I like to do when I drink water is to mix it in a jar with slices of lemon or lime.
I also like to mix it with slices of orange or strawberries. You can also add in mint leaves and experiment with different ways of drinking your water.

I don't know I like to mix my water to get some more taste from it. I love water and your body loves it even more.
