 So there's a couple of things with that. One is hydration. So a lot of people in the summer actually get joint and muscle pain because as you mentioned, it's really hot and they're outside working or doing sports, but they don't adequately hydrate themselves. Now with hydration, I'm not just talking about water because water by itself can actually dilute the minerals that you have. And this becomes really important for muscle function also because your muscles actually start cramping when your minerals go down in concentration.
