When it’s hot outside, you need to drink more water because water keeps your body cool. And probably everybody and his brother has told you that eating salt is bad for you.
But when it gets really, really hot outside, sometimes you can get very sick from the heat. And if the ambulance men come to help you, the first thing they’ll do is put a needle of something called “saline solution” into your arm. “Saline solution” is just a fancy man-word for salt water.
See, too much salt is bad for you. But when it’s very, very hot outside, you need a little bit of salt in your body to help you keep water in your body. Salt is very good at helping the body hold on to water. Why?
You’ve heard of strong worker men pouring salt on the roads when it’s icy or snowing and that’s because water loves salt. As soon as water touches salt, it goes right into the salt crystals like magic. With your body, it’s kinda the same. If your body has a good amount of salt in it, the water in your body will say, “hey, I’m not leaving this body! There’s salt in here and salt is my friend!” So the salt tells the water to stay in your body and you don’t get sick.
So if it’s very hot outside and you don’t have air conditioning, or if you’re at the water park in your cute little bikini on a very hot day, be sure to eat some saltine crackers. Drink lots of water, too! Together, salt and water will make sure you don’t get sick.
See? Simple enough for even a girl to understand.
