Humidity

Humidity is like the amount of water in the air around us. Imagine you're playing outside on a hot summer day, and you start sweating! When you sweat, your sweat makes your skin wet. That's because your sweat is made up of mostly water. When the air around you is hot and humid, that means there is already a lot of water in the air. And since the air can't hold any more water, your sweat can't evaporate very quickly, which makes you feel even hotter and stickier than if the air was drier.

Now imagine you're in the bathroom after someone has taken a steamy shower. The mirror gets all foggy because the warm, moist air from the shower doesn't have anywhere to go, and it ends up sticking to the cool surface of the mirror. That's kind of like what happens when the air is really humid outside - the water in the air just sort of hangs around, and can make things like windows or floors feel damp even if they're not wet.

Humidity can make a big difference in how comfortable we feel, especially when it's hot outside. When it's really humid, it can make us feel like we're breathing in air that's as thick as soup, because all that water is taking up space in the air around us. So it's important to keep an eye on the humidity levels and try to stay cool and hydrated on those extra-humid days!
