Sauna

Okay, so you know when you get really hot, and your face gets all red and sweaty? Well, a sauna is like that except on purpose! It's a special room that's really, really hot, like way hotter than outside on a sunny day.

You sit or lie down in the sauna and just relax. It may feel uncomfortable at first, but then you start to feel really good, like you're baking in the warm glow of a hug. Some people even like to throw water on the special rocks in the sauna to make steam, which makes it feel even hotter.

But be careful, you don't want to stay in there too long or you might feel sick. So it's important to listen to your body and get out when you've had enough. After you get out, you'll feel all warm and fuzzy and relaxed.

So that's what a sauna is, a hot and cozy room that helps you unwind and feel good.
