Cabin fever is a feeling of being stuck inside for too long without any way of getting out. It's like when you have been inside your house for a long time and you start to feel bored and restless.
Imagine you are playing with your toys in your room and it starts to rain outside. Your mom tells you that you can't go outside because it's not safe to play in the rain. You keep playing with your toys, but after a while, you start to feel like you want to do something else.
You might start to feel like you want to go outside and see your friends or go to the park. But since you can't, you start to feel frustrated and a little bit cranky.
That's kind of what cabin fever is like, but for grown-ups. When adults are stuck inside for a long time, without being able to go outside or do things they normally like to do, they can start to feel restless and anxious.
Cabin fever can happen to anyone, but it's more common during periods of isolation or bad weather. It's important to find ways to stay connected with others and to do things that make you feel good, even if you can't leave your house. That way, you can avoid feeling cabin fever and stay happy and healthy.
