Why Is Staying Connected to Nature Important for Us?

I've been wondering lately why spending time outdoors feels so calming and energizing. There seems to be something deeply satisfying about walking in a forest or just sitting in a park. Could it be that humans have a natural bond with the environment that we tend to forget in modern life? I'm curious to know what benefits people have noticed from staying in close contact with nature. What is it that makes this connection so important for our overall well-being?
