I'm sure that's a thing for some people. And there's research to back that up IIRC. Even seemingly silly things like the smell of a wet forest being beneficial.

One aspect which stood out for me is 'awareness'. I find it deeply fascinating how many people, as I used to be one, can just stroll through everyday locations without even knowing the names of the most common plants let alone think about their connection to the surroundings. Once I started to realize how unaware I was of this I started forzing myself to be more aware and it's fascinating how much there can be going on in like even 1 square meter of nature. And of which I only know a fraction.

And for me this is really meditative - even though it's somewhat counterintuitive. Meditation is usually about clearing the mind, but for me being in nature and filling my mind with thoughts about the whole interconnection of individuals in ecosystems can bring peace and relaxation. Well, as long as I do not think about how we're collectively destroying a lot of it.
