I’ve seen this mentioned a few times and it’s very interesting. Healthy habits of thought? I’m not sure quite how to fully define such a thing. I’ve been trying to think of a collection of examples to post about though.
One is something I want to call “therapeutic social isolation” which involves spending time processing things by myself. Processing by yourself and processing around other people are going to feel different and that’s likely to be a good difference to feel. Maybe we have an instinct for such social isolation if we get “overloaded”.
Another thing which is like a version of the first is if I feel particularly intense about a piece of writing, even a text, I do a draft and come back later. Later can be an hour, the next morning, a couple of days… I can’t say how long it takes to move an experience from short to long term memory but a night of sleep can be useful in seeing if you still feel the same.
I’m sure there are many things that can be included in something like mental hygiene. I’m not sure what it looks like as a fleshed out concept but that’s a start.
