I didn't really knew were to put this question, so feel free to move it if its not in the correct section.
So, my question is as the topic says. If you're looking for a more balanced brain on a neurochemical level. Could hard workout sessions be non-benifit for you? I do boxing, and do a lot of intervall-runnings with high intensity. I think my body feels very good about it but what about the brain?
I've heard of athlethes getting depressed when they don't exercise for a while. Could this be dopamine related or maybe connected with another substance like endorphine?
Maybe a minor increase of dopamine after a training session isn't that bad that bad? As long as its not as big and stimulating like when one uses P/M/O frequently.
