It certainly anecdotal, but feels like you can positively effect your gut microbiome for example by riding a bicycle. If its not the bike's biome then what is it that so satisfingly calming post ride. Would love to be enlightened. Ride a bike if you need to destress, amazing machines.

im talking about impacting your microbiome through another animal, not the short term effects from aerobic exercise or BDNF and what that feels like. this experience didnt hit quite like other typical metabolic functions.

great to hear you like BDNF. we all could use more of that.

These articles talk about subtle changes to one's microbiome by cohabiting with animals and trading microbes with them. That's a process that takes place over months if not years.

Meanwhile, you suggest that such microbial influence must be reason you feel calm right after riding your horse.

I don't think I need to further explain why it's a ridiculous claim.
