Action line items and link with feelings.

Hello. Are they any situations where action line items impact feelings? For example, a walk in the fresh air and in nature seems to make me feel happier and more alive. I appreciate it might just be my thoughts about it, but could I really generate the same thoughts sitting at home on my sofa? Also perhaps there’s a element there of fresh air creating a physical response in my body? I’m asking because going for a walk in nature to make me feel better doesn’t sit well in the model. Thanks!
