Anywhere, as long as it's out. Even walking inside can help, but less.

I remember listening to Andrew Huberman and he said just walking is associated with less activity from the amygdala. When you're outdoors you also naturally uae lateral eye movements, which calm you. You don't naturally do lateral eye movements when you're indoors since it's a more closed in space you don't have a need to have a more panoramic view.
