Commuting by bike everyday has been a huge help for me, feels amazing to move your legs after a day of sitting and forces your mind to focus on something else.
Also focusing more on the now then on future outcomes and past regrets has been a very effective way to reduce stress.
Stress comes also from having a huge todo list. Get psychologically stressing things done asap (ie giving someone bad news) to keep overall anxiety down and help focus on the now.
Bike commuting sounds amazing if it wouldn’t be a source of constant enormous additional “about to get maimed or killed by a motor vehicle operator” stress for the duration. (YMMV depending on location.)
I accomplish something similar by commuting on foot, though.
By foot is also nice and less stressful, I will say bike commuting gets easier as your confidence builds but as you say it's highly location dependent.
