Gentle, slow, walking – best done in nature – sends a signal to the brain and by slowing down the body we slow down the rushing mind. It can put things in perspective and prevent us from living all the time in our heads:
In my room, the world is beyond my understanding;
But when I walk I see that it consists of three or four
hills and a cloud.
Wallace Stevens, Of the Surface of Things

Daily “sit-ins” on our back porch among swaying birches and evergreens…..watching hummingbirds, jays, and a lovely dove couple makes life really simple after a day of sunshine depletion at work.
