I have a ritual that I do daily, almost without thinking about it anymore. As I am walking to or from the time clock at work, I take a deep breath (sometimes closing my eyes, sometimes not) and work on trying to relax and release some of the stress that I am physically holding in my body. I try to relax my overly tight muscles, correct my posture so that my body is more open, and moves more freely, and let go of all the things that are bearing down on me after a long shift.
I do this other times too, but this is the most regular. It has become an ingrained habit with me, to sort of shed the stress of the mundane world as I go into work, and the stress of my work life as I head home, so that I enter each space with a clear head able to give my best. A quick check in throughout your day, perhaps as you pass the threshhold of your home, entering or exiting your car while running errands, or before you lie down to bed at night can be a good way to judge and mitigate the stress and tension that we each hold onto in our physical and mental selves.
