What practical step directly addresses the boundary collapse fueling the overwhelmed feeling by signaling system shutdown?

Creating a hard 'Transition Ritual' at the end of the workday, like a walk or meditation.

The feeling of being perpetually overwhelmed stems in part from the collapse of boundaries between professional stress and personal life, keeping the brain in a constant state of alertness. A highly effective, proactive step recommended to combat this is establishing a hard Transition Ritual at the workday's conclusion. This ritual is an intentional, explicit action—such as a brisk walk around the block or a short guided meditation—that serves as an artificial buffer zone. Its entire purpose is to signal clearly and decisively to the brain that the 'on' switch associated with work demands has been flipped 'off,' thereby helping to isolate the stress generated in the work environment from the restorative home environment.
