Alcohol dulls the senses. Movies dull the senses. Scrolling Twitter dulls the senses. These things relieve excess brain action, distracting us from the honesty of focus.

“To you, clerk, literary man, sedentary person, man of fortune, idler, the same advice. Up!” — Walt Whitman
That is to say, go for a walk. Take acknowledgment of the senses. Whatever exercises the body, relieves the mind.
