Yoga, if I do it regularly, is especially helpful all around. In the moment, if I'm in a social situation, I'll simply put both feet on the floor/ground, place my hands palm down on my thighs, breath evenly, and feel the sensations that my body is experiencing - perhaps it will be noticing the small cloth fibers in the carpet, the disproportionate weight of my palms (fore palms are heavier than finger tips), or the notice all the tiny bits of tension in my facial muscles. One of my favorite things to do, when I'm able, is to lay on a freshly cut grass lawn, feel all the sensations in my body that I'm able to, and just look and listen to what's around me.
