Yawn! Do a fake yawn if you have to. That will trigger real ones. Say “ahh” as you exhale. Notice how a yawn interrupts your thoughts and feelings. This brings you into the present.
Then stretch really, really slowly for at least 10 seconds. Notice any tightness and say “relax” or just say hello to that place (being mindful — noticing without judgment). Repeat. Then, take another 20 seconds to notice and then get back to what you were doing.
Repeat every hour!
