"Exercise is one of the most efficient ways that our body biologically processes stress out of it," Dr. Wang explained. Something Moffa always says is "emotion is better in motion," which applies to anxiety and grief because, she noted, they get "stuck" in your body and cause tightness in your chest, shortness of breath, and other physical symptoms. Pick your movement of choice — she suggested even just dancing out your emotions to music. Try yoga or head out for a run (Dr. Wang's go-to) to let what you're feeling move through you.
