 Help Heal Veterans helps veterans with PTSD and stress for military service and isolation during the coronavirus. For the next minute, let's take a minute to relieve stress together. We'll do the 4-7-8 breathing exercise. First, sit with your back straight. Second, place your tongue against the roof of your mouth behind your front teeth. Now, exhale through your mouth and around your tongue. If this seems awkward, shape your lips like you're whistling. Close your mouth and inhale through your nose for the count of four.
