Do a mindfulness exercise.
"I often teach clients is a 5-4-3-2-1 grounding exercise," says Sari Chait, PhD, a clinical psychologist and owner of the Behavioral Health and Wellness Center in Newton, MA. How it works: Start by focusing on slow, deep breaths then find five things you can see around you; four things you can touch or feel; three things you can hear; two things you can smell; and one thing you can taste.
"This mindfulness technique, like others, helps ground you where you are," she says. Doing so can not only calm the stress, but give you a clear mind to be able to problem-solve and focus on what you need to focus on to move forward, she says.
