Certain low-impact exercises like meditation, tai chi, and yoga can have an incredible calming effect on the mind and body. Belly Breathing is an exercise that can help seniors breathe more effectively to get the maximum calming benefit. Here’s how: Breathe in through your nose. Pay attention to how your belly fills up with air. Breathe out through your mouth at least two to three times as long as you inhale. Be sure to relax your neck and shoulders as you retrain your diaphragm to take on the work of helping to fill and empty your lungs.
