Stress is a common source of anxiety for Americans. The U.S. Department of Defense has created a portable stress management tool, which consumers can use to practice breathing exercises for relaxation. Breathe2Relax helps with mood stabilization, anger control, and anxiety management. The app, available for iPhone, iPad, and Android, can be used as a standalone stress reduction aid or in tandem with clinical care. It also includes a reference guide on the effects of stress on the body and instructions for dealing with stress.
