A  new mobile application program for smart phone users released by the Department of Defense can help reduce the stress associated with post-traumatic stress disorder (PTSD) and traumatic brain injury. 
 
Breathe2Relax (link) , part of a growing collection of mobile applications developed by the National Center for Telehealth and Technology (T2), is available for iPhone® users now. An Android version will be available by the end of July.  The app teaches and encourages diaphragmatic breathing exercises. These deep-breathing exercises can help people refocus and relax when anxiety spikes easing tension by stimulating the “relaxation response.”
