The statistics about veteran suicide have changed little over the years, hovering most consistently at twenty suicides a day. Most emphasis has been placed on increasing the availability of mental health services for returning soldiers, yet theaters of war present a myriad of factors affecting human health from exposures to toxic elements, extreme environments, and a lack of proper nutrition, not to mention the emotional experiences that all together create a cascade of individualized chemical messenger responses to unrelenting stressors. The War Within informs soldiers, veterans, family members, and caretakers how to first understand what happens to the body under such stressors in theaters of war and how this affects the brain. Once one understands what has happened to the physical body, then appropriate decisions and practices can be undertaken to restore the physical reserves of our warriors, ultimately reversing the heartbreaking suicidal trend that we recognize is currently taking place. The War Within presents a five-part, well-researched program that can serve as a vital complement to the important mental health programs presently being provided for our soldiers and veterans. This program is easy to implement into daily routines, and it enables restoration of optimal brain function, thus reducing the incidence of depression, hopelessness, fatigue, and suicidal ideation.
