Stress hormones on the battlefield

Some people cope with stress much better than others. There can be few situations more stressful than military conflict and researchers at Yale University looked at stress hormones among soldiers undergoing their survival training. They found that those soldiers who coped with their training best had lower levels of the stress hormone cortisol and produced more of a substance called neuropeptide Y, a chemical that dampened the body's stress response.
