In his book The Stress of Life, Hans Selye wrote that many different environmental stressors, such as heat
or cold, pain or danger, disrupt the body’s equilibrium and lead to a three-phase physiological reaction.

A person living in a country that is at war is faced with constant danger and threat of death as well as poor living conditions, decreased availability of healthy food and clean water.  Thus, they are exposed to multiple physical and psychological stressors on a daily basis.
The alarm phase of the general adaptation syndrome might occur when a bomb goes off nearby or they hear nearby gunfire.  They would experience sympathetic nervous system arousal, including things like increased blood pressure, tense muscles, and increased heart rate.
As they continue to be exposed to such stressors on a daily basis, they would enter the resistance phase.  The body becomes more vulnerable to other stressors, they become more irritable and annoyed by minor things, and their health may deteriorate.
Eventually they reach the exhaustion phase when the persistent stress has depleted the body of energy.  They may become ill, developing chronic hypertension, headaches, digestive disorders, etc.  They may die.
