Stress may be considered as any physical, chemical, or emotional factor that causes bodily or mental unrest and that may be a factor in causing disease. Physical and chemical factors that can cause stress include trauma, infections, toxins, illnesses, and injuries of any sort.
Stress: In a medical or biological context stress is a physical, mental, or emotional factor that causes bodily or mental tension. Stresses can be external (from the environment, psychological, or social situations) or internal (illness, or from a medical procedure). Stress can initiate the fight or flight response, a complex reaction of neurologic and endocrinologic systems. Catecholamine hormones, such as adrenaline or noradrenaline, facilitate immediate physical reactions associated with a preparation for violent muscular action.
