Research and population surveys have shown that persons under stress , particularly chronic stress, tend to exhibit more unhealthy behaviors than less-stressed persons. Stressed people drink more alcohol, smoke more, and eat less nutritious foods than non-stressed individuals.

Many people report drinking alcohol in response to various types of stress, and the amount of drinking in response to stress is related to the severity of the life stressors and the individuals' lack of social support networks.

Alcoholism is a complex medical condition that is believed to be caused by a number of both hereditary and environmental factors. While stress is not considered to be a cause of alcoholism, stressful experiences may lead to  relapse of the disease in those who already suffer from alcoholism.

that alcohol actually increases the stress response by stimulating production of the same hormones the body produces when under stress.
