American researchers have found out that people who work continuously without vacation live shorter than those who suffer from chronic alcoholism. The results of the respective study were published in the American Journal of Epidemiology.

A total of 749 women aged 45 to 64 participated in the study. The researchers analyzed the lifestyles of the study subjects, and collected information about their work life and bad habits. After this, the observation period of volunteers began, which lasted for about twenty years.

The analyses confirmed that the workload and lack of rest can become a serious threat to the study participants' health.

Researchers have found that the life expectancy of people who constantly overwork is shorter than the life expectancy of people suffering from alcohol addiction.

They noted that constant fatigue considerably increases the risk of cardiovascular illnesses, such as heart attack.

Moreover, three hours of overtime per day is enough to trigger this dangerous phenomenon.
