German scientists at the University of Mainz conducted a representative study that helped to determine what kinds of people are more likely to suffer from insomnia. As it turned out, one reason is social status.
According to the researchers, it is understandable that people who have sleep problems, experience more mental and physical stress. Conversely, mental stress and discomfort in the body, such as pain in the heart and chest, upset stomach, and shortness of breath, accompanied by a lower quality night’s rest. To understand the issue a group of scientists interviewed 2515 people. The results showed that women, the elderly, the poor or unemployed persons with low education level, single individuals of both sexes are especially vulnerable to insomnia.
As noted by scholars, the reason for the study was the reports of medical insurance, according to which sleep disturbances are an underappreciated cause of high disease burden in the working environment and road accidents.
