There are many reasons for premature death. Smoking, drinking too much, eating too much salt, hypertension and other factors have been known for a long time and have attracted enough attention. However, the Medical Journal of the United States published five causes of premature death that are easy to be ignored, which should be paid more attention to.
1. I love watching TV watching TV will lead to a sedentary lifestyle, which will shorten your life. Scientists from the school of public health of the University of Nevada in the United States conducted an average follow-up survey of 13284 graduates for 8.2 years. They found that compared with the participants who watched TV for 1 hour or less every day, the participants who watched TV for at least 3 hours a day had a twofold increase in the risk of early death.
2. I feel lonely a new study by the University of Chicago involving more than 2000 participants over the age of 50, published at the Chicago annual meeting of the American Association for the advancement of science, found that extreme loneliness increased the risk of premature death. The elderly who feel lonely are more difficult to relieve pressure and restore a positive attitude towards life. Loneliness can also lead to hypertension, increase the level of stress hormone cortisol, and interfere with normal sleep. Dr. John kajoub, the leader of the new research, said that in general, the risk of early death of lonely elderly people would increase by 14%.
3. Early retirement although workaholics are under great pressure, the risk of premature retirement and early death is not small. Researchers from the University of Zurich in Switzerland conducted an in-depth study on the correlation between death risk and retirement time of manual workers. The results showed that the risk of death before the age of 67 was greatly increased for men who retired prematurely. The risk of premature death increases by 13.4% for every year of early retirement. The decrease of physical exercise after retirement and the loss of work goals are the two main reasons.
4. Air pollution indoor and outdoor air pollution is another common cause of premature death that is easy to be ignored. According to the World Health Organization (who), air pollution is the largest environmental health risk in the world. Excessive exposure to air pollution will increase the risk of stroke, ischemic heart disease, acute respiratory infection, chronic obstructive pulmonary disease (COPD) and some cancers. According to who data, 7 million deaths (accounting for 1 / 8 of the deaths) in 2012 were related to air pollution.
5. Brush your teeth infrequently a 24-year study involving 1390 participants completed by Swedish scientists found that unsanitary mouth can increase the risk of early death from cancer. At the end of the study, 58 subjects died, of which 35 died of cancer. The study found that the plaque index of the dead subjects was higher than that of the surviving subjects. Researchers believe that dental plaque is closely related to a variety of internal infections, and long-term oral hygiene will also increase the risk of cancer.
