Loneliness affects health As we all know, loneliness has a negative effect on people's mental health. A study conducted by the University of Chicago and the University of California in the United States shows that loneliness can also damage the health of human cells. When people are lonely or show a sense of loneliness, the content of inflammatory molecules in their blood is higher. Therefore, loneliness may have an impact on health. Because these molecules will affect the long-term operation of cells and increase the risk of chronic diseases and premature death. Loneliness can change the expression of some genes, especially those responsible for the production of white blood cells. These cells play an important role in the human immune system, so their changes will destroy the immune system, so the human body can not resist the invasion of bacteria and viruses. Therefore, lonely people are more likely to be infected, either a simple cold or some more serious chronic diseases. 本文来源：https://www.wddqw.com/doc/c380a576bd1e650e52ea551810a6f524ccbfcbe8.html
