What do American scientists say about the benefits of reading books?

Scientists from Yale University (Yale University School of Public Health) stated that reading is not only a fun activity and a means of increasing knowledge. As you say, reading books has great benefits for human health.

Experts conducted research and determined that the book prolongs human life. People who read more than 3.5 hours a week have a 23% lower risk of early death than those who never read.

In addition, scientists have clarified the 5 most important reasons for the importance of reading books.

First, reading relieves stress, which is the cause of 60% of all diseases, as well as stroke and cardiovascular disease. It goes without saying that it is not in our hands to protect our lives from stress. However, reading books reduces the negative impact of stress on the human body. Second, reading improves the brain's cognitive function and memory. Third, reading improves the quality of sleep. That is, it eases the transition between sleepiness and insomnia, which cannot be said about smartphones. Fourth, reading improves social skills. Well-educated people can understand and feel what other people are thinking. The last and most important reason is that reading books increases the intellectual level of everyone.
