問題詳情

There’s some good news for people who enjoy reading. New research from the Yale School ofPublic Health suggests bookworms live longer lives. The study found that people who spent up tothree and a half hours per week reading books were 17 percent less likely to die over a 12-yearfollow up. The researchers looked at about 3,600 adults aged 50 and older, who were askedquestions about their reading habits. While a positive association was seen between longevity andreading newspapers and magazines as well, the link was stronger in people who read books.However, the study comes with a number of caveats.First, it is observational and does not prove that reading books actually causes people to livelonger. Furthermore, Dr. Murali Doraiswamy, a psychiatrist and brain health expert, points out thatthe group in the study that read books were demographically different from those who did not; theywere more likely to be female, wealthier, better educated, and overall healthier—all factors relatedto longevity. While the researchers took these factors into account in their research, "statisticscannot ever fully control for such fundamental group differences," he said.There are also dozens of other factors related to longevity that could have also differed atbaseline and were not tested for, such as leisure time, health care access, and genetics. "So theauthors are comparing apples and oranges," said Dr. Doraiswamy.Still, he notes that deep reading does have health benefits, inducing a state of relaxation called"flow" that is like meditation. Such states are known to produce changes in the body that canpromote longevity. "But we don't know if that happened here," he said.Of course, reading is also a very sedentary activity, which studies suggest can lead to an earlydeath. The researchers addressed this and said the benefits of reading may cancel out the negativeeffects of sitting, but the jury is still out. Ultimately, as Doraiswamy points out, more research isneeded. "There are many benefits to reading books such as building empathy and developing themind," he said, "but it's premature to conclude it prolongs life."
