Reading a good book might do more than help you unwind. Researchers at Yale University found that adults who regularly read books had a 20 percent lower risk of death during a 12-year follow-up compared with people who didn’t read books.
The finding comes from a 2016 study published in Social Science & Medicine that examined 3,635 Americans over age 50. The research has attracted renewed attention in October 2026, raising an intriguing question: Could something as simple as reading help support a longer life?

Why Books Had an Advantage Over Newspapers
Researchers compared book readers with people who preferred newspapers and magazines. Both activities involved reading, but books showed a stronger association with survival.
The researchers also accounted for age, education, wealth, existing health conditions, and other factors that might influence survival.
Their findings suggest that the type of material people read could matter, not merely the time spent reading.

The Brain May Explain the Unexpected Connection
One possible explanation involves cognitive engagement.
Books often demand sustained attention, comprehension, and the ability to connect ideas across chapters. Researchers examined whether these mental processes might help explain the relationship between reading and survival.
Their analysis identified cognitive performance as a statistical mediator of the association.
However, the study was observational. It cannot establish that reading directly prevents disease or extends life.
That distinction matters because people who read regularly may differ from nonreaders in ways researchers cannot fully measure.

How Much Reading Could Make a Difference?
The researchers divided participants into three groups: nonreaders, people reading up to 3.49 hours weekly, and those reading at least 3.5 hours.
Both reading groups demonstrated a survival advantage compared with nonreaders after statistical adjustments.
For perspective, 3.5 hours weekly works out to approximately 30 minutes daily.
That doesn’t establish a medically recommended reading prescription, but it offers a manageable starting point.
The Men’s Journal takeaway: Reading shouldn’t replace exercise, adequate sleep, or preventive healthcare. But setting aside half an hour for a book is an accessible way to stay mentally engaged—and potentially support healthier aging.
