Reading for pleasure is linked to better brain health across the lifespan

Picking up a book for fun might do far more than simply pass the time. A new editorial synthesis published in Psychological Medicine indicates that reading for pleasure is tied to better cognitive performance, differences in brain structure, lower stress, and a reduced risk of dementia in later life. Based on the evidence, the authors argue that recreational reading and participating in book clubs could serve as accessible, low-cost tools to support mental well-being and protect the aging brain, including among people from lower-income or less-educated backgrounds.

Reading for pleasure, often called voluntary or recreational reading, is the act of reading materials of one’s own free will in anticipation of the satisfaction the activity brings. This encompasses not only printed novels and nonfiction books, but also digital formats, magazines, comic books, and graphic novels. In their editorial, the authors examine this everyday pastime through the lens of preventive psychiatry, an approach aimed at lowering the risk of mental health disorders before they take hold.

World Health Organization data indicates that more than one billion people globally live with a mental health condition, and roughly one in seven adolescents aged 10 to 19 experiences a mental disorder. In this age group, anxiety, depression, and behavioral disorders are among the leading causes of illness and disability.

In response to these numbers, researchers are looking closely at modifiable lifestyle habits that build psychological resilience, which helps people weather stress, and cognitive reserve. Cognitive reserve is the brain’s capacity to keep functioning well despite aging or damage, which is thought to build up through mentally stimulating experiences and act as a buffer against cognitive decline and dementia.

Because reading is mentally stimulating and can be shared with others, the authors suggest it may simultaneously strengthen cognitive reserve and ease social isolation. The authors of a 2020 review on socioeconomic inequality noted that growing up in lower-income households is linked to measurable differences in how brain circuits supporting language, memory, and emotion regulation develop. In light of these disparities, the editorial’s authors emphasize the need to identify low-cost habits that can help offset environmental disadvantages.

To evaluate how recreational reading might serve this protective role from childhood through old age, Barbara J. Sahakian of the University of Cambridge and her colleagues brought together findings from literacy charity surveys, long-term cohort studies, and brain imaging research.

The authors first examined survey data from the United Kingdom’s National Literacy Trust tracking reading habits among young people. Data from the 2024 and 2025 Annual Literacy Surveys indicated that recreational reading among children and teenagers has continued to fall and may have reached its lowest levels since tracking began, particularly among boys aged 11 to 16. In 2025, the gap between girls and boys who read daily widened to 6.2 percentage points, and children who did not receive free school meals, a standard UK indicator of low household income, were more likely to read daily (19.4 percent) than peers who did receive them (15.8 percent).

Despite this downward trend, the 2024 survey data pointed to a link between reading enjoyment and scores on the STAR Reading assessment. Children and adolescents who reported enjoying reading (1,211 participants) achieved an average score of 109.13, compared to an average of 102.65 among the 2,593 students who did not enjoy reading. Similarly, the 789 students who read daily scored an average of 109.49, compared to 103.35 among the 3,026 non-daily readers.

The 2025 survey also suggested ways to reengage reluctant young readers. In that survey, 38.1 percent of youth felt motivated by material tied to a favorite film or television series, 37.1 percent were motivated by material matching their interests or hobbies, and 26.6 percent valued choosing their own reading material.

The synthesis also examined longitudinal research on how reading ability relates to mathematical development. Reading and math share several underlying mental processes, including phonological awareness, which is the ability to recognize and manipulate the spoken parts of words, and executive functions, the mental skills used to plan, focus attention, and juggle multiple tasks. In a study following 554 elementary school children from an average starting age of 6.5 years, average and high reading performance predicted faster growth in math skills over time, especially among students who initially performed below average in math.

To examine how recreational reading relates to adult emotional well-being, the authors cited several self-report surveys conducted by literacy organizations. In a 2015 survey of 4,164 adults, 64 percent of those who read for at least 30 minutes a week reported a better understanding of other people’s feelings, compared to 48 percent of non-readers. Among readers, 17 percent said they remained calm during disagreements, compared to 5 percent of non-readers, and 38 percent identified books as their preferred method for stress relief.

In a 2022 survey of roughly 2,000 people conducted by the reading charity The Reader, 74 percent of respondents reported that reading benefited their mental health, and 41 percent said it helped them feel more connected to other people. Among young adults aged 18 to 34 in that poll, 59 percent felt reading increased their connection to others and 56 percent said it helped them feel less alone during pandemic lockdowns.

Shared reading in book clubs also appeared to offer social benefits across different age groups. A qualitative study of 168 tenth-grade students in book clubs found that 61.2 percent reported a greater understanding of other people’s perspectives, 42.9 percent felt an increased sense of connection, and 14.3 percent reported feeling less lonely. Similarly, a 2025 systematic review of 11 studies indicated that group reading activities among older adults reduced depressive symptoms and eased social isolation, though the review’s authors noted that study methods varied widely.

These findings are consistent with a recent study of older adults, which found that maintaining a daily reading routine was associated with lower loneliness scores among people with small social networks, offering a stronger protective effect than monthly social activities.

The editorial also draws on an earlier analysis co-authored by Sahakian and Langley of the Adolescent Brain Cognitive Development (ABCD) cohort, a large U.S. study that tracked 10,243 adolescents from ages 9 to 11 through ages 11 to 13. Roughly half of the sample (51.8 percent) had started reading for pleasure early in childhood, logging between 3 and 10 years of recreational reading, while the remaining 48.2 percent had little or no early reading experience, ranging from 0 to 2.5 years.

Adolescents in the early-reading group showed better performance on tests of working memory, attention, and verbal learning, alongside fewer symptoms of depression, stress, and behavioral problems. They also logged less daily screen time and slept longer than peers who did not read early.

Brain scans of these early readers showed larger tissue volumes and surface areas across several regions involved in language processing, attention, and emotion regulation. These associations held even after the researchers statistically controlled for age, biological sex, body mass index, puberty status, race and ethnicity, family structure, parental education, and household income. That analysis, first published in 2023, also found that cognitive benefits peaked at around 12 hours of reading per week.

In older adulthood, long-term cohort studies reviewed by the authors linked reading to a lower risk of cognitive decline. One study tracking 5,437 cognitively healthy adults aged 55 and older over five years found that frequent engagement in mental activities like reading and playing chess was tied to a lower likelihood of developing cognitive impairment.

Another study following 801 adults aged 65 and older for an average of 4.5 years reported that each one-point increase on a measure of cognitively stimulating activities, which included reading books, magazines, and newspapers, was associated with a 33 percent lower risk of developing Alzheimer’s disease. A separate study of 469 adults aged 75 and older over 5.1 years linked reading itself to a 35 percent lower risk of overall dementia.

Reading also appeared to offset the cognitive disadvantages often seen in older adults with fewer years of formal schooling. In a cross-sectional study of 459 older adults who reported no thinking or memory problems, where 36.82 percent read regularly, readers outperformed non-readers across all cognitive assessments, even among those with less formal education. Brain MRI scans in that study, however, showed no structural differences between the two groups.

Similarly, in a 14-year study that followed 1,962 adults over age 64 across four assessment waves, reading at least once a week was linked to a lower risk of cognitive decline at the 6-, 10-, and 14-year marks across all levels of formal education. Together, those studies suggest that regular reading habits in later life may help compensate for limited early schooling.

To explore how reading might physically shape the brain, the authors reviewed neuroimaging studies of both gray matter, which contains neural cell bodies that process information, and white matter, the bundled nerve fibers that connect different brain regions. In children aged 8 to 13, stronger performance on word identification tests correlated with better organization of white matter pathways, particularly in the left hemisphere, which is heavily involved in language. Researchers measured this pathway organization using a specialized MRI technique called diffusion tensor imaging.

In a separate line of research, one small study of 11 children aged 7 to 11 with dyslexia, a learning difference that makes reading difficult, found that after an eight-week training program focusing on mental imagery and word tracing, reading skills improved and gray matter volume increased in brain areas involved in memory and language, including the hippocampus. Some of the reading gains were still present eight weeks later.

Similar structural patterns appeared in adult brain imaging studies. Among young adults aged 18 to 25, greater exposure to print, measured by familiarity with author names and book titles, was linked to a thicker cerebral cortex, the brain’s outer layer, in areas that process language, independent of the person’s reading skill. Intensive literacy training in adults who previously could not read or write well enough to manage everyday tasks was also associated with gray matter growth in language-related brain regions.

In a study using functional MRI, which tracks brain activity by measuring changes in blood flow, 26 young adults aged 19 to 26 read literary passages inside a scanner. The texts activated the default mode network, a connected set of brain regions active when people daydream, recall memories, or imagine another person’s thoughts and feelings, a skill known as theory of mind. Vivid descriptive scenes and socially rich passages engaged distinct parts of this network, and activity in the social-processing portion statistically accounted for part of the link between frequent fiction reading and stronger performance on tests of social understanding.

“The most important takeaway is that reading for pleasure is associated with a range of healthier outcomes, including better mental and social health as well as better cognitive function,” Angelina R. Sutin, a professor in the Department of Behavioral Sciences and Social Medicine at the Florida State University College of Medicine who was not involved in the research, told PsyPost. “This summary of the research on the health benefits of reading largely supports conclusions from existing work. This summary does do a nice job of organizing this literature to demonstrate both the broad reach of the benefits of reading and how reading benefits health across all stages of the lifespan.”

As with all research, there are some caveats to consider when interpreting the findings compiled in this paper. The article is an editorial rather than a systematic review, meaning the authors selected which studies to highlight rather than following a formal protocol to gather all available evidence. Much of the survey data on reading habits, stress, and empathy comes from reports published by literacy charities rather than peer-reviewed journals, and self-selected survey respondents may not reflect the general public. In addition, the school test data cannot rule out reverse causation: children who are already strong readers may simply find reading more enjoyable, rather than reading enjoyment driving higher test scores.

More broadly, most of the human studies on lifelong reading are observational, meaning they track people’s existing habits rather than assigning them to read, so they cannot prove that reading directly causes brain changes or prevents dementia. “As much as I appreciate the results and want to support the benefits of reading, most of the studies reviewed in this piece were observational,” Sutin explained. “The longitudinal studies are helpful to test whether reading can predict outcomes in the future. Still, there is the possibility that individuals who are healthier, and maintain their health over time, are also the kinds of people who read.”

“General readers might overinterpret the findings to mean that they will have better health if they start reading for pleasure,” Sutin added. “I think the real value of this summary is laying the foundation for exciting research that should come next. The authors nicely argue and present foundational evidence for the importance of reading for better mental, social, and cognitive health. The next step is to experimentally test whether individuals randomly assigned to read for pleasure improve in these aspects of health more than individuals randomly assigned to an active control.”

An active control is a comparison group that spends the same amount of time on a different activity, such as doing puzzles, rather than doing nothing. The editorial’s authors similarly note that further experimental research is needed to establish causal pathways and map out the exact brain mechanisms behind reading’s benefits. They also hope to investigate whether brain plasticity, the brain’s ability to change in response to experience, can support better brain structure, cognitive function, and well-being among adults who take up reading for pleasure later in life. The University of Cambridge team plans to pursue these questions in a collaboration with the UK literary charity The Queen’s Reading Room, and the paper discloses that co-author Vicki Perrin is the charity’s chief executive officer.
