Picking up a book for fun can do more than just pass the time. A new editorial summary published in Psychological Medicine indicates that reading for pleasure is linked to better cognitive performance, differences in brain structure, reduced stress and a reduced risk of dementia later in life. Based on evidence, the authors argue that recreational reading and participation in book clubs could be accessible, low-cost tools to support mental well-being and protect the aging brain, including among people from low-income or less-educated backgrounds.
Reading for pleasure, often called voluntary or recreational reading, is the act of reading material willingly in anticipation of the satisfaction the activity brings. This encompasses not only print novels and non-fiction books, but also digital formats, magazines, comics and graphic novels. In their editorial, the authors examine this daily pastime through the lens of preventive psychiatry, an approach aimed at reducing the risks of mental health disorders before they take hold.
Data from the World Health Organization indicates that more than a billion people worldwide live with a mental health problem and approximately one in seven adolescents aged 10 to 19 suffer from 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 closely studying changeable lifestyle habits that build psychological resilience, which helps people resist stress, as well as cognitive reserve. Cognitive reserve is the brain’s ability to continue functioning well despite aging or damage. It is thought to accumulate through mentally stimulating experiences and to act as a buffer against cognitive decline and dementia.
Because reading is mentally stimulating and can be shared with others, the authors suggest that it can simultaneously strengthen cognitive reserve and alleviate social isolation. The authors of a 2020 study on socioeconomic inequality noted that growing up in low-income households is linked to measurable differences in how brain circuits supporting the development of language, memory and emotion regulation. Faced with these disparities, the authors of the editorial emphasize the need to identify inexpensive habits that can help offset environmental disadvantages.
To assess how recreational reading might play this protective role from childhood to old age, Barbara J. Sahakian of the University of Cambridge and colleagues brought together findings from charity literacy surveys, long-term cohort studies, and brain imaging research.
The authors first looked at data from a UK National Literacy Trust survey of young people’s reading habits. Data from the 2024 and 2025 annual literacy surveys indicated that recreational reading among children and adolescents continued to decline and may have reached its lowest levels since tracking began, particularly among boys aged 11 to 16. By 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 their peers who did (15.8 percent).
Despite this downward trend, data from the 2024 survey demonstrated a link between enjoyment of reading and scores on the STAR Reading assessment. Children and adolescents who said they liked reading (1,211 participants) obtained an average score of 109.13, compared to an average of 102.65 among the 2,593 students who did not like 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 suggests ways to re-engage reluctant young readers. In this survey, 38.1 percent of young people felt motivated by material related to a favorite movie or TV series, 37.1 percent were motivated by material related to their interests or hobbies, and 26.6 percent enjoyed choosing their own reading material.
The synthesis also examined longitudinal research on the relationship between reading ability and 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 of 554 elementary school students with an average age of 6.5 years, average and high reading scores predicted faster growth in math skills over time, particularly among students whose math scores were initially below average.
To examine the link between recreational reading and adults’ emotional well-being, the authors cited several self-report surveys conducted by literacy organizations. In a 2015 survey of 4,164 adults, 64% of those who read at least 30 minutes a week reported understanding others’ feelings better, compared to 48% 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 of relieving stress.
In a 2022 survey of around 2,000 people by reading charity The Reader, 74% of respondents said reading was beneficial for their mental health, and 41% said it helped them feel more connected to others. Among young adults ages 18 to 34 surveyed in this survey, 59% felt reading increased their connection with others and 56% said it helped them feel less alone during pandemic lockdowns.
Shared reading in book clubs also appears to provide social benefits to different age groups. A qualitative study of 168 tenth graders participating in book clubs found that 61.2 percent reported having a better understanding of others’ perspectives, 42.9 percent felt an increased sense of connection, and 14.3 percent reported feeling less alone. Similarly, a 2025 systematic review of 11 studies indicated that group reading activities among older adults reduced depressive symptoms and alleviated social isolation, although the review 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, providing a stronger protective effect than monthly social activities.
The editorial also builds on an earlier analysis co-authored by Sahakian and Langley of the Adolescent Brain Cognitive Development (ABCD) cohort, a large U.S. study that followed 10,243 adolescents ages 9 to 11 through 11 to 13 years old. About half of the sample (51.8 percent) had begun reading for pleasure in childhood, recording 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, as well as fewer symptoms of depression, stress and behavioral problems. They also spent less daily time in front of a screen and slept longer than their peers who did not read early.
Brain scans of these early readers showed larger tissue volumes and surface areas in several regions involved in language processing, attention and emotion regulation. These associations held even after researchers statistically controlled for age, biological sex, body mass index, puberty status, race and ethnicity, family structure, parental education and household income. This analysis, first published in 2023, also found that cognitive benefits peaked at around 12 hours of reading per week.
Among older adults, long-term cohort studies reviewed by the authors linked reading to a lower risk of cognitive decline. A study of 5,437 cognitively healthy adults aged 55 and older over five years found that frequent participation in mental activities like reading and playing chess was linked to a lower likelihood of developing cognitive impairment.
Another study of 801 adults aged 65 and older for an average of 4.5 years found that each one-point increase in a measure of cognitively stimulating activities, which included reading books, magazines and newspapers, was associated with a 33% lower risk of developing Alzheimer’s disease. A separate study of 469 adults aged 75 and over 5.1 years associated reading itself with a 35% lower risk of overall dementia.
Reading also appears to compensate for 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 problems with thinking or memory, and 36.82% of whom read regularly, readers outperformed nonreaders on all cognitive assessments, even among those with less formal education. However, brain MRIs in this study 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 associated with a lower risk of cognitive decline at ages 6, 10, and 14 across all levels of formal education. Together, these studies suggest that regular reading habits later in life could help compensate for limited early schooling.
To explore how reading might physically shape the brain, the authors looked at neuroimaging studies of both gray matter, which contains bodies of neural cells that process information, and white matter, the bundled nerve fibers that connect different regions of the brain. In children aged 8 to 13, better 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…
