From Boosting Mental Health to Reducing Dementia Risk, Here's Why Reading Is Extremely Good for You, According to Science

Reading has long been considered beneficial, often encouraged by those who believe insufficient engagement with the activity. Scientists have now collated research on the advantages of recreational reading, particularly for children, adolescents, and older individuals. By examining various studies using longitudinal, neuroimaging, and behavioral methods, researchers discovered connections between reading and enhanced brain health, overall well-being, and a decreased risk of cognitive decline.

The findings were published in the September 15 issue of Psychological Medicine. Christelle Langley, a co-author and cognitive neuroscientist at the University of Cambridge, explains that reading is a simple and accessible means of supporting cognitive performance, brain health, mental health, and general well-being throughout one's life.

One study involving over ten thousand participants, published in 2023, revealed that early readers experienced several benefits compared to non-readers. These advantages included lower rates of mental health issues, higher academic achievement, improved attention, memory, and executive functioning, as well as healthier habits such as reduced screen time and increased sleep.

Early readers even demonstrated enhanced cognitive performance in adulthood. Compared to passive screen time like watching TV or movies, reading requires active construction of the storyline in one's mind, a process known as "imaginative work." Psychologists note that this mental engagement may contribute to the observed benefits.

Past research has also established links between reading and improved literacy skills among young people, as well as connections between reading and mathematical achievement. In adults, a survey indicated that regular reading promotes empathy, tolerance for diverse viewpoints, and stress reduction. Surprisingly, just six minutes of reading can lower stress levels by nearly 70 percent.

Recent years have seen a decline in reading for pleasure, with the percentage of Americans who engage in the activity dropping by approximately 40 percent over the past two decades. However, the researchers found that shared reading groups and book clubs can offer additional benefits through social interaction, potentially reducing the risk of dementia among older adults.

Beyond the social and emotional aspects, research has uncovered associations between early reading and changes in specific brain structures. Early readers often exhibit larger volumes and cortical areas in brain regions associated with learning, emotional regulation, and cognition. Furthermore, readers tend to display better connectivity in white matter—the communication pathways between nerve cells—in language processing areas and increased cortical thickness in language-related brain regions.

The recent research roundup builds upon another study published in July in the journal Current Opinion in Psychology, which specifically examined the effects of reading fiction. While nonfiction reading may seem to offer more factual benefits, narrative fiction provides unique advantages. Engaging with someone else's world and perspective can foster better understanding of one's own experiences and those of others who differ significantly.

Raymond Mar, a co-author of the fiction-focused review, asserts that reading fantasy literature may help reduce prejudice while enhancing happiness, well-being, and social skills. Ultimately, the growing body of research underscores the numerous advantages of being an avid reader.
