Why Reading Matters: What Decades of Research Say

Walk into any home where children are growing up, and you’ll notice a quiet contest. On one side, a small pile of picture books, maybe a stack of board books whose corners have already been chewed. On the other side, a glowing screen that offers infinite cartoons, games, and videos on demand. The contest often feels unfair: books are small, slow, and require patience. Screens are bright, loud, and endlessly new.

So the question naturally arises: in this age of abundant technology, why does reading still matter? Is it just a nostalgic habit, something we cling to because it feels wholesome, or does the research actually back it up? The answer is unambiguous. Across decades of studies, across cultures, and across developmental stages, the evidence is clear: children who grow up with books and stories develop stronger minds, better language, deeper empathy, and often a greater sense of connection to their families and communities, supporting a child’s cognitive, social, and emotional growth. Reading plays a vital role in shaping a child's emotional and intellectual wellbeing. Reading influences many aspects of a child’s life, offering stability and benefits that support their growth and well-being throughout their child’s life. The benefits of reading extend far beyond childhood, influencing a child's life well into adulthood. Reading can positively influence a child’s life experiences and resilience. Reading is a vital activity for child development, supporting literacy, social skills, and emotional growth.

Let’s take a closer look at what decades of research really say about the power of reading. Reading plays a crucial role in supporting a child's development, influencing cognitive, emotional, and social growth throughout a child's development. Reading is especially important for a child's development, as it shapes a child's language, social skills, and emotional experiences. Reading and storytelling at a young age foster a child’s language development. Introducing reading at a young age is essential for optimal developmental benefits.

Reading and the Developing Brain

Neuroscience has shown us that reading is not a natural skill — the brain wasn’t designed for it. Unlike walking or talking, which emerge biologically, reading must be taught and nurtured. Yet once it takes root, reading rewires the brain in remarkable ways. Early childhood reading experiences play a crucial role in supporting brain development, enhancing a child’s learning abilities and preparing them for future academic success.

Brain imaging studies at MIT and Stanford show that reading activates a network of regions across the brain: those that handle vision, language, memory, and executive control. These networks strengthen with practice, creating pathways that make other kinds of learning easier too. In young children, being read to regularly accelerates this process. Reading also fosters language development, which is closely linked to cognitive, social, and academic progress. During reading sessions, the spoken language children hear exposes them to rich vocabulary and complex sentence structures, supporting their language development. A 2015 study by the American Academy of Pediatrics found that children whose parents read aloud to them showed stronger activation in areas of the brain associated with narrative comprehension and imagination (Hutton et al., 2015).

In other words: when you read to a child, you are literally building their brain.

When I used to travel everyday in Mumbai local train, I used to observe a mother hold her toddler on her lap, reading aloud from a Hindi picture book called Ek, Do, Teen. Within a few days the toddler could just narrate the book (as best as he could). This simple act of parent child book reading is a powerful predictor of early language and literacy development. The child was barely two but repeated the numbers with delight, while the other passengers smiled quietly. Neuroscience would describe this as “phonological awareness” in action. But in that moment, it just looked like joy.

Language and Vocabulary Growth

Every parent knows that children are little sponges. The words they hear in early years shape how they speak, understand, and think later on. Early reading experiences are crucial for developing literacy skills and oral language skills, which are foundational for later academic success. But not all “word environments” are equal.

The landmark Hart and Risley (1995) study observed that by age 3, children from more language-rich households had heard millions more words than those from less talkative households — a difference that predicted later academic achievement. While the study has been debated and critiqued, follow-up research confirms the broad pattern: exposure to rich language in the early years matters enormously.

Books turn out to be one of the most effective tools for this exposure. Opportunities to read books together with children can significantly enhance their vocabulary, comprehension, and motivation to read. A 2019 study from the Ohio State University estimated that children who are read to daily enter kindergarten having heard 1.4 million more words than children who are rarely read to (Logan et al., 2019). That “million-word gap” can set the stage for smoother reading acquisition, stronger comprehension, and even broader general knowledge. Parent language input during reading not only supports language acquisition but also introduces children to new vocabulary, enriching their language environment.

Teachers often notice this first-hand. One told me, “The children who come in already familiar with stories — whether it’s Tenali Raman or The Very Hungry Caterpillar — are quicker to grasp new words. They connect ideas faster.” It’s not about which language or which book, but about having had the rhythm of words woven into their early years. Reading activities help develop language skills and support a child’s language growth. When we were selecting kindergarten for our kids, we made sure to check whether reading is part of their daily routine. The current kindergarten that our son goes to even has a reading corner within the class where a child can go and explore books whenever they want. A huge plus in my mind!

These experiences don’t just build vocabulary — they help children develop language skills that are essential for lifelong learning.

Cognitive Development and Academic Benefits

The benefits of reading extend well beyond vocabulary. Decades of international assessments confirm that children who read for pleasure outperform peers in academics, even after accounting for socioeconomic differences. The OECD’s Programme for International Student Assessment (PISA) repeatedly finds that reading enjoyment is more strongly correlated with academic success than even parental education level. Reading also supports cognitive development and leads to positive literacy outcomes, including improved comprehension and language skills. Reading exposes children to a wide range of topics, cultures, and viewpoints, helping them gain a deeper understanding of the world, complex ideas, and diverse perspectives.

Why? Because reading strengthens what psychologists call “executive function”: the ability to sustain attention, resist distraction, and hold information in working memory. Anyone who has watched a child focus on a long chapter book knows what training for concentration looks like. Additionally, reading motivation and reading for pleasure are key contributors to academic success and enhanced literacy outcomes, as children who are motivated to read are more likely to develop strong reading skills.

Researchers sometimes call this the “Matthew Effect in reading” (Stanovich, 1986): children who start strong in reading read more, learn more, and grow further ahead; those who struggle early often read less, fall behind, and the gap widens. Reading is a keystone habit — success in it unlocks success elsewhere. Research on literacy outcomes controlling for factors like socioeconomic status shows that early reading experiences help a child learn and make significant academic progress.

In Singapore, one primary school principal put it simply during a literacy workshop: “If a child becomes a confident reader by Primary 3, I can predict with high confidence they’ll succeed across subjects. If not, we have a big mountain to climb.”

Emotional, Mental Health and Social Growth

Books don’t just shape minds; they shape hearts.

Reading plays a crucial role in supporting children’s mental health and mental wellbeing, fostering emotional bonds, self-esteem, and healthy routines. In addition, reading supports children's language development, literacy skills, and motivation to read, laying a strong foundation for their future academic success.

Children’s literature is full of heroes, villains, friendships, betrayals, and moral dilemmas. Psychologists studying “Theory of Mind” — the ability to understand that other people have thoughts and feelings different from one’s own — find that children who read more fiction tend to score higher on empathy and perspective-taking tasks. One meta-analysis (Mar, Oatley & Peterson, 2009) linked frequent reading of stories with stronger social understanding. Through reading, children develop empathy and social skills by engaging in meaningful conversations and social interaction about the characters and their experiences.

Stories also give children a safe rehearsal space for emotions. A child reading about a character who faces loss, anger, or fear can explore those feelings in the safety of imagination before confronting them in real life. Books like The Day You Begin (Jacqueline Woodson) or Where the Wild Things Are (Maurice Sendak) are not just stories — they are emotional toolkits. Reading helps children understand and manage their own feelings, which contributes to better mental wellbeing.

In Kerala, a mother shared how her son, who struggled to talk about his anxieties, began opening up after reading The Boy Who Swallowed a Cloud. “He would point to the character and say, ‘That’s how I feel.’ It gave us a bridge we didn’t have before.” Through reading together, her son was developing empathy and emotional understanding. Research would call this “emotional regulation through narrative.” She just called it relief.

Reading as a Family and Cultural Practice

Research consistently shows that children who grow up in homes where books are visible and valued are more likely to become lifelong readers. The home environment, especially when parents engage in early book reading, plays a crucial role in supporting children’s literacy and language development. Research on parents' early book reading demonstrates that this practice significantly influences children's later language development and literacy outcomes, underlining its importance in early childhood education. A large-scale study of 27 countries (Evans et al., 2010) found that the number of books in the home was as strong a predictor of children’s educational attainment as parents’ occupation or income. Beyond the presence of books, shared reading, parent child book interactions, and rich parent language input during reading sessions foster children’s language and literacy outcomes, providing significant benefit to their overall development. A general rule in our household is that the books are always accessible and within grasp of our kids. Even the books that they may have read 20 times. We often find our children just hanging out with books even the younger one who can't read independently yet. One may wonder what's the point if young children cant read it but its developing positive relationship with reading and contributes to the development of their literacy skills.

But this isn’t only about having shelves full of hardbacks. In many parts of India and Southeast Asia, oral storytelling traditions remain vibrant: grandparents telling folktales, parents recounting epics, children absorbing values through narratives. These practices offer the same scaffolding for imagination and empathy that printed books do. Encouraging children to create and share their own stories, whether through storytelling, drawing, or song, helps encourage reading and benefits children’s creativity, language skills, and confidence.

One of the parents that we were working with via our reading program, used to tell me an anecdote of her and her cousins listening to their grandmother retell the story of Sukhu and Dukhu — a folk tale about kindness and resilience. The children would lean in, wide-eyed, repeating lines in chorus. There were no printed books in that courtyard, but the effect was the same: words carrying values, imagination, and connection. Shared reading and storytelling are enjoyable activities that can be part of a family’s daily routine, helping children learn, develop background knowledge, and explore different worlds, languages, and the lives of others. Making reading an enjoyable activity encourages both parents and children to bond and learn together, strengthening relationships and fostering a love of reading.

For example, a parent reads their favourite book aloud to their child, or a teacher encourages reading by inviting students to talk about their favourite book and why they love it. Reading books together, involving younger children in storytelling, and making shared reading a regular part of the day all help encourage reading and support children’s development.

These practices have long-term benefit for children’s lives, supporting their growth into successful adults who are equipped with empathy, knowledge, and the ability to navigate different worlds.

The Challenge of the Digital Age

Of course, we live in a time when books face stiff competition. Tablets, phones, and televisions offer endless stimulation. Some parents fear screens are destroying reading altogether.

The evidence is more nuanced. Studies show that digital skimming — the tendency to scroll, click, and skim rather than read deeply — is increasing, particularly among older children and teens. The neuroscientist Maryanne Wolf warns that this shift could weaken our capacity for “deep reading”: the slow, immersive, analytical thinking that books cultivate.

But the problem is not technology itself, rather imbalance. Screens can coexist with books if families set rhythms: bedtime stories remain sacred; library trips are regular; digital reading supplements but doesn’t replace print. The key is intentionality, not prohibition. Including the same book multiple times in a child’s daily routine can reinforce engagement and support deeper learning. Choosing books and activities that a child enjoys is essential, as fostering a child's enjoyment of reading can help build a lifelong love of books and learning.

Conclusion: Reading as Investment in Connection

Why does reading matter? Because it shapes the brain, builds language, strengthens academic skills, nurtures empathy, and binds families together. It is not just one skill among many — it is the soil from which many other abilities grow.

Decades of research affirm what parents have intuited for centuries: stories help children become not just smarter, but more human.

So when you sit with your child, book in hand, know this: you are not merely filling time before bed. You are building neural connections, expanding vocabulary, rehearsing empathy, and deepening bonds. Reading is one of the simplest, most powerful investments we can make in a child’s future.

And unlike apps that require updates, a well-loved book never runs out of charge.

FAQs

1. Why is reading so important for children?

Decades of research show that reading strengthens the brain, builds vocabulary, supports academic achievement, nurtures empathy, and deepens family bonds. It is not just about learning words — it shapes how children think, imagine, and connect with others.

2. At what age should I start reading to my child?

It’s never too early. Pediatricians recommend reading aloud from infancy, even if the child doesn’t yet understand the words. Babies benefit from hearing rhythm, tone, and repetition. Early reading lays the groundwork for language, attention, and bonding.

3. How much daily reading time is recommended?

A practical goal is 20–30 minutes a day for most children. For toddlers, this might mean a few short sessions. For older kids, it might be a longer stretch at bedtime. Research shows consistency matters more than length — a daily habit is key.

4. Does screen time replace reading?

No. While screens can provide entertainment and even some learning, reading builds deeper comprehension and attention skills. Unlike scrolling or watching, reading exercises the brain in ways that prepare children for critical thinking. The goal is not to eliminate screens but to balance them with daily reading.

5. What kind of books should I read with my child?

• Infants & Toddlers (0–3): Board books, rhymes, sensory books.

• Preschoolers (3–5): Picture books, repetitive stories, playful rhymes.

• Early Primary (6–8): Early readers, short chapter books, illustrated stories.

• Tweens (9–12): Novels, biographies, graphic novels, and any books that match their interests.

More importantly, the child should connect with the books. Reading aloud, especially in the early years is critical.

6. How does reading improve empathy in children?

Stories let children step into another person’s shoes. Research shows that children who read fiction regularly are better at understanding perspectives, emotions, and social situations — a skill known as “Theory of Mind.”

7. My child doesn’t enjoy reading. What should I do?

Start by understanding their interests, stage of life and development requirements. Ensure that they can relate to or are interested in the context of the book. Sometimes its the topic that interests them and the other times its the format. Do not hesitate to reach out to experts.

8. Does the number of books at home really matter?

Yes. Large studies across countries show that the number of books at home is linked with higher academic achievement. But it doesn’t have to mean buying hundreds — public libraries, book swaps, can all help build a “book-rich environment.” As a rule, keep the favorites and good quality books always at home.

9. What’s more important: reading every day or reading for long stretches?

Reading every day matters more. Even ten minutes a day builds a rhythm and habit that accumulates over time. Consistency makes reading feel natural rather than forced.
