Neuroscience: Why Reading Aloud Boosts Memory and Mental Health

MEDICENTER TV / ISTANBUL, TURKEY — DECEMBER 11, 2025

In the modern world, reading is almost exclusively a silent activity. However, new research suggests that by silencing our internal voice, we may be missing out on significant cognitive and physiological benefits.

According to historians and neuroscientists, reading aloud—a practice that was the norm in ancient times—is a powerful tool for memory retention, pain management, and emotional well-being.

A historical shift in literacy

Murat Tunalı, an expert on speed reading and comprehension, points out that the "silent reading" habit is a relatively recent development in human history.

"In the Ancient World, reading silently would have been considered utterly bizarre," Tunalı explains. "The shift began only after the invention of punctuation in the 10th century."

Tunalı asserts that modern society is "reading wrong." He argues that books are inherently designed to be vocalized, noting that "scientific studies prove that reading aloud offers far greater benefits than reading silently."

The "Production Effect": 90% retention rate

Recent scientific studies back these claims, highlighting what psychologists call the "production effect"—the dual action of speaking and hearing oneself that helps encode information into long-term memory.

A study from the University of Waterloo in Canada revealed startling statistics regarding memory retention. The research found that individuals remember 90% of the words they read aloud, compared to just 71% of words read silently. This suggests that for students and lifelong learners, vocalizing text is a superior study method.

Pain management and hormonal balance

The benefits extend beyond memory. In the United Kingdom, medical professionals are incorporating reading-aloud sessions into therapy groups for patients suffering from chronic pain, finding that the focus required helps alleviate physical discomfort.

Furthermore, a study conducted at ABC Federal University in São Paulo, Brazil, explored the physiological impact of storytelling on hospitalized children. Researchers found that reading aloud:

• Increased levels of oxytocin (the "feel-good" hormone).

• Significantly reduced cortisol (the stress hormone).

• Lowered reported pain levels.

"House of Healing for the Soul"

The connection between literature and health is not a new discovery; it is a rediscovery. The ancient library of Pharaoh Ramses II famously bore the inscription: "The House of Healing for the Soul."

While Western science only began to formally explore the health benefits of reading in the 15th century, modern medicine is now confirming that reading aloud creates meaningful connections, sharpens the mind, and serves as a form of non-invasive therapy.

Why you should start today

Whether for an adult seeking to improve focus or a parent bonding with a child, integrating reading aloud into daily life offers immediate benefits. Experts recommend recording sessions to track language development in children, while adults are encouraged to read complex texts aloud to enhance comprehension and alleviate daily stress.
