May is National Share-a-Story Month, and Mattress Online is highlighting the science-backed benefits of bedtime stories for children. Beyond their nostalgic charm, these timeless tales promote better sleep, emotional regulation, and academic readiness. Sleep scientist Hannah Shore explains how this simple ritual supports children’s well-being, offering a calming alternative to screen time in an increasingly digital world.

Stories as sleep cues

A bedtime story is more than a tradition; it’s a powerful signal to the body that it’s time to rest. “A bedtime story is the go-to wind-down routine for lots of parents. Tried, tested and passed down through generations,” says Hannah Shore, Head of Sleep Science at Mattress Online. “Having a good wind-down routine before bed allows the body and brain to relax and calm down. This calm time tells the body it should start to get ready for sleep, slowing down that heart rate, bringing that core body temperature down and relaxing the mind, all signals to help prompt the body to start producing sleep hormones, such as melatonin.”

Research underscores this. A 2021 study found that consistent bedtime routines, including storytelling, established as early as 3 months, lead to fewer night-time awakenings, reduced sleep problems, and longer sleep durations by age 3. These routines create a predictable environment, helping children associate stories with rest.

Emotional regulation through storytelling

Bedtime stories also support emotional health. Language-based bedtime routines, like storytelling, reduce behavioural issues such as anxiety, aggression, and social withdrawal. This is linked to increased REM and lighter sleep stages, which aid emotional processing and memory consolidation, crucial for mental health and learning.

Story time versus screen time

In contrast to screens, which emit blue light that suppresses melatonin and disrupts sleep, bedtime stories foster relaxation. A 2017 study published in Scientific Reports confirmed that screen exposure before bed delays sleep onset and reduces sleep quality in children. Storytelling, often shared in a cosy, screen-free setting, strengthens the parent-child bond, creating a sense of safety that promotes calm and better sleep.

Benefits beyond bedtime

Regular storytelling boosts language skills, creativity, and academic readiness. Children exposed to frequent bedtime reading develop larger vocabularies, better pronunciation, and greater fluency. These skills translate to improved self-confidence and school performance. Storytelling also encourages imagination, as children visualise characters and settings, fostering creative thinking.

Choosing the right books

Not all stories are equal for bedtime. Gentle, predictable tales with soothing rhythms or repetition are most effective. Nature-themed books, stories with low-stimulation visuals, or those exploring emotions calmly help signal to the brain that it’s time to wind down. Classics like The Gruffalo by Julia Donaldson or Guess How Much I Love You by Sam McBratney are popular choices for their calming cadence.

A timeless ritual

Hannah Shore summarises the impact: “In a world of distractions and screen time, the simple ritual of a bedtime story can be incredibly powerful. Not only does it support healthier sleep, but it also strengthens the bond between parent and child, creating a sense of safety and calm that’s essential for emotional wellbeing.” As National Share-a-Story Month encourages families to share tales, the evidence is clear: bedtime stories are a small act with big rewards, nurturing sleep, emotions, and learning.
