"Sleep is like food for the brain. The better you sleep, the better you think, play, and grow."
— National Sleep Foundation
What is sleep?
Sleep is a state during
which conscious mental and physical activities are paused for couple of hours however
some sensory activities remain active. Sleep is a biological natural process which
you need to comply with for a healthy normal body and mind, like other
essential (food ) is necessary to survive a quality sleep also stand with it.
It can be considered as body recharge process.
As defined by the NIH, "Sleep
is a reversible, recurrent state of reduced responsiveness to external stimulation
that is accompanied by complex and predictable changes in physiology."
Quality sleep
When we talk about 'sleep,' what often comes to mind is simply the act of
resting and its duration However, not all sleep is equal. The concept we truly
need to focus on is quality sleep.
Unfortunately, in today's fast-paced world, the percentage of quality sleep
is declining due to many reasons, largely due to factors like excessive screen
time. So, what exactly is quality sleep? It's a sleep that is uninterrupted, deep, and lasts
for a sufficient number of hours, ultimately leaving you feeling refreshed and
revitalized – a state absolutely vital for overall well-being.
Given that our focus here is "children and sleep," for this age
group, quality sleep specifically refers to the recommended hours of rest as
per a doctor's sleep chart. This ensures their growing bodies and minds get the
restorative rest they need. Furthermore, for certain age groups of children,
body posture during sleep also plays a significant role in ensuring proper
breathing and spinal development, contributing to their overall sleep quality.
Importance of Sleep
in Kids
Sleep is like a multivitamin tablet for your kids — or better yet, a multivitamin+.
Quality sleep is essential for the physical, mental, and emotional
development of children. It affects nearly every part of the body —
from the brain, heart, and lungs to metabolism, immune strength, and emotional
resilience.
Research shows that sleep has a direct impact on alertness, attention,
learning capacity, mood regulation, vocabulary growth, and memory
retention.
What Research Tells
Us
Two major studies have examined how poor sleep affects children — both using
data from over 8,300 children aged 9–10 as part of the Adolescent
Brain Cognitive Development (ABCD) study, the largest long-term study
on child health in the U.S.
·
A study published in The
Lancet Child & Adolescent Health (July 29, 2022)
revealed that children who consistently slept less than 9 hours per
night showed:
o
Reduced gray matter volume in
brain regions responsible for memory, attention, and self-control
o
Greater risks of depression,
behavioral issues, and lower cognitive performance
o
These changes persisted even two years
later, highlighting the lasting impact of poor sleep on the developing
brain

·
A complementary study from the
University of Maryland (2022) reinforced these findings, noting that
children with insufficient sleep also exhibited:
o
Higher levels of stress, anxiety, and
aggressive behavior
o
Impaired decision-making and learning
abilities
o
Ongoing struggles with mental
focus and emotional regulation

Other Often Overlooked Benefits of Sleep in Children
Beyond what the research shows, quality sleep offers a wide range of
health benefits that parents may not always notice at first — but are
essential for a child’s long-term development.
When a child sleeps deeply and consistently, the body not only recharges but
also retains information, consolidates memory, and allows the
brain and body to repair and grow. Sleep is the silent foundation for thriving
childhood health.
Here are some key benefits that quality sleep unlocks:
·
Physical Growth
During sleep, the body releases growth hormone, which is vital
for physical development, tissue repair, and bone strength — especially during
early years and puberty.
·
Stronger Immune System
Sleep boosts the body’s defense system, helping children fight off infections
and reduce their risk of chronic illness.
·
Cognitive Development
A well-rested brain improves attention, learning, memory, and
decision-making skills.
·
Boosts Longevity
Consistent, quality sleep is linked with healthier habits and reduced long-term
health risks, which contribute to a longer, more active life.
·
Hormonal Balance
Sleep regulates the release of key hormones that control metabolism, mood, and
appetite — crucial during growing years.
·
Energy and Focus
Children who sleep well tend to be more alert, emotionally stable, and
energetic throughout the day.
·
Overall Well-being
From better emotional regulation to healthier body weight and stronger social
skills — sleep supports all areas of well-being.
WHO's Perspective on
Sleep
The World Health Organization (WHO) underscores the
importance of sleep as a pillar of public health. It
emphasizes that sleep contributes to a child’s physical, cognitive, and
emotional development and highlights the value of sleep
hygiene — encouraging families to create sleep-friendly routines and
environments as part of daily well-being.

Foundation and endorsed by health bodies such as the American Academy of Sleep
Medicine. Actual sleep needs may vary by child.
How to Improve and
Achieve Recommended Sleep in Children
As a parent, reaching the recommended sleep hours for your child may seem
challenging — but it’s far from impossible. It doesn't require drastic changes
or a “rocket science” approach. Like most healthy habits, consistency,
patience, and routine are key.
The secret lies in gradual habit-building and a willingness
to gently audit your family’s lifestyle. When dinner time, wind-down time, and
bedtime are clearly defined — and followed regularly — aligning with healthy
sleep patterns becomes much easier.
It’s also important to note: sleep recommendations are guidelines,
not rigid rules. A little flexibility is okay, as long as overall patterns
support rest and recovery.
Below are age-specific strategies to help improve sleep in children:
Infants (0–3 Months)
·
Create a calm and predictable sleep environment
·
Use soothing sounds, white
noise, or gentle rocking
·
A pacifier can sometimes help babies settle
·
Avoid loud noise or bright lights that may
interrupt rest
·
Ensure a quiet, undisturbed environment lasts at
least a couple of hours
Toddlers & Preschoolers
(1–5 Years)
At this stage, parents have more control over routines and
can shape the environment to support healthy sleep.
·
Fix a consistent sleep time and
start calming activities before it
·
Read bedtime stories to signal “wind-down” time
·
Use gentle massage or rocking
to relax them
·
Avoid screen exposure at least an hour before
bed
·
Maintain a predictable nighttime routine with
soft lighting and quiet surroundings
School-Aged Children
(6–12 Years)
This is where sleep challenges become more common. Global studies estimate
that handsome percentage of children in this age group experience sleep deficiency.
To help:
·
Establish a regular sleep schedule,
even on weekends
·
Turn off screens (TV, tablets,
phones) at least one hour before bed
·
Create a dark, quiet, and cool sleeping
space
·
Encourage calming activities before bed like
reading or light stretching
·
Be mindful of dinner timing and heavy
snacks close to bedtime
·
Help manage school-related stress or
anxiety through conversation, journaling, or relaxation exercises
·
Use soft, relaxing music or white noise
if it helps your child unwind
Adolescents &
Teenagers (13–18 Years)
Teenagers often face unique sleep disruptions due to screen
addiction, social life, late-night studying, and biological changes that shift
their natural sleep-wake cycles.
To support healthier sleep in teens:
·
Encourage consistency: A
regular sleep and wake time — even on weekends — helps reset the body clock.
·
Limit late-night screen use:
Blue light from phones and laptops interferes with melatonin production.
Consider setting “tech curfews” an hour before bed.
·
Promote mindful study habits:
Help teens avoid last-minute cramming or excessive stimulation before bed.
·
Create a sleep-supportive environment:
Keep the bedroom dark, quiet, and comfortable — and discourage doing homework
in bed.
·
Support emotional well-being:
Teen stress can significantly impact sleep. Encourage open conversation,
journaling, breathing techniques, or therapy if needed.
·
Limit caffeine: Avoid
caffeinated drinks in the evening, including coffee, tea, soda, and energy
drinks.
According to the American Academy of
Sleep Medicine, teenagers need 8–10 hours of sleep per night —
but most get significantly less.
