A child’s physical growth, emotional well-being, and cognitive development are partly supported by sleep. However, sleep problems have rapidly become a significant health issue for children today. Irregular school hours, early morning announcements, virtual classes, and additional screen time have severely disrupted children's sleep patterns.

Spending more time with screens in the evening interferes with the child's melatonin production, a hormone that induces drowsiness and prepares the body for sleep. Irregular daily routines confuse their internal clocks, making it difficult to fall asleep and stay asleep. As a result, many children experience fatigue, difficulty concentrating, mood changes, and declining academic performance. Recognising the causes of disrupted sleep is the first step to improving sleep habits and long-term health.

"Considering how widespread irregular sleep schedulesand gadget usage are, it is crucial to understand their impact on sleep,” Dr Poonam Sidana, Director of Neonatology and Paediatrics at CK Birla Hospital, Delhi, tells Moneycontrol. Early detection, parental awareness, and consistent routines are key to preventing sleep disorders and ensuring children's health and growth.

Causes of sleep disorders in children

1. Irregular school timings disrupt natural sleep cycles

Changing school schedules, early classes, varying test times, and holidays confuse children's body clocks. Irregular routines make it challenging for children to sleep and wake up on time.

2. Excessive screen time overstimulates the brain

Devices like cell phones, tablets, and gaming consoles emit blue light that impairs melatonin's sleep-inducing function. Children who use these devices at night keep their brains alert, delaying sleep by 1-3 hours.

3. Social media generates emotional hyperactivity

Children today experience "fear of missing out" (FOMO) when they see things online. Their minds remain engaged and "awake" late at night due to online activities.

4. Physical inactivity reduces healthy fatigue

Today's children spend most of their time indoors, resulting in less physical activity and minimal exposure to sunlight, which are essential for sleep regulation and preparing the body for sleep.

5. Academic pressure causes bedtime procrastination

Excessive homework and late-night studying lead children to go to bed later. They develop a habit known as "bedtime revenge procrastination," seeking alone time by staying up late.

6. Lack of sleep leads to behavioural and learning problems

Sleep deprivation in children can result in temperamental behaviour, concentration difficulties, fatigue, and hyperactivity. In some cases, sleep deprivation can cause ADHD-like symptoms.

What parents can do

Establish fixed sleep and wake-up times: Consistent daily routines help adjust the body clock.

Avoid screens at least one to two hours before sleep: This allows melatonin production.

Encourage daily outdoor activities: Physical activity promotes better sleep.

Keep gadgets out of the sleeping area: Ensure the bedroom is a sleep-friendly environment.

Use warm light in the evening: Signals the approach of bedtime.

Create a relaxing bedtime routine: Reading and storytelling can help children with sleep disorders, potentially preventing obesity, mood issues, and poor academic performance.

Consistent efforts can reset a child’s sleep cycle and prevent long-term health problems such as obesity, mood disorders, and poor academic performance.
