Key Highlights

• The World Health Organization (WHO) has warned that excessive smartphone use may contribute to "smartphone brain" in children.
• Generative AI tools and social media algorithms may increase cognitive overload, reduce attention spans and encourage excessive screen dependence.
• Health experts say prolonged screen exposure can disrupt sleep due to blue light and overstimulation.
• WHO also highlighted a growing link between air pollution and an increased risk of dementia.
• Doctors recommend disciplined screen habits, parental supervision and balanced offline activities to protect children's health.

WHO Raises Concerns Over Children's Digital Habits

The World Health Organization (WHO) has raised fresh concerns about the growing impact of smartphones, generative artificial intelligence (AI) tools and social media platforms on children's mental and cognitive development.

According to health experts, excessive exposure to digital devices may contribute to a condition commonly referred to as "smartphone brain"—a non-medical term used to describe problems such as reduced attention span, cognitive overload, poor concentration and mental fatigue associated with prolonged smartphone use.

Experts say children are particularly vulnerable because their brains are still developing, making healthy digital habits increasingly important.

What Is 'Smartphone Brain'?

While "smartphone brain" is not an official medical diagnosis, experts use the term to describe a collection of symptoms linked to excessive smartphone use.

These may include:

• Difficulty concentrating.
• Shortened attention span.
• Mental fatigue.
• Memory problems.
• Reduced ability to focus on long tasks.
• Increased dependence on constant digital stimulation.

According to experts, continuous exposure to fast-moving digital content can make it harder for children to maintain attention during learning and everyday activities.

WHO Warns About Generative AI and Social Media Algorithms

Health experts also expressed concern about the increasing role of generative AI platforms and social media recommendation algorithms in children's daily lives.

These technologies are designed to keep users engaged by continuously providing personalised content, which may contribute to:

• Excessive screen time.
• Information overload.
• Reduced critical thinking.
• Increased digital dependency.
• Difficulty disengaging from devices.

Experts stress that AI technologies should be used responsibly and under appropriate supervision, especially by younger users.

Blue Light and Sleep Disruption

Another major concern highlighted by health experts is the effect of prolonged screen exposure on sleep.

Smartphones, tablets and other digital devices emit blue light, which can interfere with the body's natural sleep cycle by affecting the production of melatonin, the hormone that regulates sleep.

Poor sleep may lead to:

• Reduced concentration.
• Mood changes.
• Lower academic performance.
• Daytime fatigue.
• Long-term effects on physical and mental health.

Experts recommend avoiding screen use, particularly before bedtime, to promote healthy sleep patterns.

Medical Experts Recommend Balanced Screen Habits

To reduce the potential risks associated with excessive smartphone use, doctors recommend that parents and caregivers:

• Monitor children's daily screen time.
• Encourage regular outdoor activities.
• Promote reading and creative hobbies.
• Establish screen-free family time.
• Avoid device use before bedtime.
• Discuss responsible AI and internet use with children.

Experts emphasise that digital devices can be valuable educational tools when used in moderation and with appropriate guidance.

WHO Also Highlights Link Between Air Pollution and Dementia

In addition to concerns about digital health, experts discussed growing evidence linking air pollution to an increased risk of dementia.

According to the WHO, pollutants may contribute to:

• Brain inflammation.
• Oxidative stress.
• Long-term damage to brain cells.
• Increased risk of cognitive decline over time.

The organisation has called for continued efforts to reduce air pollution as part of broader public health strategies.

Other Health Advice Shared by Experts

Health specialists also addressed several common medical topics, including:

Fertility and IVF

On the occasion of World IVF Day, experts highlighted that:

• Female fertility generally declines after the age of 35.
• Routine bed rest after embryo transfer is usually unnecessary.
• Lifestyle habits and stress management can influence treatment outcomes.

Interventional Radiology Myths

Medical professionals clarified misconceptions regarding:

• Artery blockages.
• Varicose veins.
• Radiation exposure during diagnostic imaging.
• Cancer biopsies.

They noted that many common fears surrounding these procedures are not supported by current medical evidence.

Hernia and Appendicitis

Surgeons also addressed common myths, explaining that:

• Eating fruit seeds does not cause appendicitis.
• Timely treatment of appendicitis is important to prevent complications such as peritonitis.

Why This Matters

Children today are growing up in an increasingly digital environment where smartphones, AI-powered applications and social media are part of everyday life.

Health experts say the goal is not to eliminate technology, but to encourage healthy, balanced and age-appropriate use that supports learning while protecting mental, emotional and physical well-being.

Frequently Asked Questions (FAQs)

What is "smartphone brain"?

"Smartphone brain" is an informal term describing symptoms such as poor concentration, reduced attention span and mental fatigue linked to excessive smartphone use. It is not an official medical diagnosis.

What has the WHO warned about?

The WHO has highlighted concerns about excessive smartphone use, generative AI and social media algorithms potentially affecting children's cognitive development, sleep and attention.

How does blue light affect children?

Blue light emitted from digital screens can interfere with melatonin production, disrupting sleep and affecting overall health.

Does the WHO recommend banning smartphones for children?

The emphasis is on balanced and supervised use rather than an outright ban. Parents are encouraged to monitor screen time and promote healthy digital habits.

What other health issues were discussed?

Experts also highlighted links between air pollution and dementia, fertility awareness on World IVF Day, myths surrounding interventional radiology, and facts about appendicitis and hernias.
