During the lockdown, children's online education started via mobile phones. Due to online classes, parents bought separate mobile phones for their children.

In this way, mobile phones reached the hands of teenagers under the pretext of studying. Children started misusing them. Even young children started becoming active on social media like Instagram and Facebook. Due to mobile phones, the habit of playing outside has decreased in children, which has hindered their physical and mental development, as various studies have shown.

The World Health Organization recommends not using screens for children under two years of age, and recommends that children between two and four years of age should not have more than one hour of screen time a day under the supervision of a parent or caregiver. Effects of mobile phone use on children's health: - Children have started to experience problems such as dry eyes, nearsightedness, and blurred vision after looking at the screen for a long time.

– Using mobile phones at night affects the melatonin hormone, which increases insomnia.

– Spending too much time on mobile phones reduces physical activity, which is increasing obesity in children.

– Social media and gaming addiction are causing children to show signs of stress and anxiety.

– Excessive screen time reduces children's ability to concentrate, which affects their studies.

– Violent games or pornographic content are increasing sexual perversion and aggression in children's behavior.

– Spending too much time on mobile phones makes children distance themselves from family and friends, which prevents them from developing social skills.
