Excessive screen time and insufficient sleep can significantly influence a child's behaviour, often leading to various challenges in their daily life. Research indicates that prolonged exposure to screens—whether from tablets, smartphones, or televisions—can disrupt a child's natural sleep patterns, making it more difficult for them to settle at night. The blue light emitted by screens interferes with the production of melatonin, the hormone responsible for regulating sleep.

As a result, children who do not get adequate rest may exhibit increased irritability, difficulty concentrating, and heightened emotional reactions. They may struggle to manage their impulses, leading to conflicts at home and in social settings. Moreover, excessive screen time can contribute to a sedentary lifestyle, which is often linked to further emotional and behavioural issues.

It’s essential for parents to establish healthy boundaries around screen time and to promote regular bedtime routines. Encouraging activities such as reading or engaging in physical play can foster better sleep quality and, in turn, a more balanced and stable temperament during the day. Creating a harmonious balance between screen time, physical activity, and quality sleep can greatly enhance a child's overall well-being and behaviour.
