Excessive use of mobile phones can lead to addiction, which can cause a person to neglect important responsibilities, such as work, school, or social obligations. Constant use of mobile phones can lead to physical symptoms such as eye strain, headaches, and neck and shoulder pain, which can exacerbate addiction. The social isolation that can result from excessive mobile phone use can contribute to addiction, as individuals may rely on their phones as a source of entertainment and social interaction. The release of dopamine in the brain when a person receives a notification or engages in mobile phone use can contribute to addiction, as the brain associates these actions with a positive reward.
