Social media addiction is an unhealthy dependence on platforms like Facebook, Twitter, and Instagram. It manifests as overuse and difficulty abstaining from social media. The dopamine cycle of social media use can reinforce addiction through anticipation of and reaction to likes, comments, and shares. Signs include excessive time spent on social media, obsession even when not using it, withdrawing from other activities, and anxiety when unable to check social media. Social media addiction can cause mental health issues like low self-esteem, depression, loneliness, and sleep disorders. Breaking the addiction requires limiting social media use, spending more time offline with family and hobbies, and finding new activities to replace social media.
