Internet addiction, refers to a behavioral disorder characterized by excessive and compulsive use of the Internet, often leading to negative consequences in various aspects of an individual's life. It is observed that a person who is addicted to internet, becomes dependent on using the Internet and needs to spend more and more time online to achieve the same ‘high’. This addictive behavior can manifest in various forms, such as excessive use of social media, online gaming, gambling, shopping, streaming, and other online activities. Other terms for this addiction include Internet addiction disorder (IAD) and net addiction.

Individuals struggling with internet addiction find it difficult to control their online usage, leading to neglect of responsibilities, strained relationships, decreased productivity and well-being. They may experience withdrawal symptoms when attempting to reduce or stop their internet usage, similar to those seen in other forms of addiction.
