Q. How does excessive use of technology impact the mental health of a user?

Answer =

Excessive use of technology leads to isolation as people don't get time to physically socialize. It sometimes also leads to anxiety and depression as by looking at picture perfect social media profile of others, people often tend to think that their "connections" have "perfect rosy lives" while they are not.
Excessive use of technology and Internet leads to addiction. People keep obsessively looking through emails and messages. They start feeling stress if they don't get some likes or replies on their posts etc. This problem is formally termed as Internet addiction disorder.
