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

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 people often tend to think that their "connections" have "perfect rosy lives" while they do not. Additionally, it can lead to Internet addiction. People may obsessively look through emails and messages, feeling stressed if they don't receive likes or replies on their posts, etc. This problem is formally termed Internet addiction disorder.
