Social media use has been linked to increased rates of depression. Frequent social media users are more likely to be depressed than less frequent users. The ways social media may cause depression include lack of meaningful social interaction, increased social comparison and envy of others' lives, and overuse of multiple platforms. However, people continue using social media heavily due to its ability to trigger rewards in the brain and its role in modern communication. Reducing social media use is difficult but may improve well-being and decrease depressive symptoms.
