Heavy social media use has been linked to depression in teens and young adults. Studies have shown that heavy users, defined as using social media for more than 2 hours per day, are 300% more likely to be depressed than occasional users. There are a few reasons for this: passive social media use can lead to envy, fear of missing out, and lower self-esteem; exposure to cyberbullying increases the likelihood of depression; and excessive social media use replaces activities that are better for physical and mental health like social interaction, exercise, and quality sleep. The article recommends limiting social media use and seeking help from a mental health professional if heavy use is causing depression.
