This study uses the 2018 Canadian Internet Use Survey to examine reports of the negative effects individuals aged 15 to 64 experience because of their use of social networking websites or apps.

Six outcomes attributed to social media use are examined: lost sleep, trouble concentrating on tasks or activities, less physical activity, feeling anxious or depressed, feeling envious of the lives of others, and feeling frustrated or angry. Among all social media users aged 15 to 64, around one-fifth reported that in the previous 12 months, they had lost sleep (19%), gotten less physical activity (22%), or had trouble concentrating on tasks or activities (18%) as a result of their social media use. Around one in eight users (12% to 14%) reported feeling anxious or depressed, frustrated or angry, or envious of the lives of others.

Differences in the incidence of these outcomes across social media users in different age groups are of central interest. Compared with social media users in older age groups, larger shares of users in younger age groups report experiencing each of the six outcomes.

* I believe that younger group reported these experiences because they lack regulation in their self control in keeping boundaries or impulses in check. Lack of sleep, not eating, overall mood and mental health is disrupted.

* too much online decreases well being and physical health. Lack of movement puts strain on fine and motor skills , eye strain, not playing outside getting fresh air, being outside with other people.

* creates a falsehood that your life is great all the time. There are moments in life that are only perceived as happy , having people validate your feelings online can be too much. Lower self esteem , too many friends online vs real life.
