Excessive use of digital technology, like social media, by adolescents can cause disruptions in their physical and mental health, in sleeping patterns, their weight and levels of exercise and notably in their academic performance. Research has continued to demonstrate that long hours spent on mobile devices have shown a positive relationship with an increase in teenagers' BMI and a lack of physical activity. Moreover, excessive internet usage has been linked to lower grades compared to users who don't spend an excessive amount of time online, even with a control over age, gender, race, parent education and personal contentment factors that may affect the study. In a recent study, it was found that time spent on Facebook has a strong negative relationship with overall GPA. The use of multiple social media platforms is more strongly associated with depression and anxiety among young adults than time spent online. The analysis showed that people who reported using the most platforms (7 to 11) had more than three times the risk of depression and anxiety than people who used the fewest (0 to 2). Social media addiction and its sub-dimensions have a high positive correlation. The more the participants are addicted to social media, the less satisfied they are with life.

Though research has shown evidence that social media plays a role in increasing political polarization, it has also shown evidence that social media use leads to a persuasion of political beliefs.  An online survey consisting of 1,024 U.S. participants was conducted by Diehl, Weeks, and Gil de Zuñiga, which found that individuals who use social media were more likely to have their political beliefs persuaded than those who did not.  In particular, those using social media as a means to receive their news were the most likely to have their political beliefs changed.  Diehl et al. found that the persuasion reported by participants was influenced by the exposure to diverse viewpoints they experienced, both in the content they saw as well as the political discussions they participated in.  Similarly, a study by Hardy and colleagues conducted with 189 students from a Midwestern state university examined the persuasive effect of watching a political comedy video on Facebook.  Hardy et. al found that after watching a Facebook video of the comedian/political commentator John Oliver performing a segment on his show, participants were likely to be persuaded to change their viewpoint on the topic they watched (either payday lending or the Ferguson protests) to one that was closer to the opinion expressed by Oliver.  Furthermore, the persuasion experienced by the participants was found to be reduced if they viewed comments by Facebook users which contradicted the arguments made by Oliver. 
"Social media" is a way for people to communicate and interact online. While it has been around since the dawn of the World Wide Web, in the last 10 years or so we've seen a surge in both the number and popularity of social media sites. It's called social media because users engage with (and around) it in a social context, which can include conversations, commentary, and other user-generated annotations and engagement interactions.
Social media marketing has increased due to the growing active user rates on social media sites. For example, Facebook currently has 2.2 billion users, Twitter has 330 million active users and Instagram has 800 million users. One of the main uses is to interact with audiences to create awareness of their brand or service, with the main idea of creating a two-way communication system where the audience and/or customers can interact back; providing feedback as just one example. Social media can be used to advertise; placing an advert on Facebook's Newsfeed, for example, can allow a vast number of people to see it or targeting specific audiences from their usage to encourage awareness of the product or brand. Users of social media are then able to like, share and comment on the advert, becoming message senders as they can keep passing the advert's message on to their friends and onwards.
Observers have noted a range of positive and negative impacts of social media use. Social media can help to improve an individual's sense of connectedness with real or online communities, and can be an effective communication (or marketing) tool for corporations, entrepreneurs, nonprofit organizations, advocacy groups, political parties, and governments. At the same time, concerns have been raised about possible links between heavy social media use and depression, and even the issues of cyberbullying, online harassment and "trolling". Currently, about half of young adults have been cyberbullied, and of those, 20% said that they have been cyberbullied regularly. Another survey in the U.S. applied the Precaution Process Adoption Model to cyberbullying on Facebook among 7th grade students. According to this study, 69% of 7th grade students claim to have experienced cyberbullying, and they also said that it was worse than face-to-face bullying. Both the bully and the victim are negatively affected, and the intensity, duration, and frequency of bullying are the three aspects that increase the negative effects on both of them.
