Research has also shown that social media use may not have an effect on polarization at all . A U.S. national survey of 1,032 participants conducted by Lee et. al found that participants who used social media were more likely to be exposed to a diverse number of people and amount of opinion than those who did not, although using social media was not correlated with a change in political polarization for these participants .
Criticisms of social media range from criticisms of the ease of use of specific platforms and their capabilities, disparity of information available, issues with trustworthiness and reliability of information presented, the impact of social media use on an individual's concentration, ownership of media content, and the meaning of interactions created by social media. Although some social media platforms offer users the opportunity to cross-post simultaneously, some social network platforms have been criticized for poor interoperability between platforms, which leads to the creation of information silos, viz. isolated pockets of data contained in one social media platform. However, it is also argued that social media have positive effects such as allowing the democratization of the Internet while also allowing individuals to advertise themselves and form friendships. Others have noted that the term "social" cannot account for technological features of a platform alone, hence the level of sociability should be determined by the actual performances of its users. There has been a dramatic decrease in face-to-face interactions as more and more social media platforms have been introduced with the threat of cyber-bullying and online sexual predators being more prevalent. Social media may expose children to images of alcohol, tobacco, and sexual behaviors[relevant? – discuss]. In regards to cyber-bullying, it has been proven that individuals who have no experience with cyber-bullying often have a better well-being than individuals who have been bullied online.
According to a study released in 2017 by researchers from the University of Pittsburgh, the link between sleep disturbance and the use of social media was clear. It concluded that blue light had a part to play—and how often they logged on, rather than time spent on social media sites, was a higher predictor of disturbed sleep, suggesting "an obsessive 'checking'". The strong relationship of social media use and sleep disturbance has significant clinical ramifications for a young adults health and well-being. In a recent study, wehave learned that people in the highest quartile for social media use per week report the most amount of sleep disturbance. The median number of minutes of social media use per day is 61 minutes. Lastly, wehave learned that females are more inclined to experience high levels of sleep disturbance than males. 
Social media are interactive computer-mediated technologies that facilitate the creation and sharing of information, ideas, career interests and other forms of expression via virtual communities and networks. The variety of stand-alone and built-in social media services currently available introduces challenges of definition; however, there are some common features:
