Participants in a University of Salford study reported feeling badly about themselves when comparing their own accomplishments in life with those of their online friends. Users also reported that they find it hard to relax or sleep after spending time on social networks.
If people are reporting negative feelings after using social media, why do they continue to log on? A study from Harvard University reveals that addiction may play a role. According to the study, when users are “self-disclosing” on social media, pleasure centers in the brain are activated. These pleasure centers are the same ones that light up during sex, or when someone eats or receives money.
