In recent years, many Social Network Services (SNS) websites and applications have flooded the Internet, our computers and smartphones. For some time, the main appeal of SNSs was the fact that they allow us to connect to friends whenever they are close by or in a remote location. Nowadays, understanding the repercussions of SNSs has become a very difficult task as SNSs are used not only for friendship connections but have also speeded out into many areas of our personal, social and economic life. In this thesis, the impacts of SNS on people will be discussed. Connecting to people through an SNS, checking your SNS account periodically, understanding how it affects our mental health and its impacts on society are some of the topics discussed here.
