The term narcissism comes from the mythical Greek character Narcissus, who fell in love with himself after he saw his own image reflected in the water. It is when an individual develops the exaggerated feelings of self-importance, self-loving and excessively high self-esteem. Besides, in combination with these, it is a personality trait that is characterized with low empathy towards others. People scoring high on narcissism have difficulty maintaining healthy, long-term close relationships and have a tendency to behave aggressively in response to critical feedback. In extreme cases, narcissism can be a clinical disorder affecting mental health, Physical health and well-being of an individual. Narcissistic people have a number of difficulties maintaining healthy and strong interpersonal relationships. Social relationships are fundamental to fulfilling core human needs, such as the need to belong. They are also implicated in psychological well-being, mental health, and physical health. Now a days, people are increasingly getting connected to social networking websites like Facebook, Twitter, Whatsup and Instagram, where users themselves publish content publicly in contrast to the traditional mass media (TV, Radio etc.) that are being relayed by the government or corporate controlled entities. Excessive engagement with these social media may create the symptoms of self-obsession, self-centric attitude and low empathy toward others. This is mainly attributed to the relative isolation from the society because of spending a bigger time on this virtual media and simultaneously ignoring or avoiding the social interactions on ground. This distortion in self identity usually leads to distortion in social identity of the individual; another serious concern for the society at large. This is because the ever growing influence of social media results into construction and reconstruction of self identity that may lead to narcissism. My research paper deals analytically and in depth the issue of how the excessive use of social media and consequent social isolation of an individual have a high possibility to culminate into narcissistic behavior in him/her which, if not handled properly at the right time, may be turned into mental or physical health problems(symptoms of narcissistic personality disorder). The main objective is to find out if narcissism could result into health concern or threat to the mental-physical well-being of a person and how does it do. Methodology adopted here includes the questionnaire survey based Narcissistic Inventory Test, which is most suitable one. This comprises both male and female as subjects. The challenges emerged due to the various dimensions of the issue of narcissism as a health concern and its interrelationships with social media are critically analyzed in this paper.
