Today, we are living in digital era surrounded by internet, gadgets like smartphones, tablet, laptops, smartwatches etc. The usage of Social networking sites is probably making us creative and independent but lonely too due to lack of face–to–face interaction, lack of spending time with kith and kin. Our expressions have become Emoji and our words have been replaced by texts. Social networking sites such as Facebook, Facebook messenger Twitter, Instagram and Whatsapp , You tube etc have occupied new generation of our society.On one hand these sites have positive effects but their negative consequences cannot be ignored. We conducted a questionnaire based study to investigate the impact of these social sites on lifestyle of 400 medical students.
