In this research paper, we aim to investigate whether the teens’ usage of Instagram would bring about any bad or good influences on their mental and physical healthy. Thus, we design a questionnaire. The contents of the questionnaire are how much time they spent on the Instagram, using behavior, and using review. Through our analysis, the consequences that will follow from this questionnaire include positive impacts like shorten the distances among friends, release pressure, and record their lives. In contrast, instagram would cause some negative impacts like instagram would cause teenagers be distracted during class and lower their academic performances. arouse anxiety and jealousness after reviewing, and feel psychologically unbalanced. It can be referred that Instagram will both bring positive and negative influences on teenagers’ mental and physical health, so teenagers should learn how to establish positive value and attitude towards life.
