Excessive Instagram use may not only affect how you view your body but also how your brain recognizes it as your own. A new study by researchers at Università Cattolica in Milan suggests that heavy social media use could erode your sense of self, potentially making you feel less at home in your own body. The findings are published in the journal Computers in Human Behavior.
Self-Identity in the Digital Age
While social media platforms have long been scrutinized for their impact on body image and mental health, this research suggests the issue runs deeper than surface-level insecurity. Years of exposure to selfies, filters, and edited images may blur our ability to recognize our own faces as unique. In the digital age, where faces start to look alike, it might become harder to remember what makes us distinct.
Mental health challenges among adolescents and young adults are growing. According to the World Health Organization (WHO), one in seven adolescents and one in eight adults suffer from a mental disorder. Body dissatisfaction, increasingly common in this digital era, is linked to poor mental health and a higher risk of eating disorders, depression, social anxiety, and low self-esteem. Social media, particularly Instagram, has turned the body into a key instrument for communication and self-representation, creating unrealistic aesthetic standards through filters, likes, and visibility metrics. However, the new research indicates that the problem goes beyond evaluation—it affects how we construct our sense of identity.
The Study
Researchers aimed to understand the relationship between Instagram use and the brain's processes for recognizing one's own face. They recruited 95 young adults (average age 26) and used virtual reality techniques to temporarily create the sensation of inhabiting someone else's body, measuring how fluid or rigid participants' bodily boundaries were. The results showed a "dose effect": the longer a person's history of Instagram use, the more likely they were to perceive a stranger's face in virtual reality as their own.
"It is through our faces that we recognize ourselves in the mirror, construct our individuality, and are recognized by others," said Professor Giuseppe Riva, director of the Humane Technology Lab at Università Cattolica. "The association does not emerge in any bodily representation, but precisely in the part of the body most closely linked to the sense of who we are."
Researchers described this as the "erosion of bodily identity hypothesis," suggesting that prolonged exposure to digital environments where faces resemble one another may hinder our ability to remember what makes us unique.
Dr. Maria Sansoni, who led the study, noted: "Participants belong to the first generation to grow up with social media—they began using these platforms in late adolescence and have integrated them into daily life for nearly a decade. If associations with bodily identity processes are already emerging in these young adults, the question arises for new generations who encounter these technologies at an increasingly early age."
The authors caution that the study does not prove Instagram directly causes mental health issues or that these changes are necessarily harmful, but it opens a conversation about the relationship between technology and identity.
