Social Media: Is It Rotting Your Brain?

September 12, 2024

Key Takeaways Copied to clipboard!

  • Our attention spans have significantly shortened over the past two decades, with social media contributing to this decline by weakening our inhibitory control, but this change is not permanent and can be reversed by reducing social media use. 
  • While social media can trigger feelings of inadequacy and comparison, particularly regarding body image, the link between social media use and clinical depression or anxiety is smaller than often portrayed, and it does not necessarily replace in-person social interactions. 
  • Social media's addictive nature stems from its intermittent rewards, mimicking gambling, which makes it difficult to disengage, but finding alternative 'roach activities' and implementing 'speed bumps' can help regain control over usage.
