Hearing about SK Hynix's 200 million won profit triggers brain pain akin to 'four weeks of bed rest'

As the KOSPI index fluctuates sharply, Dr. Park Jong-suk, a psychiatrist, warns of FOMO (fear of missing out) and investment addiction risks. He explains that hearing about others' investment success activates the brain's pain response, comparable to physical injury, and highlights the dorsal anterior cingulate cortex (dACC) as the brain region processing social pain. With heightened SNS exposure in South Korea's concentrated capital region, Dr. Park analyzes how FOMO psychology intensifies, while sharing his own investment losses from impulsive trading. He advocates disconnecting from smartphones, avoiding dopamine-driven behaviors, and adopting healthier habits to prevent investment addiction.
