A new clinical trial in the UK has discovered that playing the puzzle game Tetris can significantly reduce intrusive memories in healthcare workers exposed to trauma. The study focused on NHS staff who witnessed traumatic events during the COVID-19 pandemic .
Researchers used a technique called “imagery-competing task intervention,” where participants briefly recalled a traumatic memory and then played Tetris for 20 minutes. The visual processing required for the game disrupts the brain’s ability to solidify the distressing image, leading to fewer flashbacks .
This simple, digital intervention proved highly effective, with participants reporting a major drop in PTSD symptoms compared to control groups. The findings suggest a scalable and accessible way to support the mental health of frontline workers facing ongoing stress .
