Finger length may hint at risk of smartphone addiction in young adults

This observational study looks at whether the ratio of index to ring finger length and handgrip strength are linked to symptoms of problematic smartphone and internet use. Researchers measured these traits in 173 university students aged 17–26 from Turkish, Middle Asian, African, and Asian backgrounds. Participants completed surveys about their smartphone and internet habits. The goal is to better understand biological factors that might relate to addictive technology use.
