Study: Speaking Multiple Languages Associated With Slower Aging

  • The journal Nature Aging published findings that multilingual individuals are half as likely to show accelerated biological ageing, reporting a decreased risk of accelerated ageing.
  • An international team analysed data on 86,000 participants aged 51–90 across 27 European countries, using a computational method to calculate each participant's biobehavioural age gap.
  • The researchers found that active multilingualism showed stronger benefits than people who once studied another language in school, with effects persisting after adjusting for age, health, environment and supporting cognition .
  • Policy experts note that findings could inform public health and education policies, with Susan Teubner-Rhodes suggesting they might 'encourage people to go out and try to learn a second language, or keep that second language active,' and May emphasizing the benefits of being bi/multilingual.
  • Despite past debate, previous small studies produced inconsistent results, and many English-speaking countries have a monolingual proportion up to 75 percent, facing ageing populations and healthcare strain.
