How to practice Learn a language
Practice 30–60 minutes daily or several hours weekly using immersive methods (conversation, media, or tutoring). Combine digital tools (e.g., Duolingo, Babbel) with real dialogue or group classes. Aim for consistent exposure over years rather than brief bursts. Even partial fluency yields measurable neural benefits.
The evidence behind Learn a language
Bilingualism is consistently linked to greater cognitive reserve and delayed onset of dementia by 4–5 years. Language learning enhances executive function, working memory, and attentional control through continuous task switching and neural recruitment. Neuroimaging confirms increased gray matter density in language and cognitive-control regions. Evidence applies across age groups, with strongest effects from sustained engagement.
