Work from University College London, Trinity College Dublin, Japan and a 13-country brain-clock study links dance, music, art, gardening, reading and language learning with slower biological aging and stronger cognition. Variety, they find, often beats one perfect pastime.

Among 84,267 adults aged 50 and over in 24 countries, hobby participation was associated with better memory, orientation and numeracy. In Japan one mid-life hobby was linked to about a 19 per cent lower risk of disabling dementia and several hobbies to about 23 per cent.

What Brain Clock Research Now Shows

Teams at the Global Brain Health Institute trained machine-learning clocks on recordings from 1,240 people, then tested 232 experts and learners in tango, music, visual art and strategy games across 13 countries.

Among 3,556 UK adults, taking part in arts and cultural activities at least weekly was associated with an approximately 4 per cent slower pace of epigenetic ageing. Experts in all four creative domains showed younger-looking brains. Tango produced the largest gap, about seven years, with musicians, artists and gamers several years younger than calendar age.

Senior author Agustin Ibanez said 'creativity emerges as a powerful determinant of brain health, comparable to exercise or diet'.

A Trinity analysis of healthy adults aged 40 to 59 in the PREVENT Dementia programme found stimulating activities, including an instrument, travel, reading and a second language, linked to stronger cognition even in people carrying the APOE e4 gene.

Physical inactivity and social isolation sit among 14 modifiable risks in the 2024 Lancet Commission, which together are linked to about 45 per cent of dementia cases worldwide.

Hobbies That Stack Movement Novelty and Company

Research increasingly points to activities that combine movement, learning and social interaction as potentially useful for brain health.

Pastimes that combine exercise, new skills and other people may be especially useful for brain health. These ten appear across recent studies.

  1. Dance — movement, memory and company in one session, with tango showing the largest brain-age gap.
  2. Walking or aerobic exercise — the plain option; the session that works is the one a person will repeat.
  3. Gardening — outdoor work and planning; even 20 minutes has been shown to raise BDNF.
  4. Music — listening or playing both count.
  5. Reading and writing — standard cognitive hobbies linked with later onset of decline.
  6. Learning a language — extra mental load, useful in mid-life as well as later life.
  7. Puzzles, cards and strategy games — keep flexibility and working memory in use.
  8. Knitting and crafts — fine motor sequences with low-stakes problem solving.
  9. Visual art — drawing or painting; another creative domain with a younger clock age in experts.
  10. Clubs and social activity — cuts isolation, a late-life risk on the Lancet list.

Why Starting Early Still Matters

A Japanese study with a median 11-year follow-up found that having hobbies in mid-life was associated with a lower risk of disabling dementia. Stable hobby habits across 24 countries predicted better cognition.

English Longitudinal Study of Ageing data on 6,854 people aged 50 and over found hobby use linked to about half the odds of a persistently low cognitive path (odds ratio 0.46) and a slower slide in orientation, though not in every domain.

These findings suggest mixed, repeatable pastimes may be useful for mid-life and later-life brain health, not as a substitute for blood pressure, hearing or vision checks.

The World Health Organization says 57 million people lived with dementia in 2021, with nearly 10 million new cases each year.

No study claims a hobby blocks disease alone. People who keep several stimulating activities going tend to show better cognitive health.

Frequently Asked Questions

  • What types of hobbies are beneficial for cognitive health?
    Hobbies that involve creativity, movement, and social interaction, such as dance, music, art, and strategy games, are beneficial for cognitive health.
  • How do hobbies affect cognitive ageing?
    Engaging in hobbies can slow the pace of cognitive ageing by keeping the brain active and promoting neuroplasticity.
  • Can hobbies prevent dementia?
    While no hobby can prevent dementia alone, maintaining a variety of challenging activities can help keep the brain sharp and may reduce the risk of cognitive decline.
