The day usually starts the same way. A tired glance at the clock, a slow walk to the kitchen, and a familiar routine meant to shake off the fog. For many people, that small ritual feels comforting, automatic, and harmless.
What rarely crosses the mind is that these daily choices might be doing more than helping us function before noon. Some habits follow us for decades, subtly shaping how our bodies and minds age over time.
Researchers are increasingly interested in these patterns, especially as dementia rates rise worldwide and scientists search for realistic ways to reduce risk without drastic lifestyle changes.
A long-term pattern
A large group of researchers from Mass General Brigham, Harvard T.H. Chan School of Public Health, and the Broad Institute set out to examine one of the most common habits on the planet.

Their focus was not on extremes, trends, or supplements, but on something already woven into daily life.
Using health data from more than 130,000 people followed over several decades, the team compared long-term beverage habits with later cognitive outcomes. The aim was to see whether consistency mattered more than intensity.
Their findings suggested that moderation, rather than excess, was associated with a lower likelihood of developing dementia later in life.
Why balance matters
The results did not point toward endless refills or cutting caffeine entirely. Instead, the data suggested a narrow range where potential benefits appeared strongest, with higher or lower intake offering no added advantage.

Researchers emphasized that the observed effect was modest. This habit alone cannot shield anyone from dementia, but it may support brain health as part of a broader lifestyle that includes mental stimulation, physical activity, and social engagement.
The bigger picture
Scientists involved in the research stressed that protecting the brain is a lifelong process. Education, learning new skills, and staying mentally active were all highlighted as important contributors alongside diet.
