For many people, the day doesn’t feel like it has begun without a hot cup of coffee in the morning. Whether under work pressure or fighting off afternoon drowsiness, coffee is often the first option that comes to mind. Until now, coffee was mostly seen as an energy booster or mood‑setter. But science has now given it an extraordinary “life‑saving” tag. A massive medical study spanning 43 years has revealed striking findings: people who drink coffee regularly in moderation have a significantly reduced risk of age‑related dementia.
According to a report published in the international medical journal JAMA, the likelihood of developing dementia was reduced by 18–20% among regular coffee drinkers. This was not a short study—it tracked about 130,000 people over 43 years. Researchers found that caffeine plays the most crucial role, as those who drank decaf coffee did not show similar benefits. Caffeine keeps brain neurons active, improves cognitive ability, and acts like a protective shield against cell damage.
Doctors caution, however, that drinking too much coffee can cause harm. The study suggests that two to three cups per day provide the maximum benefit. More than that may lead to insomnia, anxiety, or other issues. Coffee should be treated like a medicine—taken in moderation. Moreover, coffee alone cannot protect the brain; regular exercise, proper sleep, and nutritious food are also essential for maintaining memory.
Note: The benefits of coffee or caffeine may vary from person to person. Those with heart problems, high blood pressure, insomnia, or pregnancy should consult a doctor before changing their dietary habits. Excessive coffee consumption can have adverse effects.
