2–3 Cups Of Coffee May Boost Brain Function, Study Suggests

Your daily coffee habit

might be doing more than waking you up.

A recent study suggests that drinking two to three cups of coffee a day could improve cognitive ability, including focus, memory, and alertness.

Researchers observed that moderate coffee consumption was linked to better mental performance compared to both non-drinkers and excessive consumers.

In simple terms: a little coffee helps — too much doesn’t.

Why this matters: With increasing screen time, long work hours, and exam pressure, many young adults rely on caffeine to stay sharp. Scientific backing for moderate consumption adds nuance to the debate around coffee and health.

However, experts caution that benefits depend on quantity. Excessive intake may increase anxiety, disturb sleep, and impact heart health.

The key word is moderation.

Coffee contains antioxidants and caffeine, which stimulate the central nervous system. That boost can enhance reaction time and concentration — temporarily.

But it’s not a substitute for sleep, nutrition, or stress management.

So yes, your morning brew may support brain function.

Just don’t turn it into five.
