Sharper cognition
Moderate coffee consumption strengthens attention, reaction time and memory - essential tools for analysing complex data and synthesising knowledge.

Focus and energy
By blocking adenosine receptors in the brain, caffeine reduces fatigue and boosts energy levels, making it easier to stay focused during long hours of research or writing.

The limits of creativity
Although coffee sharpens focus, it can inhibit divergent thinking. Some studies suggest that the intense stimulus makes it harder to think freely and creatively outside the box.

The price of sleep
Coffee can keep you awake, but late consumption risks sabotaging sleep. Poor sleep, in turn, impairs memory and cognitive performance the next day.

Balance is key
1-3 cups daily is often the sweet spot where coffee's benefits shine without tipping over into nervousness, anxiety or addiction.

Conclusion
Coffee can be a scientist's best friend if used wisely. It boosts productivity and sharpens the mind, but requires moderation to avoid compromising sleep and creativity.
