Research shows that coffee can now make you smarter and more creative.

While coffee might not improve your brainstorming skills, it can speed up the process of identifying the best solution to an issue. Numerous studies have demonstrated that coffee has a profound impact on brain and body function.

According to a Circulation study, coffee can cut the risk of stroke by 20%. According to a different study, drinking coffee can lower the risk of Parkinson’s disease by 30%, type 2 diabetes by 30%, and cancer by up to 20%. Intriguingly, coffee can also improve your intelligence and teamwork skills. After a learning exercise, caffeine consumption increases recollection for up to 24 hours, according to one study published in Nature Neuroscience; another study published in the Journal of Psychopharmacology demonstrates that coffee improves interpersonal collaboration.

But what happens if you have an issue to solve?

It turns out that coffee has the same benefits. Depending on the kind of issue that needs to be resolved. Coffee won’t provide you with a lot of ideas if you need them.

But what if you only require one brilliant idea?

If finding the optimal response is all that’s required.

The caffeine equivalent of one cup of coffee, excellent news for soda lovers like Warren Buffett, has been shown in a study published in Consciousness and Cognition to improve problem-solving via convergent thinking, or choosing the optimal response to a given topic.

While participants did not generate more ideas, they solved problems more quickly through insight (think “Aha!” instead of a step-by-step examination), which the researchers speculate may be related to caffeine’s ability to speed up brain processing. Just remember that a little extra coffee doesn’t always mean more. (As is often the case, “more” is correlated with “better” until it’s not.)

Do you feel more focused and observant? That’s fantastic. Are you twitchy and wired? Yes, indeed.

Take into account the total amount of coffee you drink.

According to a 2012 study, the amount of adenosine, nicotinic, and muscarinic receptors—a neurotransmitter that regulates neuronal excitability—significantly rises three days after regular caffeine consumption. Put simply, the impact fades when your body develops a tolerance for it.

Regularly consuming excessive amounts of coffee can reduce the benefit of an increase in problem-solving abilities. (Luckily, after cutting back on coffee for seven days, alterations in adenosine receptor levels usually reverse.)

Thus, think about the timing, like with other things in life. Consider coffee as a mood, analytical, and focus enhancer on occasion, particularly when faced with a particularly challenging challenge to solve.
