Considerable research shows coffee can dramatically affect your body and brain Studies link it to reduced risks of stroke, cancer, and type 2 diabetes, and it's also found to boost memory and teamwork.
But what if you need to solve a problem? Turns out coffee is good for that too.Depending on the type of problem you need to solve.
Say a customer's delivery date is in danger of being late. You need an idea. So you brainstorm. Any idea. Every idea. Thinking outside the box. Thinking with no box. That's divergent(发散的)thinking: free-flowing, unplanned, unstructured idea creation.
If you need lots of ideas, coffee won't help. But if you just need one great idea?If you just need to determine the best answer?
A study published in Consciousness and Cognition found one cup of coffee boosts problem-solving via convergent(聚合的)thinking: determining the best answer to a question. Even though participants didn't come up with more ideas, they solved problems faster. Researchers think this may be due to caffeine speeding up mental processing.
We found that participants who consumed about one 12-ounce cup of coffee showed significantly enhanced problem-solving abilities.
Why? The underlying mechanism is less clear. Research shows caffeine increases awareness, improves watchfulness, enhances concentration and lifts mood All those factors improve your problem-solving abilities.
Drinking a cup of coffee clearly works, but just keep in mind that a little more coffee is good, but a lot more may not be. Also consider how much coffee you drink regularly. A 2012 study found that within three days of consistent caffeine consumption, your body builds up tolerance, which means your body gets used to it and the effect weakens, including your problem-solving ability. Fortunately, if you cut back on coffee for a few days -around seven days or so-the original effects of coffee usually start to come back gradually.
So as with most things in life, consider the timing. See coffee as an occasional focus, mood, and analysis aid, especially when you need to solve a particularly difficult problem.
