Decades of Research Shows Coffee Makes You Healthier and Happier, But If You Want to Boost Your Energy Level and Memory, There's a 7-Day Catch

Coffee does plenty of cool things.

Coffee can reduce your risk of cancer up to 20 percent, your risk of type 2 diabetes by 30 percent, and your risk of Parkinson's disease by 30 percent. A study published in Circulation found that coffee can reduce the risk of stroke by 20 percent. A study of over 260,000 people conducted by the NIH found that people who drank four or more cups of coffee a day were nearly 10 percent less likely to become depressed than those who drank none.

Coffee can also make you smarter. While research has found little to no effect from ingesting caffeine prior to creating new memories, one study determined ingesting caffeine after a learning task improved memory recall up to 24 hours later.

Drinking a little coffee kick-start your day? Makes sense. So does drinking a little coffee later in the day to better retain what you've learned during the day.

But there is one catch.

...

The key is to reduce your intake for seven days to allow your adenosine receptor levels to reverse. (that's a good thing)

How great of a reduction you seek depends on how willing you are to cut your consumption. Just make sure you follow that approach for a whole week; one or two days will make relatively little impact on adenosine receptor levels, and therefore on the benefits when you resume your normal coffee routine.
