Coffee: The Secret To The Perfect Nap
If you start running low on brain power today, take a nap. But, make sure you have a cup of coffee beforehand! That sounds counterintuitive, but the coffee could help you feel alert when you wake up from that nap.
Researchers found people who drank coffee before taking a 20 minute nap performed better on memory tests than those who took a nap without the coffee.
Scientists say the caffeine kicks in just as the nap ends. The caffeine binds to molecules that make you feel tired, which makes you feel more alert.
