A caffeine nap (also known as a coffee nap) is a type of sleep hack. A coffee nap is simply taking a quick 15-20 minute nap immediately after drinking a cup of coffee.
Several studies have shown that caffeine naps provide better post-nap alertness than caffeine or a nap alone. One study found that coffee naps were the most effective in improving alertness in sleep-deprived drivers.

To boost your energy, caffeine blocks the compound adenosine (which makes you sleepy) from binding to receptors in the brain. Researchers suspect caffeine naps work well because more adenosine is removed while you sleep, increasing caffeine’s impact on the body as you wake up.
Caffeine takes about 20 minutes to start working, so the caffeine does not interfere with the nap itself and the person waking up feels a double shot of energy from the caffeine and the rest. Try to drink the coffee without sugar so you don’t have a blood sugar spike right before taking the nap.
While it is not advisable to take coffee naps all the time, (caffeine can cause jitters and sleep problems) coffee naps are a good way to combat daytime sleepiness in times of need.
