To understand how a coffee nap might work, we need to look at how the body processes caffeine. When you drink a coffee, the caffeine stays in the stomach for a while before moving to the small intestine. It is from here that caffeine is absorbed and distributed throughout the body. This process, from drinking to absorption, takes 45 minutes. Once you wake up from your nap, not only do you experience the hit, your body feels the effects of the caffeine hours later. Although caffeine is broken down in the liver, half of it remains in the blood for 4-5 hours after drinking a moderate amount (equivalent to two large cups of brewed coffee). It takes more time to eliminate greater amounts of caffeine from the body.
