Using a clever dual action effect, high concentrations of adenosine turn down the wake promoting regions in the brain and turn up the dial on the sleep inducing regions. When concentrations of adenosine peak, an irresistible urge for slumber will take hold. For most people, this happens after 1. You can mute the sleep signal of adenosine with caffeine.

Caffeine is removed from your system by an enzyme in the liver called cytochrome P4. A2. Based largely on genetics, some people have a more efficient version of this enzyme, allowing the liver to clear caffeine rapidly from the bloodstream. These rare individuals can drink an espresso with dinner and fall fast asleep at midnight. But as we age, it takes longer to remove caffeine, and we become more sensitive to its sleep disrupting influence. And note that decaffeinated does not mean non caffeinated. One cup of decaf usually contains up to a third of the dose of a regular cup of coffee. That means three to four cups in the evening are just as damaging to your sleep as one cup of regular coffee.

But in studies that I and others have performed, naps cannot salvage more complex functions of the brain, including learning, memory, emotional stability, complex reasoning or decision making. Also, naps are not recommended for those who have difficulties falling or staying asleep at night, since daytime naps can take the edge off your nighttime sleepiness.
