Wise Wednesday Brain Byte: Coffee or Nap?

Knowing the answer, yet exhausted and hoping for a quick fix, I posed the question anyhow:  Shall I make a pot of coffee and suffer the consequences of staying up too late tonight and suffering fatigue AGAIN tomorrow; or should I take a nap?

A study published in the journal Behavioural Brain Research evaluated the performance of 3 groups of people:

1) Those who took naps from 1 to 3 pm

2) Those that got the caffeine equivalent of 2 cups of coffee at 3 pm

3) Those who took a placebo pill

The caffeinated group thought themselves the least sleepy, but the facts show that they performed the same as the placebo group, or worse, on several cognitive tests.

The group of nappers did the best, outscoring the other two groups significantly on the sensory and verbal tests.

To caffeinate or to close the eye?  When in doubt, nap it out.
