So, what is a coffee nap?
A coffee nap is when you drink a cup of coffee, and then take a 20-minute nap.
Most people would think that this would never work since we drink coffee to stay awake.
So how could we sleep to take a nap after having a cuppa caffeine jolt?
It turns out that rather than keep us from napping, coffee and a nap could be the recipe for an alert afternoon.
