Got 14 Dollars? how about buying 20min. of quality sleep.
Metronaps opened its doors in New York in the Empire State Building and offers mid day sleep in specially designed pods.
Metronaps states research on its site that highlights the benefits of midday rest and power naps. For instance: "midday naps may protect brain circuits from overuse until those neurons can consolidate what's been learned about a procedure." Or "evidence is mounting that sleep - even a nap - appears to enhance information processing and learning."
