Most of us have a downtime in our day approximately 7 to 8 hours after we awaken so that means between 2 and 4 pm we may not be at our mental best. The benefits of an afternoon nap are well known with 10 to 20 minutes being the most ideal. We arise from the nap with increased mental sharpness. You can increase this mental boost even greater by having a pre-nap cup of coffee. The caffeine will kick in just about the time you get up and perhaps your thinking will be even sharper. It seems there is another benefit to having that extra cup of coffee!
