It’s Nap Time.

National Napping Day was founded by Boston University professor William Anthony and his wife Camille in 1999. Napping Day is an unofficial holiday set aside to help people adjust to Daylight Saving Time and to promote health and productivity benefits of napping. After losing an hour of sleep by "springing forward," people are more sleep-deprived and find it easier to nap.

Mid-afternoon is a time when many people experience a slump in alertness, especially after a poor nights sleep. It is felt by many that a heavy lunch causes this trough in energy. However, research show that this occurs because it is natural for us to take a mid-afternoon nap.
