Taking an afternoon nap can help you from feeling drowsy and increase your afternoon productivity. Many benefits of naps exist to include a decrease of heart disease related death by almost 40% and an increase in work productivity. This can assist companies from losing some of the $18 billion annual dollars lost due to drowsy workers. The best time for a nap is around 1:00pm and 3:00pm for 20 minutes to promote alertness and motor learning.
By the way, you don’t even have to actually “sleep” … just closing your eyes, listening to your favorite music or meditating … or day dreaming … has many positive benefits as well.
