Insomnia and napping
Napping for 20-40 minutes before 3pm is ok and can help with productivity. Napping any longer or later in the day may intefere with regular sleep cycles. Also napping should not be used instead of sleeping about 7 1/2-8 hours per night but rather as an adjunct to overall health and well-being. Naps have been shown to help reduce heart disease and increase cognitive brain function.
