Good info. I learned this years ago from my great-grandmother. She took a nap every afternoon for 20 to 25 minutes. Now, living in Chengdu, office workers here are encouraged to nap after lunch time, around 2. At my wife's office, there is a chime followed by soft music twice a day, reminding workers its time for a break to do eye exercise, something they teach or at least used to teach in Chinese elementary school. Many offices in Chengdu also have a tea break around 4 ;)
