Sleeping at work is generally considered lazy. However, a commentator in the New York Times quoted experts as saying that a nap can improve people's attention, concentration, and productivity, and advertised the idea of ​​“taking a nap in working hours without feeling sorry for anyone!â€. This article entitled “Take Naps at Work. Apologize to No One†(without apologizing at work) was published by Tim Herrera, a commentator for the New York Times. For example, the founder of the scientific research center Bersin by Deloitte pointed out that “fatigue can affect the productivity of workers,†and it is not known that the right sleep has an advantage in improving productivity. Employees should report this appeal to their superiors. The article also mentioned that a study by Dr. Sara Mednick of the University of California, California, found that among the four smart test tests performed in a day, the scores of those who did not sleep all day would gradually decrease over time. However, if the participants were given 30 minutes of sleep time during each experiment, the overall score was greatly improved; if the participants were allowed to sleep for 60 minutes in each test, they could also return to the score at the first test. Research suggests that quality daytime sleep can achieve the same benefits as nighttime sleep. Dr. Sara Mednick also believes that a nap of 20 minutes to 60 minutes will allow the brain to rest and improve memory and learning. And sleep more than 60 minutes, but also can let people enter the "rapid eye movement sleep" (rapid eye movement (REM), also known as desynchronization sleep, this period of rapid eyeball rotation, the brain is very active, dreaming All of them are in this period.) State will give people more creative inspiration after a break. However, the article quoted the experiments done by the late American writer Jerry Siegel, which showed that humans only need 7-8 hours of sleep each day. People in the city feel tired during the day because of poor quality sleep at night. If you sleep well at night, you may not need to take a nap during the day. In the end, the article author Tim Herrera also provided tips for several naps: 1. Find a quiet environment with no one around so that you will not be disturbed. 2, try to make the environment dark, or wear eye masks. Also wear earplugs to reduce noise. 3, first set the sleep time as 20 minutes, adjust the time later. It is important to note that if you sleep longer than you need, you will feel more powerless than you did not sleep.
