While working late nights might impress your boss, it can impair your work productivity by causing insufficient sleep. Workers who sleep less than seven hours per night have a higher rate of absenteeism. This means that you are more likely to miss time from work.
Sleep-deprived workers also have a higher rate of presenteeism. This means that you show up to work but don’t function at your best. Sleepiness will cause you to feel less motivated and unenergetic. You will have trouble concentrating and making decisions. You also will struggle to think creatively and solve problems.
This lost productivity is a huge loss for employers. A report by the RAND Corporation estimates that the U.S. loses an equivalent of about 1.23 million working days each year due to insufficient sleep.
