During most times of the day or night, overexertion involving outside sources is the most common cause of workplace injuries or illnesses for which people miss work to recuperate. During the early morning hours of 4:01 to 8:00, falls to the same level were also a leading cause of workplace injuries or illnesses.
During the nighttime hours of midnight to 8:00 a.m., 16 percent of workplace injuries or illnesses occurred. Intentional injury by a person makes up 4 percent of the injuries or illnesses between the hours of midnight and 4:00 a.m.
