The article discusses the effect of biological rhythms on human performance. According to the author, the so-called timekeeping system or biological clock enables an organism to anticipate and prepare for the changes in the physical environment linked to day and night. It also provides internal temporal organization, as well as ensure that internal changes take place. Disturbances in the normal circadian rhythm can have serious health consequences, including mental and physical disorders which may affect safety, performance and productivity.
