Underestimating the societal costs of impaired alertness: safety, health and productivity risks.

Modern society now operates on a 24/7 global basis, with around-the-clock requirements that often ignore sleep, circadian rhythms, irregular work schedules and geographical time zones. Despite overwhelming evidence, there is gross underestimation and very little acknowledgement of the risks and costs related to sleep loss, circadian disruption, sleep disorders, reduced alertness and performance. Understanding the specific factors that impede our progress in addressing impaired alertness as an important societal issue could lead to raised awareness of the risks and costs and subsequent implementation of change. Effecting change requires an understanding of the complexity of the issue and a multidimensional approach. Real world data and outcomes are required to determine the exact extent of the health and safety risks related to impaired alertness. More public awareness of the potential hazards of impaired alertness is needed among the general population to increase societal knowledge and appreciation. Physicians need to be educated about the importance of detecting impaired alertness in their patients and should be aware of the range of actions needed to help these individuals so that they do not cause harm to themselves or others. A comprehensive approach using scientifically based alertness management principles and practices offers society an opportunity to operate 24/7 while reducing the risks and costs associated with impaired alertness.
