The nearly 18,000 law enforcement agencies in the United States are active every minute of every day. This means that law enforcement personnel need to be in top conditions 24 hours a day, 365 days a year. Shift work is a necessary and integral part of the law enforcement profession that affects all the nearly 800,000 U.S. police professionals at some point during their careers to ensure that policing services can be provided around the clock. This reality has a direct impact on the wellness of law enforcement officers. Chronic fatigue and other illnesses caused by irregular work schedules have long been a source of concern for law enforcement officers. The National Institute for Occupational Safety and Health (NIOSH) recently discussed the Buffalo Cardio-Metabolic Occupational Police Stress (BCOPS) study, which followed hundreds of public safety officers between 2004 and 2020, tracking their work schedules and health over the course of the project.
