Shift work can disrupt the body's circadian rhythm, which is the internal clock that regulates sleep-wake cycles and other physiological processes. Disruption in circadian rhythm can lead to sleep disorders, fatigue, and a range of health issues, including metabolic disorders, cardiovascular diseases, and mental health problems. Furthermore, shift workers often have unhealthy lifestyles, characterized by poor diet and insufficient exercise, which can exacerbate these health risks.
