Being on-call for work, where you must remain reachable and ready to act at short notice, often disrupts sleep. Research shows that merely knowing you might be called in is enough to cause sleep disturbances, even if the call never comes. This uncertainty creates anxiety, leading to poor sleep quality. Sleep is crucial for cognitive function, emotional regulation, and physical health, yet on-call workers frequently sacrifice it due to irregular schedules and work demands. Employers can mitigate these effects by designing flexible rosters that allow adequate recovery time between shifts. Individuals can also prioritize sleep hygiene by maintaining a cool, dark bedroom environment and avoiding stimulants before bed. The article emphasizes the need for better workplace practices to support on-call workers' health and well-being, highlighting the broader implications of poor sleep on daily life and long-term health outcomes.
