What can disrupt the normal sleep-wake patterns leading to fatigue?

Shift working can significantly disrupt normal sleep-wake patterns because it requires individuals to alter their sleep schedules to accommodate hours that are different from the traditional day shift. This alteration can lead to misaligned circadian rhythms, which are the body’s internal clocks regulating sleep, alertness, and various bodily functions.

When working shifts, especially night shifts, individuals may struggle to obtain quality sleep during daylight hours when their bodies are naturally predisposed to be awake. This disruption can result in chronic fatigue and other negative health impacts, including decreased cognitive function and mood disturbances. In contrast, regular exercise, healthy eating, and consistent bedtimes are beneficial practices that support good sleep hygiene and can help maintain healthy sleep patterns.
