Night shifts refer to work hours that take place during the night, typically starting in the late evening and ending in the early morning. Many industries, such as healthcare, manufacturing, and hospitality, require employees to work at night to ensure continuous operations. Night shifts can vary in length, often lasting from 8 to 12 hours. Working night shifts can impact a person's sleep patterns and overall health. Employees may experience fatigue, difficulty concentrating, and changes in mood due to the disruption of their natural circadian rhythms. Employers often implement strategies to support night shift workers, such as providing adequate breaks and promoting healthy sleep habits.
