Shift work, especially night shift work, is associated with a variety of long-term health problems that can shorten lifespan. Research suggests that shift workers are at higher risk of cardiovascular disease, metabolic disorders such as diabetes, and certain cancers due to disrupted circadian rhythms and lack of sleep. There are no exact figures for how many years shift work reduces lifespan, but studies have shown that people who work night shifts for more than 10 years may experience a slight decrease in life expectancy. Life expectancy in severe cases is estimated at 5-10 years. The extent of the impact depends on factors such as the duration of exposure, the individual’s health, and lifestyle choices.
