Biologist Pere León Warns Night Shifts Cut Lifespan by Six Years

Research by biologist Pere León shows that employees who frequently switch between day and night shifts lose about six years of life expectancy compared to those with stable schedules. The study links irregular sleep cycles to increased risks of cardiovascular disease, metabolic disorders, and chronic fatigue.

Professions such as pilots and flight attendants face additional hazards from radiation exposure and irregular flight hours. Experts recommend maintaining consistent shift patterns and prioritising sleep hygiene to mitigate these risks.
