How Night Shift Work Is Shortening Lives
June 8, 2025 · Frisian News
New research shows that workers on night shifts face higher risks of heart disease, cancer, and early death. The damage comes from disrupting the body's natural rhythm, not just from fatigue.
A factory worker in Bremen clocked out at 6 a.m. last week after another twelve-hour night shift. His body has not seen daylight during work hours in three years. Research has found that long-term permanent night shift work reduces life expectancy. The damage runs deeper than simple tiredness.
Night work breaks the circadian rhythm, the internal clock that controls hormone release, digestion, and immune function. When workers sleep during the day and labor at night, their bodies produce less melatonin and more cortisol. Blood pressure stays elevated. Inflammation increases. The pancreas struggles to regulate blood sugar. None of this heals on weekends or days off. The clock never truly resets.
Companies push night shifts because they cost less than hiring extra day workers or investing in automation. Hospitals, factories, and logistics firms have built entire business models around cheap night labor. Regulators tolerate the practice because they view it as normal. Workers accept it because they need the money and because refusing shifts means losing the job entirely.
The health toll spreads unevenly. Older workers suffer more. Women on night shifts face elevated cancer rates. Workers in low-income countries, where labor protections vanish, bear the worst damage. Yet governments rarely restrict night work or require higher wages for it. The European Union set weak guidelines. Most nations set none. The cost of keeping people awake at the wrong hours lands on workers' bodies, not on company balance sheets.
Better solutions exist. Some countries have moved toward rotating shifts that respect the body's adjustment capacity. Others have restricted permanent night shifts for older workers. A few have simply hired more staff and run true twenty-four-hour operations without destroying individuals. These changes cost money upfront. Workers live longer. That trade does not suit companies hunting quarterly profits.
