Young night shift workers face a 15% higher kidney stone risk due to disrupted sleep and unhealthy habits.

A new study in Mayo Clinic Proceedings finds young night shift workers have a 15% higher risk of kidney stones, linked to disrupted circadian rhythms and lifestyle factors like low fluid intake, poor sleep, smoking, and higher BMI. Analyzing over 220,000 UK Biobank participants with a median follow-up of 13.7 years, researchers highlight that irregular work schedules contribute to metabolic and hormonal changes that increase stone formation. The findings call for workplace reforms, better hydration, and preventive health strategies, especially in healthcare, IT, and manufacturing.
