Working a rotating night shift roster is linked to a decreased likelihood of healthy aging, according to a study of female nurses in the US. The nurses were followed up 24 years after they recorded their night shift work to see if there was any link to changes in their health over time. The study found the odds of healthy aging decrease with increased time spent working rotating night shifts, with the worse outcomes among those who worked nights for 10 or more years.
