A study from China has found that higher levels of exposure to outdoor artificial light at night are significantly linked with markers of diabetes and impaired glucose homeostasis.
Previous animal studies have found that exposure to light at night may interfere with circadian rhythms and, according to new research results published in Diabetologia, people living in areas with the most exposure to light at night have a 28% higher prevalence of diabetes than those living in places with the lowest exposure. Indeed, the authors note that other research has demonstrated that chronic exposure to moderate indoor light during sleep elevates the prevalence of diabetes in older adults compared to those sleeping in a dim setting.
