Night Time Light Could Be Linked To Sleep Deprivation

Results show that increasing nighttime levels of artificial, outdoor light exposure, stratified by quartile, were associated with an increased prevalence of hypnotic prescriptions and daily dose intake. Furthermore, older adults exposed to higher levels of artificial, outdoor light at night were more likely to use hypnotic drugs for longer periods or higher daily dosages. “This study observed a significant association between the intensity of outdoor, artificial, nighttime lighting and the prevalence of insomnia as indicated by hypnotic agent prescriptions

for older adults in South Korea,” said Kyoungbok Min, PhD, an associate professor in the Department of Occupational and Environmental Medicine at Seoul National University College of Medicine in South Korea. “Our results are supportive data that outdoor, artificial, nighttime light could be linked to sleep deprivation among those while inside the house.” The study results are published in the Nov. 15 issue of the Journal of Clinical Sleep Medicine. bmd
