Scientists analyzed data from 52?027 people aged 60 years and older. 60% of them were women. Experts have compared how often subjects used the prescriptions for sleeping pills, with the satellite maps of electric lighting.

As a result, the researchers found a link between the intensity of artificial illumination and insomnia in humans. It turned out that not only often, but in higher doses drugs for insomnia was used by the people living in the areas with the most intense artificial light.
