Scientists believe that ultraviolet rays generally protect the children's nervous system from many negative factors, according to Pannochka, an online publication for girls and women from 14 to 35 years old.. net Researchers' conclusions are based on a map of the United States, as well as nine other countries shaded according to the number of cases of ADHD per person.. Scientists in the course of the analysis found out how many sunny days there are in these areas during the year.

The relationship between the development of ADHD in children and the number of sunny days remained significant even after controlling for other factors.. Scientists tested their theory on children with autism or depressive disorders. However, the amount of sunlight in this case did not matter.

The author of the study, Dr. Martin Arns, believes that the beneficial effect of the sun on the frequency of occurrence of ADHD in children may be due to the activity of the biological clock..
