A group of scientists from the University of Exeter in the UK have found that the predisposition to insomnia is in the genes. Researchers have discovered 47 sections of DNA that determine how easily a person falls asleep.

Experts analyzed the DNA of more than 85 thousand people, finding about 50 such areas that affect a person's ability to quickly fall into a state of sleep. Moreover, 36 segments have never been identified before. This information can be useful in the development of new treatments for insomnia. The study was led by Dr. Samuel Jones, Research Fellow at the University of Britain College of Medicine.
Excessive sleep improves health and well-being, but scientists find it difficult to explain the mechanism that influences this process. The process of changing the latter is associated with several diseases, including a decrease in the quantity and quality of rest time. Diabetes mellitus and obesity are particularly negative, and the same applies to mental disorders, noted Dr. Andrew Wood, co-author of the study.
