Insomnia has been linked to several genes

Insomnia is a disorder than many of us have had to go through at some point in our lives. But only 10% of the entire country has been reported to have chronic insomnia. A group of researchers found seven different genes that coded for insomnia, proving it is a genetic disorder that is fairly common. The researchers also found that the genes that code for insomnia also link to many other genetics disorders such as, restless leg syndrome, anxiety, depression, and neuroticism. This article was interesting to read because it has always been known that disorders like anxiety and depression were commonly associated with insomnia. Not everyone has been affected by insomnia directly but almost everyone has known someone who suffered from insomnia.
