DNA Plays A Part In Predicting Whether You're A Morning Person Or A Night Owl

Ever wondered what makes you a morning person or a night owl? According to a latest study conducted by 23andMe, a known genetics company, your DNA plays a part in it all.

The study, which was published recently in the Nature Communications journal, showed that there are certain genetic variants common among morning persons. In a report by Tech Times, 23andMe's team of researchers led by David Hinds, analyzed variations in genes, allowing them to associate specific genes with specific traits.  

There were 135,000 participants who submitted DNA samples. They also answered two online questionnaires that aim to figure out their waking time preference.

The result of the study showed there are 15 genes linked to being a morning person. Seven of these genes are found close to that associated with the circadian rhythm, or the body's internal clock. A certain number of these genes are found closely near those that sense light coming from the eyes.

Based on gender, there are more women who said that they are morning persons as compared to men. Based on age, those who are 60 years old and above prefer mornings than those individuals 30 years old and below.

According to Gen News, Youna Hu, a former 23andMe data sciences engineer who was with 23andMe when the study was conducted, "We set out to discover more about an individual's preference toward early rising and were able to identify the genetic associations with 'morningness' as well as ties to lifestyle patterns and other traits."

Hu also gave high regard to the power of the 23andMe database. She said that the database can produce a variety of genetic insights and how the behavior and environment affect genetic factors.

The study can greatly help medical practitioners understand the manner by which the he circadian rhythm works. It can then use the information to look into sleeping disorders and the lifestyle of healthy individuals.
