Study Further:

Researchers, in affiliation with 23andMe, Inc. recently worked on the DNA of 89,283 individuals, and found that genes could show some specific variations more frequently in the people, who self-identify themselves as early risers or morning people. They found 15 different spots in the genetic makeup that can vary between morning people and self-reported evening people. Seven of those variations were found near genes that are involved in controlling a person’s daily cycle, known as circadian rhythm.

Study also showed that many people, i.e. more than 50% consider themselves as night people. Adults and females represent more numbers as morning people, i.e. in the study 39.7% morning people were males and 48.4% were females. If a father is a morning person, his son has 1.9 times higher chances of becoming a morning person and his daughter has 2.4 times higher chances of becoming a morning person. Moreover, morning people suffer less from sleep apnea or insomnia as compared to night people; though, genes or genetic variations may not have any role in this aspect. On a further note, night people have more chances of getting depression as well as other health issues such as obesity.

“With the information we have, we can uncover the genetics behind a variety of conditions and diseases, and hopefully reach a better understanding of how we differ from one another,” noted 23andme senior researcher David Hinds in a press statement.
