A recent study based on genetic structure found that our genes might tell us if we are early birds or night owls.
Scientists claim that 15 regions of the human genome are related with the fact that we are or are not a morning person. Also, it was shown that people who get up early in the morning are healthier than those who don’t.
Moreover, based on their information, so-called night owls are prone to depressive episodes and obesity. However, scientists are still trying to find pertinent evidence in order to support their claim. The researchers analyzed the DNA of 89, 283 individuals.
They were questioned about their sleep hours and their lifestyle preferences. The main author of the study declared that the research discovered more on an individual’s preference toward early rising. The team was also able to find how the genetic structure is associated with ‘morningness’.
The data showed that most of the participants in the study did not think of themselves as being early birds. Nonetheless, those who presented the morning DNA features were women or adults over 60. Also, the study concluded with an insight into who might have this type of genes. In addition, new genes that had never been associated with sleep behavior before are now revealed.
Researcher David Hinds says that:
“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”.
According to their information, morning people have a lower BMI and they are less likely to experience depression. Apparently, the main factor that sets our tendency for morning is the circadian rhythm.
As scientists declare, circadian rhythms are a universal characteristic of living organisms. They can affect almost every biological process. The phases of circadian rhythms determines our innate tendency for mornings or evenings.
The fact that our genes might tell us if we are early birds or night owls can become a real breakthrough in medicine. Doctors would be able to find treatments and suggest more productive schedules for those who have trouble sleeping.
