Your GENES are to blame if you’re not a morning person! 

According to a new study done at the University of Leicester, your biological clock is genetic. 

The study examined the sleep patterns of fruit flies, as they have a similar ‘genetic clock’ to human beings. 

Post examination, researchers were able to identify around 80 variants playing a role in our sleep and wake preferences. 

Researchers came to the conclusion that the entire genetic makeup of a fly that is active in the morning was different to the genes of a fly that was more active in the evening. 

“Looking at the gene expression was only part of our research. An obvious question is what causes the different expression in the larks [early risers] and owls [late nighters]. This difference is largely due to genetic variations in their DNA sequences — different gene versions that are present in larks and owls.” Dr. Eran Tauber, one of the study’s coauthors, said. 

“The end point might be similar, but the different molecular routes result in a different journey time.”

The researchers argue, given the findings, the nine-to-five structure is likely inefficient for many.
