It's a tale as old as time. Early birds are quick to rise and shine while night owls stay up late only to catch some extra z's. Our likings for early mornings or late nights aren't just coming from hard work or laziness though. A new study conduced by 23andMe suggests it can all be traced right back to our genes.
Researchers from private genetic testing company, whose name you might recognize for its at-home kits which sample a person's saliva to reveal ancestry, used the organization's genetic database to analyze the DNA of over 89,000 people. Participants of the study took part in an online survey consisting of two questions in an attempt to count as "morning people" or "night people". From the profiles, researches narrowed in various factors as to what most likely contributes to a morning person. Their findings revealed that it takes a certain type of person and gene to be an "early bird":
The Female Gene
Morning people tend to be women. The study revealed that 48 percent of women were morning people. On the other hand nearly 40 percent of males preferred getting up early.
The Age Factor
Only 24 percent of people surveyed who preferred mornings were under the age of 30. On the opposite end, 63 percent of people over 60 liked being early risers.
The Night's Rest Factor
Good sleepers and people who didn't suffer from insomnia were good to go in the mornings.
The Well Rested Kinds of People
No surprise the study revealed that people who liked waking up early were those that had been well rested and had less than eight hours of sleep each night.
The Goldilocks Factor
People with extreme BMIs (i.e. overweight and underweight people) were more likely to be night owls.
While these findings are interesting, take these revelations with a grain of salt. The study was limited to people of European descent, which means that the findings can't be accurately applied to other groups. While you won't to point to it for solid proof as to why you need to sleep in, for the time bringing night owls can blame their genes for struggling to wake up in the morning.
