It is quite common to call ‘night owls’ people that have trouble going to sleep at night and waking up in the morning. However, a new study claims to have found a reason behind this habit, namely, a gene mutation.
The research team found that the so-called night owls could be carrying a specific gene variant. This could lead to a nighttime sleep delay of even up to 2 to 2.5 hours when compared to people that do no have this gene.
According to the study, night owls are often diagnosed with DSPD or “delayed sleep phase disorder”. This means that the person’s circadian rhythm comes with a delay when compared to the typical day/night cycle.
The development of the DSPD could be tied in with specific mutations. More exactly, the study linked it to CRY1 gene changes. Reportedly, almost 10 percent of the population could be affected by DSPD, at least according to the clinical studies. People with such an affection find it hard to fall asleep at night. In some cases, they may be actually unable to do so. Instead, a good night’s sleep could just be fractured into some long naps.
Night Owls May Manage To Control Their DSPD
The lack of sleep can have quite serious consequences on the health. It may also lead to social complications as DSPD sufferers could be finding it hard to adapt to such expectations or mule around morning schedules.
The research team published its study results in the Cell journal. In the paper, they revealed that they found the gene mutations while studying the skin cells of people with DSPD. Also, the team pointed out the following.
“An external cycle and good sleep hygiene can help force a slow-running clock to accommodate a 24-hour day.”
This is because the circadian clock can react to external environmental factors. As such, it is allegedly possible to manage the effects of this gene mutation on sleep.
