Genetics determines that people wake up early and early, which will also create a welfare greater and reduce the risk of schizophrenia and depression, according to a study published in Nature magazine.
The study is conducted by the University of Exeter (United R.) and the Massachusetts General Hospital (USA), which explores the functioning of our biological clock from a broad database of genetic analysis.
Experts associated mental health and illnesses with morning quality, including those that do not appear, needs, diabetes, or obesity, as they have previously considered.
The study emphasizes the role of the retina of the eye in support of the body's control over time and the genome-wide range of delay between 24 and 351.
"This paper explains some of the genes to study in more detail so that people can understand different biological clocks," said Mike Weedon, Exeter University School of Medicine.
The large number of people involved in this research, "has given us the clearest evidence, has already been achieved," "night owls have a greater risk of mental illness."
In total, 250,000 individual genomes were studied in a US database. and 450,000 in the United Kingdom, they were asked to "go in the morning" or "night" people.
They then sought to identify the genes that were in common and how they were causing their performance, compared to 85,000 compared to the data of individual Biobank, to create a bracelet activity for the subjectivity of the respondents.
The genetic variants indicated may take 25 minutes to wake up at an hourly natural time, for example, from 8:00 a.m. to 08:30 p.m.
Genomic regions have identified our body clocks, known as "circadian rhythms," which have also detected the presence of genes in the brain and retina.
The biological clock cycle is slightly longer than the 24-hour diary, and consequently the connections of the ocular tissues reveal what the brain detects as a light "restart" the clock daily and synchronize it with the daily cycle.
Our biological clock works, they add, genes and our lifestyle, such as diet, artificial light exposure and our work and activities.
The Nobel Prize in Medicine recalls, in 2017, that three scientists find molecular mechanisms that control the rhythmic rhythm of American scientists, "biological internal clock", adapting plants, animals and humans to Earth's rotation.
"Our work is partly due to the causes that people have begun early and others are revealed at night, because of the differences between our brains that respond to external light signals and the normal functioning of our watches," says Samuel E. Jones University of Exeter.
"Small differences," he said, "the ability of biological clocks to" effectively control the effects "could" change the risks associated with diseases and mental disorders. "
