Waking up or waking up early may be due to genetic factors

Paris- NEW YORK (Reuters Health) – The ability to wake up early or not is due to genes that affect more than 350 of them on a biological clock, according to a study published in the NatureCommunity journal.

"Our study shows that love or early awakening is partly due to genetic factors," said Michael Waddon of Exeter University and co-author of the study.

This study allows us to know more about the "mechanisms governing the biological clock".

The biological clock regulates the main functions of the body, from sleep to the immune system, through body heat and hunger.

Many researches have shown a link between irregularity and certain diseases such as heart disease, diabetes and Alzheimer's disease.

The researchers analyzed DNA data from about 700,000 people from databases comparing the genes of people claiming to wake up early or not.

They then studied the data of more than 85,000 people who recorded their sleep patterns with the help of a bracelet.

The researchers identified 327 genes affecting sleep, of which only 24 were known.

These genes affect the normal waking hours but do not affect the quality or duration of sleep.

The researchers also noted a link between recent awakening for genetic reasons and an increased risk of schizophrenia or depression, but they stressed the need for further research.

Getting up early can be synonymous with well-being.
But the study did not decide whether this was due to genetic causes or simply because lifestyles were more adaptable to early awakening.

However, genes are not the only ones responsible for the difficulty of waking up, but the power and exposure to artificial light, work and activities also play a role.
