A study shows certain chromosomes in people of European descent are more likely to suffer from insomnia, reports my body + soul.
Struggling to go to sleep is linked to specific mutations on certain chromosomes, according to a new study. The research published in the journal Molecular Psychiatry, found a genetic link between a lack of shut eye, type 2 diabetes and depression.
Researchers from the University of California, San Diego, examined two study groups of soldiers and assessed their genes and sleep states to see if there was a connection between insomnia and genes. The soldiers were selected for the investigation due to previous research that suggested up to 50 per cent of those in the military struggle to sleep.
The first group of participants included 33, 088 soldiers at the beginning of their basic training, who gave blood samples for DNA analysis, completed questionnaires, and were interviewed on their sleep habits.
