The Canadian study, carried out on rats and published in science journal Experimental Physiology, designed to investigate why men suffer from sleep-disordered breathing more than women.
The findings suggest that a stressful experience in early life, such as separation from the mother, can disrupt the development of male babies’ hormone regulation systems.
One potential consequence of this disruption is respiratory problems in adulthood, including snoring.
In the study, carried out on male rats, those removed from their mothers in early life showed more breathing difficulties when the oxygen level was reduced, simulating the relaxation of the respiratory system which takes place during sleep, than those left undisturbed with their mothers.
