A new study has shed light on the relationship between sleep, breathing, snoring and brain function, it has claimed.
Due to be published in the first November issue of the American Journal of Respiratory and Critical Care, the study measured the degree to which the brain's blood remains oxygenated during sleep.
The researchers used technology called near infrared spectroscopy - which penetrates the skull using high-powered light beams to see how much oxygen the blood contains - to assess how much blood was in different areas of the skulls of the participants, who were between the ages of seven and 13.
Blood pressure during sleep was also measured.
Snoring children were found to have lower "regional cerebral oxygen concentration" than those who did not snore.
However, it was found that those with the disorder sleep apnoea have higher regional cerebral oxygen concentration than those with just snoring.
"Children with sleep apnea have higher blood pressure compared to children with snoring. This may explain why paradoxically we find higher oxygen levels in children with obstructive sleep apnoea," commented Dr Raouf Amin from US institution Cincinnati Children's Hospital Medical Centre.
