Key to snoring and sleep disordered breathing may lie in neck muscle bulk
March 19, 1999The reason why men tend to snore more and suffer more sleep disordered breathing (apnoea) than women, may lie in their neck muscles, finds research in Thorax.
Being overweight and having a thick neck are known risk factors for snoring and apnoea. Yet women tend to be fatter than men, so should be more prone to these disorders. But the reverse is true: men are up to 8 times more likely to have these disorders. The researchers assessed the soft tissue distribution, including fat, in the necks of 10 men and 10 women of average weight.
The authors suggest that during sleep muscle tone relaxes, which, combined with the greater tissue bulk, will cause the airway to collapse, provoking snoring and apnoea.
