Despite appearances, snoring is a very serious problem, both for the person who snores and for the person who sleeps with him or her. It is well-known, for example, that through episodes of nocturnal apnoea, which are not infrequently associated with snoring, the body can become hypoxic, resulting in a variety of problems - including headaches. However, as was recently presented at the annual meeting of the Radiological Society of North America, snoring and obstructive sleep apnoea syndrome in women can also be linked to cardiac abnormalities.
