Snoring and other types of "sleep disordered breathing," as it is known, can deprive the body of enough oxygen for hours at a time. And scientists now believe having low blood oxygen levels can trigger the development of cancerous tumors, by promoting the growth of the vessels that feed them.
Researchers in the US looked at cancer rates in more than 1,500 people, in a study of sleep problems that has been going for 22 years. They found those with severe sleep disordered breathing (SDB) were 4.8 times more likely to develop cancer than those who had no such problems.
This is good news for two reasons. First, it's nature's way of eliminating annoying people. Second, it introduces yet another acronym for hypochondriacs to call their doctors about. SDB. Sound serious.
