The intermittent hypoxia that often occurs with sleep apnea, promotes cancer by encouraging blood vessel growth inside tumors.
A new sleep apnea study has found that snoring promotes cancer development because it limits oxygen intake.
Numerous studies have linked bad sleep to poor cancer outcomes, and this latest study reveals that hypoxia may be the reason why. Researchers in Spain explain that hypoxia, which is just one of the consequences of sleep apnea, happens when body tissues or organs don’t get enough oxygen.
Intermittent hypoxia, which is a common side effect of obstructive apnea, apparently worsens cancer development by promoting blood vessel growth within tumors.
