A study published earlier this week in Hypertension, a journal of the American Heart Association, found that men were 80% more likely to develop high blood pressure if they did not receive enough sleep or if their sleep was interrupted. Researchers studied almost 800 men who were given at-home sleep tests that looked at their sleep patterns and measured their non-rapid eye movement sleep, also known as “slow wave sleep,” or deep sleep.

The study revealed that poor quality sleep due to due to sleep apnea, medications, or other health issues, puts individuals at a significantly increased risk of developing high blood pressure. Experts often refer to slow wave sleep as the time when the body is restoring its energy reserves; blood pressure goes down, breathing slows and the heart rate drops. This research suggests that if blood pressure doesn’t drop sufficiently while sleeping, it may damage blood vessels. Too little deep sleep may also cause parts of the brain that control the release of a number of hormones and other substances related to maintaining proper blood pressure to work less efficiently.

According to iData Research, the therapeutic sleep apnea market will exceed $1.5 billion by 2017. An increasing awareness of the symptoms, diagnosis, treatment and co-morbidities of sleep apnea will lead to growth in the overall sleep therapeutics market.
