Research has long linked life expectancy with hours slept. Now new research published in "Thrombosis and Vascular Biology" based on research in South Korea finds that 7 hours sleep is the optimum for good cardiovascular health (much the same as the previous more general studies relating to life expectancy). This latest study, which is based on 29,000 people, concludes that women are more at risk of coronary lesions than men as a result of poor sleep. Compared with 7 hours' sleep, men and women, who slept for 9 or more hours, were found to have 70% more calcium in their coronary arteries and those who slept for under 5 hours had 50% more.Billy Bunter did not look after his cardiovascular health.

The theory propounded is that the underlying cause of damage is cortisol, the stress hormone. Chan-Won Kim, one of the researchers is quoted as saying, "Inadequate sleep is a common problem and a likely source of poor health, including visible signs of disease such as heart attack."
Readers will not have overlooked that L-arginine, which produces ADNO, boosts quality of sleep. ADNO diminishes naturally during sleep (hence the number of heart attacks at night) and so there is a double plus: first, you are more likely to have 7 hours of nourishing sleep and, secondly, ADNO relaxes and cleanses the arteries.
