Sleep deprivation 'can cause strokes'

  • Comment

Stroke or heart disease susceptibility is dependant on how much you sleep you get, a new study has suggested.

A Warwick Medical School study has discovered that prolonged sleep deprivation can have a seriously adverse effect on cardiac health.

The research team linked a lack of sleep to strokes, heart attacks and cardiovascular disorders which can often cause early death.

Professor Cappuccio and co-author Dr Michelle Miller examined evidence from more than 470,000 participants across eight countries, including Japan, the US, Sweden and the UK.

Professor Francesco Cappuccio said: “If you sleep less than six hours per night and have disturbed sleep you stand a 48% greater chance of developing or dying from heart disease and a 15% greater chance of developing or dying from a stroke.

“The trend for late nights and early mornings is actually a ticking time bomb for our health so you need to act now to reduce your risk of developing these life-threatening conditions.”

Dr Miller added chronic short sleep produces hormones and chemicals in the body, which increases the risk of developing heart disease and strokes, plus other conditions such as high blood pressure and cholesterol, diabetes and obesity.
