Insomnia and Blood Pressure
Friday, July 24, 2009

Insomniacs who sleep fewer than five hours a night are five times more likely to suffer hypertension than people who sleep well, according to a study that highlights the growing concerns over links between sleep problems and serious illness.

People who get less than five hours of sleep a night are five times more likely to develop high blood pressure than sound sleepers who get enough rest.

The link between sleep apnea and hypertension is well established. But a study by Penn State researchers is one of the first to find that insomnia also raises the risk for high blood pressure.

The study involved 1,700 randomly selected adults who agreed to spend a night in a sleep laboratory.

The sleep assessment revealed that people who slept less than five hours a night and had insomnia had the highest risk of hypertension.

Those who slept five to six hours a night and had insomnia had an increase in high blood pressure risk, compared to normal sleepers without insomnia or poor sleep.

Researchers continue to uncover links between a lack of sleep and a wide range of medical conditions, including obesity in adults and children, and related diseases like heart disease and diabetes.
