Is a good night's sleep crucial for your health?
Date:10/22/2007

In spring 2005 a large European research and training network was established to investigate the causes and implications of poor sleep from a medical as well as from a social point of view.

They are researching the role of sleep in the quality of life; in mood disorders, and how it can affect performance, accident rates, and cardiovascular diseases. Animal models complement the project aiming to understand the basic mechanisms underlying sleep regulation and thereby provide recommendations for the development of new hypnotics.

Although the work is only half way through, interesting results have already emerged, and the project has now been nominated as one of the success stories among EU-funded projects.

They found that following sleep restriction to 4 hours per night, an individuals ability to perform complex tasks gradually decreased during the five days. Several changes in their imm
