'>1. Getting too little sleep for several nights in a row disrupts hundreds of genes that are essential for good health, including those linked to stress and fighting disease. Tests on people who slept less than six hours a night for a week revealed substantial changes in the activity of genes that govern the immune system, metabolism, sleep and wake cycles, and the body’s response to stress, suggesting that poor sleep could have a broad impact on long¬term wellbeing.2. The changes, which affected more than 700 genes, may shed light on the biological mechanisms that raise the risk of a host of ailments, including heart disease, diabetes, obesity, stress and depression, in people who get too little sleep. ’’The surprise for us was that a relatively modest difference in sleep duration leads to these kinds of changes," said Professor Dijk, director of the Surrey Sleep Research Centre at Surrey University, who led the study. “It’s an indication that sleep disruption or sleep restriction is doing more than just making people tired.”3. Previous studies have suggested that people who sleep less than five hours a night have a 15% greater risk of death from all causes than people of the same age who get a good night’s sleep. In one survey of workers in Britain more than 5% claimed to sleep no more than five hours a night. Another survey published in the US in 2010 found that nearly 30% of people claimed to sleep no more than six hours a night.4. Professor Dijk’s team asked 14 men and 12 women, all healthy and aged between 23 and 31 years, to live under laboratory conditions at the sleep centre for 12 days. Each volunteer visited the centre on two separate occasions. During one visit, they spent 10 hours a
