This weekend the annual conference began in the United StatesSLEEP 2009(dream, in English), which in this edition brings together more than 6,000 experts insleep medicine. Among the studies that the researchers will present these days include some as interesting as the one recently carried out by the University of Pennsylvania, which reveals thatwatching television before going to sleep often leads to sleep debt, which increase the risk of falling ill.
Spending too much time in front of a console is also associated with a sleep deficit. According to Amanda Woolems, from the University of Arkansas, the great “gamers”, that is, those who spend more than seven hours a week with video games and consider themselves “addicted” to this form of leisure, sleep less than is recommended in the working days and sufferdrowsinessduring the day. For his part, the Australian Siobhan Banks today presents the results of an investigation that shows thatpeople who sleep little have their appetite reducedand food consumption but, paradoxically, alsotend to gain weight.
However, it is also not advisable to sleep excessively. Spending more than 8 hours in bed increases the risk of diabetes, according to another study conducted in New York using data from nearly 30,000 subjects between the ages of 18 and 85. Regarding the relationship between exercise and rest, Arn Eliasson of Walter Reed Army Medical Center has just debunked the myth that increasing physical activity improves the quality and duration of sleep. In fact, his experiments show just the opposite trend.
