Two more Sleeps
It's that time of year when children speak about how many more sleeps it is until Christmas Day. The Economist this week raises the link between sleep and well being. It quotes William Dement, founder and director of the Stanford University Sleep Research Centre, who claims that people on average now sleep one-and-a-half hours a night less than they did a century ago. He and others claim this has a cost to health and safety. He quotes recent disasters which have been associated with people in control being sleep deprived.
The optimum amount of sleep was studied by Daniel Kripke of the University of California at San Diego (see FinDem News 16 February 2002). He found people having seven hours sleep having best survival stats while for those having longer hours of sleep, survival was shorter (but this is just an association and other factors could explain the difference).
