* Research in the UK has shown that sleepy drivers are responsible for at least 1 in 5 motorway deaths and 1 in 10 of all road deaths. Across Europe that amounts to about 4000 fatalities a year. Sleepy drivers take no avoidance action: there is no braking or steering adjustment. Consequently sleep-related accidents are much more likely to result in death or serious injury. In fact, sleep-related accidents are three times more likely to result in serious injury or death than other road accidents. Truck drivers are at particular risk of sleep-related accidents. Driver tiredness is the most likely cause of accidental death of a truck driver and is the most likely reason for a total write-off of a truck. In the USA, 880 truck drivers were killed on the job in 1998, with over 12 deaths per 100,000 workers, making truck driving America’s most dangerous profession. How many of those might have been sleep-related? And it is not just truck drivers who are at risk. Driving on company business is probably the most dangerous thing that any employee does.? Figures from the Royal Society for the Prevention of Accidents (RoSPA) show this clearly: Annual Average Probability of Occupational Fatality: Deep Sea Fishing 1 in 750 Coal Mining 1 in 7,100 Car Driving (25,000 miles/year) 1 in 8,000 Construction 1 in 10,000 Agriculture 1 in 13,500 Service Industries 1 in 150,000? ? ? ? ? ? ? ? ? ? ? ? ? * Our bodies and brains do not work the same way at night as they do during the day. All the major organs of the body have a time of day when they function best and a time of day when they function least well. These daily highs and lows are called circadian rhythms. They are controlled by a clock in the brain, which programmes us to be ready for sleep at night, and to be active and awake during the day. It is impossible to track the progress of the body clock around its daily cycle. Instead it is usual to track the clock indirectly by measuring the daily rhythm of body temperature
