Babies sleep up to eighteen hours a day. Mrs. Thatcher and Napoleon both said they only needed to sleep three or four hours a night. Sleep—No one can live without it. But how much do we really need? 

Research by the National Sleep Foundation in Washington says that we all need eight hours' sleep every night. Scientists have found that people who sleep for less than six and a half hours a night are more often ill than people who sleep for eight hours. Going without sleep also increases the chance of serious illness. Workaholics who sleep for less than five hours often die young, and do less well at work. 

The scientists found that, on average(平均起来), adults sleep for seven hours a night, with 32% sleeping less than six hours. It also says that the idea that we need less sleep when we get older is completely untrue. "People have no idea how important sleep is to their lives," Dr. Thomas Roth, director of the Foundation says. "Good health needs good sleep."

"But not too much of it," says Professor Jim Home of Loughborough University. "Sleep is like food and drink," he believes, "You would always like to have a little bit more, but that doesn't mean you need it." Professor Home studied a group of people who could spend as many hours as they wanted in bed; after sleeping ten hours, they didn't find that they could get up easily either. And people who sleep for more than nine hours a night die younger than people who usually sleep for seven or eight!

Nigeria is a hot and dry country in Africa where electricity is not available to many homes. Most people grow and sell their own fruit and vegetables. Keeping them fresh in the hot place is a real challenge. Without a fridge, most fresh food goes bad in a couple of days. Throwing away the food means losing money for poor families. Eating the bad food causes serious health problems. 

Local teacher Mohammed Bah Abba was worried about this problem and decided to solve it. As a boy born into a family of clay pot(陶罐)makers, Mohammed knew that these traditional clay pots could keep water even when dry. In the 1990s he used this traditional knowledge and his understanding of science to invent a cooling system(冷却系统). It worked as a"desert fridge". 

Mohammed's cooling system is made up of two pots —a small pot inside a larger pot. In the space between the two clay pots, there is wet sand. People put the fruit and vegetables in the smaller pot, and cover it with a wet cloth(布). Then they leave the larger pot in a dry place. When water from the sand evaporates(蒸发), it causes the temperature in the pots to go down. This way the food in the smaller pot is cool. 

With the pot-in-pot cooling system, food stays fresh much longer. Mohammed's "desert fridge" has improved the lives of thousands of people. So in 2001 he won the Rolex Award for Enterprise, which is for the people who try to make the world a better place.
