There are new findings that not enough sleep may cause people to gain weight.Researchers say a lack of sleep can produce hormonal changes that increase feelings of hunger.

In one study,researchers in the United States examined information on more than 1000 people.The people had taken part in a long-term study of sleep disorders.

Some people slept less than five hours a night.They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours.And they had 15 percent less of the hormone leptin.Experts say ghrelin helps make people feel hungry;leptin makes you feel full.

The scientists say these hormonal changes may be a cause of obesity in Western societies.They note the combination that limitation is common and is widely available.

The results were not affected by how much people exercised.People who are awake longer have more time to burn energy.But the researchers say loss of sleep may increase hunger especially for high-calorie foods,so people gain weight.It seems that,for survival,the body may be designed to store more fat during times with less sleep.

Researchers from Stanford University in California and the University of Wisconsin did the study.They found that the best amount of sleep for weight control is 7.7 hours a night.

The Public Library of Science published the findings in its journal Medicine.Internet users can read the full study,free of charge,at plos.org.

Shu Pulong has helped at least 1000 people bitten (咬) by snakes. “It was seeing people with snake bites (伤口) that led me to this career,” he said.

In 1963, after his army service, Shu entered a medical school and later became a doctor of Chinese medicine. As part of his studies he had to work in the mountains. There he often heard of people who had their arms and legs cut off after a snake bite in order to save their lives.

“I was greatly upset by the story of an old farmer I met. It was a very hot afternoon. The old man was pulling grass in his fields when he felt a pain in his left hand. He at once realized he had been bitten by a poisonous snake. In no time he wrapped a cloth tightly around his arm to stop the poison spreading to his heart. Rushing home he shouted ‘Bring me the knife!’ Minutes later the man lost his arm forever.”

“The sad story touched me so much that I decided to devote myself to helping people bitten by snakes,” Shu said.
