Regular exercise may reduce cancer risk in women, but those benefits could be missed if the woman is sleeping too little, U.S. researchers said on Monday (17/11). Studies involving 5968 women in Maryland confirms previous findings that people who perform regular physical activity face a smaller risk for esophageal cancer.
But when the researchers examined women aged 18 through 65 years of diligent exercise every week, they found that sleep seems to play an important role in cancer risk.
People who sleep less than seven hours each night to face the risk of esophageal cancer 47 percent compared with those who sleep more among women who are physically active, the researchers reported that the meeting of the American Association for Cancer Research.
"We thought it was very interesting and arouse curiosity. It's like the first time doing research. That's not something that has been studied extensively, "said Jame McClain of the National Cancer Institute, part of the government's National Institutes of Health, said in a telephone interview.
McClain, who led the study, said it was unclear how exactly too little sleep may make people more susceptible to cancer. "Sleep has long been adequately related to health," said McClain.
U.S. Centers for Disease Control and Prevention (CDC) calls the lack of sleep as a public health problem that can not be considered, and declared the American people increasingly less sleep. The CDC states the percentage of adults who reported sleeping six hours or less per night increased from 1985 until 2006.
Experts say about sleeping with chronic sleep deprivation related to obesity, diabetes, high blood pressure, stroke, heart and blood vessel disease, depression, smoking and excessive drinking.
In addition, research has shown that people who exercise regularly face a lower risk of breast cancer, colon and other cancers. Many experts believe the impact of sport on the body's hormone levels, immune function and body weight may play an important role.
