Regular exercise can reduce a woman’s risk of cancer, but the benefits may slip away if she gets too little sleep, U.S. researchers said on Monday. The study involving 5,968 women in Maryland confirmed previous findings that people who do regular physical activity are less likely to develop cancer.
But when the researchers looked at the women ages 18 to 65 who were in the upper half in terms of the amount of physical exercise they got per week, they found that sleep appeared to play an important role in cancer risk.
Those who slept less than seven hours nightly had a 47 percent higher risk of cancer than those who got more sleep among the physically active women, the researchers reported at a meeting of the American Association for Cancer Research.
“We think it’s quite interesting and intriguing. It’s kind of a first look into this. It isn’t something that has been widely studied,” James McClain of the National Cancer Institute, part of the U.S. government’s National Institutes of Health, said in a telephone interview.
McClain, who led the study, said it is unclear exactly how getting too little sleep may make one more susceptible（易受感染的） to cancer. “Getting adequate sleep has been long associated with health,” McClain said.
The U.S. Centers for Disease Control and Prevention calls sleep loss an under-recognized public health problem, saying Americans are getting less and less slumber. The CDCP said the percentage of adults reporting sleeping six hours or less a night increased from 1985 to 2006. Sleep experts say chronic sleep loss is associated with obesity, diabetes, high blood pressure, stroke, cardiovascular disease, depression, cigarette smoking and excessive drinking.
In addition, research had shown that people who get regular exercise have a reduced risk of breast, colon and other types of cancer. Experts think the effects of exercise on the body’s hormone levels, immune function and body weight may play an important role.

Phys ed (physical education) is making a comeback as a part of the school core curriculum, but with a difference. While group sports are still part of the curriculum, the new way is to teach skills that are useful beyond gym class. Instead of learning how to climb a rope, children are taught to lift weights, balance their diets and build physical endurance. In this way, kids are given the tools and skills and experiences so they can lead a physically active life the rest of their life.
Considering that 15 percent of American children aged 6 to 18 are overweight, supporters say more money and thought must be put into phys ed curriculum. In many cases, that may mean not just replacing the old gym-class model with fitness programmes but also starting up phys ed programmes because school boards often “put P. E. on the chopping block, cutting it entirely or decreasing its teachers or the days it is offered”, says Alicia Moag-Stahlberg, the executive director of Action for Health Kids. The difference in phys ed programmes is partly due to the lack of a national standard. “Physical education needs to be part of the core curriculum,” she added. The wisdom of the new approach has some scientific support.
Researchers at the University of Wisconsin have demonstrated how effective the fit-for-life model of gym class can be. They observed how 50 overweight children lost more weight when they cycled and skied cross-country than when they played sports. The researchers also found that teaching sports like football resulted in less overall movement, partly because reluctant students were able to sit on the bench.
Another problem with simply teaching group sports in gym class is that only a tiny percentage of students continue playing them after graduating from high school. The new method teaches skills that translate to adulthood.
