Regelbundet hushållsarbete minskar risken för tarmcancer

An hour's vigorous housework every day can help to reduce the risk of some types of bowel cancer according to a new Cancer Research UK report.

Cleaning the kitchen floor and hoovering the stairs can use as much physical energy as a gym session on the treadmill or a brisk walk and all types of activity can cut the risk of colon tumours.

For tumours on the right side of the colon the risk was reduced by as much as 35 per cent in the most active people. For active people who are not overweight with a Body Mass Index (BMI) of less than 25 the risk was reduced even further.

Scientists concluded that exercise was most beneficial in reducing right-sided colon cancer risk in both men and women who already had a healthy weight. But it also benefited to a lesser extent those who were overweight but not obese.

One hour a day of vigorous physical activity or two hours of moderate activity would be enough to reduce the risk of colon, though not rectal cancer.

Dr Lesley Walker, Cancer Research UK's director of information, said: "This is a very large study which should remove any doubt about the benefits of exercise in relation to reducing the risk of bowel cancer. It is important for people to understand that they can take steps in their daily routine to reduce cancer risk. You don't need to join a gym to get the benefit of exercise. If regular brisk walking or going for a run doesn't appeal you can take a tip from TV's Kim and Aggie and do some strenuous housework. Cleaning windows, vacuuming and scrubbing floors burn off a lot of calories. So does gardening or cleaning the car. If you combine regular physical activity with a good diet you are more likely to maintain a healthy body weight which will also significantly help to reduce your risk of bowel cancer. What is particularly interesting about this study is the correlation the scientists have found between exercise and cancers on the right side of the colon. We do not know the reason for this although physical activity is known to stimulate waves of muscle contraction down the right side of the colon which accelerates movement of waste and the possible cancer- causing agents in it."

Kim and Aggie welcomed the benefits of housework. "It's amazing how much energy you use just by doing basic housework," they said. "Thorough cleaning involves bending and stretching, climbing stairs, using a vacuum cleaner, scrubbing the bath and lots more. It all adds up to burning off plenty of calories which helps keep weight down. It's good to know that a daily cleaning routine can help keep you fit and healthy." ¹

Hushållsarbete är alltså inte så hemskt som feministerna vill få det till; både män och kvinnor bör slå två flugor i en smäll och lära sig att sköta om både sig själv och sitt eget hem.
