A group of researchers from the University of Washington concluded that an excessive amount of time spent in front of the TV in a sitting position can be dangerous for people under the age of 50. Experts say that such a lifestyle is associated with an increased risk of bowel cancer.
The scientists analyzed information on more than 89 thousand American women, collected during the compilation of one of the largest databases of this kind. They were interested in how much time people devote to one or another pastime carried out in a sitting position – in particular, they were interested in how long they spent watching TV.
As it turns out, among people who spent more than an hour in front of the TV, the risk of developing cancer was 12 percent higher than those who preferred to spend time differently. Among those who watched TV for more than two hours a day, this risk increased by 70 percent. According to scientists, with respect to colorectal cancer, this dependence was traced to a greater degree than with respect to colon cancer.
However, the results did not really take into account the physical form of the participants and what their body mass index was.
Although studies of this kind do not always reveal the causal relationship between certain phenomena, experts are inclined to believe that watching TV may be a risk factor. According to the experts, this is the first scientific work in which the relationship between intestinal cancer and a particular habit, implying a sitting position and insufficient mobility, has been identified.
