While several research studies have earlier reported that sitting for long hours are linked to the risks of Type 2 diabetes and cardiovascular disease, the recent studies have found that sitting long time can also lead to the risk of developing several cancers.
According to the research study published in the journal Cancer Epidemiology, Biomarkers & Prevention, they have found that women who sat more than 6 hours a day were at a higher risk of developing breast cancer, ovarian cancer and blood cancer, compared to women who sat less than 3 hours a day.
The study also found that Longer the time spent sitting is associated with higher risk of total cancer risk among women. Women who sat for more than 6 hours had 10 percent increase in their risk of developing cancer. Along with the sitting hours, the research team have also considered BMI and physical activity levels as well.
On the flip side, most men did not appear to be at the increased risk of cancer due to sitting for long hours. Only Obese men however were associated with 11 percent increased risk of developing cancer, when sitting for long periods of time.
Sitting for long hours and being less physically active might affect how metabolic chemicals in the body regulate numerous systems in the body. Women who sat for 6 or more hours daily were 37 percent more likely to die in about 13-year period compared to those who sat for 3 hours or less daily.
“Several factors could explain the positive association between time spent sitting and higher all-cause death rates. Prolonged time spent sitting, independent of physical activity, has been shown to have important metabolic consequences, and may influence things like triglycerides, high-density lipoprotein, cholesterol, fasting plasma glucose, resting blood pressure and leptin, which are biomarkers of obesity and cardiovascular and other chronic diseases,” the researchers added.
Sitting, watching television or working at a computer continuously can increase cancer risks. So, take quick walks, take the stairs when exiting or entering the office, go for stretches and break for 5 minutes every one hour to lower the cancer risk.
