A study published in International Journal American Journal of Epidemiology, from the Griffin Center for Prevention Studies (Yale-griffin Prevention Research Centre) Scientists have found that even if you exercise regularly, sitting too long can kill you.
The risk of death increases by 19% in people who sit for 6 or more hours a day, compared with less than three hours a day. The researchers say sedentary may kill you in 14 ways (disease), including cancer, heart disease, stroke, diabetes, kidney disease, suicide, COPD, lung disease, liver disease, peptic ulcer or other digestive diseases, Parkinson's disease, Alzheimer's disease, neurological disorders and musculoskeletal disorders. The easiest way to effectively prevent the risk of death from these diseases is to walk around more, which means that the less you sit, the better your health is (to a certain extent);
Use two minutes of standing or slight activity to break an hour of sitting posture or to help improve the body's cholesterol, blood sugar and blood pressure levels. Of course, this study does not point to the causal relationship, but it is clear that Americans now seem more willing to sit for long, such as watching TV, playing computer, calling, working and even entertaining. As people grow older and sit longer, their risk of chronic illness is increasing.
A study by researchers from Australia found that more than 90% of people who are not working hours are sedentary and more than half of them spend their time watching TV or computers. Researchers don't know why sedentary sitting is unhealthy, and they speculate that people who spend a lot of time on the couch may have other unhealthy behaviors, such as overeating and snacking. In addition, sedentary will also increase the body triglycerides, blood sugar, blood pressure and insulin levels, while sedentary also with obesity-induced inflammation directly related. This series of consequences may explain why sedentary life is directly linked to the risk of death from a variety of illnesses, including heart disease, liver disease, kidney disease, cancer, diabetes, and so on.
The researchers are not yet clear about why deaths due to diseases such as Parkinson's disease and Alzheimer's disease are directly related to sedentary life, possibly because the disease itself causes people to sit for long periods of time. Researchers, Patel, said the increased risk of death varied by disease, ranging from 10% of cancer to 60% of musculoskeletal disorders, in which researchers collected and analyzed data from nearly 128,000 men and women enrolled in the American Cancer Society's Prevention study, and at the beginning of the study,
All participants were suffering from major chronic illnesses, and in the following 21 years, about 49,000 individuals died in follow-up investigations. ' We all know that sitting for a long time every day is bad for your health, ' Dr. David Katz said. ' The study linked sedentary life to increased risk of death from a variety of illnesses, including heart disease and suicide, does that mean that prolonged sitting increases the risk of suicide? '
It seems incredible that people with depression may lack the motivation to get out of bed, and we know that daily exercise is crucial to mental health, so sedentary may increase the severity of disease in patients with depression. In the end, researchers say, although a lot of research is needed later to confirm that sedentary life increases the risk of premature death, how do you deal with this problem?
