Sedentary, reduce fat burning, increase cholesterol, may block the heart and blood vessels. , increase cardiovascular and cerebrovascular diseases. Sedentary, calcification accumulates in arteries, leading to arteriosclerosis. Sitting for an hour every day increases the risk of coronary atherosclerosis 12%. Sedentary, leg muscle contractility decreased, lower limb blood flow slowed down, increasing the incidence of thrombosis. People who sit still for more than 3 hours a day have a double risk of deep venous thrombosis of lower limbs, and sit still for more than 12 hours continuously, which increases the risk of pulmonary embolism. Especially middle-aged and elderly people have high blood lipids and high blood viscosity, and sedentary is a potential risk factor.
Sedentary people, intestinal peristalsis and gastric peristalsis weaken and slow down, and harmful components are easy to stay in the colon and stimulate intestinal mucosa. In addition, the poor blood circulation in abdominal cavity, pelvic cavity and lumbosacral region leads to the decline of intestinal immune barrier function and increases the risk of colon cancer. "Ten people and nine hemorrhoids" are prone to hemorrhoids after sitting for a long time.
The American Cancer Society announced the latest research results of 14 years10.2 million people. Sitting for more than 6 hours a day may increase the probability of premature death, and the risk is higher for women. Australian researchers have found that compared with people who watch TV for less than 2 hours a day, people who sit and watch TV for more than 4 hours a day have an 80% increased risk of dying of cardiovascular and cerebrovascular diseases and a 46% increased risk of dying of other causes.
I'm sorry to tell you that sedentary injury is difficult to recover. More and more studies have found that sedentary is an independent risk factor. Independence means that even if we try our best to exclude physiological indicators such as age, gender and body mass index, as well as social indicators such as income and education, and observe the impact of sedentary on health without interference, we can find that sedentary is not good for health. Whether you exercise regularly or not, people who sit for a long time every day have an increased risk of heart disease, diabetes, cancer and premature death. So I still want to emphasize the previous sentence. Everyone should reduce the time of sitting still.
