The danger of sedentary 4 points video commentary!

Professor Ye Huiyang said: Knee osteoarthritis is one of the most common diseases in China, with a total prevalence of 15.6%. The prevalence of knee osteoarthritis increases with age. The prevalence of knee osteoarthritis is doubling in 10 years among people over 50 years old. Knee osteoarthritis is currently the second most disabling disease in the world.

The harm of sedentary is not only knee injury, but also from head to foot. The World Health Organization has already listed sedentary as one of the top ten deadly pathogens.

Sitting posture for 1 hour, blood concentration in the lower limbs, circulation weakened, insufficient cerebral blood supply, hypoxia, easy dizziness, low mood, reduce thinking vitality, and even an important factor of Alzheimer's disease.

Sitting still for a long time will slow down the blood circulation, cause the heart function to decline, and cause myocardial atrophy. For middle-aged and elderly people suffering from atherosclerosis, sedentary blood circulation retardation can also induce myocardial infarction and cerebral thrombosis。

Long-term sedentary, reduced fat burning, increased cholesterol, may block the heart, blood vessels, and increase cardiovascular and cerebrovascular diseases. The risk of coronary artery atherosclerosis increases by 12% after sitting for an extra hour every day.

Sitting for a long time, the contraction of leg muscles decreased, the blood flow velocity of lower limbs slowed down, and the incidence of thrombosis increased. The risk of deep venous thrombosis in lower extremities is doubled when a person sits for more than three hours a day. Sitting for more than 12 hours continuously increases the risk of pulmonary embolism. Especially in middle-aged and elderly people, high blood lipid, high blood viscosity and long-term sitting are potential terrible risk factors.

Long-term sedentary blood circulation slows down, but also lead to insufficient blood supply to the brain, mental distress, manifested as physical fatigue, dizziness and other symptoms.

Neck, shoulder, waist and back in a tense fixed position for a long time will not only lead to poor local blood circulation, but also lead to neck, shoulder, waist and back stiffness, soreness, headache and cervical spondylosis.

The sedentary exercise volume is small, the lungs can not get effective exercise, will affect the heart and lung blood supply. Pulmonary emphysema infection and other common lung diseases in the elderly are mostly related to the decline of lung function.

When cells are in idle muscle, the pancreas reacts slowly and produces more insulin, leading to diabetes, long-term sedentary, and an increased risk of type 2 diabetes by 112%.

Sitting for a long time can easily cause gastrointestinal peristalsis to slow down, the secretion of digestive juice from the digestive glands to decrease, appetite loss and other symptoms, aggravating the symptoms of the digestive system such as abdominal distension, constipation and indigestion.

In sedentary people, intestinal and gastric peristalsis is slowed down, harmful ingredients are easily retained in the colon, stimulating intestinal mucosa, coupled with abdominal, pelvic, lumbosacral blood circulation is not smooth, intestinal immune barrier function is reduced, increasing the risk of colon cancer. "Nine haemorrhoids in ten people" can easily lead to haemorrhoids if they keep sitting posture for a long time.

The American Cancer Society has released a new 14-year study of 120,000 people, suggesting that sitting for more than six hours a day may increase the risk of premature death and increase the risk for women.

Australian researchers found that people who sat and watched TV for more than four hours a day had an 80% higher risk of death from cardiovascular and cerebrovascular diseases and 46% higher risk of death from other causes than those who watched TV for less than two hours.
