In recent years, the Internet industry frequently broke out the news of overwork death. We often pay attention to the working hours and staying up late of Internet people, but seriously ignore that sedentary is also the top priority of health.
1. Cervical Spondylosis
The Department of Orthopedics of the Third Hospital of Peking University investigated and counted nearly 300 cervical spine cases from across the country. It was found that young and middle-aged people under the age of 40 accounted for 48.1% of the population with cervical spondylosis, and men made 3% of women. The prevalence of long sitting operations such as finance, assembly line work, text work, teachers, graphic design, it and drivers accounted for the top seven respectively.
2. Lumbar Disc Injury
Research shows that if the correct sitting posture is maintained, the pressure in the lumbar intervertebral disc is 6 times that in the supine position. If the sitting posture is poor, the pressure will rise to 11 times that in the supine position. Working for a long time makes the back muscles in an extremely traction state, which is rugged and easy to cause low back muscle strain and lumbar disc herniation.
3. Lower Extremity Thrombosis
Sitting for a long time will reduce the contraction of leg muscles and slow down the blood flow velocity of lower limbs, thus increasing the risk of thrombosis. A study published in the annals of the Royal Medical Association of Britain points out that people who sit in a fixed position for more than 3 hours a day have twice the risk of lower extremity deep venous thrombosis as other people.
4. Other Diseases that Sedentary May Cause
First, heart disease. Just doing things, muscles burn less fat, blood flow is slow, fatty acids precipitate in blood vessels, which is very easy to block heart blood vessels. A study by the University of South Carolina found that individuals WHO sit over twenty three hours per week are sixty fourth a lot of seemingly to die of a coronary failure than those that sit but eleven hours per week.. Second, hemorrhoids. If you keep sitting for a long time, the abdominal blood flow will slow down, the venous blood of the lower limbs will not jump back, and the blood circulation will be hindered. In this case, rectal veins are prone to varicose, leading to blood stasis, and finally form a venous mass, namely hemorrhoids. Third, diabetes. The University of Leicester study found that a sedentary lifestyle can increase the risk of type 2 diabetes by 112%. The researchers analyzed that due to sedentary exercise, physical distribution of neutral adipose tissue will be abnormal, leading to centripetal obesity, resulting in a metabolic field, inducing diabetes. Second, Alzheimer's disease. Muscle activity can help pump fresh blood to the brain and promote the brain to release all kinds of chemicals that enhance the brain and improve mood. A study by the University of California, San Francisco found that sedentary is an important factor in increasing the risk of Alzheimer's disease. In addition, sedentary is also at risk of cancer. Researchers found that sedentary was associated with increased risk of colon cancer, breast cancer and endometrial cancer. Because the number of immune cells in the human body increases with the increase of activity, sedentary will make the human body lack enough immune cells.
Kenneth K. hansra, director of rehabilitation medicine of spinal surgery in the United States, showed that when the forward tilt angle of the human head becomes larger, the pressure on the cervical spine will also increase significantly. When sitting upright, the lumbar spine carries 150% of the pressure, while when bending forward seriously, the spine carries 270% of the pressure. Facebook 200 employees choose the office form of "sitting and standing alternately". Google also included the standing desk in the company's health care plan.
During the epidemic period, when working at home, the time of sitting every day increased sharply, the cervical spine and neck also hurt, and it was a feeling that it would not be comfortable to move around. A study by the University of Queensland in Australia found that sitting for an hour is equal to smoking two cigarettes and losing weight for 22 minutes. The World Health Organization has long said that sedentary is one of the top ten culprits of death and treatment. More than 2 million people worldwide die from sedentary every year. It is estimated that by 2022, 70% of the world's diseases will be caused by sedentary.
The disadvantages of sedentary are not only these. As office workers, they sit and work for no less than 8 hours every day. In the long run, the harm to people's health is self-evident. Therefore, it is particularly important for people's healthy development to buy a height adjustable desk to meet the needs of sitting and standing alternately.
