When it comes to protecting the heart, most people will think of ways to stop smoking, drink less, eat less salt, and exercise more. But many people do not realize that there is another heart killer lurking around us, that is, sedentary and its “sequelae”.
Look around us, many young people sit at work all day, stare at the computer almost motionless, and even order takeout for dinner; When I got home, I watched TV and played games on the sofa, and I played until late at night. A survey shows that at present, 43% of people in China sit in the office for at least eight hours every day; Only 31% of people stretch occasionally; 27% of them went out of the office for a walk; More than 30% chose to play computer games or go to leisure websites during their breaks.
Unlike office workers, when the elderly are free, they linger on the card table and chess board, playing for most of the day; Many teenagers who should have been jumping are also attracted by computers and mobile phones, and outdoor activities are becoming less and less.
Sitting still for a long time will not only bring obesity, cervical and lumbar diseases and other problems, but also, like dominoes, will cause a series of cardiovascular and cerebrovascular injuries. If you get up abruptly after sitting for a long time, you will be a dangerous “killer”.
First of all, sitting in the same posture for a long time will reduce the contraction activity of lower limb muscles, resulting in a slow flow of human blood and an increase in blood viscosity, which creates conditions for the formation of deep vein thrombosis. If you suddenly move again at this time, such as getting up abruptly, stretching your waist and swinging your arms greatly, it is easy to drag unstable thrombus, make it fall off, cause thromboembolism, and cause ischemia, hypoxia and other symptoms in the corresponding parts. What is more serious is that if the thrombus dissociates into the lungs, it may block the pulmonary artery and cause pulmonary embolism, and in serious cases, it will endanger life in a short time. Some investigations have found that the sudden death of many “white-collar elites” in recent years is related to pulmonary embolism.
Secondly, sudden change of posture after a long time in the same posture can easily cause blood pressure fluctuation and “postural hypotension”, resulting in insufficient blood supply to the heart, brain and other organs. In serious cases, palpitation, dizziness, headache, even repeated syncope or stroke may occur. This is not uncommon among young people and adolescents who are thin and lack physical activity.
Finally, for the middle-aged and elderly people and patients with cardiovascular and cerebrovascular diseases, because of the poor flexibility of blood vessels, sudden pulling after sitting for a long time may also “tear” blood vessels and induce “aortic dissection” and other serious consequences. If rescue is not timely, the mortality rate can reach 30% ~ 40%.
Therefore, we need to face up to the harm of sedentary. The elderly, long-time sitting workers and desk workers should consciously “move”, and it is best to get up every 1-2 hours to exercise for a while, slowly stretch, shake your arms, and relax your spine; Or by stretching the toes, tilting the toes and other activities of the ankle joint, promote the blood reflux of the lower limbs. If conditions permit, it’s better not to lie on your stomach during the afternoon nap. If you can’t sleep, try to find a place to lie flat for a rest.
There should be a time limit for recreational activities such as playing cards. Once obvious swelling of legs and feet is found, do not massage or beat them vigorously at will, but touch the lower limbs under the guidance of doctors to avoid thrombus falling off. After getting up, if you have chest tightness, shortness of breath, severe chest pain and other symptoms, you should seek medical attention immediately.
Elderly patients with a history of coronary heart disease can usually take some Chinese patent medicines with high safety, coronary artery expansion effect and anti myocardial ischemia effect, such as Bubu Shenshao capsule, which is only composed of ginseng and white peony. It has very good safety. It can significantly improve chest tightness, shortness of breath, fatigue and other symptoms caused by cardiac ischemia. Long term use can prevent the recurrence of angina pectoris of coronary heart disease.
