This is the situation of many people nowadays. The weather is gradually turning cold, the human body in the cold stimulation, blood vessels will be constricted, the metabolism will not adapt. In this case, it is easy to cause joint pain. This is actually a manifestation of ischemia, very normal, but many middle-aged and elderly people once the pain is immediately rest practice is very wrong. The consequences of not exercising will cause muscle atrophy, middle-aged and elderly people’s joints are more prone to wear and tear, and finally cause joint diseases. What should be done? Do not not exercise, but also do not exercise strenuously, to let the joints have a slow process of adaptation. Let the joints have a slow adaptation process. Without weight bearing, let the joints “move” healthily. In the process of exercise, remember to gradual, but also to do a good job of keeping warm. Special reminder, middle-aged and elderly people in sports should not wear knee pads. First, because the knee pads are too tight will not be conducive to blood circulation; second, with the knee pads, knee joints will be dependent on them. Three major knee care misunderstandings, be careful not to repeat In daily life, many people encounter joint problems always do not pay attention to, or there are cognitive or care misunderstandings. The following are three common ones. 1, knee pain ≠ calcium deficiency Many people will have this idea: joint pain is caused by calcium deficiency. Knee pain and calcium deficiency is not directly related. Most of the knee pain in the elderly is caused by the wear and tear of the knee cartilage. 2, joint pain can not walk immediately use crutches Joint discomfort, we should consult a doctor in time, listen to the advice of a professional doctor. If your lower limbs do not have obvious deformities or muscles are not irreversibly weakened, otherwise do not easily use crutches. “Using crutches is, in principle, going ‘downhill’!” 3, joint pain on the application of medicinal wine For many elderly joint pain like to apply medicinal wine, medicinal wine treatment by activating blood stasis can indeed achieve the effect of pain relief, but treating the symptoms does not cure the root cause. However, it does not cure the symptoms but not the root cause of the problem. Wine therapy can be used as an adjunct, but not as a primary treatment. Pay attention to the signals of discomfort, diagnosis and treatment should be early. There is a process of degeneration of knee joints. At the beginning of the knee cartilage damage lesions in a very small range or very light degree, only going upstairs or downstairs in the patellar cartilage is too much pressure in the case of pain, and when walking on a flat surface patella and femur pressure is very small, the pain does not exist. Don’t ignore it at this point, it’s the bone and joint sending you danger signals. When the cartilage is rough or has small cracks, the deterioration of the knee joint can be slowed down if cartilage repair and lubrication or reduction of wear and tear can be facilitated at this time. Once the cartilage surface is damaged, it becomes moderately damaged if it is not repaired within a certain period of time. Therefore, active remedial measures should be taken when the articular cartilage is damaged at an early stage. How to prevent knee and osteoarthritic degeneration? Obesity is an important causative factor in the development of this disease. Weight loss can prevent or minimize joint damage and reduce the pressure on the diseased joints. Avoid prolonged standing and long-distance walking, timely and proper treatment of joint trauma, infection, metabolic abnormalities, osteoporosis and other primary diseases. Adhere to the appropriate amount of physical exercise, prevention and treatment of osteoporosis Regular exercise can help to protect the joints and prevent osteoarthropathy by strengthening the supportive role of muscles, tendons and ligaments. Pay attention to keep the joints warm, cold joints often trigger the occurrence of this disease. It should be based on dietary supplements, pay attention to the balance of nutrition, eat more dairy products, soy products, vegetables and seaweed, seaweed, fish and shrimp and other seafood. At the same time, we should see more sunlight and supplement vitamin D to promote calcium absorption.
