As the saying goes, "the old legs of people wither first, and the old roots of trees wither first." Our daily activities are inseparable from our legs: running, walking, standing and so on. The energy consumed by legs accounts for a large part of our total energy consumption.

The leg is the "second heart" of the human body. Because the distance between the lower limbs and the heart is too far, the strength of leg muscle contraction can drive the blood circulation of the lower limbs like heart contraction, and the contraction of calf muscle controls the venous reflux of the lower limbs, so that the blood of the lower limbs flows back to the heart, and the heart controls the arteries, so the function of the leg is similar to that of the heart.

Legs support the weight of our whole body. Legs have more than half nerves and more than half blood vessels, so the importance of legs is self-evident. From the perspective of traditional Chinese medicine, the Foot Sanyang Meridian and Foot Yin San Meridian pass through the calf, and our calf also has many acupoints, which are very important for the rise and fall of human qi and blood, and are the main roads for the human body to communicate with the upper body and the lower body.

0 1? If we have a disease and don't know it, then we may know it by observing our legs.

● For example, when our body is short of calcium, the possibility of calf cramps will be great.

● If the human body forms a thrombus and adheres to the blood vessel wall of the calf, the calf will swell. At this time, we should be vigilant. If embolism persists, it is likely to further cause pulmonary embolism, which may lead to death in severe cases.

● The cold calf is also the condition that the calf reflects the illness of the human body to us. When our constitution is weak and cold, it will lead to cold in our calves, because of poor blood circulation around us, metabolic disorders or cardiovascular diseases may occur. At this time, you should seek medical attention in time to avoid more serious situations.

● If standing for a long time will cause numbness in the legs, the symptoms will disappear after a few minutes. If you don't sit for a long time and stand for a long time, you will be alert, which may be a sign before a myocardial infarction.

● Unilateral hand and foot weakness will occur before stroke. So when our legs are uncomfortable, don't underestimate them.

02? Legs are very important to the human body, so what will hurt our legs?

■ Many times, people don't pay enough attention to leg warmth. In summer, because of the hot weather, they wear shorts and short skirts. I don't know if this will have a bad effect on the blood circulation of the calf. A cold calf for a long time may cause arthritis.

■ Standing and sitting for a long time can cause damage to the legs. Standing for a long time makes the calf muscles contract and affects the blood circulation of the calf; Sedentary will make the calf muscles in a state of relaxation for a long time, reduce the elasticity and toughness of the calf muscles and accelerate the aging of the calf.

■ Improper clothes can also cause leg injuries. With the development of the times, people's aesthetics have also been divided, and tights conform to many people's aesthetics. Some people often wear tights, but they don't know that tights will have an impact on human health. Wearing too many tights will hinder the blood circulation of the calf. In severe cases, it will lead to insufficient blood supply to the whole body, causing varicose veins of the calf and making blood vessels protrude from the skin surface.

Many girls who love beauty like wearing high heels. If you can wear it as little as possible, high heels will cause calf muscles to contract for a long time, which will easily lead to varicose veins. In addition, the design of high-heeled shoes will make all the weight of the human body fall on the palm of the front foot, which is very harmful to the feet. And wear high heels for a long time and then change into flat shoes, because the state of the front and rear calves is different, one is in a state of muscle contraction and the other is in a state of muscle tension, which will cause calf pain.

■ Proper exercise is not only beneficial to the legs, but also helpful to the physical and mental health of the human body. However, excessive exercise can easily cause calf muscle strain and accelerate leg aging. Excessive exercise is not only harmful to the legs, but also may damage the immune system.

■ Some people have developed the bad habit of crossing their legs. According to research, when people cross their legs, the blood circulation of the oppressed legs is greatly hindered, causing varicose veins, and in severe cases, it will cause vascular embolism, especially in patients with hypertensive heart disease. Crossing your legs for a long time is not conducive to the relief of your illness, or even worse. Moreover, crossing your legs has a great influence on the bones of your legs, which may cause bone lesions after a long time.

03? After knowing the possible injuries to the legs, how to maintain the legs?

▲ Strengthen the physical exercise of the legs.

Regular outdoor exercise can get sunshine, which is helpful to the formation of vitamin D and can strengthen our bones. We can strengthen the blood circulation of the legs by riding mountain bikes, jogging, even Tai Chi and other aerobic exercises, which can increase the elasticity of the blood vessel wall of the legs and delay the aging of the legs. Try not to take the elevator when going up and down stairs at ordinary times, increase the number of stairs to meet daily leg exercise.

Research shows that walking is actually a good and simple way to strengthen leg exercise. We can go for a walk in the park after dinner every day instead of sitting on the sofa watching TV. Exercise can effectively prevent falls and is the most effective way to delay leg aging.

▲ soaking feet

When we exercise, we can choose to soak our feet to relieve leg and foot fatigue, relax our body and mind, improve blood circulation and promote metabolism. If necessary, you can choose to add Chinese medicine, which will also be helpful for the treatment of some diseases. For example, in hot summer, people's consumption of cold drinks and the use of air conditioners increase, resulting in excessive water in the body. At this time, ginger can be added to eliminate moisture in the body.

▲ massage

Massage is actually the best choice after our exercise. Soaking feet can not only relax the tense muscles after exercise, but also accelerate blood circulation, which is also helpful to the metabolism of the human body and has the effect of burning fat. Moreover, many acupoints on the feet correspond to our internal organs. We can check their positions online, which can relieve fatigue and promote blood circulation, but also warm the internal organs.

The times are progressing and science and technology are developing, but our physical fitness is getting worse from generation to generation. Therefore, we should be responsible for our own health, starting with caring for our legs, developing good living habits and maintaining a good mentality, so as to achieve the goal of "helping our legs to prevent old age and eliminate all diseases".
