What are the advantages and disadvantages of riding a bike every day

There are many benefits, such as 1. Bicycle is one of the best tools to overcome heart function problems. More than half of the people in the world die of heart disease. Riding a bicycle can not only compress the blood flow through the movement of the legs, but also draw the notes back to the heart from the vascular endings. In fact, it also strengthens microvascular tissue, which is called "collateral circulation". Strengthening blood vessels can protect you from the threat of age and keep you young forever. 2. Habitual cycling can enlarge your heart. Otherwise, the blood vessels will become thinner and thinner, and the heart will deteriorate. In your later years, you will experience the troubles it brings, and then you will find how perfect riding is. Cycling is a sport that needs a lot of oxygen. There was once an old man who finished riding 460 kilometers in six days. He said: "Old people should exercise at least three times a week to strengthen their hearts and restore normal function. You should let your heart beat violently, but not for long. In this way, it will be able to adapt to emergencies, such as catching up with a car or resisting difficulties. " 3. Cycling can also prevent high blood pressure, sometimes more effective than drugs. It can also prevent obesity and arteriosclerosis and make bones strong. Bicycle keeps you healthy without drugs, and it's harmless. Bicycle is a tool to lose weight. According to statistics, a person weighing 75 kilograms can lose half a kilogram by riding 73 miles at a speed of 9.5 miles per hour, but he must persevere every day. 5, cycling can not only lose weight, but also make your body more symmetrical and charming. People who lose weight through exercise, or people who diet while exercising, are in better shape and more attractive than those who only diet first. I don't know how to describe "more charming", but in fact, the strong muscles brought by exercise and the tiny ankles exercised by cycling are much better than the skinny blue blood diet! Proper exercise can secrete a hormone, which makes you feel happy and cheerful. According to experience, we know that cycling can produce this hormone. 6. Actually, cycling compresses blood vessels, speeds up blood circulation, and your brain takes in more oxygen, so you take in more fresh air. After riding for a while, you will feel clearer. 7. Riding this two-wheeled bicycle by yourself will make you feel very free and carefree. It is not only a weight loss exercise, but also an exile of spiritual pleasure. Of course, there are disadvantages: a research department in the United States confirmed that men who ride bicycles for a long time are prone to impotence. The existing bicycle seat is usually narrow and hard, and riding on it will cause great pressure on the genitals. The stress point of the bicycle seat is just between the anus and scrotum, and there is an artery here that can control the congestion of the penis. If you squeeze for a long time, it is easy to impotence. I know a lady who has been riding a bike to work every day for five years. Recently, she found that there was swelling between the thigh root and the external genitalia, and the lump gradually increased. When riding a bike under pressure, she often feels pain, and she feels uncomfortable when walking. After examination by the doctor, a tumor was found in her pubic sulcus, which may be caused by her long-term cycling, but she was not treated in time and was constantly stimulated. This kind of pudendal-femoral tumor usually occurs in women. Because the pelvis of women is wider, the pubic arch is lower than that of men, which matches the car seat, the pudendal-femoral tumor and its nearby soft tissues are easy to be rubbed. Therefore, women who ride bicycles all the year round, especially those who carry people and increase their load, are prone to pudendal-femoral tumors. Therefore, we should pay attention to: first, the seat of the bicycle is not easy to be too high, and it should be elastic to prevent the hips from twisting left and right when riding and reduce local friction. Second, when riding a bike, sit up straight with your hips and keep your legs balanced to prevent one side from exerting too much force and forming a tumor. Third, menstrual belts, sanitary napkins and shorts should be soft in texture, and it is best to ride less or not ride bicycles during menstruation. There are also: 1. The seat is too hard, so you can cover it with a soft seat cover made of foamed plastic to reduce the friction between the seat and the genitals. 2. Adjust the height and angle of the seat. If the seat is too high, the hips will inevitably move left and right when riding, which will easily cause perineal abrasions; The front of the car seat is upturned, which is more likely to damage the perineum. 3. When riding for a long time, we should pay attention to changing the riding posture, so as to move the center of gravity of the body and prevent a certain point of the perineum from focusing on it for a long time. 4. Don't ride the gearbox too fast and for too long for the first time, and then accelerate the timeout after the body adapts. 5. When riding a bicycle, if you find that the perineum has uncomfortable symptoms, you should find out the reasons in time. If there is a problem with the car seat, it is necessary to eliminate or improve it in time and pay attention to rest. After the symptoms are eliminated, ride a bike; If you can't get rid of the symptoms, you should go to the hospital and ask a doctor for examination and treatment.
