The harm of teenagers' lack of physical exercise, life lies in exercise, and now people's exercise time is greatly reduced because of study or work. If they lack exercise for a long time, it will have a great impact on their physiological function. So now many people choose exercise and fitness. Let's look at the harm of teenagers' lack of physical exercise.
The harm of teenagers' lack of physical exercise 1 1. Weaknesses and weaknesses
Some friends often get sick easily. They often feel weak, their hands and feet are cold, their physical strength is weakened, and they are getting tired of going out for a walk. A gust of wind blew and they were all in an untenable position, sweating all over. This is what we often say about physical weakness. This situation is very unhealthy.
And it is a state of psychological distortion. Physical and mental health exercise can make my body less sick, but I don't know that lack of exercise will make our body weak and sick, and our immunity will be reduced. Long-term past health conditions will make our bodies weaker and weaker, and it is very easy to get sick when going out with a hair dryer.
Second, hemorrhoids
Hemorrhoid is a disease, belonging to the intestine. People who are often sedentary are very prone to this disease. The arrival of this disease is very uncomfortable, and this pain is unforgettable. This disease is very painful to sit up. Surgery is needed to solve the fundamental problem.
The onset of hemorrhoids is caused by irregular diet and daily life. The most important cause of this disease is lack of physical exercise. It is not difficult to see that the lack of physical exercise is not a trivial matter. If you don't want to feel the pain of hemorrhoids, you need physical and mental health, regular food, clothing, housing and transportation, and daily exercise is also indispensable.
Third, fattening and fattening
Lack of physical exercise can also make our bodies fat. The most basic reason for obesity is that eating more and exercising less will lead to obesity. What we eat will be converted into calories, which will gradually deposit into human fat. The more body fat we store in our body, the more weight people will gain, and so will their weight. In order to prevent this problem, we need to exercise regularly.
The harm of teenagers' lack of physical exercise II. First, gain weight.
Lack of exercise is bound to make us fat. First of all, we must understand the principle of obesity. How does obesity come about? In fact, we eat too much and exercise too little. When we eat the calories in our stomachs, what we can't consume will become new fat, which will precipitate in the body in the form of fat. Therefore, lack of exercise will definitely make us fat. If you don't want to be super fat, you should start exercising.
Second, hemorrhoids
As the saying goes, ten men and nine ... Oh, forget it. Next, let's learn about a disease. The name of this disease is hemorrhoids. Hemorrhoid is an anorectal disease, which belongs to a common anal disease. Many people have had the experience of hemorrhoids attack. I believe this feeling, and I believe you will understand even if we don't make an introduction. It's really hard to forget It's very painful. If the symptoms of hemorrhoids are serious, surgery may be used to solve this problem. Hemorrhoids surgery is really in pain, so he doesn't need surgery.
Excessive internal heat, irregular diet and unhealthy work and rest will all cause the onset of hemorrhoids, especially lack of exercise, which is the first cause of hemorrhoids. It can be seen that lack of exercise is really not a good thing. You know, hemorrhoids surgery is a very painful experience. If we don't want to experience it, we should keep a good life rule from now on to ensure our health.
Third, irregular menstruation.
Irregular menstruation is a minor illness that belongs exclusively to women. Lack of exercise will definitely lead to deficiency of qi and blood, which may lead to irregular menstruation. In fact, not exercising often is really not a good thing. And irregular menstruation is really not a good thing for women. In addition, irregular menstruation often leads to dysmenorrhea. So I hope our female friends will do more exercise and go out more, and use exercise to ensure our health, without these little troubles.
Fourth, weak.
Some of my friends are weak and sickly, so they can't take them home when they go out to buy things. Even if there is a breeze blowing, they are as shaky as Alin Daiyu. This is a very unhealthy and morbid exercise, which can ensure that our bodies are strong and less sick. However, lack of exercise leads to our weakness and low immunity. In the long run, our bodies will become weak and easy to get sick.
That's a lack of exercise. I believe you already know the terrible lack of exercise? It turns out that lack of exercise is so horrible and can cause so much harm. Don't worry, we still have time to exercise from now on. Starting from tomorrow, no, going out to exercise from now on.
The harm of teenagers' lack of physical exercise. The significance of students' physical exercise
1. Effects of physical exercise on bones:
Bones support the human body, protect organs, and support and incite various movements of the human body.
Scientific research has proved that primary school students can strengthen their bones, promote their growth and development, and make their children's height grow rapidly by insisting on going to physical education class and taking an active part in physical exercise.
Because in sports, the traction and gravity of muscles on bones not only help to improve the shape and function of bones, but also help to form bones such as spine, chest, pelvis and arch of feet, and improve the mechanical properties of bones.
However, unscientific exercise can also bring bad effects to bones. Therefore, physical education teachers must guide students to exercise scientifically.
2. The influence of physical exercise on joints:
Through physical education class's study and exercise, the joint capsule, ligament and tendon are thickened and stretched, and the muscle strength and elasticity around the joint are increased. This can expand the range of joint activities, flexible and firm. For example, gymnasts and acrobats are very flexible, which fully shows the amazing role of physical exercise.
3. The effect of physical exercise on muscles:
Children's muscles are in the process of development, and the development speed of muscles in different parts of the body is also unbalanced. Persisting in physical education class's study and exercise can make obvious adaptive changes in the shape, structure, composition and function of muscles.
Muscles will become strong, strong and powerful. It can strengthen the metabolism of matter and energy in muscles. Can improve the nervous system's ability to control muscles. It can reduce the accumulation of fat in muscles, make children's muscles develop in a balanced way, maintain a good posture and prevent obesity.
Matters needing attention in physical exercise
First, avoid exercising under strong light.
Around noon, the hot sun is in the sky and the temperature is the highest. In addition to swimming, avoid exercise at this time and beware of heatstroke. In summer, the ultraviolet rays in the sun are particularly strong, and human skin can be burned by I ~ II after long-term exposure. Ultraviolet rays can also penetrate the skin and bones, radiate to the meninges and retina, and cause damage to the brain and eyeballs.
Second, avoid too long exercise time.
An exercise time should not be too long, generally 20 ~ 30 minutes is appropriate, so as to avoid excessive sweating and high body temperature, which may cause heatstroke. If you exercise for a long time, you can arrange 1 ~ 2 breaks in between.
Third, avoid drinking plenty of water after exercise.
A lot of exercise and sweating in summer, so drinking a lot of water will increase the burden on the blood circulation system, digestive system, and especially the heart. At the same time, drinking water will make you sweat more and further lose salt, which will cause convulsions, cramps and other symptoms.
Fourth, avoid taking a cold bath immediately after exercise.
Because the heat generated by summer exercise increases rapidly, the capillaries of the skin also expand a lot, helping the body to dissipate heat. Sudden supercooling stimulation will suddenly close the pores that have been opened on the body surface, leading to disorder of internal organs of the body, abnormal temperature regulation of the brain, and even illness.
