What is the lung capacity of children?

Many parents hope that their children will not be troubled by health problems during their growth. Lung capacity is the simplest and most effective way to detect the development of children's lungs. However, low lung capacity will have a great impact on children's normal life and physical health, and may even affect children's brain hypoxia. However, if it can be discovered early and exercise can be carried out, it can be greatly improved. Let's take a look at the lung capacity of children.

What is the lung capacity of children?

Average reference value of primary school students' vital capacity: boys - 7 years old 1342ml, 8 years old 1496ml, 9 years old 1972ml, 10 years old 1843ml, 11 years old 2010ml, 12 years old 2200ml. Girls - 7 years old 1213ml, 8 years old 1354ml, 9 years old 1516ml, 10 years old 1685ml, 11 years old 1883ml, 12 years old 2077ml. Life care: Active physical exercise, such as long-distance running, playing ball, etc. can increase vital capacity.

Ways to improve lung capacity

1. Deep breathing method: First, inhale slowly through the nostrils to fill the lower part of the lungs with air. During inhalation, the abdomen will slowly bulge as the chest cavity lifts upward and the diaphragm moves downward. Then continue to inhale to fill the upper part of the lungs with air. The ribs will then lift up and the chest cavity will expand. This process usually takes 5 seconds. Finally hold your breath for 5 seconds. After a period of practice, you can increase the breath-holding time to 10 seconds or even more. After the lungs have absorbed enough oxygen, exhale slowly, and the ribs and sternum will gradually return to their original positions. After pausing for one or two seconds, start again from the beginning and repeat for 10 minutes. After practicing for a long time, it can become a normal breathing method.

2. Quiet breathing method: Press the right nostril with your right thumb, and slowly take a deep breath through the left nostril, consciously imagining that the air is flowing towards the forehead. When your lungs are saturated with air, press your left nostril with the index and middle fingers of your right hand, hold your breath for 10 seconds and then exhale. Then start again by holding the left nostril. Do 5 times on each side.

3. Sleep breathing method: Lie on the bed, place your hands flat on both sides of your body, close your eyes and start taking deep breaths. Slowly raise your arms above your head, close to your ears, with your fingers touching the headboard. This process takes about 10 seconds, and both arms are restored at the same time, and repeated 10 times. This method can also help you fall asleep peacefully.

4. Exercise breathing method: Actively increase your breathing volume while walking or jogging, inhale slowly and exhale quickly. When inhaling slowly, slowly expand your chest as you inhale, and exhale quickly. Do not exercise less than 20 times each time, and you can do it several times a day.

5. Maintain the correct posture of keeping your head up, chest out, and back straight

In daily life, whether sitting, standing or walking, if you can maintain the posture of keeping your chest up, head up and back straight for a long time, your lung capacity can be increased by 50% to 20%, and the amount of oxygen obtained by various tissues of the body will also increase accordingly.

6. Adhere to appropriate physical exercise

Long-distance running and swimming, after several years of training, my lung capacity is much larger than others.

According to your age, choose 2 to 3 physical exercise programs. Don't be greedy and don't exercise excessively. Instead, do what you can, persevere, and proceed step by step.

7. Keep participating in appropriate physical activities

According to age, gender and occupation, people who participate in physical activities and engage in mental work also need to participate in appropriate physical activities regularly.

8. Do chest expansion exercises every day

First, clench your fists, then pull and push forcefully to the left and right, up and down, forward and backward about 50 times. At the same time, stretch and move your cervical spine 10 times.

9. Prevent smoke from damaging your lungs

Pay attention to air hygiene in living rooms, workplaces and study places. Open windows in living rooms frequently to promote air circulation, eliminate indoor smoke in a timely manner, and smokers are encouraged to quit smoking.

The above is an introduction to children's lung capacity. After understanding it, we know that lung capacity is affected by age, height, etc. Therefore, once a child has low lung capacity, we must help the child to exercise more outdoors. In order for the child to grow up healthily and happily, we must pay attention to the balance of nutrition in the diet and take the child to the hospital for physical examinations regularly.
