Holding up your cell phone and playing "8", look at your lungs.

I do not know when to start, there are many friends in the http://www.aliyun.com/zixun/aggregation/960.html "> Friends Circle Hair" 8, in the back to add a sentence to explain: "This is a test of your vital capacity of the game, hold your breath (Reporter note: also has the transmission is the breath), picks up the handset to hit a "8", the normal person generally is 5 lines,9 rows is Superman, if less than 5 lines of the proof vital capacity not to please quit smoking, less than 3 line of hurriedly went to the hospital. "Yesterday afternoon, in many people's micro-trust circle, almost have become" 8 "of the ocean. and hit the "8" lung capacity game, yesterday also ran on Sina Weibo popular topic list of the 4th place.

Yesterday, your micro-trust circle was "8" brush screen?

I searched the game, which began appearing online the night before yesterday. In the night before 10 o'clock, as a well-known host of the Jiong on Sina Weibo sent a series of "8", and then remind everyone "if your friends circle or Weibo there is this situation please do not be surprised, this is just a test in the lung capacity of the game." ”

So this test division is not scientific?

Vital capacity is not necessarily proportional to the number of "8"

According to the "National Student Physique Health standard" requirements, primary school five or six grade, middle school, high school students are to do "vital capacity" Health physical examination project.

Rochuping, deputy director of the Geriatric center of the first affiliated hospital of Zhejiang University, said that lung capacity can indicate the maximum capacity of the lungs to breathe out the air, which can reflect the development level of the human body. Hospital respiratory Medicine has a special measurement of vital capacity of the instrument, using the "time Vital Capacity Method": Take a sip of energy, and then quickly exhale until the end of the call, recording 1th, 2, 3 seconds when the amount of air exhaled.

"The vital capacity we measure is the maximum amount of air that is exhaled for a certain period of time, and it is not necessarily associated with the exhalation time," he said. Therefore, breath-holding cell phone hit ' 8 ' lung capacity is not scientific. The length of breath can indicate how much air there is in the lungs, reflecting the capacity of the lungs to a certain extent, but it does not explain the maximum exhalation per breath. "said Dr. Luo.

In addition, from each person's state, age, gender, height, weight, weight, lung capacity of the standard is different, with the same test method measurement, nor scientific.

General adult male lung capacity is 3500 ml, female is 2500 ml. 25-Year-old-35-year-old adults with the largest lung capacity, children and the elderly are small.

The healthier people have the greater vital capacity. If suffering from respiratory diseases, such as tuberculosis, pulmonary fibrosis, atelectasis, lung capacity is significantly less than healthy.

Tall people than small people lung capacity, because the mold is big, the body in order to maintain normal operation, the organs are large, lung is also large, inhaled exhaled air volume, lung capacity of natural large.

Even the same person, lying more than standing when the lung capacity is small, because the lungs are a certain compression.

Also, the same person, continuous exercise for some time, the vital capacity will increase.

"So, breath-holding cell phone hit ' 8 ' lung capacity, some people play a lot, but the vital capacity is not necessarily very good." Some people do not play much, the vital capacity is not bad. "said Dr. Luo.

The most effective way to lift vital capacity

is to insist on physical exercise

The reason why the "8" test capacity is not scientific, but also with the dexterity of human fingers. Those who play the piano may play faster than those who do not, playing "8" more.

However, although the game itself is not scientific, but if through this game so that people will pay attention to the vital capacity is good, because the vital capacity is a very important health indicators.

Human cells consume oxygen all the time, and the body works only when the oxygen supply is adequate. The oxygen supply of the human body is all by the breath of the lungs to obtain, in the process of respiration, the lungs not only to eat oxygen, but also to the body of carbon dioxide excretion. The size of the vital capacity determines the degree to which the body obtains oxygen.

If a person has a small lung capacity, he even breathes, which will seriously affect his range of activities. Similarly, brain cells receive less oxygen, and his brain cells are not active in a high degree.

Each person has a corresponding vital capacity normal reference value, if below this value, the human body will appear oxygen supply deficiency performance, such as headache, dizziness, chest tightness, mental collapse, inattention, memory decline, insomnia and so on.

How to make your lung capacity a little bigger?

The most effective way is to adhere to physical exercise, preferably a long time regular aerobic exercise, such as long-distance running, swimming, playing football, playing basketball, turn around and so on. There are sports organizations have done research, middle and long distance runners and swimmers have an average lung capacity of more than 6000 ml.

In addition to physical exercise, we usually pay attention to their posture and breathing methods, do not hump, including chest, do more chest enlargement and stretching exercise.

Dr. Luo teaches us two breathing methods, which are clinically useful for patients with poor pulmonary function, and are good for ascending lung capacity: lip-breathing and abdominal respiration.

Shrink Lip Breath Method: Exhale, stomach, chest forward, mouth lip shrink into whistle-shaped, so that the gas through the narrowing of the lips slowly exhaled. Inspiratory and Expiratory time ratio is 1:2 or 1:3, as far as possible deep suction slow call. It is advisable to shrink the lip to a degree of difficulty. 7-8 times per minute, exercise two times a day, 10-20 minutes each time.

Abdominal breathing method: when inhaling, let the abdomen bulge, exhale when the abdomen concave breathing method. You can put your hands on the chest and upper abdomen, slowly inhale with the nose, the belly of the hands have to lift up the feeling, the hands of the chest does not move, exhale, abdominal contraction, abdominal hands have a sense of descent. Breathe deep and slow, try to use your nose instead of your mouth. Gradually develop a smooth and slow abdominal breathing habits.
