Blow out the candles Light a candle and blow it out with all the air in your lungs. If it cannot be blown out at the distance of 15 cm, it means that there is something wrong with lung function; If the distance is 5 cm and it can't be blown out, it means that the lung function is very poor. You should go to the hospital for a checkup.
Climb the stairs and climb to the third floor at the speed of daily walking. If you don't feel obvious asthma and chest tightness, it means that the cardiopulmonary function is good. Here is a suggestion: people over 45 years old should go to the hospital to check their lung function at least once a year; People who smoke for a long time and are exposed to indoor and outdoor pollution should have their lung function checked every six months from the age of 40. Take good care of your health, starting with the exam!
How to exercise, jog or climb stairs is the best way to test whether a person's lung function is strong. If you can run thousands of meters in one breath, your heart and lung function will be better.
Chinese medicine believes that the lung governs qi. The longer you hold your breath, the better your lung function will be. Generally speaking, just hold your breath for 30 to 40 seconds. But it also varies from person to person. Some people can reach 60 seconds. Such people are rare, and their lung function is the best and strongest. I can hold it for more than 40 to 50 seconds, which is not bad. I used to swim a lot, and I liked diving and exercise.
Any physical activity can increase vital capacity. However, different sports have different characteristics and have different effects on various organs of the human body. For example, swimming, diving, long-distance running, martial arts, antagonistic ball games and other sports have obvious effects on respiratory function, while weightlifting has little effect on respiratory function and relatively small vital capacity.
Under the premise of normal physical condition, you don't need to climb the third floor at a high speed and at a constant speed, and you don't need to stop halfway to observe your breathing.
The lung is the respiratory organ of the human body, and the alveoli are the places where the human body absorbs external oxygen into the blood and discharges high-concentration carbon dioxide from the blood. Therefore, the function of lung is mainly gas exchange function. Medical "lung function examination" is one of the necessary examination items for respiratory diseases, which has important reference value for the severity of respiratory diseases, judging the treatment effect and the prognosis of patients. However, lung function examination does not include breath-holding time, and it is impossible to judge a person's lung function simply from breath-holding value.
If there are no conditions, you can climb two more floors. If there are no symptoms of shortness of breath and chest tightness, your lung function is normal.
