Does spirometry decrease? Is there any harm in having a particularly low lung capacity? What can I d

Yes, regular inactivity, and the habit of smoking and drinking will affect lung capacity.

Low vital capacity is a manifestation of restrictive ventilation disorder. Long-term lack of lung capacity can lead to headaches, dizziness, chest tightness, listlessness, poor concentration, memory loss, insomnia and other unsatisfactory reactions, which will not only affect study and work, but also cause many irreparable losses to physical health.

Ways to improve lung capacity:

1.Chest expansion exercises: Do chest expansion and chest stretching 50 times twice a day, preferably after waking up and before going to bed, which can effectively prevent the decline of lung capacity.

2.Straighten your chest: If you stick to the correct posture of raising your head and waist for a long time, your lung capacity can increase by 5% to 20%, and the amount of oxygen obtained by various tissues of the body will also increase. Sticking to a chest lift also boosts the brain's memory.

3.Walking in the water: If you can't swim, it is recommended to walk in the water, with a certain speed, and it is best to swim above the waist.

Take a quick 15-minute break, take a 5-minute break, walk for another 10 minutes, take a 5-minute break, and walk for another 15 minutes. Practiced twice a week, the results are obvious.

4.Show off your singing voice: Singing is also a great way to increase your lung capacity. The beautiful melody of the song can make people intoxicated and forget their worries; When speaking, pay attention to luck and adjust the mind, and breathe evenly and deeply, which is beneficial to the body and mind.

5.Eat apples regularly: Researchers at the University of Nottingham in the UK have found that apples and tomatoes are the best at helping the body breathe more easily.

Eating at least 5 apples or 3 tomatoes per week can significantly improve lung function. At the same time, eating bananas regularly will not cause breathing difficulties.

Effects of low lung capacity:

If the spirometry test value is low (compared with the normal value), it means that the body's oxygen uptake capacity and exhaust gas ability are poor, and the oxygen ** inside the human body is not sufficient, and some of the body's work cannot be normal.

Once the body needs a large amount of oxygen consumption (such as long-term study, work, strenuous exercise), there will be a serious shortage of oxygen, resulting in headaches, dizziness, chest tightness, malaise, poor concentration, memory loss, insomnia and other adverse reactions, which will not only affect study and work, but also cause many irreparable losses to physical health.

The role of spirometry:

Lung capacity is closely related to a person's breathing. Physiological studies have shown that the organs, systems, tissues, and cells of the human body are consuming oxygen all the time, and the body can only work normally when oxygen is sufficient.

In the process of breathing, the lungs not only have to take in oxygen, but also excrete the carbon dioxide metabolized in the body. Li Jinjing.

Spirometry standards for each age group are as follows:The vital body mass index is 46. The evaluation criteria for spirometry body mass index are:

Excellent: 75ml kg or more for men, 74 70ml kg for women; Good: 69 64ml kg for males, 63 57ml kg for females; Pass:

56 54ml kg for males, 53 44ml kg for females; Fail: 43ml kg or less.

To judge a person's lung capacity, there is a central criterion is the lung capacity body mass index, that is, the relative value of lung capacity per 1kg of body weight to reflect the correlation between lung capacity and body weight, which is used to conduct an objective quantitative comparative analysis of individuals and groups of different ages and genders.

It has a certain reference role in the selection of athletes and the comprehensive evaluation of students' physique in oxygen metabolism projects. It is calculated as follows: spirometry and body weight. Units of measurement: milliliters (ml) for lung capacity, kilograms (kg) for body weight.

Lung capacity varies by sex and age, with males significantly higher than females. Before the age of 20, the lung capacity gradually increases with age, and the increase is not obvious after the age of 20. The lung capacity is about 3,500,4,000 milliliters for adult men and 2,500,3,000 milliliters for adult women.

Lung capacity depends primarily on how relaxed the chest wall expands and contracts.

Lung capacity declines with age, by 9% to 27% every 10 years, but people who have been physically active for a long time can still maintain normal lung capacity.

Once the body needs a large amount of oxygen consumption (such as long-term study, work, strenuous exercise), there will be a serious shortage of oxygen, resulting in headaches, dizziness, chest tightness, malaise, poor concentration, memory loss, insomnia and other adverse reactions, which will not only affect study and work, but also cause many irreparable losses to physical health.
