Understanding Chronic Obstructive Pulmonary Disease Chronic obstructive pulmonary disease,
2
or COPD, is a lung disease that makes it difficult to breathe.
3
COPD is a long -term disease that often gets worse over time
4
and is characterized by inflammation and severe limitation of airflow in and out of the lungs.
5
COPD is an umbrella term used to describe a group of breathing conditions, the most common being chronic bronchitis and emphysema.
6
Many people living with COPD may have both emphysema and chronic bronchitis.
7
A few people have both asthma and COPD.
8
Cigarette smoking is the leading cause of COPD.
9
Long -term exposure to secondhand smoke or irritants such as air pollution, dust, or workplace fumes, and biomass exposure,
10
such as wood smoke, can also contribute to COPD.
11
An uncommon genetic disorder called alpha -1 antitrypsin deficiency is sometimes associated with COPD.
12
Although respiratory infections such as influenza and pneumonia do not cause COPD, they can make people with COPD very sick.
13
Therefore, it is very important to keep these vaccinations up to date.
14
At first, COPD may cause no symptoms or only mild symptoms.
15
As the disease progresses, common symptoms include shortness of breath, wheezing, and chest tightness, especially with exercise,
16
and an ongoing cough, often with a lot of mucus.
17
As COPD symptoms worsen, breathing requires much more energy, and it can get harder to exercise or do routine activities,
18
like getting dressed or climbing stairs.
19
This may lead to fatigue, weight loss, and muscle loss.
20
People with COPD can experience a variety of symptoms.
21
Different stages of COPD range from mild to moderate to severe.
22
In normal functioning lungs, when air is inhaled, it travels down the windpipe and into the airways, or bronchial tubes of the lungs.
23
Inside the lungs, the airways branch out into smaller and smaller tubes called bronchioles that are rich in blood supply.
24
At the end of these tubes are billions of tiny air sacs called alveoli.
25
Normally, the walls of the airways and air sacs are elastic and flexible in nature.
26
Inhaling causes each air sac to fill with air.
27
Exhaling causes each air sac to deflate.
28
Efficient uptake of air into the lungs provides oxygen to the blood, which is then carried to all parts of the body.
29
In COPD, however, the airways become thick and inflamed, and they produce more mucus than usual.
30
This mucus can clog the airways and makes it hard to breathe.
31
In COPD, the walls of the air sacs in the lungs are damaged and lose their elastic quality.
32
The air sacs get floppy, broken, and lose their shape.
33
As the air spaces get larger, air gets trapped, and there are fewer air sacs to supply oxygen to the blood.
34
Because air is trapped in these air sacs, it is difficult for lungs with COPD to deflate like normal lungs.
35
This trapped air makes it harder to get fresh air into the lungs and makes breathing more difficult.
36
COPD is the third leading cause of death in the United States and affects more than 13 .5 million Americans.
37
It is predominantly diagnosed in middle -aged individuals older than 40 years and is present in both women and men.
38
Although COPD is more common in men, more women die from this disease each year than men.
39
The rate of COPD continues to increase worldwide due to smoking and worsening air pollution.
40
While there is no cure for COPD, you can take steps to feel better, stay more active, and slow disease progression.
41
COPD can be managed by consulting early with your health care provider, seeking diagnosis and intervention therapies,
42
and adopting lifestyle changes that include quitting smoking, pulmonary rehabilitation, healthy eating and exercise,
43
and maintaining a positive outlook.

¿Qué es la Técnica de Shadowing?

Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
