Asthma and Allergies
Most of the time, where asthma exists, so do allergies. Asthma is a lung condition that causes breathing difficulties. Asthma is divided into several types, but in this article we are going to talk about allergic asthma.
According to the records of the American Academy of Allergy, Asthma and Immunology, half of all Americans are suffering from allergic asthma to greater or lesser degrees. As its name indicates, it is a type of allergy-triggered asthma. These allergens can be pollen, mold spores, animal hair and so on.
As we all know, we take air into our body when we breathe. Air will go through our nose and windpipe and finally reach the bronchial tubes. At the bottom of these tubes are alveoli. They are small air sacs delivering oxygen from the air into blood and gathering carbon dioxide. Normal people can carry out this simple breathing process naturally, but if you have asthma, you can’t breathe freely.
But how and why does asthma happen?
Well, when we breathe normally and freely, the bands of muscle surrounding airways are relaxed. When allergens attack, the bands get tightened, making airways narrow, which is called a “bronchospasm.” Also, when cells in airways produce more mucus than normal, the airway lining will become thicker and swollen. Narrowed airways take in less air each time, and so people can’t get enough.
While some people suffer every day, others go long periods without symptoms. Usually, there are four types of asthma symptoms: 1. Coughing a lot, especially at night; 2. Shortness of breath; 3. Wheezing; 4. Feeling tightness, pain or pressure in the chest.
Many researchers have found that using a suitable air purifier for the home is a great way to relieve the effects of asthma and allergies.
Symptoms vary, which means that a person may only have some of the typical symptoms. Or at different times, varied symptoms may occur. And in separate episodes, the symptoms can be mild or very severe. In mild asthma episodes, narrowed airways will become normal in a few hours, or only minutes. Severe episodes are relatively rare and often last longer. Medical help always plays a very important part in treating mild attacks or preventing severe ones.
Asthma may seem horrible and so sudden when it happens, but there are always ways to avoid its worst consequences. To prevent an asthma attack, it is important for us to recognize early warning signs. Here are six key ones:
6 Signs of Asthma
- You cough a lot, and it is especially frequent at night.
- You have shortness of breath or lose your breath easily.
- You feel extremely tired when you participate in sports, and you will wheeze, cough or have shortness of breath.
- You have difficulty sleeping.
- Your peak expiratory flow decreases or changes.
- You have symptoms of a cold, or you have some other upper respiratory infections as well as allergies.
If any of these happens to you, you should see the doctor as soon as possible before it becomes severe. And you may also need a suitable air purifier for allergies.
