You are suffering from one of the most common health problems faced by people who have to work in dusty environments. As your doctor has pointed out, inhaling dust and pollution can cause deterioration in your lung functions similar to that observed in regular smokers. You may also have experienced secondary symptoms such as a persistent cough and shortness of breath. This occurs when your environment damages the cilia of the lungs. Under normal conditions, these cilia (tiny hair-like organs) constantly filter out toxins from the air you breathe. However, in a heavily polluted environment, the cilia are damaged and can no longer perform their function. You then develop a constant cough as your lungs try to purge out the damaging pollutants. In time, your lungs get congested with foreign matter that needs to be expelled. Without adequate treatment, you could also be at the risk of serious conditions like bronchitis, emphysema, or pneumonia.
The first step you can take is to purchase a mask with an effective air filter. You may not be able to choose your work environment, but you sure can reduce the risk! You should also consider some remedies that will help your lungs cleanse themselves. If you smoke (though you have not said so) please quit immediately and avoid second-hand smoke. Include some natural decongestants in your diet. For example, menthol helps to thin mucous and is a good decongestant. Many herbalists believe that mullein tea acts as a great lung cleanser, since mullein has been proven to show decongestant properties. Ginger is another natural ingredient that works wonders for congestion. It also has strong antiseptic properties. Boil some crushed garlic in a cup of water for at least 10 minutes, strain and drink the liquid while hot. You could add a teaspoon of honey, which helps to boost your body’s immunity and promotes the natural healing process. You can even try some steam therapy; put 2-3 drops of tea tree oil or eucalyptus oil in a bowl of hot water and inhale the steam. This ensures that the health benefits from these essential oils get directly to the affected parts of your lungs.
However, you should keep in mind that a full recovery is a long-term prospect that could take years. Start to include regular exercise in your lifestyle and spend time in non-polluted, fresh air. Exercise can help your lungs recover from the damage they have suffered and will also help build your endurance and immunity.
