Mucus is a thick white liquid secreted by mucus membranes present inside the body. A thin layer of mucus normally covers the epithelial lining of airways.
Mucus secreting cells are present along the epithelial lining of airways as well as the intestines. These mucus secreting cells are called Goblet Cells.
Mucus along with cilia (hair-like projections inside airways) is responsible for the protection of airways by trapping microbes, pollens, and other irritants, and preventing them from entering into the lungs. It also moisturizes the inhaled air, thereby preventing dryness of airways.
Mucus production is increased on exposure to allergens, irritants, and microbes. Coughing is another protective mechanism of our respiratory system. Coughing helps to expel out dust and excess mucus.
Therefore, cough and mucus production is an indicator that your body is responding positively to stimuli. A cough and mucus together prevent smoke, dust, irritants, and microbes from reaching the lungs.
White mucus is commonly seen in apparently healthy individuals who catch a cold or when they suffer from hay-fever. In cases of common cold, mucus may be white and runny. This indicates a catarrhal inflammation of the airways. It is usually self-limiting and requires only supportive care.
However, if the mucus is white but thick, it suggests that a person has a certain degree of chest congestion, such as bronchitis. It may also be present in persons who are cigarette smokers or those who frequently come in contact with air pollution or irritants.
Avoid taking such as very oily and spicy food, curd and other dairy products. Alcohol and smoking must also be curbed as these increase mucus production.
It is advisable to cover your mouth and nose while coughing or sneezing. Actually, the infection is fairly contagious and can affect other individuals too. Also, make sure to blow your nose as and when required, as this will help you release mucus from your nose and sinuses.
In spite of the various ways, by which one can control coughing up of white foamy mucus at home, it is equally necessary to visit a qualified physician to get better and quicker relief from your symptoms. These home remedies will aid in faster recovery and are not a substitute for proper therapy.
