Mucus, often regarded as an unwelcome visitor during illness, plays a crucial role in the body's defense mechanisms. It acts as a barrier, trapping debris, allergens, viruses, and bacteria that enter the airways. While extra mucus production is typically associated with respiratory infections, it serves as a protective measure to wash pathogens away. This article delves into why your body produces mucus, how it functions, and what you can do to manage it when you're sick.
Your body continuously produces mucus as a natural defense mechanism, even when you are not under the weather. “During the course of a day, you’re swallowing plenty of mucus,” states Dr. Kanwar Kelley. Mucus acts as a lubricant and barrier between you and the outside world, filtering what you breathe in. Dr. Linda Dahl emphasizes its significance, stating, “It is a lubricant and also provides a barrier between you and the outside world as a first line of defense by filtering what you breathe in.”
When respiratory infections strike, mucus production ramps up significantly. This increased production is your immune system's way of kicking into high gear to defend your body. The extra mucus not only traps pathogens but also creates a flow to help wash them away from your system. Dr. Kanwar Kelley explains, “It immobilizes those things and helps to prevent you from getting infected.”
Mucus primarily consists of water and large molecules known as glycoproteins, which give it its thick and sticky consistency. According to Dr. Rakesh Chandra, “It is mainly a combination of water and large molecules called glycoproteins, which are a sort of hybrid between sugars and proteins that make the mucus [thick] and a bit sticky.” Additionally, mucus contains salts and molecules that form part of our immune defense system.
Dehydration can exacerbate mucus thickness, making it more challenging to clear. Filimonov notes, “Being dehydrated can make the mucus more thick, and difficult to clear.” To alleviate this, over-the-counter medications such as antihistamines and pseudoephedrine can help reduce mucus production. Moreover, saline sprays can effectively loosen mucus, facilitating its movement out of the sinuses.
Nasal irrigation tools like neti pots can also be beneficial in washing out mucus that has trapped bacteria and viruses. Dr. Ramsadeen advises, “You should spit it out to clear out the thicker mucus and open up the drainage pathways of your nose and sinuses.” Sometimes, expelling mucus can provide immediate relief, as highlighted by Dr. Kanwar Kelley: “Sometimes spitting it out can make you feel better in the moment.”
While producing more mucus when sick is normal, persistent symptoms for more than a week warrant medical attention. Excessive mucus production might indicate an underlying issue that requires professional evaluation. If one continuously produces more mucus than usual or if symptoms persist beyond a week, consulting a doctor is advisable.
