Coughing is a natural reflex that plays a crucial role in clearing excess mucus from our airways. Learn more about excess mucus and how the body naturally works to expel it when you are sick.
What is Mucus?
Mucus is a slimy and viscous substance produced by specialized cells in the body called goblet cells. It is found in various parts of the body, including the respiratory tract, digestive system, and reproductive organs. Mucus serves important functions in maintaining the body's health. It acts as a protective barrier, trapping foreign particles, such as dust, bacteria, and viruses, and preventing them from entering deeper into the body (Voynow & Rubin, 2009).
Mucus also moisturizes and lubricates tissues, facilitating the smooth movement of organs and preventing them from drying out. Additionally, mucus contains antibodies and enzymes that help fight infections and aid in the overall functioning of different body systems.
How Does Coughing Work to Get Rid of Excess Mucus?
Cough (or irritant) receptors are scattered throughout your airways. When they get stimulated (by irritants like dust or allergens or triggered by an accumulation of excess mucus), they send a signal to the cough center in the brain (Nadel, 2013).
Your brain processes this information and then tells certain respiratory muscles to rapidly contract, which results in a cough.
Coughing drives fast-moving air from the lungs, which causes your airways to vibrate. This vibration loosens the mucus that’s stuck to the mucus membranes in your airways. Coughing propels this mucus upwards and out of your airway.
While you have the power to control your cough (for example, when you cough on purpose), an involuntary cough has reflexive power, meaning it will happen even when you don’t want it to, like when you’re sick with a respiratory infection.
What Illnesses Typically Have Excess Mucus?
Certain illnesses can lead to the production of excess mucus in the body. Respiratory tract infections, such as the common cold, flu, and bronchitis, are common culprits. These viral or bacterial infections can cause inflammation in the airways, leading to an overproduction of mucus as a defensive response. Conditions like sinusitis and allergies can also contribute to excessive mucus production.
Chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD) are characterized by persistent inflammation and mucus hypersecretion. In these conditions, the airways become sensitive to triggers, resulting in excessive mucus production and narrowing of the air passages.
How to Help Your Body Be Better at Coughing Up Mucus
When you’re sick and have a productive cough to help expel excess mucus, you may find you need a little help. Many Mucinex® products contain the active ingredient guaifenesin, which is an expectorant that helps to thin excess mucus, making coughing up mucus easier and, in turn, making coughs more productive. Some Mucinex® products that contain guaifenesin are:
- Maximum Strength Mucinex® DM Extended-Release Bi-Layer Tablets
- Maximum Strength Sinus-Max® Pressure, Pain, and Cough Liquid Gels
- Maximum Strength Sinus-Max® Pressure, Pain, and Cough Caplets
- Maximum Strength Sinus-Max® Severe Congestion and Pain Liquid Gels
- Maximum Strength Mucinex® Extended-Release Bi-Layer Tablets
By using these over-the-counter medications containing guaifenesin from Mucinex®, you may experience a noticeable increase in the expulsion of excess mucus during coughing.
It is important to adhere to the medication instructions for appropriate usage and consult your doctor if your condition worsens or if you experience new or severe symptoms. Your healthcare provider is the best resource to provide personalized guidance and ensure the most effective management of your respiratory condition.
Final Thoughts
In conclusion, coughing up mucus is a natural mechanism that helps to clear the airways and maintain respiratory health. Understanding the role of coughing and the significance of mucus in our bodies can assist in recognizing the symptoms and addressing respiratory conditions effectively.
Whether it's a cold, respiratory infection, or allergies, excess mucus can cause discomfort and hinder proper breathing. Over-the-counter medications like Mucinex®, containing guaifenesin, can aid in thinning mucus, making it easier to cough up. By managing mucus and supporting the body's natural defense mechanisms, you may experience faster symptom relief.
