You’ve been looking forward to your previously planned climb, but it’s hard to scramble up a rock face when no matter how much you blow your nose, your sinuses feel like they are about to burst. You feel like the yellow mucus is a signal of a sinus infection to come, but is it that simple?

Discolored mucus is a common concern when fighting what feels like a relentless battle and the only weapons are a small fortune in facial tissue and a few short naps. As you consider whether to consult your doctor about your thick colorful mucus, you wonder what makes it turn colors, and what it might mean.

What Does Mucus Do?

Mucus, often seen as nothing more than a discomfort-causing nuisance, plays a crucial role in our body’s defense system. It is the first line of protection for the body acting as a shield against germs and allergens. Composed mainly of water along with sugars, proteins, and protective molecules, mucus forms a barrier that traps harmful substances, preventing them from wreaking havoc in our respiratory system.

Some theorize that the body produces over four cups of mucus daily which is understandable considering it lines the tissues of the nose, throat, lungs, intestinal system, and even the eyeballs. Mucus safeguards from external aggressors, silently working to keep internal systems moisturized and trap, protect, and repel potential threats. If dust, allergens, and other microorganisms make it into the lungs, tiny hairlike cells, called cilia, beat together and force the contaminated mucus out. Contaminants are sneezed and coughed out, or moved to the back of the throat where they then slip down into the stomach. Defense aside, mucus also serves a more pleasant function—enhancing our sense of smell by capturing aromatic molecules and delivering them to the smell receptors high in the nose.

Does Mucus Color Mean Anything?

The color of your mucus can offer valuable insight into your body’s current state of health. Under normal circumstances, mucus appears clear and fluid. However, when it traps irritants or bacteria and viruses, its color may change. When the white blood cells in the mucus meet an undesired organism, bacteria, or allergen, they produce enzymes to help repel them. The enzymes produce a yellow or green color as they interact with foreign matter. Green and yellow snot can point to a battle, but the color alone does not mean that the battle has entered the tissues of your body. Sometimes, a change in mucus color is due to environmental factors and things that are breathed in such as dirt, dust, or pollen. Other times it is one of a group of things that signal a potential underlying issue.

Beyond color, it’s essential to pay attention to other mucosal indicators such as consistency, volume, and accompanying symptoms. Thickened mucus, coupled with congestion and sinus pressure, may suggest an infection is brewing within your respiratory tract. However, individual responses to illness vary, and not everyone will exhibit the same symptoms or mucus changes.

What Can I Do For Sinus Relief?

Remember, mucus has a job to do and it’s important we let it do its job. If you are struggling with an excess of mucus and you feel you could use some help, try these options:

  • Wet a washcloth with warm water and apply it to your face.
  • Fill a bowl with steaming water, place a towel over your head, and lean over the bowl to breathe in the steam and loosen mucus. Remember to keep your head a safe distance above the bowl.
  • Take a steaming hot shower.
  • Use a nasal saline spray or rinse to clear out mucus and ease your breathing. If making your own, only use distilled, sterile, or previously boiled water.
  • Consider over-the-counter medications. Antihistamines can help if your mucus is caused by allergies. Expectorants can thin mucus to help clear it from your chest.
  • Decongestants shrink blood vessels, so you produce less mucus. (Be careful about overusing them, as they can make the problem worse.)

(If your child is experiencing excess mucus production, avoid over-the-counter remedies as they have not been proven effective. Chest and vapor rubs can increase mucus production and can be dangerous for young children.)

It’s essential to use remedies judiciously and visit us if symptoms persist or worsen.

Will Antibiotics Help My Sinus Infection?

When it comes to treating sinus infections, the decision to prescribe antibiotics isn’t always straightforward. Most cases are caused by viruses, rendering antibiotics ineffective.

When antibiotics might be needed:

  • Difficulty breathing, shortness of breath
  • You have a high fever of 104°F or higher that isn’t improving
  • Thick discharge that is uniformly white (that is, it looks like pus)
  • The infection drags on for more than 10 days, or if it gets worse after a week
  • You see more than a hint of blood
  • Severe symptoms that do not respond to over-the-counter sinus and cold remedies

While yellow or green mucus may spark concern, it’s important to keep in mind that they are a normal part of the body’s defenses, just stay alert to any other changes in your health that may pop up. As you navigate the ups and downs of seasonal sniffles and sinus woes, remember to practice good hygiene and preventive measures to reduce your risk of falling ill. And rest assured, even if they do make it past the body’s defenses, viruses last for only a brief time.
