Mucus might seem like an unappealing substance, but it’s essential for keeping us healthy. It works as the body's "flypaper," trapping dirt, debris, and pathogens before they can reach our lungs. Every day, we produce about 1.5 quarts of mucus that sweeps into the back of the throat and is swallowed, where stomach enzymes neutralize potential threats. Besides acting as a first line of defense, mucus helps to hydrate and protect various parts of the respiratory system.

This sticky substance consists of mucins — protein structures with sugar molecules — that attract water, forming a gel that protects our airways, nasal passages, and sinuses. This hydration function is especially crucial during cold weather or when facing an infection, as mucus production increases to protect against dry air and pathogens.

Color changes in mucus can even signal what’s happening in our bodies, with colors like yellow or green indicating the presence of immune responses. Meanwhile, thick mucus may point to dehydration, making it essential to stay hydrated and maintain good indoor humidity.

To help maintain a healthy mucus balance, avoid overuse of decongestant sprays, which can lead to dependency. Instead, focus on hydration, using humidifiers, and, when necessary, natural options like saline rinses to ease congestion. Mucus, while often overlooked, plays a critical role in both capturing harmful particles and supporting respiratory health, underscoring the need to keep our respiratory systems hydrated and balanced.
