Coughing, sneezing, and mucus buildup in the chest and throat are common signs of illness that can cause discomfort and difficulty breathing. Phlegm, a thick secretion from the respiratory system, traps dust, allergens, and germs. However, excess mucus may develop due to colds, allergies, or infections. Natural ways to manage mucus include staying well-hydrated, gargling with salt water, inhaling steam, applying a warm compress, or drinking tea with honey and lemon. Using a humidifier and nasal irrigation can also provide relief. It’s best to avoid irritants such as smoke and chemicals, as well as limiting dairy and sugar intake. If symptoms persist or worsen, consult a healthcare professional for further evaluation.
