Nasal mucus, often overlooked, plays a vital role in our health. It traps dust, pollen, and bacteria, keeping our respiratory system clean. Without it, we'd be more prone to infections and allergies. The color and consistency of mucus can tell us a lot about our health. Clear mucus is normal, while yellow or green can indicate an infection.
