Effective Strategies to Relieve Sinus Congestion

The paranasal sinuses are rich vascular cavities through which air passes on its way to the lungs, serving as a defense mechanism for the respiratory system. Located on both sides of the nose, the maxillary sinuses sit in the cheekbones, while other sinuses are positioned within the frontal and ethmoid bones near the eyes. These cavities are lined with ridged tissues that help humidify, warm, and filter inhaled air, removing bacteria, viruses, and allergens. When these pathogens or particles invade, white blood cells rush in to fight the infection, leading to swelling and nasal blockage.
