Sinus health refers to the well-being of the sinus cavities, which are air-filled spaces located in the skull. These cavities help to filter and humidify the air we breathe, and they play a role in our sense of smell. Maintaining good sinus health is important to prevent issues like sinusitis, which is an inflammation or infection of the sinuses. Common factors that can affect sinus health include allergies, colds, and environmental irritants. Symptoms of sinus problems may include nasal congestion, facial pain, and headaches. Proper hydration, avoiding allergens, and using saline nasal sprays can help support healthy sinuses and reduce the risk of infections.
