## Resource

Severe vitamin D deficiency is linked to a sharply higher risk of hospitalization for respiratory infections such as bronchitis and pneumonia, turning common illnesses into serious medical events Adults with the lowest vitamin D levels face worse outcomes after pneumonia, including a much higher risk of dying months after hospital discharge, even when initial illness appears mild Higher vitamin D levels are associated with fewer everyday respiratory infections like colds and flu, reducing how often illness disrupts work, sleep, and daily life Vitamin D deficiency is widespread, often silent, and driven by limited sunlight exposure and modern indoor lifestyles, making it a correctable risk factor rather than an unavoidable one Combining systemic immune support from vitamin D with early, localized airway defenses helps stop respiratory infections from gaining momentum before they escalate
