Maintaining a strong, resilient immune system has never been so important. With our increased susceptibility to viruses in the winter months, now is the best time to ensure your supply of immunity boosting supplements is at hand when you need them most.
Dr. Joseph Ladapo has now issued a state-wide public service announcement in support of common-sense COVID prevention strategies such as optimizing your vitamin D, staying active, eating nutrient-dense foods and boosting your immune system with supplements such as vitamin C, quercetin and zinc.
Dr. Joseph Ladapo was appointed Florida surgeon general and secretary of the Florida Department of Health by Gov. Ron DeSantis September 21, 2021.
How does winter affect my immunity?
Reduced Vitamin D Levels
Due to the reduced sun exposure, many people get less vitamin D during the winter months. With vitamin D playing an essential role in maintaining the immune system, lower levels can decrease your body’s response to viruses. We recommend choosing a suitable vitamin D supplement and encourage a diet of foods rich in vitamin D.
Studies have found that being exposed to lower temperatures can result in a decreased immune response to viruses. There is also evidence to suggest that certain viruses are more active and reproduce faster in the lower-temperature nasal passages brought on by the cold air.
Blood Vessel Narrowing
Breathing in cold and dry air causes the blood vessels in the upper respiratory tract to narrow to conserve heat. This may prevent white blood cells from reaching the mucous membrane, making it more difficult for the body to fight off viruses.
