Celebrated annually on November 2nd, World Vitamin D Day aims to raise awareness about vitamin D deficiency as we approach the winter months. This essential nutrient plays a crucial role in strengthening the immune system, supporting bone health, and enhancing our mood. Yet, a large part of the population does not get enough of this vital vitamin. Limited sunlight during the winter months makes vitamin D deficiency an even more prevalent issue.
Research in Türkiye shows that the prevalence of vitamin D deficiency ranges between 50% and 80%. This deficiency, identified through serum 25-hydroxyvitamin D levels, is typically measured at values below 20 ng/mL, affecting not only bone health but also weakening the immune system. Especially in the northern hemisphere, the lack of sufficient vitamin D intake during winter months can lower resistance to illnesses.
Vitamin D can be obtained through sunlight as well as from certain foods. While sources are limited, vitamin D can be found in cod liver oil, fatty fish, egg yolks, and certain plant-based foods. Supplements recommended by a doctor can also be taken when necessary. Exposing oneself to the sun for 10-15 minutes in the morning can naturally boost the body’s vitamin D production and help reduce the risk of deficiency.
This day serves as a reminder of the symptoms and health impacts of vitamin D deficiency. Persistent fatigue, muscle and bone pain, frequent infections, and depressive symptoms may indicate a lack of vitamin D. If these symptoms continue, checking vitamin D levels becomes essential.
World Vitamin D Day emphasizes the importance of getting sunlight, balanced nutrition, and taking precautions when necessary for a healthy life. Through this special day, we can take small yet impactful steps to increase our vitamin D awareness and move towards a healthier lifestyle.
