The Hidden Link Between Frequent Colds and Vitamin D

If you feel like you’re constantly fighting off colds and other bugs, the reason might be a hidden deficiency in your system. A prominent doctor explains the crucial link between a robust immune system and adequate levels of Vitamin D, the “sunshine vitamin.”
The expert clarifies that Vitamin D is a powerful modulator of the immune system. It functions as a hormone that helps to activate our body’s T-cells, which are the frontline soldiers that identify and destroy invading pathogens. When Vitamin D levels are low, this response is weakened.
This is why one of the classic, yet often overlooked, signs of a deficiency is frequent infections. If you seem to catch every illness that goes around the office or your home, it could be a signal that your immune defenses are not operating at full strength.
Unfortunately, it’s very difficult to get enough of this immune-boosting nutrient from food alone. The physician notes that dietary sources are scarce, and even a healthy diet is unlikely to provide the amount needed for optimal immune function.
The most effective way to strengthen your defenses is through natural sun exposure. The doctor recommends 10 to 30 minutes of midday sun on your arms and legs. This can generate up to 2,000 IU of Vitamin D, providing your immune system with the hormonal support it needs to keep you healthy.
