Historically used for thousands of years as a traditional folk remedy, modern research provides evidence that the answer to 'does eating honey while sick help?' is a definitive yes, particularly for symptoms like cough and sore throat. Honey has long been a staple in home medicine cabinets for its soothing properties.

According to estimates, over one billion people worldwide have insufficient vitamin D levels, a condition that can significantly impact immune function. This widespread deficiency raises a key question for many: can low vitamin D cause a sore throat or contribute to other recurring upper respiratory issues?.

According to a 2022 study published in the *International Journal of Epidemiology*, low vitamin D levels are directly associated with higher levels of C-reactive protein, a biomarker for chronic inflammation. This connection suggests that while low vitamin D may not directly cause a runny nose, it can weaken the immune system and increase inflammatory responses that contribute to respiratory issues, such as those that produce a runny nose.
