"Understanding the Link Between Vitamin Deficiency and Feeling Cold"

Feeling cold may be due to a deficiency in certain vitamins such as B9, B12, or iron, leading to anemia and reduced red blood cell count. Symptoms of these deficiencies include cold sensitivity, fatigue, and shortness of breath. It's important to get tested for deficiencies and not self-diagnose, as other conditions like diabetes or hypothyroidism could also cause cold sensitivity. Replenishing nutrient levels or addressing underlying conditions can help alleviate excessive cold sensitivity.
