Vitamin B12 Deficiency: The Hidden Cause Of Cold In Winter

Feeling unusually cold this winter may be linked to a vitamin B12 deficiency. This vitamin is essential for red blood cell production and oxygen transport. A lack of B12 can cause anemia, fatigue, and other symptoms. To stay warm, dress in layers, stay active, and consume B12-rich foods. Drinking warm beverages and using hot water bottles can also help regulate body temperature.
