Cover your Core

When the human body is warm, it readily releases blood to the extremities. When your core becomes cold, the body’s natural defense is to stop sending blood to the extremities keeping it for vital organs. Therefore one of the best solutions for cold hands and feet is to increase and maintain your core temperature.
