Having cold extremities such as hands and legs. Getting cold in winter is not the reason to panic. However, if you’re having problems with the flow of blood, this issue may arise at any season. Our brain automatically sends the blood to the places where it is needed. As far as our hands and feet are too far from the center of the body, they tend to receive less blood sometimes. Without a stable stream of blood, we start feeling cold. Iron supplements are a good way to solve the problems of cold extremities.
