What Are the Symptoms of Cold Blood?

Blood coldness, as the name suggests, is a manifestation of physical weakness caused by poor blood circulation in the body. Common symptoms include cold hands and feet. In traditional Chinese medicine, cold hands and feet are considered a type of "closure syndrome". The term "closure" refers to a blockage, which can be caused by factors such as cooler weather or exposure to cold, leading to coldness in the liver meridians, affecting the liver's blood-making function, resulting in insufficient yang energy in the kidneys, cold limbs, red or white hands and feet, and even a feeling of pain.

1. Hormonal changes due to menstruation and childbirth: The majority of people with symptoms of cold hands and feet are women. Hormonal changes can affect the nervous system, leading to vasoconstriction and reduced blood flow in the skin, thereby triggering coldness symptoms.

2. Circulatory disorders: Heart weakness can prevent blood supply to the extremities of the body. Anemia, caused by insufficient circulating blood volume or low hemoglobin and red blood cell count, can weaken the ability of blood vessels to constrict and blood to flow back, resulting in poor blood circulation in the extremities, especially the fingertips, which is commonly known as "poor peripheral circulation".

3. Disease factors: Diseases such as Raynaud's disease and Raynaud's phenomenon, as well as polyarteritis nodosa, are more common in young women. Thromboangiitis obliterans is more common in middle-aged men. Additionally, individuals who experience excessive mental stress, excessive psychological sensitivity, excessive worry, and frequent anxiety are also prone to cold hands and feet.

Cold hands and feet can lead to decreased menstrual flow, menstrual irregularities, and even infertility in women. During special physiological periods such as menstruation, pregnancy, and postpartum, women are more prone to experiencing cold hands and feet due to physical weakness. If not prevented in time, it can lead to poor mental state and aversion to cold. Long-term cold hands and feet can also lead to frostbite during winter. Furthermore, cold hands and feet are associated with diseases such as rheumatism and gastric disorders.
