Why Do My Hands and Feet Feel Numb and Cold?

Numbness and coldness in hands and feet may be caused by anemia, vascular disorders, low blood sugar, hypotension, inadequate clothing, cervical spondylosis, and other reasons. Here are some possible explanations:

Insufficient circulating blood volume or low hemoglobin and red blood cell counts can lead to cold hands and feet.

Cold hands and feet are closely related to heart and blood vessels. When the function of the cardiovascular system is impaired, the ability of blood vessels to constrict and blood to flow back becomes weakened, resulting in poor blood circulation, especially in the fingertips. This can affect the transport of blood and cause cold hands and feet.

Food is an important source of heat for the body. When blood sugar levels are too low due to excessive dieting or hunger, it can lead to cold hands and feet.

When blood pressure is low, blood circulation is poor. During times of fatigue or physical weakness, blood pressure may drop, leading to cold hands and feet.

Thin clothing that does not provide sufficient warmth to the hands and feet, or maintaining the same posture for a long time that presses on blood vessels and nerves, can lead to coldness and numbness in the extremities.

Early symptoms of cervical spondylosis include stiffness and pain in the neck, numbness and coldness in the hands and feet, as well as headache, dizziness, and numbness and weakness in the limbs.
