Cold hands and feet may be caused by weak yang qi, insufficient qi and blood, qi stagnation (obstruction of qi movement), and wind-cold. When yang qi is weak, the warming effect on the body is weakened, and symptoms such as cold hands and feet, warm limbs, loose stools, undigested food in the stool, and fatigue (mental exhaustion and physical weakness) may occur. When qi and blood are weak, qi and blood cannot nourish and warm the body, resulting in warmth in the hands and feet, dizziness, tinnitus, palpitations (rapid heartbeat, often accompanied by panic), shortness of breath, and yellowish color (yellowish and lusterless). Qi stagnation, yang qi stagnation, poor functioning, can not reach the four end of the hands and feet cool, accompanied by emotional upset, chest tightness, pharynx, such as obstruction and other symptoms. Cold hands and feet may appear when there is wind-cold, but the body may not be cold when there is a light sense of evil and a light damage to the positive qi. Seek medical advice if you feel unwell.
