Are you hot or cold?

Many patients come to me asking whether they are “cold” or “hot” people. Coldness and heat are two principles in Chinese medicine used to differentiate between how much yin and yang individuals have. It does not refer to whether a person is hot- or cold-blooded, but about the balance of the hot yang to the cold yin.

A cold person may have a deficiency of yang or excessive yin in the body. Symptoms of cold syndrome include: An aversion to cold and preference for warmth; pale face; cold limbs; lack of thirst; clear, thin phlegm and mucus; clear and frequent urination; loose stools; pale tongue with white and moist coating; slow or tense pulse.

A hot person may have excessive yang or a deficiency of yin in the body. Symptoms of hot syndrome include: An aversion to heat and preference for coolness; preference for cold drinks when thirsty; red face and eyes; irritability; yellow, thick phlegm and mucus; bleeding or spitting up blood; nosebleeds; dark infrequent urination; constipation; red tongue with a yellow dry coating; rapid pulse.

However, when symptoms flare up, it may not be simply hot or cold, but a combination. The human body may exhibit actual or virtual “false” heat, along with actual or false cold. In today’s society, it is common to see someone with both hot and cold symptoms.

For example, a patient with a cold spleen and stomach may also have hot symptoms of fever, headache, cough and sore throat. At the same time, he has loose stools, clear urine in increased volume and cold limbs, which are symptoms of cold syndrome.

While the question seems simple, it is actually quite complicated. If the medical practitioner tells people they are “hot,” they will try to balance it with herbal “cool tea” to increase their yin. If patients told they are “cold,” they will load up on “hot” herbal supplements like ginseng to boost their yang. When individuals overdo their hot or cold foods, it affects their balance of yin and yang. Therefore a “hot” person becomes cold, a “cold” person becomes hot or they have an imbalance of hot-cold.
