How it's used
Refers to a concept in traditional Chinese medicine where excessive internal heat manifests as irritability, mouth ulcers, or insomnia. It is frequently used metaphorically to describe someone who is visibly stressed, impatient, or prone to sudden outbursts of anger. People often suggest drinking cooling herbal tea or avoiding fried foods to alleviate this state.
Examples
Have you been having a lot of internal heat lately? You're losing your temper all the time.

Common mistake
Do not confuse this with literal heart disease or cardiac issues. It describes a state of emotional and physical imbalance rather than a medical diagnosis of the heart organ itself.
