Dampness and heatiness as body-language
A Chinese friend may say they have heatiness after eating fried food, or dampness during humid weather. The words are compact explanations of how the body feels in context.
How to frame it
Use these terms as windows into Chinese body vocabulary. They help people talk about patterns, but they should not be used to diagnose readers.
A careful explanation can show what people mean, when they say it, what foods they associate with it, and why the vocabulary matters culturally.
Required safety note
If a reader has persistent symptoms or serious discomfort, they should seek qualified professional care.
