Some signs of heat, cold, damp and dryness

As-Suyuti in "Medicine of the Prophet" said, "[darker shades of] hair and a [darker shades of skin] are signs of heat: the opposite a sign of cold. Similarly, a fat body or a thin body. An excess of flesh is a sign of heat combined with damp. Excess of fat is a sign of cold combined with damp. In the same way, excessive desire for sleep is a sign of damp, whereas a diminished desire is a sign of dryness. A moderate desire is the sign of a balanced temperament.”
