When a person has suffered from exposure to great heat, Rhases recommends
rest, the tepid bath, and fruits and food of a cooling and moistening
nature. When there is headach, he directs the head to be anointed with
oil of roses and vinegar. (Ad Mansor. vi, i.)
Averrhoes recommends a person who has suffered from exposure to the sun
to be put into a tepid bath, and rubbed afterwards with refrigerant oils.
