Keep feet warm and head cool.
A cool mouth and warm feet live long (Br.).
Feed a cold and starve a fever (Am.).
Keep the bowels open, the head cool, and the feet warm and a fig for the doctors (Br.)
Tête froide ventre libre pieds chauds.
Держи голову в холоде, живот в голоде, а ноги в тепле.
Den Kopf halt kühl, die Füße warm, das macht den besten Doktor arm.
Ayağını sıcak tut, başını serin.
