De Medicina

5 Nor indeed is it only those who are troubled by a weakness of the head that find the use of cold water beneficial, but also those who suffer with persistent running from the eyes, choked nostrils and running from the nose, and tonsillar maladies. In these cases, not only is the head to be douched every day, but also the face bathed with abundance of cold water; especially should this be carried out by all those benefited by it, whenever the south wind renders the weather more oppressive. And whereas

after dinner either wrangling or mental worry is injurious to everybody, it is especially so to those who are disposed to pains in the head or windpipe, or to other forms of oral affections. Choked nostrils and running from the nose can be also avoided, or minimized, if one who is liable to these makes as little change as possible in respect to residence and water; if he protects the head, that it may not be scorched by the sun, or be chilled by a passing cloud; if the head be shaved after digestion and the stomach empty; if there be no reading or writing after a meal.
