Live in rooms full of light

Avoid heavy food

Be moderate in the drinking of wine

Take massage, baths, exercise, and gymnastics

Fight insomnia with gentle rocking

or the sound of running water

Change surroundings and take long journeys

Strictly avoid frightening ideas

Indulge in cheerful conversation and amusements

Listen to music.

A. Cornelius Celsus, in De Medicina, 30 AD
