Abstract

Insomnia can be defined as the subjective feeling that an individual is not sleeping or not getting enough sleep. The important characteristic of insomnia is that it is a symptom, not a sign. The complaint comes from the insomniac himself. It derives from what a person feels, not from observations of him (Kleitman, 1963). “Those who sleep eight hours and believe they need ten consider themselves to be suffering just as much from insomnia as others who cannot get more than four or five hours sleep, but who would be satisfied with six or seven” (Kingman, 1929).
