insomnia

Inability to sleep, in the absence of external impediments, such as noise, a bright light, etc., during the period when sleep should normally occur; may vary in degree from restlessness or disturbed slumber to a curtailment of the normal length of sleep or to absolute wakefulness. SYN: sleeplessness. [L. fr. in- priv. + somnus, sleep]
- conditioned i. a form of i. resulting from conditioned behaviors that are incompatible with sleep, e.g., each time a person walks into his bedroom, his first thought is that he is not going to be able to sleep.
- subjective i. a condition characterized by the subjective experience of greatly reduced sleep, in the context of relatively normal physiologic measures of sleep.
