Question

Quizplus · Accepted Answer

The hyperarousal model suggests that insomnia is caused by an overactive nervous system that makes it difficult for individuals to fall asleep and stay asleep. This can be due to factors such as stress, anxiety, or even genetics. Stimulant drugs including caffeine, overwork and pressure, and subclinical mood disorders can all contribute to insomnia, but they are not necessarily the underlying cause according to the hyperarousal model.
