Insomnia is often misunderstood as simply "not being able to sleep," but this oversimplification masks the complex nature of this sleep disorder. True insomnia involves much more than occasional sleeplessness - it's a persistent pattern of sleep difficulties that can significantly impact physical health, mental well-being, and quality of life.
