Insomnia is often associated with poor sleep hygiene, such as using the bed as a place to work and live, and sleeping with the lights on. Poor sleep hygiene can disrupt the normal sleep-wake rhythm, create a false concept of sleep, and cause unnecessary bedtime excitement, which can lead to insomnia. Poor sleep hygiene is both a cause of insomnia and often a consequence of inappropriate behavior taken by insomnia patients to improve their insomnia, thus forming a vicious cycle that makes transient insomnia or short-term insomnia evolve into chronic insomnia. Clinical practice has shown that many patients with chronic insomnia are able to obtain a solution to their insomnia or get relief by improving their sleep hygiene, and can improve their prognosis.
