Insomnia is a subjective experience of decreased sleep quality and duration due to difficulty falling asleep or sleeping consistently, which does not meet the needs of normal physiological and physical recovery and affects normal social functioning. Behavioral therapy is preferred for insomnia, and medication is also required for severe insomnia. 1.Behavioral therapy: correct understanding of insomnia, develop good sleep habits, prevent and correct poor sleep behavior and concepts, and if necessary, psychological counseling to eliminate the concern and fear of insomnia symptoms. Such as choosing a suitable sleeping environment, reducing the time in bed, getting up immediately when you can’t sleep, developing the habit of getting up at the same time every day no matter what time you go to bed at night, and reducing or canceling daytime naps, etc. In addition, choosing a suitable sleeping posture and relaxing the body by soaking the feet before going to bed will also play an auxiliary role. In addition, avoiding too full or hungry before bedtime and reducing mood swings can also improve sleep. 2.Medication: If behavioral treatment fails, medication can be used. Commonly used drugs are benzodiazepines (diazepam, eszopiclone, etc.) and non-benzodiazepines (such as pyrazolopyrimidines, GABA receptor agonists and their reuptake inhibitors, etc.) and other drugs that help sleep (such as antidepressants). All of these medications have certain side effects and require attention to drug dependence and rebound of symptoms from discontinuation, as well as compliance with the principle of individualized and as-needed medication. To sum up, if you want to treat insomnia, you should first look for the cause of insomnia and the etiology of insomnia, so as to treat the cause, and after the behavioral treatment is ineffective, you need to choose further medication for symptomatic treatment, and remember to follow the doctor’s prescription.
