Some parents are particularly concerned about their patients’ sleep: how well do they sleep? Are you moving? Do you have dreams? Do you talk in your sleep? How many hours of sleep? I’m afraid that if I don’t sleep well, I’ll have a relapse. In fact, these are all misconceptions! Sleep is a function that the body automatically regulates itself. There are six cycles of sleep per night, each lasting 45 to 90 minutes. First is the “non-eye movement period (NREM)”, from shallow to deep, and then from deep to shallow. Then enter the “rapid eye movement period (REM)”, when the whole body muscles relax, although the eyes are closed, but in the rapid rotation; if you wake him up, he will tell you are dreaming. If not wake up, and enter the second cycle; …… 8 hours, a total of 6 to 7 cycles, a total of 6 to 7 times dreaming. I always tell the joke: only dead people don’t dream! During NREM, growth hormone is secreted in large quantities, so children who sleep well and deeply grow taller. During the sleep period, some children’s limbs will twitch a little; some children will grind their teeth; some children will snore; some children will talk in their sleep; some children will have nightmares (nightmares). These are all normal phenomena, no need to be nervous or intervene, in fact it is impossible to intervene. A good night’s sleep is not the cause of psychosis, but may be a symptomatic manifestation of psychosis. Poor sleep does not lead to the onset of illness; with the onset of illness, it is possible to have poor sleep. Just as pneumonia can cough, but it is not the cough that causes pneumonia. What does ‘insomnia’ mean? This means that the patient wants to sleep, but cannot sleep, tossing and turning, feeling uncomfortable, this is ‘difficulty sleeping’; some patients can fall asleep, but wake up in the middle of the night, can no longer sleep, sitting and waiting for dawn, this is ‘early awakening’. These cases of insomnia are often symptoms of depression. People with OCD often have a set of compulsive actions or rituals before going to sleep, or have repeated obsessive thoughts; also causing them insomnia. Of course, normal people who are not depressed or OCD can sometimes have insomnia. When schizophrenia is onset, they don’t have insomnia. They ‘don’t want to sleep’; they don’t ‘want to sleep but can’t’, so it’s not ‘insomnia’. This is the essential difference! They don’t want to sleep, do all kinds of inexplicable things, listen to hallucinations, and think about nonsense things. When some patients are hospitalized, doctors often give them clonazepam every night for the convenience of management, so that they will sleep well and will not make any noise and will not go back to him. It is not known that this has, caused the patient’s dependence on clonazepam (addiction); so, once they do not take clonazepam, they also have insomnia, ‘want to sleep but can not sleep’. This is also the case with those who take clonazepam. Those who take other antipsychotics are better off when they stop taking them and do not have this condition. In any case, parents should not worry about how their schizophrenic patients sleep during the treatment period, as long as the medication is adequate; you can sleep in peace! If it is ‘bipolar’, which is manic-depressive, then during the manic phase, the patient will feel that they ‘don’t need sleep’ and they feel very energetic and don’t need to sleep, and that is not ‘insomnia ‘!
