”Cauliflower is yellow and the foolish son is busy”. How to explain? Seasons and schizophrenia Xiao Zhang, 25 years old, developed a mental abnormality in March last year, manifested as heavy suspicion, believing that the local Public Security Bureau has installed high-tech surveillance equipment everywhere he goes to monitor and persecute himself, therefore, he does not dare to go out to work, at home to close all the curtains, and people at home to speak, then signaled to speak softly so as not to be heard. Sleep is not good and it is difficult to sleep. Sometimes when eating, but also to see the family eat before eating, drink water must drink unopened mineral water, once opened, then can not leave their hands, or they have to throw away. And often call 110 to call the police to come to their rescue. He has a big temper, becomes withdrawn and does not interact with people. After a hospital examination, he was diagnosed with schizophrenia and was treated with antipsychotic drugs. The disease was soon under control, his symptoms disappeared, he was able to go outside and do things, and his interactions with people returned to normal, and he kept taking his medication, and his family was happy. However, just after the Spring Festival this year, his family noticed a change in his behavior, becoming silent, sometimes saying some inexplicable things, not sleeping well, and often getting up at night to go to the toilet. He was also in a bad mood and sullen. When he came home from work, he went straight to the computer. Sometimes he was alone and dazed, and ate very little. After the doctor’s examination, it was found that his psychiatric symptoms appeared to be a relapse of the disease. Xiao Zhang’s relatives are very confused, there is no some mental stimulation triggers outside, the work is also smooth, has been insisting on taking medication, why Xiao Zhang’s mental illness has relapsed? There is a close relationship between seasons and diseases. There is a Chinese saying that “cauliflower is yellow, the fool is busy”, meaning that patients with a history of mental disorders in the spring are prone to relapse or aggravation of their illness. According to medical data, March to May is the worst and most unstable season for people, and it is also the time when the relapse rate of mental illness is extremely high. According to relevant statistics, the relapse rate of mental illness during this time accounts for about 70% of the annual relapse rate, while April-May, when rape flowers are in full bloom, is the peak period for psychotic episodes. Why is early spring the beginning of a good period for mental illness? Possible reasons are: Meteorologically, the high variability of sunlight and temperature in spring tends to affect people’s moods. From the cold winter into the warm weather, so that the human metabolism into a period of high, which also easily cause the human body’s internal environment and endocrine activity changes, easy to first mental illness onset; or once had a mental illness has been in remission (clinically cured) is easy to relapse at this time; or still continue treatment but the symptoms have been less severe at this time aggravated. Psychotic episodes have precursors According to statistics, there are currently about 16 million adults with mental disorders in China. How to grasp the impact of seasons on mental illness and reduce the relapse rate of mental illness is a very important topic. Psychiatric patients will have some aura symptoms before their relapse: 1. Sleep disorder For example, there are difficulties in falling asleep, early awakening, shallow sleep and easy waking, nightmares, etc. Mood disorders such as unexplained anxiety, panic, irritability, restlessness, fidgeting or depression. Laughing or crying for no reason. 3.Thinking disorder Talking in an incomprehensible way, speaking without a theme; suspicious, etc. 4.Behavioral disorders Poor interpersonal relationship, trouble in work, study and family activities; poor academic performance, failure to complete work tasks, difficulty in social activities and interaction, oligophrenia and inattention; lack of initiative; drowsiness; talking to oneself; laziness, personal hygiene needs supervision. Therefore, during the good season of March-May, patients who have suffered from mental illness and are taking medication, especially those who have had their first or recurring psychosis in the good season, should be on high alert. Whenever there are signs of abnormalities such as continuous insomnia, inappropriate speech and behavior, it is important to consult a doctor in time to control the disease in a “nascent state” by adjusting the dosage and type of medication. When they encounter various stressful events during the season, they may want to go to a professional hospital for professional psychological intervention as early as possible to improve their coping ability, maintain a good state of mind, and enhance their mental health. It is of positive and important significance to enhance the ability to resist mental illness and prevent its onset.
