Spring is the season when the body’s qi and blood rise, and everything revives, just like seeds sprouting. According to statistics, the recurrence rate of mental illness accounts for more than 70% of the year from March to May. The spring season is characterized by frequent alternating activities of cold and warm air, sometimes warm and sometimes cold, and great changes in temperature, air pressure, airflow and temperature. Medical meteorological research suggests that this is due to the high sensitivity of psychiatric patients to changes in temperature, air pressure, air humidity, airflow and other meteorological elements. Among the four seasons of the year, the climate in spring is unpredictable; as the folk proverb says, “The monkey face in spring changes three times a day”. Or wind and sunshine, spring is bright; or cloudy and rainy, cold. Therefore, the folk have “spring cold through the bones cold” and “spring cold freezing cattle” saying. Research shows that when the temperature is as high as 26 to 30 ℃, air humidity is greater than 70%, the human spirit is easy to fatigue, slow thinking, irritable, easily irritated; when the temperature drops below 5 ℃, the weather is gloomy, the human spirit often fall into a state of overwhelm, frustration or depression, manifested as a trance, restlessness, etc.. Spring pressure is low, people feel more depressed, surrounding objects in the spring will emit a kind of infrasound affect the human endocrine system, resulting in endocrine disorders, while the human body nerve cells in the spring is relatively active, the brain is more sensitive to external stimuli, prone to mood swings, which leads to abnormalities in human cognition, emotion, behavior and will. Patients with mental illness are more sensitive to these weather elements and changes, making it easy for old illnesses to relapse and worsen or deteriorate. Early clinical symptoms are: i. Sleep and memory disorders. Psychiatric patients appear to have insomnia with no obvious cause, experience no pain, and do not actively seek medical attention. In some cases, even if they stay awake all night, they are still not tired the next day. Some patients feel overly energetic. However, careful observation may reveal inattention, memory loss, scattered thought content, disorganized speech, and increased movements. Second, personality change. People who are enthusiastic, optimistic, sociable and outgoing suddenly become silent and lonely, and ignore or distant from people they used to get along with. Third, emotional abnormalities. Mood changes in psychiatric patients are often unexplained, and even small “stimuli” can cause large “reactions”. For example, manic patients are often manifested as a day-to-day joyful, over-enthusiastic. Patients with depression are depressed and depressed. Other patients hear the news of misfortune but laugh, and learn of happy events but sigh. Or indifferent to what is happening since the side, no emotional reaction. Fourth, excessive paranoia. These people are particularly sensitive to the words and actions of people around them. If they hear someone talking, they suspect that they are talking about themselves; even if someone coughs, they suspect that it is directed at them. The difference between this kind of paranoia and normal people’s paranoia is that although the facts are confirmed and denied, the patient is still convinced and cannot be convinced. V. Abnormal movements and behaviors. For example, patients with delusions of victimization often have sudden aggressive behavior towards delusional objects. Manic patients with high mood may have excessive decoration, or “generous help” or nosy performance. Depressed depressed patients often sit and stand still or are silent. Patients with hallucinations often listen sideways or react with corresponding behaviors, such as yelling into the air. Ways to prevent recurrence of mental illness in spring: First, if irritability, anxiety and other emotions, realize that this is the human body seasonal mood fluctuations, not because of increased work difficulty or workload, to be fully prepared. Second, pay attention to reasonable rest and rest, grasp the time and progress of work, appropriate to reduce the workload, more rest. Third, go out more and get closer to nature. You can ask friends to go out to fly kites; you can also walk to work or school; or ask friends to ride bicycles to the countryside on rest days to breathe fresh air or dig wild vegetables; or raise some green plants indoors or on your desk and water them carefully every day; and do some physical exercise. Fourth, supervise psychiatric patients to strictly comply with medical advice, adhere to the medication, do not stop taking medication without authorization. The psychiatric patients at home should be supervised and taken care of to prevent accidents. If the above symptoms continue to worsen or even appear suicidal or aggressive behavior, you should go to a psychiatric hospital for further examination and seek help from a psychiatrist.
