In the four seasons of the year, the most unpredictable season of climate change is spring, when people’s spirits are easily exhausted, sluggish, irritable and easily provoked; when the weather is gloomy, people’s spirits often fall into a state of overwhelm, frustration or depression, manifested as a trance, restlessness, etc. This is a drastic change in meteorological elements can cause changes in the body’s thermoregulatory center and physiological, biochemical state and neuroendocrine system, which in turn induce the occurrence of psychosis. At the same time, the secretion of brain cells in spring is vigorous, and the unbalanced secretions produced can cause mental disorders. Moreover, in the spring, the light time starts to extend and the intensity of light increases, the secretion of melatonin from the pineal gland of the brain is suppressed, and the mood and gonadal function are relatively active, which can also trigger the occurrence of manic-depressive disorder. As relatives of psychiatric patients, they should pay attention to the following changes: 1. Sleep and thinking and speech disorders: Sleep status is the “barometer” for observing the condition of psychiatric patients, and patients with psychiatric history are preferred to have sleepless nights or sleeplessness, waking up more often, dreaming more often, and still have no tiredness the next day. However, careful observation may reveal inattention, scattered thinking, disorganized speech, and increased movement. 2, personality and mood anomalies: the original is enthusiastic, optimistic, collegial, sociable extroverted personality, suddenly become silent, lonely; calm people suddenly all day long joyful, excessive enthusiasm. If there is no special reason for the sudden occurrence of obvious personality and emotional changes, it should be taken seriously. 3, 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. This kind of pathological thinking is called paranoia. 4. Abnormal movements and behaviors: Abnormal movements and behaviors are generally easy to recognize. For example, if the person acts aggressively, talks to himself or herself, is withdrawn, smashes things, or refuses to take medication, he or she should be on high alert. For those who are suspected to have the above signs of mental abnormalities, it is recommended to go to a specialized hospital for further examination and to do the following: 1. Taking medication on time and correctly is the key to preventing relapse of mental illness; 2. Patients should actively engage in psychological counselling or listen to music or participate in sports activities while taking medication, and ensure sufficient sleep. 3, family care: family members should pay more attention to psychiatric patients, pay more attention to their usual behavior, and take them to the hospital for regular checkups; in serious cases, they should be sent to the hospital in time to receive systematic inpatient treatment to prevent loss of control and accidents.
