Autumn and winter "hurt spring and grieve for autumn" is caused by disease and insufficient sunshine.

In China's ancient poems, it is not completely unscientific to "grieve for spring and grieve for autumn". It is possible that the patient suffers from seasonal emotional diseases belonging to emotional disorders. The patient began to be depressed in autumn and winter, and gradually recovered in spring and summer. The main reasons for this situation are the shortening of light and the imbalance of day and night cycle, which have affected the neuroendocrine and the brain's function of regulating emotions, making the melancholy mood accompany the sprinkling season, and the psychology is also affected by the cold current. Seasonal affective disorder (SAD) is not only a typical symptom of depression, such as depression, loss of vitality and fatigue, but also often accompanied by drowsiness, increased food intake and weight gain, some of which will greatly increase the demand for carbohydrates. Dr. Xu Haochong, director of the Psychiatry Department of Renai Hospital of Taipei United Hospital, said that seasonal emotional disorder is more likely to occur in high-latitude countries, mainly because of the shortened light, the imbalance of day and night cycle, and the impact on physical and mental health. Because the sunshine time is shortened after autumn, the neuroendocrine and the brain's function of regulating emotions are affected, and the functions of serum hormones and melatonin, which are closely related to depression, will also increase or decrease with the change of seasons and the length of sunshine time. In addition, Dr. Xu pointed out that the weather in autumn and winter is often bad, so the original itinerary is destroyed or changed, and people are less inclined to walk outdoors, which is also the original reason for psychological depression. According to foreign statistics, women of childbearing age are four times more likely to suffer from depression than men, and about 60% patients suffer from this disease for a long time. Dr. Xu Haochong pointed out that in addition to antidepressants, phototherapy is a common treatment method in high-latitude countries, including light boxes and dawn simulators. The light box allows patients to receive a certain time and intensity of light every day, while a dawn simulator is placed in the room, and the brightness is gradually increased by 1-2 hours to simulate the sunrise process. Dr. Xu Haochong said that Taiwan Province Province belongs to a low-latitude country, and typical symptoms of seasonal depression are relatively rare. Although a few hospitals in Taiwan Province Province have introduced phototherapy, it is still not common in Taiwan Province Province. It is suggested that patients with depression can go outdoors more and adjust their regular schedule. Exercise can not only increase blood circulation, relieve physical pain and other discomfort, but also promote the increase of serotonin, hormones and dopamine in the brain, which can alleviate the negative emotions caused by seasonal depression.
