There are several reasons for being emotional at night, it can be the influence of the biological clock and endocrine, or it can be psychological.
The main reason for being emotional at night is the influence of the biological clock and endocrine. At night, the body's biological clock and endocrine system adjust to rest and recovery mode, which can cause emotions to become more sensitive and irritable. In addition, psychological factors can also affect the mood at night. People are more likely to recall past experiences and emotions at night, which can lead to mood swings and sadness. There are also studies that suggest that poor light at night may affect mood. Light exposure can affect the biological clock and endocrine system, and if there is not enough light at night, it can lead to mood problems. In addition to the influence of the biological clock and endocrine, psychological factors are also one of the important reasons for being emotional at night. At night, people are more likely to feel lonely, anxious, and depressed, probably because the evening is the time when people are most likely to think about their hearts. Some people may feel stressed and exhausted at night, which can lead to emotional instability.
Understanding mood changes at night and taking steps to regulate our emotions can help us better cope with mood swings at night.
