It rains every day, so I am very upset. How to comment

In fact, the relationship between weather and mood is not that simple. From a physiological point of view, the pineal gland in human body secretes less pineal hormone under strong sunlight, while the concentrations of thyroxine and adrenaline are higher. Rainy days are not good and vice versa. Thyroxine and epinephrine can promote nerve excitation and cell metabolism, and stimulate tissue growth, maturation and differentiation. Therefore, sunny days often make people feel refreshed, while rainy days make people listless and unhappy.

But this is not absolute, because our conscious activities and emotional mentality are not only limited by physiological conditions, but also influenced by culture. Just like when we were young, when we wrote a composition about Tomb-Sweeping Day's sacrifice to the martyrs, we would write "It's raining, just like God is crying". Our culture associates rainy days with sadness and sadness. When almost everyone sees the words "rainy weather", they will think of some sentimental poems, such as "rainy in Qingming Festival", "lilacs are empty, and sorrow in the rain". Of course, not everyone will always have similar associations. Where petals flow like tears, when we are in a low mood, it is natural that all kinds of sentimental emotions will be triggered by lingering rain.
