Why is it that people in rainy days will be more depressed and seem to have no spirit?

Continuous rain and lack of light can easily lead to biological rhythm and endocrine disorder of human body, and then affect mood. Its main manifestations are inexplicable general fatigue, sudden feeling of sadness or irritability, and even severe depression-related symptoms. People's mood and emotions are related to the environment and climate. Long-term rainy weather is easy to make people's emotions "go downhill", especially for people with inner personalities who are not good at communicating with others.

Moreover, the lack of sunshine on rainy days leads to insufficient secretion of some hormones in the body, especially the decrease of dopamine secretion, which leads to insufficient excitement in the brain, which is manifested in low mood; If the air humidity is too high in rainy days, the pressure of the respiratory system will increase, which will easily cause psychological or physical discomfort.
