What is the relationship between emotion and disease?

Emotion is closely related to people's health and longevity. Pavlov believes that emotion is similar to instinct and related to subcortical tissue. Being in a bad mood has a bad influence on the human body. Medical experiments show that when people are in pain and anger, diastolic blood pressure increases obviously due to the strengthening of external arterial resistance, while when they are in fear, cardiac output increases and systolic blood pressure increases, which will lead to a heart attack.

If a person is depressed all day, it will cause epigastric discomfort, pantothenic acid, loss of appetite and weight loss. Nervous emotions will affect the body's resistance and make people easy to get sick. Long-term emotional depression, excessive sadness and fear may also lead to mental illness.

The influence of meteorological conditions on mental health has attracted great attention from psychologists, behaviorists and management scientists. Some countries publish weather forecasts, as well as physical and psychological diseases that may be caused by the weather in the future, and suggestions on disease prevention measures tailored to nature.
