Is there any scientific basis for the saying "a calm heart is naturally cool"?

The phrase "a calm mind is naturally cooler" originates from ancient Chinese Taoist and Buddhist culture, emphasizing the importance of inner peace and tranquility for physical and mental health. Although this saying is widely used in traditional culture, it does have some basis from a scientific point of view.

Studies have shown that emotions and stress have a great impact on physical health. Prolonged exposure to tension and anxiety can cause the body to secrete health-harming hormones such as adrenaline and glucocorticoids, which can negatively affect the cardiovascular, immune and nervous systems. Relaxation techniques such as walking and meditation, on the other hand, can reduce psychological stress, which in turn reduces the likelihood of producing these hormones and makes one feel more comfortable and relaxed.

In addition, some studies have shown that through psychotherapy, meditation, and other techniques, a person's emotional experience, sense of well-being, and harmonious relationships can be improved, leading to better control and prevention of a number of related diseases.

To summarize, although the saying "a quiet mind is a cool mind" is not entirely scientific, it is good for health to appropriately relax and maintain mental peace. When we are able to maintain a calm mind, we are better able to cope with challenges and stresses, and at the same time better able to enjoy the joys of life.
