With the development of today's society, people's requirements for the quality of life are getting higher and higher, and various ways and means of health preservation are also increasing, such as diet therapy, medicine therapy, qigong, meditation, fitness exercise and so on. This makes life very colorful and really plays a good role in preventing diseases and strengthening the body. However, whether it is fitness exercise, diet therapy or drug therapy, mental health and mental pleasure must be the premise in order to expect them to achieve good results. A person who is fidgety, anxious and sad all day, no matter what "panacea" he takes or how he nourishes, can't be refreshed and healthy.

Health care must first nourish the heart, and the combination of health care and heart care can achieve the satisfaction of health care. What is nourishing the heart? The heart is the state of mind! Nourishing the heart means trying to keep yourself mentally healthy, cheerful and high-spirited through various means. As psychosomatic medicine points out, true health must be the perfect combination of mental health and physical health, and must have good social adaptability. In fact, the heart is closely related to the body, and a person's mental state can greatly affect the neurohumoral-endocrine and immune regulation system inside his body. This system determines whether it can maintain the harmonious relationship between various organs of the body, maintain the dynamic balance of the internal environment, and determine whether it can adapt to the constant changes of the external environment and effectively deal with various external stimuli and pathogenic factors.
