The ancients advocated practicing at noon to achieve the intersection of heart and kidney. The so-called intersection of heart and kidney is to let heart fire intersect with kidney water and reconcile yin and yang. But the heart is above, because the fire, the kidney is below, because the water, it is easy to go down, so that the heart and kidney do not intersect, and the heart fire will make people in a state of excitement and can't sleep. This is insomnia. Modern people don't practice, and taking a nap is a way to make the heart and kidney intersect.
Besides taking a nap every day, it is also a good way to keep a good mood at all times. Because Chinese medicine believes that "the heart is happy with its wishes", it shows that the physiological function of the heart is closely related to the "happiness" in the seven emotions. Happiness is a pleasant mood, which is a good stimulus to the mental state of the body and is beneficial to the health of the heart and human body. Modern medical research has also proved that people who are cheerful and optimistic about life can live a long and healthy life, and the incidence of cardiovascular diseases is also significantly reduced; People who are impatient, depressed and full of pessimism about life are weak and sick, and the incidence of cardiovascular diseases (such as coronary heart disease and myocardial infarction) has also increased significantly. Being good at adjusting your emotions and keeping yourself optimistic and happy is the best way to keep your heart healthy.
