Busy day, foot soak before bed can not only promote blood circulation, and can eliminate the fatigue of the whole day; human physiological activities are cyclical, the ancients said: sunrise and do, sunset and rest, the morning gas to rise and develop, the opposite at night, the need to converge, so our daily routine must also comply with this law to get rid of sub-health. The golden time period of foot soak is: 9:00 pm to 11:00 pm. Soaking feet from 9pm to 11pm is the most suitable, so we must let our qi and blood and spirit return fully before 11pm. For some brain workers, thinking about the day’s problems, plus the brain is more excited, the overall are Yang is not into the Yin phenomenon, sleep at night is more difficult. After the warm water soak feet spirit and blood will be easier to return, return is also to return to their home base, the kidney is the main collection of essence, so the collection after the kidneys. The human body’s kidney meridian is from the foot, warm water soaking feet on the kidney meridian to play a warming effect, the kidney meridian will naturally also form a good effect on the kidneys. Therefore, although there is no measure for the kidneys, through the meridians can also play the effect of kidney. It should be noted that the water temperature of the foot soak must be moderate, if the water temperature is too hot, the hot nature of the publicity, not only can not help the kidney collection, but make people more excited, which increases the consumption of kidney essence; if the water temperature is too cold, cold condensation, will lead to the meridian occlusion, and cold will follow the meridian into the abdomen, and its harm is self-evident.
