1, improve sleep
The foot is rich in nerve endings and capillaries. Soaking feet with hot water has a mild and good stimulating effect on nerves and capillaries. This kind of warm stimulation is reflected in the cerebral cortex, which has an inhibitory effect on the cerebral cortex and is the smooth transformation from excited sympathetic nerve to parasympathetic nerve. After the parasympathetic nerve is excited, people are in a state of quiet rest, thus improving sleep and eliminating insomnia.
2. Promote metabolism
Washing feet with hot water can promote blood circulation of feet and whole body. Due to the increase of blood circulation, it regulates the secretion of various hormones through endocrine glands, such as thyroid hormone secreted by the thyroid gland and adrenal hormone secreted by the adrenal gland. These hormones can promote metabolism.
3, prolong life
Chinese medicine believes that the five internal organs of the human body have corresponding projections on the feet. There are 12 meridians connecting human organs, six of which start from the foot, so the foot is the beginning of three yin and the end of three yang, and there are more than 60 acupoints on the foot to communicate with the internal and external environment. If you can insist on washing your feet with hot water before going to bed, you can stimulate these acupoints, promote the circulation of qi and blood, regulate the functions of the five zang-organs and six fu-organs, and dredge the meridians of the whole body, so as to get rid of diseases and exorcise evil spirits, replenish qi and remove blood stasis, and nourish vitality.
Modern medicine also believes that the foot is the "second heart" of the human body, and there are countless nerve endings in the foot closely connected with the brain, which is closely related to human health. Therefore, washing feet with hot water can enhance the body's immunity and resistance, and has the effects of strengthening the body and prolonging life.
4, eliminate fatigue
When the human body is tired, the blood circulation of the foot is poor, and substances such as metabolic end products, calcium salts and lactic acid microcrystals are deposited first. When an organ of the human body is abnormal or sick, due to the influence of pathological reflection, the blood circulation of the foot is worse and deposits are more likely to be produced. After a day of strenuous exercise, athletes have an average of 30 mg of lactic acid per kilogram of blood. After soaking feet in water at 43℃ for 30 minutes, blood samples will be taken for examination, which will drop by about 5 mg. After a period of foot washing, the lactic acid in the blood will drop by about 20 mg, and it will return to the level of lactic acid in the blood when it is almost tired. It can be seen that washing feet with hot water is the simplest and most effective way to eliminate physical fatigue.
Seeing so many benefits above, I believe you want to wash your feet every day, so take action. Insisting on washing feet is the best health care method, especially suitable for white-collar workers and heavy manual workers, which can reduce the fatigue of one day's work and help you to work with full spirit the next day.
