The benefits of washing feet promote blood circulation.
Generally speaking, body temperature is closely related to blood circulation. When the body temperature is low, the blood circulation is low, and when the body temperature is high, the blood circulation is also vigorous. Washing feet with hot water can improve the blood circulation of feet. The warming effect of water can dilate the blood vessels in the foot and raise the skin temperature, thus promoting the blood circulation in the foot and the whole body. At the same time, washing feet with hot water also increases the blood flow rate and flow of feet, thus improving heart function and reducing heart load. After testing, healthy people soak their feet with water at 40-50℃ for 30-40 minutes, the whole body blood flow will increase by 10- 13 times for women and 18 times for men. It can be seen that washing feet with hot water can make blood circulation smooth and improve.
The benefits of washing feet 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.
The benefits of washing feet 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.
The benefits of washing feet 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.
The benefits of washing feet are health and beauty, nourishing and protecting the brain.
Washing feet with hot water can regulate meridians and qi and blood. At the same time, the blood vessels in the foot dilate and the blood volume increases, thus accelerating the blood flow in the head and supplementing the oxygen and nutrition needed by the brain in time. Especially in winter, daily foot washing can not only keep feet clean, enhance metabolism, and improve resistance to foreign pathogenic microorganisms.
