The premature senility of the old feet is a very scientific generalization and is the first embodiment of human body aging. The "premature senility of the old foot" is caused by internal and external factors.

The aging of the human body is complicated in reasons, and the reasons for this are determined by the processes of apoptosis, aging and death of cells. The apoptosis of the cell is the life cycle of the cell, the life cycle of the normal cell is about 40-60 days, and the life cycle of the erythrocyte is about 4-5 months, which is determined by the gene of the cell. The apoptosis of the cell is that the cell gene replicates a new cell membrane to replace an aged cell membrane to protect the cell and does not influence the life and the shape of the cell. The apoptosis of the body surface cells only forms 'dandruff', just like snake slough skin, and does not affect the change of the human appearance. And (3) each time the cell is subjected to apoptosis, the end mitochondria of the cell nucleus fall off by one section until the whole end mitochondria fall off, and the apoptosis of the cell is finished. Cell apoptosis is simply the onset of senescence and not the immediate death of the cell. The cells can not obtain nutrition and gradually age. The aging of cells in the body is the aging of organs, and the aging of the body surface is the accumulation of aging cells, which of course affects the appearance and shows that the human body begins to age. The latest medical clinical data statistics show that many diseases in the respiratory system, the digestive system, the cardiovascular system, the endocrine system, the immune system and the like of human beings are a manifestation caused by the fact that the system is aged and regenerated, and normal metabolism is difficult to maintain. The aging of cardiovascular diseases, diabetes, rheumatism and rheumatoid diseases is just the characteristic of the excessive aging of human beings.

The internal reason for the premature senility of the old foot is that the foot is farthest away from the heart of the human body, and the pressure for conveying blood is almost zero when the pressure generated by the contraction of the heart reaches the arteriole in front of the capillary vessel of the sole plate. The blood in the venules and veins behind the capillaries is returned to the heart by the suction force generated during diastole. Therefore, the local microcirculation of the sole plate is poor. Hands are far away from the heart, and some people can also feel cold in winter due to poor blood circulation.

The external factors of 'premature senility of the old foot' are that the foot plate is pressed for a long time, the arteriole, capillary vessel and venule of local microcirculation are pressed, and the cross section of the vessel becomes small and even is closed. The tissues of the foot are difficult to obtain enough nutrition and oxygen, the metabolism is deteriorated, and even the foot is cold, and the sleep is influenced. Although the hands are also far from the heart, both hands are responsible for all life activities, and the pressure generated when the hands exert force is only temporary. The old hand will not be senescent.

The above-mentioned internal and external causes cause poor blood circulation in both feet, and of course, aging gradually. Therefore, "the old feet are senescent" is the first manifestation of aging.

The sole plate is also called as the second heart of the human body, and the timely pressurization can also promote the local blood circulation, condition the endocrine system, enhance the organ functions of the human body and achieve the health-care effects of preventing and treating diseases.

The history of foot bath is thousands of years, the earliest literature record is 'elbow reserve acute prescription' of the jin generation, and the history has been for thousands of years. Modern foot bath apparatus includes foot bath basin, foot bath barrel, etc. and has certain curative effect. However, the water for foot bath contains the traditional Chinese medicine liquid for foot bath, when the initial temperature is proper, the feet can be quickly cooled when being immersed, and the muscle is a poor conductor of heat, so that the heat is difficult to be transmitted into the body from the outside, and if the temperature is too high, the feet are easy to be scalded, thereby the best curative effect is difficult to obtain. Refer to the Chinese journal of behavioral medicine 2001, the first year, the academic literature name "external causes of neck and shoulder pain and their prevention and treatment".

The foot health care instrument of the utility model does not rely on the water heat transfer of the traditional foot bath, but relies on the high-frequency current to accelerate the vibration of the water molecules of the lower limbs, and the water molecules rub each other to generate heat, so that the temperature of the two lower limbs is raised simultaneously, the blood circulation of the foot is promoted, and the lower limbs obtain enough nutrition and oxygen; through the regulation of the human body temperature regulation center, sweat glands of the whole body are opened to perspire, the excretion of wastes in the body is accelerated, and the feet and the body temperature are ensured not to exceed 42 ℃.

Therefore, the foot health care instrument of the utility model can gradually accelerate the blood circulation in the body and make the whole body feel warm; maintain normal metabolism, relax muscles and tendons, promote blood circulation, relieve pressure, and achieve the effects of tranquilizing.

Alternating current with a frequency greater than 100 kilohertz (100,000 hertz) is referred to as high frequency current. It propagates all around in the form of electromagnetic waves. The speed of electromagnetic wave propagation in space is equal to the speed of light, and is 3X 108 m/s. The frequency of the high frequency current is inversely related to the wavelength and can be expressed by the following formula: and f is V/lambda. Where f is the frequency in Hz, λ is the wavelength in m, and V is the speed of light in m/s. Therefore, knowing the frequency of the high frequency electric wave, the wavelength can be calculated, and knowing the wavelength, the frequency can also be calculated. The method of applying high-frequency electricity to human body to prevent and cure diseases is called high-frequency electrotherapy.

The high-frequency electricity has the following characteristics when acting on a human body:

the electrolysis is not generated, the current is alternating current with positive and negative, and the ions move to one direction in the positive half cycle; in the negative half cycle, the ions move in the opposite direction, so that no electrolysis is generated.

(II) No stimulation of the neuromuscular action according to electrophysiological measurements, the duration of stimulation should be 0.3 and 1ms, respectively, if it is desired to cause stimulation of the nerve or muscle. However, when the frequency is greater than 100,000 Hz, the time of each period is less than 0.01ms, and the cathodic stimulation only occupies 1/4 (0.0025 ms), both values do not reach the excitation requirement, so that the high frequency electrical frequency is very high, and no matter how many periods are passed, the neuromuscular excitation is generally not caused to generate the contraction response under the normal condition.

When the high-frequency electricity passes through the human body, the heat effect and the non-heat effect can be generated in the tissues, and in the low-medium-frequency current, the current passing through the tissues is small, so that enough heat cannot be generated. However, at high frequencies, the capacitive reactance XC drops sharply due to the frequency increase, and the tissue resistance drops significantly to hundreds, tens, or even several ohms, so that the current passing through the human body increases sharply. According to Joule-Lenz's law, Q is 0.24I2Rt, wherein Q-generates heat, I-current intensity, R-resistance and t-electrifying time, so that thermal effect can be generated in high-frequency electric tissues. In addition, when the high frequency electric wave is applied to the human body at an electric field intensity that does not cause an increase in body temperature, the physicochemical properties and physiological reactions of tissues can be changed, which is called non-thermal effect.

And (IV) during high-frequency electric treatment, the electrode can be separated from the skin, and when low-frequency and medium-frequency electric treatment is carried out, the electrode needs to be in close contact with the skin, otherwise, current cannot be introduced into a human body, the reason is that when the electrode is separated from the skin, the electrode and an air gap between the skin and the electrode form a capacitor, the skin and the electrode are equivalent to two conductors of the capacitor, and air is equivalent to a medium.
