Herman Joerhaff, a famous Dutch physicist and chemist, left a sealed book when he died in 1723. The cover says, "The only profound secret lies in medical skill." The book was bought and sold intact at the price of 20 thousand gold coins. The buyer opened the book with great interest and couldn't wait to turn it over. The result was disappointing. It turns out that this * * * book has 100 pages, but 99 pages are all blank pages, leaving only the scientist's handwriting on the title page of the book: "Keep your head cold and your feet warm, so that the most famous doctor will become poor."

This scientist, after a lifetime of experience, hit the nail on the head, wrote sharp comments on "head" and "feet", pointing out that the secret of a long and healthy life is that "the head is not cold, and the feet are not warm". The so-called "cool-headed" means to make psychological adjustment and calm down when things happen; The so-called "foot warmth" refers to foot health care that eliminates illness and prolongs life. There is also a proverb in our country: "If you want to be safe, your feet should be warm", which coincides with the view of this Dutch scientist. In addition, there are many "decisive" folk proverbs, such as: "When a tree dies, its roots are exhausted first, and people get old first"; "Raising trees needs to protect roots, and raising people needs to protect feet"; "The disease starts from the foot and the foot is like a root. Treat the feet and treat the whole body "and so on. Foreign medical scientists have also paid enough attention to the foot, calling it "the second heart of the human body" and "the pump of the heart". .

Doing foot health care well can be roughly summarized into five aspects: moving feet, soaking feet, warming feet, protecting feet and pressing feet.

Moving your feet means that your feet should keep moving. Don't travel by car, walk slowly. Walking is the simplest exercise. Because moderate exercise and activities in a fresh environment are beneficial to muscles, joints, heart, breathing and nervous system. When walking, people will drive half the bones of the whole body to relax and contract rhythmically, so that the function of peripheral arterioles will also relax and contract, thus promoting the blood of lower limbs to return to the heart, which is beneficial to the blood circulation of the whole body.

There are also some sports methods abroad-abnormal sports, such as walking backwards, barefoot, walking in the rain and so on. Among them, walking backwards is more acceptable. The principle of fitness is backward. Walking forward at ordinary times can make some inactive muscles and joints move. Moreover, exercise the function of balance and orientation backwards. Walking backwards can also avoid the occurrence of chest hunchback.

Soak your feet with hot water at about 40℃ for about 20 minutes before going to bed every night. This will allow all acupoints on the feet to receive heat and promote the operation of meridians. The amount of water used to soak your feet in hot water is as deep as your ankles. When washing feet, gently rub your hands on the foot surface and foot center in turn. This method of washing feet is suitable for all seasons. Its main function is to dilate capillaries, promote peripheral circulation of feet, reduce muscle tension and help relieve foot fatigue. There is a folk saying that "cold face warms teeth and hot feet" and a proverb that "washing feet with hot water is like taking tonic", which shows the benefits of washing feet with hot water.

Sun Simiao, an ancient physician in China, clearly pointed out that cold feet would affect the function of viscera and cause a series of diseases, such as stomach pain, lumbago and leg pain, irregular menstruation in women and impotence in men. From the point of view of modern medicine, it is considered that the foot is farthest from the heart, the blood circulation route is long, the blood supply is less, and the warm-keeping function is poor. Therefore, old people, young people and pregnant women should wear warm shoes and socks in winter. Sweaty feet should also be padded with sweat-proof insoles to ensure moisture absorption and warmth, so that the microcirculation of the feet can operate normally.

Foot protection is mainly to wear suitable shoes. Modern people often pursue beautiful and fashionable shoes, but put "comfort" in the second place. Some people even "cut their feet to fit their shoes", preferring their feet to be squeezed to adapt to fashionable shoes. Therefore, leg, foot and waist diseases caused by improper shoes often occur. High-heeled shoes, platform shoes, and pointed leather shoes can all cause diseases in the feet and toes, and sometimes the joints of lower limbs and lumbar vertebrae will also be affected. Therefore, the shoe type and heel should be moderate. Due to tissue degradation, the elderly are prone to fat feet, so they should wear cloth shoes or sports shoes with loose and elastic soles.

Massage the soles of your feet often. You can massage your feet while watching TV at night. Massage the soles of the feet can make the nervous and endocrine systems more coordinated, and has the functions of relieving fatigue, resisting aging and improving liver and kidney functions. Methods: First bend one foot, hold the instep with the same hand, and rub the instep repeatedly with the thumb or middle finger of the other hand for up to 1000 times, and exchange left and right. If you hit Yongquan point and Ganjing point in the foot heart with a health hammer, the effect will be better.
