The choice of shoes has an important relationship with the health care of feet.

You can't wear tight shoes. If the shoes are small, the feet will be tightly wrapped, and the blood vessels in the feet will be bound, resulting in slower blood flow, reduced blood supply, blocked blood return, and the metabolic function of the whole body will also be affected. It is not uncommon for some people to wear tight shoes in modern times, and the smaller the size of shoes, the longer the size of shoes, the more the head of shoes passes through the tip, and the higher the heel of shoes. It is also considered as a fashion.

This kind of shoe shape limits the flexion and extension of toes, which not only makes the toes feel uncomfortable, but also easily leads to the valgus deformation of the first toe knuckle, and also leads to the change of the body's center of gravity, resulting in sprain, strain, back pain and so on. Many people have paid the price for this, chasing after unexpected diseases, and even need to undergo the pain of surgery to correct them. In the end, it is still unknown whether the deformed foot can be changed back to its original state.

The development of the foot should be natural, and we should not deliberately restrict it, put a spell on it at will, and we should not artificially change its shape and turn the originally good feet into deformed monsters.

Health needs to start from the feet.

Keeping feet warm is an important field of health care.

Because the foot is located at the end of the human body, far away from the heart, the blood supply is less, and the fat layer on the surface of the foot is thin, the heat preservation ability is poor, and the skin temperature of the foot is relatively low. People's normal body temperature is generally around 36.5℃, while the toe temperature is sometimes only 25℃.

There is a close nerve connection between the foot and the mucosa of the upper respiratory tract. The cold of the sole of the foot can reflexively cause the contraction of the capillaries in the mucosa of the upper respiratory tract, slow down the cilia swing and obviously weaken the resistance. As a result, all kinds of germs and viruses will take advantage of deficiency and multiply, causing diseases.

Some people have experimented that if you put your feet in cold water at 4℃, the temperature of the nasal mucosa will drop obviously. After a few minutes, there will be runny nose and sneezing, and colds will follow. After the cold pathogen invades the foot, it will also affect the heart, cause stomach pain, cause irregular menstruation, menstrual abdominal pain, low back pain, impotence and so on.

The foot is the "second heart" of people, and regular exercise of toes is helpful to the health of the brain.

Traditional Chinese medicine (TCM) has long had a scientific understanding of "cold starts from the foot", and put forward the scientific opinion of "keeping warm under the foot" in "Qianjin Yifang", which was written more than 1 thousand years ago, and it is still regarded as the experience of getting rid of diseases and prolonging life. The research on the relationship between feet and body health abroad is also very insightful. The Russian folk proverb says that "the head is not hot, the stomach is not full, and the feet are not cold", which reflects the Russian people's disease prevention measures.

Japanese scholars also summed up the method of peeping at human health from feet, pointing out that people should be able to stand upright with their feet neatly together between the ages of 6 and 30. If the feet can't be together at this age, it is the performance of premature aging; People who can stand for a long time are generally healthy; If it is difficult to stop for 15 minutes, there must be something wrong with the circulation system.

Insist on washing feet with hot water before going to bed, and soak feet with warm water15 ~ 20 minutes before going to bed, which can promote the vasodilation and blood flow of feet, and at the same time reduce the blood in the brain relatively, and promote people to fall asleep quickly. If possible, you can add some traditional Chinese medicines for promoting blood circulation to the hot water, such as safflower, Ligusticum chuanxiong, notoginseng, angelica, salvia miltiorrhiza, Spatholobus suberectus, etc., which will make you feel sleepy more comfortably and quickly.

In addition, you should pay attention to cover your feet when sleeping, which can not only plug the loopholes of cold pathogen invasion, prevent the occurrence of colds, but also improve the quality of sleep.
