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, they will wrap the feet tightly, which will bind the blood vessels of the feet, leading to slow 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 toe passes through the toe and the higher the heel. This is also considered a fashion.

This shoe type limits the flexion and extension of the toes, which not only makes the toes uncomfortable, but also easily leads to the valgus deformation of the first toe joint, and also leads to the change of the center of gravity of the body, resulting in sprain, strain, back pain and so on. Many people pay the price for this, chasing unexpected diseases, and even need to go through the pain of surgery to correct it. In the end, it is still unknown whether the deformed foot can return to its original state.

The development of the foot should be natural, and we should not deliberately restrict it and cast spells on it at will, let alone artificially change its shape and turn the original good foot into a deformed monster.

Health needs to start with 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 upper respiratory tract. Cold soles of the feet can reflexively cause the contraction of mucous capillaries in the upper respiratory tract, slow down the cilia swing and obviously weaken the resistance. In this way, all kinds of germs and viruses will take advantage of it and multiply in large numbers, causing diseases.

Some people have done experiments. If you put your feet in cold water at 4℃, the temperature of the nasal mucosa will drop significantly. After a few minutes, you will have a runny nose, sneeze and catch a cold. After the cold pathogen invades the foot, it will also affect the heart, cause stomach pain, 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 feet", and put forward the scientific view of "keeping warm under the feet" in "A Thousand Daughters of Fang Yi" written more than 1 thousand years ago, which is still regarded as the experience of getting rid of diseases and prolonging life. The research on the relationship between feet and physical health abroad is also very insightful. Russian folk proverb says that "the head is not hot, the stomach is not full, and the feet are not cold", which embodies the Russian people's disease prevention measures.

Japanese scholars also summed up the methods of peeping at human health from the 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 a sign of premature aging; People who can stand for a long time are generally healthy; If/kloc-can't stand for 0/5 minutes, there must be something wrong with the circulatory system.

Insist on washing feet with hot water before going to bed, and soak feet with warm water 15 ~ 20 minutes before going to bed, which can promote the vasodilation and blood flow of feet, reduce the blood in the brain and promote people to fall asleep quickly. If possible, some traditional Chinese medicines for promoting blood circulation, such as Carthamus tinctorius, Ligusticum Chuanxiong, Notoginseng Radix, Radix Angelicae Sinensis, Radix Salviae Miltiorrhizae, Caulis Spatholobi, etc., can be added to the hot water. It will make you feel more comfortable and sleepy faster.

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