When Zhang Weiting came to the wet and cold autumn and winter, even though he was wrapped like a zongzi, he tried not to go out indoors and covered with a thick quilt at night, he still felt extremely cold. His fingertips and toes are always cold, and even his fingertips feel a little dull. Winter is a season when the problem of deficiency and cold is particularly serious. Coupled with the reduction of exercise, it is easy to cause poor blood circulation and low metabolism, which will not only make you fat, but also reduce your immunity. Although everyone knows that ginger is a good warming food, in fact, ginger has two different functions. By taking different ginger in the morning and evening, you can adapt to the periodic rhythm of the body and improve your cold constitution! Morning: Ginger powder is made by heating and drying ginger, which is called "dried ginger" and has the effect of warming and nourishing the body from the five internal organs. Although it is generally believed that eating raw and complete ingredients will be healthier, after heating, the nutritional component of ginger, gingerol, is 2-3 times higher than that of raw materials, and it can be increased to about 30 times if it is steamed. Gingerol can directly increase the blood flow to the stomach, improve the deep heat energy of the body, promote blood circulation, improve deficiency cold and sympathetic nerve, and burn fat to generate heat energy. Manet Iwata, a Japanese traditional Chinese medicine dietotherapy teacher, did not point out that the morning is the time to switch from sleep mode to metabolic mode and from parasympathetic nerve to sympathetic nerve, so taking ginger powder in the morning can warm the sympathetic nerve from the body. A few years ago, there was a rumor on the Internet that "eating ginger at night is like eating arsenic", claiming that ingredients originally thought to be beneficial to health were toxic at night, which made people panic. But this rumor is too exaggerated and there is no evidence. Although ginger can warm the body and promote blood circulation, it is only the role of spices and seasonings. The amount of each meal will not be much, nor will it be overly excited and hot. Of course, it is nonsense to become toxic. On the contrary, ginger can dilate the peripheral nerves of hands and feet and promote smooth blood circulation. Because our body has to switch from active sympathetic nerve to rest parasympathetic nerve at night, it will dilate blood vessels, cool down deep body temperature through hands and feet, and prepare for sleep. People who have cold hands and feet and can't sleep well easily can't dissipate heat smoothly because of poor peripheral blood circulation. Therefore, ginger can dilate the blood vessels of hands and feet, and its action principle is the same as that of parasympathetic nerve, which can help the deep body temperature drop. Therefore, for people who can't sleep well due to deficiency and cold, eating ginger at night is helpful to improve the quality of sleep.
