The autumn breeze is chilly, and as the weather turns cooler, the problem of dry, itchy skin plagues many people. How to deal with it? First of all, you need to exclude some pathological conditions, when some middle-aged and elderly people if there is a persistent itchy skin, then we should be alert to whether it is caused by diabetes or bile duct obstruction, etc.. The itchy skin caused by the change of seasons is mainly due to the lowering of temperature, the body instinctively to reduce heat dissipation off the skin part of the capillaries, reduce blood flow at the same time sweat, sebum secretion is also reduced, so that the skin humidity decreased to dry skin eventually lead to itchy skin. I believe that the term “water-oil balance” is not unfamiliar to everyone, and this is the standard for measuring the health of the skin. From the perspective of water-oil balance, skin types can be divided into four categories: dry, normal, oily and combination. Undoubtedly dry skin is the most prone to itchiness. So what is the connection between nutrition and moisturizing to stop itching? 1, by drinking water to replenish skin moisture? Did you know that 500ml of water is not discharged from our skin daily, which is equivalent to a bottle of mineral water! If sports sweating, fever from the skin to lose more water, skin loss of water is not timely replenishment will accelerate skin aging, dryness and even itching. “Water is the source of life”. In addition to the three meals we drink at least 1200ml of water, drinking water should be a small number of times appropriate, preferably in the morning, 10:00 am, 2:00 pm, 5:00 pm, 8:00 pm, before going to bed each drink a glass of water. In dry autumn and winter, it is advisable to use warm water, honey water or wolfberry water with moistening effect; some studies have found that manganese has the function of maintaining normal peripheral nerve conduction, which can reduce the occurrence of skin itching, tea is rich in manganese, so it is also a good choice to make some tea to drink. 2, collagen is important for skin moisturizing? Is it effective to eat directly? Collagen is the main component of the human skin dermis, which together with a small amount of elastin constitute a regular collagen fiber mesh structure and transport water for the epidermis. Moisture accounts for 40-60% of the body weight, as protein is hydrophilic, if the body lacks protein means a decrease in water, easy to cause skin aging and loss of elasticity. It is said that protein is an important substance indispensable for skin brightness, then the public think that “pig skin”, “chicken claw” and other collagen-rich food is useful for the skin? The protein is like a house, and the amino acids are like the bricks that make the house. Collagen is not directly absorbed by our body, but must first be turned into the materials for building a house: amino acids and short peptides. If you take it as a supplement to amino acids, it is not as good as the high quality proteins we often talk about in eggs and milk, because collagen is an incomplete protein. If we take it as a supplement of short peptides, can it be an “ideal brick”? It doesn’t seem to be suitable, the body’s protein has to be synthesized in the cells, and these short peptides can’t enter the cells as the raw material for protein synthesis. Then is it a “qualified construction worker”? Can it help the skin to synthesize collagen? Unfortunately, there is not enough scientific evidence to support this. What is generally accepted by the scientific community is that vitamin C has a role in promoting collagen synthesis. Many skin care products have added collagen, some claiming to be “small molecules and active substances,” but it is basically impossible for the applied collagen to be absorbed into the skin, and it will not become collagen in the skin. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. 3, why weight loss may also induce itchy skin? It can be said that weight loss is a year-round “must” for many women, and when it comes to weight loss we must first make it clear that it is not meat and vegetables that make us fat, nor is it staple food, but too much energy. The word “balanced” is the essence of the “world of nutrition”. Many nutrients are closely related to the health of the skin, one cannot be missing. In order to lose weight, many girls do not eat meat and vegetables, which will cause insufficient intake of high-quality protein, resulting in a reduction in the body’s water content, prone to dry, itchy skin. Some people basically do not eat staple foods, not to mention the intake of coarse grains, which is an important source of B vitamins, B vitamin deficiency and itchy skin related. For women who have lost weight, it can be said that the talk of “oil”, but grease is really so useless? In fact, “oil” is as indispensable as water, it is a necessary nutrient for the skin to carry out metabolism, without it, our skin will lose its luster. Vitamin A is the most relevant nutrient to epithelial health, which mainly exists in animal liver, whole milk, poultry eggs; its precursor substance – beta carotene can be converted into vitamin A in the body, rich in dark green or red-yellow vegetables and fruits. 4.How to eat a hydrated and beautiful skin in autumn and winter? In order to ensure a balanced diet, an adequate amount of water on the basis of we can not forget the contribution of fat, now we all know the benefits of polyunsaturated fatty acids such as w-3 fatty acids, but in fact, saturated fatty acids are also necessary for our body every day, the latest research shows that saturated fatty acid intake below 10g / d, total mortality, cancer mortality, coronary heart disease mortality, stroke mortality can increase by 2 times. So moderate amount of eating some pork rinds, chicken feet and other fat relative to fatty tissue less, but there is a moderate amount of fat food or some benefits, from the perspective of traditional Chinese medicine may also have a “shape to complement the shape” role. In addition, autumn and winter we can eat some nuts, such as almonds, hazelnuts, walnuts, pine nuts, etc., because they contain polyunsaturated fatty acids, B vitamins, vitamin E and manganese, they play an important role in maintaining skin health, preventing itching. From the point of view of Chinese medicine food therapy, “the lung is the main skin, white food into the lung meridian”, commonly said that the white food has a nourishing role in moistening the lung, and benefit the lung is conducive to the health of the hair and skin. Therefore, you can appropriately use silver fungus, snow pear, lily and other foods. Here we recommend a recipe to everyone: white jade red dates coix seed porridge [ingredients] silver fungus, snow pear, lily, coix seed, red dates [efficacy] nourish yin and moisten the lungs, blood and skin, improve the rough and dry skin 5, prevent dry skin, itching tips dietary should pay attention to: reduce the itchy skin triggers: eat less spicy stimulating food, such as chili, pepper, mustard, strong tea, strong coffee, etc.; less alcohol and less smoking. Life should pay attention to: dry season use humidifier to adjust indoor humidity; do not use too hot water bath, can use body wash every other day, do not forget to use moisturizer after bathing; avoid excessive scratching skin.
