My son is only 8 years old. Why is he so afraid of the cold? What should he eat to avoid being so afraid of the cold?

Eat more mutton, dog meat and other foods that have the function of warming kidney and strengthening yang, as well as peppers, shrimps and walnuts. It is very helpful to improve the ability to keep out the cold. Mutton is sweet and warm, rich in fat, protein, carbohydrates and minerals such as calcium, phosphorus and iron. It can warm the middle warmer, tonify deficiency, nourish the kidney and liver, stimulate appetite and strengthen the spleen, and is a good product with rich nutrition in winter. Dog meat is sweet in taste and warm in nature, which can tonify the middle warmer, replenish qi, warm the kidney, strengthen yang, soothe the five internal organs, strengthen the waist and knees, and warm the lower energizer. It is rich in protein, carbohydrates, calcium, iron and phosphorus, and has the function of warming the body against the cold for patients with cold limbs, backache and weak constitution. As the saying goes, "Eat dog meat to warm up, and you can spend the winter without a quilt." Pepper contains capsaicin, which can stimulate appetite, promote digestion, make people's heart beat faster, dilate peripheral capillaries and increase body surface blood flow. Eating some peppers properly in winter can make people feel warm and comfortable, and can prevent cold and humidity from damaging joint muscles. The contents of protein, calcium, phosphorus and iron in shrimp skin are higher than those in meat, eggs and milk. Has effects in warming kidney, strengthening yang, invigorating spleen, regulating stomach, and dredging blood vessels. It is most suitable for patients with spleen and kidney yang deficiency, impotence and low back pain to eat in winter. Walnut kernel contains more than 40% fat, mainly unsaturated fatty acids, which can lower cholesterol and prevent arteriosclerosis and hypertension. Its rich phospholipids are important raw materials for human cells, which can enhance cell activity, promote hematopoietic function and stimulate appetite. In addition, it is also rich in carbohydrates, with high heat production, which can increase the human body's heat and keep warm from the cold. It is worth mentioning that it is a common misunderstanding to keep out the cold by drinking. Because the wine itself produces little heat energy, the whole body feels hot after drinking, which is the result of alcohol dilating blood vessels and emitting the original heat energy of the human body. A large amount of heat energy previously stored in the body radiates to the outside, but the ability to keep out the cold drops, which often makes people get goose bumps all over the body. This is what people often call "cold after drinking". Experts suggest that women who are afraid of cold can consciously increase foods with high iron content, such as animal liver (such as pig liver) and other internal organs, horse meat, egg yolk, beans, painful meat, fish, spinach and so on. And some foods with high calories, such as mutton, dog meat, beef, rabbit meat, goat's milk, shrimp skin, shrimp skin, leek and so on.
