(2) Generally speaking, patients with anemia, gastrointestinal diseases, people with nutritional deficiency or hypothyroidism will cause systemic or local poor blood circulation, or peripheral blood circulation disorders of limbs will lead to cold hands and feet. Especially in the menstrual period of pregnancy and childbirth, women are more likely to cause cold hands and feet because of their weak constitution.
In medicine, frequent and long-term cold hands and feet can be called "chills".
It can be prevented and self-regulated if it is not very serious (generally not very serious, not unbearable biting cold).
First, strengthen physical exercise.
Especially those who sit for a long time or stand for a long time, we must pay attention to intermittent exercise, do more hands and feet and waist activities, and strengthen blood circulation.
Second, pay attention to diet.
Eat more warm food to improve the body's cold tolerance. Common warm foods are: cow, sheep, dog, chicken, garlic, pepper, ginger, onion, yam, longan and so on.
Third, three recipes
1. Fried mutton with shredded ginger
Slice the mutton. Shred ginger.
Add a little oil to the pot and bring it to a high fire. When the oil smokes, add pepper and star anise, stir-fry until fragrant, add shredded ginger, stir-fry, add mutton slices, add salt and monosodium glutamate, and pour sesame oil out of the pot.
2. Red dates and wolfberry mutton soup
Cut the mutton into eight pieces and soak the bleeding water in a boiling pot for later use. Wash jujube and wolfberry for later use.
Add water to the pot, add mutton, onion, ginger and aniseed and cook together. When it is half cooked, add jujube, medlar and salt, and then cook. If you don't like the taste of mutton, you can add one or two pieces of orange peel to increase dates to reduce the smell.
3. Three spice peppers
Red pepper (choose pepper varieties according to the spicy degree of food), put it on the fire and dry it until it is close to burnt; Peanuts, fried until crisp (sesame seeds are also acceptable); Bake the scallion on the fire until the outer layer is burnt, and peel off the outer layer.
Mash the above three raw materials in a mortar, then mix them together and add salt and monosodium glutamate.
For friends who like spicy and coarse grains, this dish is the most delicious-the participation of three spices in pancakes and stuttering is the most enjoyable. When eating "Golden Pagoda" (Wowotou), it is also a pleasure to put the three spices in the hole of Wowotou!
The above dishes must be useful for friends who are afraid of the cold. Just try it. People in this situation are prone to peripheral vasospasm. When they encounter cold air or cold water, the blood vessels in their hands and feet contract and the blood circulation is not smooth. Hands and feet are prone to cold and purple. In addition, it may also be because the sympathetic nerve function is not good, which leads to the inability to tighten muscles and produce heat and cold resistance when it is cold.
The human body temperature is kept between 36 and 37 degrees Celsius. When human skin comes into contact with external temperature, it will be directly transmitted to the life center of the brain, which controls breathing, heartbeat and body temperature. When the weather is hot, the body temperature control center will dominate the excitement of sympathetic nerves, making the skin capillaries and sweat pores open to dissipate heat and sweat; When you feel cold, sympathetic nerves will cause shivering in all parts of limbs, including muscles near the jaw, which will make muscles and fat cells generate heat energy due to contraction and resist the chill. This is why people will tremble when they feel cold.
People are warm-blooded animals, so basically there should be no question of "who is more afraid of cold". At the same temperature, some people may be particularly afraid of the cold because of their different subjective feelings. Of course, the fat layer can isolate the low temperature, but because the effect of fat cells on heat production is worse than that of muscles, people with thick fat may not be afraid of cold, but may be more afraid of cold!
Some diseases will affect the body's inadaptability to cold and heat. For example, patients with hyperthyroidism are quite heat-resistant because of excessive excitement and metabolism of sympathetic nerves; On the contrary, patients with hypothyroidism cannot generate enough heat energy to keep out the cold because of poor sympathetic nerve function.
There are also long-term smokers. Because of lack of oxygen in the body, the surrounding microvessels are prone to poor circulation. It is easy to feel cold when the arterioles are not smooth. However, if the venous microvessels are not unobstructed, although there is no feeling of being particularly afraid of cold, the blood vessels cannot expand and the blood cannot circulate, resulting in local hypoxia, and hands and feet are prone to chills.
Usually, urban "lazy people" who "can lie down and don't sit, but can sit and don't stand" will also have the problem of not being cold-tolerant because of the decrease of basal metabolic rate.
Women are afraid of cold, make up some iron.
Generally speaking, women are more afraid of the cold than men. Not long ago, two experts from an American institute of human health conducted a group experiment on female volunteers. The experimental report found that people with low cold tolerance have obviously insufficient iron content in their blood. The main cause of iron deficiency in women is menstruation, which leads to a large loss of iron.
As we all know, iron is an important raw material for producing hemoglobin, which is the main functional substance in red blood cells and is responsible for the transportation and metabolism of oxygen in the body. Iodine and tyrosine are the main raw materials for making thyroxine. Iodine needs to be continuously ingested from food, while tyrosine is generally synthesized by itself in the body. Long-term iodine deficiency will affect the synthesis of thyroxine and reduce the body's ability to keep out the cold.
How can I warm my hands and feet?
● Soaking hands and feet locally with hot water before going to bed can not only promote the circulation of vascular endings, but also help sleep.
● After bathing or soaking in hot water, put on socks to keep warm immediately after drying.
● If women are often afraid of cold feet in winter, they can put hot water, rice wine and ginger slices in a bucket (the ratio of hot water to rice wine is 1: 1). Watching TV or getting off work in winter helps to improve women's fear of cold.
Exercise is not afraid of the cold.
When the weather is cold, if you eat more and exercise less, it is easy to accumulate excess fat in your body. At this time, you can do more exercise, which can not only consume excess fat, but also strengthen blood circulation and warm your body.

For example, if you eat cold crabs, you can fry crabs with hot ginger to reduce the coldness of crabs. Common cold foods are loofah, wax gourd, celery, cucumber, kelp, frozen watercress, cabbage and so on. When cooking, you can use appropriate seasonings such as onion, ginger and garlic to achieve the effect of neutralizing the cold.
