Generally speaking, anemia and gastrointestinal diseases, malnutrition or hypothyroidism cause systemic or local poor blood circulation, or limb peripheral blood circulation disorder 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" (Wotou), it is also a pleasure to put three spices in the hole of Wotou!

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.
