In the same way, why are some people particularly afraid of cold? 10

Staying in the same icy and snowy environment, some people shivered from the cold, while others broke the ice and played in the water. Afraid of the cold, not afraid of the cold, not in age, not fat and thin, not in gender. The winter swimming teams, old and young, fat and thin, men and women, are proof of this.

Why are some people afraid of the cold, while others are not afraid of the cold? The latest explanation: It is related to the secretion of thyroid hormone in each person's body.

American nutritionist Verde and University of Pennsylvania professor Rukasky did an experiment: let 120 middle-aged women wear swimsuits and swim in cold water, and then the 30 women who first felt cold and stopped swimming and dressed, and the 30 women who did not feel cold and finally went ashore for blood analysis and control, the results found that the average blood thyroxine content of women in the group without cold was more than 1 times higher than that of women in the cold group, thus revealing the mystery of why some people are particularly afraid of cold.

It is now known that thyroid hormones have a thermogenic effect, which can accelerate the oxidation process of tissue cells in the human body and increase the body's heat production. According to experts, 1 milligram of thyroid hormone can produce about 1 kilocalorie, which is equivalent to the heat produced by 250 grams of glucose or 110 grams of fat. Thyroid hormones can also increase the body's basal metabolic rate, speed up the blood, thereby increasing body temperature and enhancing cold resistance.

People with insufficient thyroxine secretion have less heat production, so they cannot adapt well to the cold environment, and often need to use heat-producing diet and clothing to keep out the cold. Scientific research has learned that iodine and tyrosine are essential raw materials for the thyroid gland to produce thyroid hormones, and if the food eaten in daily life is deficient in iodine and tyrosine for a long time, it will affect the synthesis of thyroid hormones, and the body's cold tolerance will be greatly reduced.

In order to improve people's cold tolerance, experts suggest that in winter, eat more iodine-rich foods such as kelp, seaweed, and marine fish, and eat more tyrosine-rich foods such as frozen tofu, tofu skin, soybeans, and caviar, so as to provide sufficient raw materials for the thyroid gland to make thyroid hormones. In addition, dog meat, lamb, beef, lobster, mussels, etc., which are rich in fat and protein, can promote metabolism, increase heat energy, and also help keep out the cold.

Because some people belong to the constitution of being afraid of cold.

If you want to improve, you need to do the following.

First, more outdoor sports.

Second, if you are not fat, eat more fatty meat, beef, mutton, and dog meat.

Thirdly, if you are anemic, you can eat red dates, longan, wolfberry, ferrous gluconate and vitamin C, and fourthly, if you are afraid of cold caused by iodine deficiency, you can eat seaweed and kelp.

Constitution is formed by innate inheritance and acquired acquisition.

Fear of cold in winter and heat in summer This is the combination of yin deficiency and yang deficiency, both yin deficiency and yang deficiency, called yin and yang deficiency, its main manifestations are both fear of cold and heat, especially afraid of cold in winter, and particularly afraid of heat in summer, which is the imbalance of yin and yang or the constitution of yin and yang deficiency.

In case of cold food and stomach discomfort, dry ginger can be decocted in water, and the juice can be used instead of tea to relieve symptoms.

It is considered that this condition may be caused by kidney yang deficiency, which is related to insufficient body temperature and waist malnutrition.

It is recommended not to eat raw and cold food, pay attention to keeping warm, you can massage the Ba Ji acupoint, and first take Guifu Dihuang pills orally**.

Human beings are homeothermic animals, basically there should be no so-called "who is more afraid of cold" problem, at the same temperature, due to the individual's subjective feelings are different, it may indeed appear that some people are particularly afraid of cold. Although the fat layer can insulate from low temperatures, because the thermogenesis of fat cells is worse than that of muscles, people with thick fat are not necessarily less afraid of cold, but may be more afraid of cold! Some diseases can affect the body's discomfort to heat and cold, such as patients with hyperthyroidism, who are quite intolerant to heat due to the over-excitation of sympathetic nerves and the over-metabolism; Conversely, patients with hypothyroidism are unable to generate enough heat to keep out the cold due to poor sympathetic nerve function.

There are also long-term smokers, due to the lack of oxygen in the body, the surrounding microvessels are prone to poor circulation, and when the arterial microvessels are not smooth, they are prone to chills; However, if the vein microvessels are not smooth, although there is no special fear of cold, the blood vessels cannot be dilated during activity, and the blood cannot circulate, resulting in local oxygen insufficiency, and the hands and feet are prone to coldness. Urban "lazy people" who usually "don't sit if they can lie down, and don't stand if they can sit", because of the decrease in basal metabolic rate, will also have the problem of not being cold-tolerant.

Fear of cold is due to the weakness of the body, the lack of qi and blood, the weakness of the body's energy, and the lack of yang energy, resulting in the body producing less heat, not enough to warm the body, and you will feel afraid of cold.

How did it come about?

Or they stay up late for a long time, work tired, mental pressure, overdraft, etc., resulting in weakness of body qi and blood.

Or their own stomach and intestines are poor, and their cardiopulmonary function is weak, resulting in poor digestion and absorption, shortness of breath, resulting in insufficient energy for the body from the outside world, so the lack of qi and blood, then the body will be afraid of cold.

To restore it, you need to strengthen your physique, nourish enough qi and blood, enhance your body's energy, increase your yang energy, speed up the flow of qi and blood around your body, and unblock the blocked places in your body, so that your body will have enough qi and blood to get through, so that your body will produce enough heat to warm your body and not be afraid of cold.

There are many reasons for being afraid of cold: people with iron deficiency have less heme, which affects the oxygen-carrying capacity of the blood, resulting in disorders in tissue energy metabolism, and people will feel abnormally cold due to insufficient calories produced; People with low blood pressure have insufficient peripheral blood circulation, and the human body tissues also do not get enough oxygen and energy, and they will also be chilled; In addition, when the secretion of thyroxine in the body is insufficient, the blood circulation in some parts of the body, such as **, slows down, and the lack of heat production will cause a stronger reaction to cold; Menopausal women have low estrogen levels in their bodies, which affects the stability of nerves and blood vessels, and they are prone to chills in the waist, abdomen, hands and feet, and the whole body.

Note that the first thing to check is whether it is possible to have hypothyroidism and whether it is caused by physical weakness, poor peripheral circulation, and autonomic nervous disorders. Of course, there are individual differences. It is recommended to eat more mutton soup, etc. Pay attention to keeping warm and warm.

There are many factors that are afraid of cold, which vary from person to person, and specific problems should also be analyzed in detail. Gastrointestinal dysfunction.

The body has a low ability to dissipate heat, low resistance, and poor cold resistance, so it is easy to feel cold. To solve the problem of cold intolerance, you can also participate in appropriate physical exercise, but also strengthen dietary conditioning, improve the ability to withstand cold, you can eat more foods rich in iodine, zinc, nucleic acids, appropriate supplementation of nutrients, recommend vitamin E and vitamin C, can improve blood circulation; B vitamins promote metabolism; Iron and zinc, which improve anemia and increase metabolic rate. Get enough sleep.

Feel it.

The body is more afraid of cold than ordinary people, because the body is weak, the qi and blood are not sufficient, the yang qi is weak, the body energy is small, and the circulation of qi and blood is too slow, resulting in the body

The body produces less heat, which is not enough to warm the body, and it will be afraid of cold. How did it come about?

The body is overdrawn, such as staying up late, tired from work, etc., and lack of qi and blood.

The body is cold and damp, the meridians are blocked, and the circulation of qi and blood is too slow.

Poor digestion and absorption of the stomach and intestines, and shortness of breathing, lead to the body getting less energy from the outside world and insufficient qi and blood.

To restore it, it is necessary to strengthen the physique, nourish enough qi and blood, enhance the body's energy, speed up the flow of qi and blood around the body, unblock the blockages in the body, and make the qi and blood around the body sufficient, then the body's energy will be enhanced, and the heat generated is enough to warm the body and not be afraid of cold.
