Why are people afraid of cold in winter?

Because the temperature in winter is lower than the body temperature of the human body, if there is no heat preservation measures, the human body is in a state of exothermy, and if it loses heat, it will feel cold, so it is a reason that in summer, it is cooler after taking a hot bath than after a cold bath.

Because people's congenital conditions determine part of their acquired physique, for example, some people are particularly afraid of heat in summer, and this kind of person is generally more resistant to freezing in winter, and your situation may be more heat-resistant in summer. Life care: If there are no other uncomfortable symptoms, it is recommended that you can increase the amount of exercise to improve, because if you want to change your body constitution, not to mention taking medication for too long, many people still can't change it.

It is because humans are animals that are afraid of cold, and they have no defense against cold.

The most direct reason is the cold weather in winter!

If a person with a lot of blood and a weak constitution are afraid of cold.

The main beneficial bacteria or fungi in humans and animals are yeasts, probiotic bacillus, Clostridium butyricum, Lactobacillus, Bifidobacteria, actinomycetes, etc. [2].

1.Yeast: At present, it has been found that yeast has good probiotic properties such as regulating intestinal balance, promoting feed conversion and improving immune function, and is mostly used as a feed additive in livestock and poultry breeding.

The most studied yeasts include Saccharomyces cerevisiae, Saccharomyces delbo, Candida, Wickham's yeast, Pichia pastoris, Saccharomyces boulardii, Saccharomyces spp., Scheva yeast, Crimson yeast, Schizomyces spp., and Bauery's yeast [2].

2.Probiotic bacillus: It is a class of aerobic or facultative anaerobic, spore-producing rod-shaped bacteria with probiotic properties to the body, which is a Gram stain-positive bacterium [2].

3.Clostridium butyricum: also known as Clostridium butyricum, is an anaerobic gram-positive bacillus isolated from the intestines of healthy humans and animals.

At present, studies have found that Clostridium butyricum has good probiotic properties such as maintaining the balance of intestinal flora, enhancing the body's immune function, generating nutrients, and preventing and treating enteritis [2].

4.Lactic acid bacteria: Lactic acid bacteria refers to a class of non-spore, Gram stain-positive bacteria whose main product of fermented sugars is lactic acid. Lactic acid bacteria are the most common probiotics and have been widely used and considered safe for humans and animals [2].

5.Bifidobacteria: It is a physiological bacterium existing in the human body, which is one of the most worthy of attention and research in the beneficial bacteria of the human body, and it is inseparable from the health of the human body.

There are several reasons why you are very afraid of cold in winter:

1. The body is too thin.

Most people who are too thin tend to feel cold, and these people have less fat and muscle in their bodies. Sufficient fat is necessary to isolate from the outside world, and muscles can produce heat. If you are underweight, you don't have enough muscle and fat to fight the cold.

Another part of women will be afraid of cold during childbirth and menstruation, because the estrogen in the body has changed greatly, affecting the nervous system, reducing blood flow, causing subcutaneous blood vessels to constrict, thus causing stomach cold and cold. There are also some women who do not like to move, which reduces the production of calories and poor blood circulation throughout the body, resulting in cold parts such as hands and feet.

2. Iron deficiency in the body.

Almost all people who are afraid of cold have insufficient iron in their bodies, and thyroxine in plasma is relatively low. People with insufficient iron have less heme, which reduces the ability of blood to absorb oxygen, makes tissue metabolic dysfunction, and the body cannot produce more calories and makes people extremely cold. In addition, people with low blood pressure have insufficient peripheral blood circulation, and the tissues of the body do not get enough energy and oxygen**, which will also cause chills.

3. Insufficient thyroxine secretion.

When there is an abnormality in the thyroid gland, the secretion of thyroxine decreases, slowing down the rate of blood circulation, and the heat production is insufficient. Especially in menopause, the low level of estrogen is not conducive to the stability of neurovascularity, which makes the patient have cold waist, abdomen, hands and feet. Because thyroxine has the effect of thermogenesis, it can increase the basal metabolic rate, speed up blood circulation, and increase calories.

Once thyroxine secretion is insufficient, heat production decreases, making people feel cold.

4. Kidney Yang deficiency or Yang Qi deficiency.

Winter chills and cold intolerance may be caused by anemia or kidney yang deficiency, when the yang qi is insufficient, the whole body qi and blood flow is not smooth, and it is not better to let the muscles get warm to resist the invasion of cold evil, and it is easy to feel the body cold. In addition, people who always have cold hands and feet may have qi deficiency or yang qi deficiency, and can reasonably use traditional Chinese medicine to recuperate.

This is generally caused by the weakness of the body's qi and blood, insist on exercising, improve diet, eat more mutton, dog meat, yak meat, angelica, cordyceps, and other high-calorie foods, and when it is serious, you can also use qi and blood tonic drugs to regulate, you can go to the pharmacy to buy qi and blood tonic drugs or use traditional Chinese medicine to recuperate, I wish you not to be afraid of cold as soon as possible, hehe.

The yang energy in the body is insufficient. The human body is divided into yang and yin, and the yang qi is insufficient, and it is common to have cold limbs and clear urine.

In traditional Chinese medicine, it is recommended to adhere to physical exercise to improve body function.

Yang deficiency, the limbs are afraid of cold for spleen yang deficiency, and the whole body is afraid of cold for kidney yang deficiency.
