Why is it easy to catch a cold when it s cold Why do you love to catch a cold when it s cold?

People may not have noticed that the weather is getting cooler, or they may have caught a cold before they have reacted, or even have a fever, so what is the reason for this phenomenon? Perhaps, you will be inspired by the following points.

Because the temperature drops, the body's ability to resist viruses also decreases, and if you don't keep warm, of course, it is easy to be invaded by viruses and cause colds. Part of the important reason for this is that in the summer and autumn, people are still wearing short sleeves, spending the summer, and the autumn rain is down, and they have caught a cold before they have time to change into autumn clothes.

Therefore, we must do the following: First, pay attention to adequate nutrition. Picky eaters or frequent eating out can easily cause nutritional imbalances, and the resistance to colds will be weakened.

Therefore, it is necessary to take a balanced intake of various yin and yang substances, etc., and drink plenty of water. Second, get enough sleep. Sleep can regulate the body's immune function, and the sleep time of office workers should be no less than six hours, and the sleep time of students should be no less than eight hours.

Third, you should maintain personal hygiene, and no matter what others do, you should pay attention to your own personal hygiene, as the saying goes: trouble comes from the mouth, illness comes from the mouth, only by taking care of your own hygiene, you are qualified to manage others. Fourth, wash your hands frequently and avoid going to crowded places.

Wash your hands frequently every day, as the virus is most likely to be contracted through the touch of your hands. When coughing or sneezing in a public place, cover your mouth and nose with a handkerchief or tissue to prevent droplets from splashing and spreading germs. Once you catch a cold, try to rest as much as possible and do not go to crowded public places to avoid cross-infection.

Fifth, rinse your mouth with salt water. Rinsing your mouth with salt water every morning and evening and after meals can remove oral germs, and brushing your teeth twice a day is not enough. It is also very necessary to rinse your mouth at the right time.

Sixth, keep exercising. Exercise can help people reduce stress, maintain a happy mood, maintain a healthy state, and reduce the chance of catching a cold.

The above points are how to prevent colds when the weather is cooler. In other words, when the weather is not cold or hot, don't you need to prevent colds? In fact, regardless of spring, summer, autumn and winter, we should always prevent colds all year round, but autumn and winter are the high incidence season of colds.

There are several main reasons: in autumn and winter, the weather becomes cooler, and people stay in the classroom or at home due to fear of cold, and the air cannot circulate well, so they are naturally prone to colds; There is also people's inertia, because the weather is too cold, they don't like sports, and they lack the most basic physical exercise, and their physical fitness will decline, so it is a matter of time before they catch a cold.

In short, when the weather gets cooler, it is a time when diseases are frequent, that is, it is easy to catch a cold, and we must do a good job of protection and prevention for the sake of ourselves and the health of others.

I've had a cold recently, and now in autumn, the weather is a little unstable, with a large temperature difference between morning and evening, and for the weather in the north, it will be warm at noon. If you are dressed in a bad way, you may suddenly catch a cold. I just obviously wore less in the past two days, I didn't listen to my dear mother's words, I feel that it's only September now, and the sky outside is still sunny in the house, ** with too much clothing, but, in fact, it looks warm outside, but it blows really cool breeze, so I "don't listen to the old man, suffer in front of me".

Infection with each other, the weather is cold, if someone in the family has a cold, or a colleague in the unit has a cold, and it happens that your body immunity is not so good, then it must be infected, so, when the weather is cold, when you just want to have the symptoms of runny nose, just take some cold medicine to prevent it, and wait until it is really a cold, nasal congestion, sore throat and head are confused, then it is only uncomfortable, and I summarized that the general cold cycle generally lasts about 7-10 days. Obviously things that can be prevented before they happen, but you have to wait for it to happen and then make up for it, who do you say can blame for this, you can only blame yourself for not taking good care of yourself.

I feel that the so-called cold weather is the kind of cold weather that alternates the seasons is the most likely to make people sick, the family remembers to keep the room ventilated regardless of spring, summer, autumn and winter, so that the indoor is always flowing fresh air, some people will ask, "in the winter, open the window is to freeze people", I didn't say let you open it for a day, you can open it intermittently, breathe fresh air, or when the flu is frequent, it is also good to spray some vinegar in the house to disinfect. However, in the morning, I feel that I must open the window to let the smell in the house, so that the air in the house starts to be fresh from the morning, why, because you want to be at night, it is impossible not to exhaust, it is best to turn over the quilt and open the window to disperse the smell of the fart inside, and then fold the quilt, so that the quilt also absorbs the fresh air.

If you have already started a family, it is recommended to prepare a medicine box at home to stock up on some medicines for colds, fevers and headaches, because if you have a fever in the middle of the night, you can eat it directly, so you can be prepared. If you can take medicine, don't go to the injection, think about how painful the injection is, anyway, I'm afraid of pain, I usually take medicine for a meal, and I know how to wear more when I have a cold, and I wear a lot of clothes today, I can't wait to put on all the fleece pants, maybe the body will need more calories when I have a cold.

So, if you are sick, if you are sick, you should wear more and wear more, and you should prevent it.

You don't love to catch a cold when it's cold, but you love to catch a cold when the air is dry in winter. The air is dry, and cold viruses float in the air and are easily inhaled into the nasal passages. It is also easy to fall on objects and get touched by your hands, and if you touch your nose and eyes with your hands that are stained with cold viruses, you can get cold viruses into your nasal cavity (the cold virus that enters your eyes will enter your nose along the tear ducts) and cause a cold.

In the past, people all over the world will find out that they have a cold because people have symptoms of fear of cold and shivering, and they mistakenly think that it is cold that causes colds, and scientists will carry out research to see if there is a causal relationship between cold and cold, experimental studies have shown that colds have nothing to do with cold, wind, rain, bacteria, etc., only the nasal cavity into the cold virus can cause colds.

In other seasons, dry air is also easy to cause colds, and dry indoor air (especially in winter) is more likely to cause colds, because many people have closed indoor doors and windows in winter, and lack of ventilation will cause cold viruses to gather, plus dry air cold viruses float in the air. Therefore, to prevent colds, keep indoor ventilation, moist air (cold viruses can be pressed on the ground), wear masks when the outdoor air is dry, do not develop the habit of picking your nose and rubbing your eyes, and wash your hands frequently.

Hello! According to scientists, cold weather is easy to catch a cold because people reduce outdoor activities and stay in closed and warm rooms, which makes cold viruses more easily spread from person to person, so there is no direct relationship between cold viruses and hot weather.

It's cold, it's easy to catch a cold, and then you catch a cold, and winter and autumn are the seasons for that kind of viral flu outbreak.

In general, a cold may be caused by aggravation of cold symptoms, changes in core temperature, complications, etc., as follows:

1.Aggravation of symptoms of early hem: When the patient's immunity is weakened, it may be attacked by the virus and cause a cold, and with the development of the disease, the patient's cold symptoms may gradually worsen, so that the capillaries will constrict, resulting in a drop in temperature, and then there may be symptoms of cold and cold.

Patients can use medicines such as Cold Qingre Granules, Cold Shufeng Capsules, and Banlangen Granules under the guidance of doctors**.

2.Changes in core body temperature: After a cold, the virus may invade the body temperature regulation center, which can easily lead to abnormalities in the thermoregulatory system, causing changes in core body temperature, causing symptoms such as fever and chills, which may cause patients to feel cold when they catch a cold.

Patients can use acetaminophen tablets, aspirin tablets, ibuprofen extended-release capsules and other drugs under the guidance of a doctor**.

3.Complications: Feeling cold can be a complication caused by a cold, and patients usually have a fever after a cold, and with the evaporation of body fluids, patients may experience chills. Patients are advised to keep warm, drink plenty of hot water, and promote fluid circulation.

Feeling cold after a cold can be caused by something like a fever or a viral infection.

1.Fever: Fever is mainly divided into the period of rising body temperature, the period of continuous fever, and the period of falling body temperature. For example, during the period of rising body temperature, the body temperature setting point moves upward, which will cause the body to chill and cause the muscles to contract involuntarily.

2.Viral infections: Colds are related to bacterial and viral infections, such as those caused by viruses. Clinically, the virus will affect the regulatory center of body temperature, and the source will also release many toxins, resulting in an increase in body temperature and chills.

In addition, other conditions will also cause you to feel cold after a cold, so you should go to the hospital for examination in time, and after clarifying, you should deal with it accordingly under the guidance of a doctor.

There are several reasons why you feel cold when you have a cold:

Immune response: Cold viruses cause an immune response in the body, which causes an increase in body temperature. When the body temperature rises, the body will dissipate heat by sweating and other means, so that the body temperature will return to normal. In the process of heat dissipation, the temperature of the body surface will drop, resulting in a feeling of cold.

Cold virus multiplication: Cold viruses release heat when they multiply in the human body, but usually this heat is not enough to offset the heat loss inside the body, so it can make the body feel cold.

Vasoconstriction: When you have a cold, the body will reduce the blood flow to the muscles by constricting the blood vessels, thereby reducing the heat dissipation on the body surface. This causes the temperature of the body's surface to drop, making it feel cold.

It should be noted that feeling cold when you have a cold is only one of the symptoms, if the symptoms are more severe or last for a long time, it is recommended to seek medical attention in time, and friends and grandchildren can be diagnosed and ** in time. At the same time, it is necessary to inject fiber to keep the spine warm and avoid catching a cold.

Because the weather is cold, the mucous membrane of the human body is very sensitive to temperature, as soon as the human body is cold, the nasal mucosa and the mucosa of the respiratory tract will shrink, the movement ability of the motor cells will be weakened, and the lysozyme secreted by the human body will also be reduced, at this time, the bacteria and viruses living in the human nasopharynx and respiratory tract will take the opportunity to grow, and then people will have a cold.

Wind and cold disease, the wind evil invades the human body, the human body is not full of righteousness, the good is invincible, and the evil qi of the body enters the body, there will be diseases, and the common one is a cold.

Cold will not catch a cold, the simplest truth, colds are all about the upper respiratory tract, no matter how much you wear your nose and mouth to have chicken feathers?

Sensitivity to cold is a typical manifestation of insufficient yang energy, and the cold in the body is very heavy, so it will be afraid of cold. When the wind blows, it needs to take away the heat of the body, so it will feel even colder, and the cold when the wind comes will make people feel weak.

Suggestions: You can choose Jinkui Kidney Qi Pill**. Eat more iron-rich foods such as liver, lamb, fish, eggs, black fungus, milk, legumes and green leafy vegetables. Eating more iodine-rich foods such as kelp, fish, shrimp, and oysters can improve the ability to protect against the cold.

This phenomenon is the phenomenon of qi deficiency, the qi of the human body is like a protective umbrella according to this traditional Chinese medicine, you are not afraid of cold and heat if you are full of qi, and you are not tolerant to cold and heat if you are deficient, so if you want to replenish qi and blood, you can eat some calcium gluconate, which can stop sweating, and at the same time, you can eat some tonifying qi pills and jade screen powder to replenish qi, and it will be fine.

What is the reason why you are afraid of cold and easy to catch a cold? Hear what the experts have to say.

Netizens asked: Why do people do Du when they have a cold?

Feeling cold? Zhi @负二: This is the body's response to the viral version of the attack, the increase of endogenous pyrogens in the brain (commonly thought to be PGE prostaglandin E, but also said to be the increase in the ratio of Na+ Ca2+ in body fluids that leads to increased cAMP in the brain) interferes with the reactivity of the hypothalamus thermoreceptor nerves.

Most antipyretics reduce body temperature by preventing the formation of endogenous pyrogens. @曹新彬: The first thing to do when a cold causes the body's self-protection function to run is to speed up the enzymatic reaction.

In order to strengthen the efficiency of enzymes in the human body and make the environment of enzymes more suitable, the body temperature will rise. The ultimate consequence of an increase in body temperature is that you feel like the environment outside is getting colder. Actually, it's ...... you have a feverLong Yang:

According to popular science programs, the human body does not have temperature receptors, and can only feel the speed of heat loss and absorption, so people cannot feel the absolute temperature value, but can only feel the direction and speed of heat transfer. So it feels colder than usual, which can only mean that the heat is dissipated faster than usual.

When you have a cold, there is a basis for feeling cold no matter how many layers of quilts you have, so come and take a look.

According to the second law of thermodynamics, heat will spontaneously flow from a hot object to a low temperature object, if the temperature rises, the temperature difference between the inside and outside will be greater, Fourier's law indicates that the larger the temperature difference, the faster the heat flow, and the colder it feels.
