The cold winter is the period of high incidence of colds, why is it easy to catch colds in cold wint

Catching a cold in winter can be caused by seasonal allergies, viruses, and wind evils.

1.Seasonal allergies occur in the body, and in winter, the patient's tracheal mucosa is very sensitive to temperature differences, and colds may occur. The main symptom is a runny nose and, in severe cases, headaches.

2.When a virus, rhinovirus or parainfluenza virus invades the body, you may catch a cold. In the beginning, the patient usually has a cough and runny nose, and in severe cases, the patient may also have watery eyes and a dull sense of taste.

3.Wind evil, in winter, the weather is cold, wind evil can cause wind chill cold. In the early stage, you may have symptoms such as runny nose and nasal congestion, and in severe cases, you may have difficulty breathing and cough up a small amount of phlegm.

Patients with symptoms such as frequent sneezing and runny nose can be treated with antihistamines** such as loratadine and cetirizine, and patients with more severe disease can be treated with antipyretic analgesics such as aspirin and ibuprofen.

Because at this time, people's resistance will become worse by 1 point, and because the weather is cold, the cold is easy to invade the body, and then make people catch a cold and catch a cold.

Because in the cold winter, the temperature is very unstable, and the temperature is constantly changing. Frequent cooling is fought. It's easy to catch a cold.

Because the temperature in winter is particularly low, people's immunity is relatively low, so they are particularly susceptible to colds.

Because the weather is cold in winter.

Preface: The temperature changes rapidly in winter, and the temperature difference between morning and evening is relatively large, so we must wear more clothes when we go out in the morning. At the same time, to improve the body's resistance, the probability of cold in winter is still very high, we must pay attention to our body.

Only if you have a healthy body, it will be easier to deal with difficulties in work and study. Let's share with you how to prevent colds in winter.

Because the weather is very cold in winter, everyone must pay attention to keeping warm. We don't pay attention to the demeanor, not the temperature. In the winter, wear more clothes, although many people dress like a bear, but we don't have to worry too much about our appearance.

Only keeping warm is the most important thing, and we must put our body first. Once inside, we can take off our thick clothes. When you go out, be sure to prepare a hat and scarf to protect your body and keep warm, so as to prevent colds.

We can observe that if it is a person who is physically weak and has low resistance. When the weather turns cold, it is very easy to catch a cold, so we can improve our resistance. When resting, everyone should go out to exercise, pay attention to rest, and sleep more than 8 hours a day.

Develop good living habits and don't play with your mobile phone all the time, the radiation of your mobile phone is very large, and it has caused some damage to your eyes. At the same time, it is recommended that we drink a certain amount of water every day, which not only improves the body's metabolism, but also eliminates toxic substances.

At night, if you want to achieve better sleep quality, it is recommended that you soak your feet in hot water. Soaking your feet in hot water can not only increase the speed of blood circulation, but also allow us to fall into a deep sleep state faster. Therefore, in winter, you must prepare a foot soaking bucket and soak your feet every day.

In spring, you should pay attention to the cold and keep your body warm, wear more clothes, pay attention to the ventilation of doors and windows, wear a mask when you go out, and take some medicine to prevent colds.

First of all, we must pay attention to the diet, we must eat a light diet, we must not eat too greasy, we must eat more fresh vegetables and fruits, such as apples, bananas, oranges, oranges, grapefruits, lettuce, greens, tomatoes, carrots, cucumbers and other foods, and we must also pay attention to the routine of work and rest, do not stay up late.

Avoid contact with the source of infection, keep a distance of more than one meter from people with colds, because the virus in the nasal cavity will fly to a distance of more than one meter when sneezing, and when the bus, subway, elevator and other relatively closed can not leave, you should turn around and avoid direct contact, because people's eyes and nose are the most susceptible to infection.

Prevention of colds: Colds are a common and frequent disease. Prevention of colds is more important than **. The focus of prevention should be on daily health care. 1. Pay attention to cold and warm. When the human body is cold, the blood vessels of the respiratory tract are constricted, and the blood ** is reduced.

Winter colds are indeed very easy to occur, you should pay attention to keeping warm, usually you can drink more brown sugar ginger water, can warm up.

The high incidence of colds in winter is mainly due to the cold weather and the lack of timely ventilation in the room. In spring, to prevent colds, you should add clothes in time, and don't think that you can reduce your clothes when the weather gets warmer.

A cold is actually an upper respiratory tract infection, which is generally caused by a virus. The reason for it is said is only to show that antibiotics that only kill bacteria will not work for colds. The cold medicines sold now, many so-called "anti-inflammatory drugs", these drugs are antibiotics, and the simple use of antibiotics in the process of **cold** not only can not play any ** role, but also is very likely to increase adverse reactions and create bacterial resistance.

Since the beginning of winter, the climate is abnormal, which provides an opportunity for the virus to multiply, coupled with the large temperature difference and other reasons to induce the virus to rise, and the human body's immunity to the virus infection is weak and the time is shorter, so the winter cold is more frequent.

Choose safe and effective antiviral** impulsive drugs. Amantadine is currently the only antiviral cold ingredient recognized by the medical community, which has the effect of quickly killing the influenza virus, and is known as the nemesis of the influenza virus by the medical community. Containing amantadine, there are crack capsules, etc., which are mainly used for colds, and can quickly relieve a variety of complications caused by colds, such as nasal discharge, cough, fever, sore limbs and other symptoms.

Crack capsules do not contain PPA, caffeine and other substances, which is safer and more effective for the human body.

First of all, because in the cold state, the resistance of our respiratory tract is reduced, and it is more likely to be invaded by viruses; The second reason is because of these viruses that cause our respiratory infections, which are in cold environments; It reproduces more vigorously. So in this case, our upper respiratory tract infection is mainly a viral infection.

It is easy to catch a cold in winter, which means that the body is slightly weaker, and you can start with the following small methods.

1. First of all, you must pay attention to keeping warm, and you can prepare a coat in your bag at any time to prevent you from getting cold when you go to work;

2. Low-intensity outdoor exercises can be carried out appropriately on Saturdays and Sundays, such as climbing, jogging, badminton and other sports are very good aerobic exercises.

3. The room should be kept ventilated, you can open the window in the morning and ventilate for 15 minutes;

4. You can usually consume more fresh fruits and vegetables and some nutrients, soulful is a milk powder in Australia, and it is also the choice of many friends at present, which is not only convenient, but also can supplement the body with various vitamins and minerals.

Because the weather becomes cold in winter, some viruses begin to multiply, and the weather is cold, some people do not like to exercise, and the body's resistance decreases, which can easily lead to frequent colds.

In this case, it is mainly considered that the patient's immunity may be weakened or the cold caused by the wind and cold, and it is recommended that the patient can regulate through diet and exercise. Usually eat more protein-rich and vitamin-rich foods to enhance physical fitness and improve resistance.

Winter colds can be caused by seasonal allergies in the patient's body, viruses and wind evils.

The frequent occurrence of colds is due to the fact that the weather changes greatly, so it is easy to catch colds, so pay attention to climate change and reduce the chance of colds.

Colder weather also makes people's immune systems produce fewer antibodies to fight viruses, which weakens their self-protection mechanisms and makes them more susceptible to viral infections.

In winter, the weather is cold, and everyone is reluctant to go out and open the windows. As a result, you will be kept in a closed space for a long time, and viruses and bacteria will be kept in the house. If someone in this space catches a cold, it's even more dangerous.

Therefore, it is also necessary to open windows for ventilation in winter to maintain indoor air quality.

The uncertainty of the weather is accompanied by bacterial infection, it is easy to catch a cold, drink more hot water in dry weather, and use excretion and detoxification to prevent colds.

It's easy to catch a cold in winter, why is it easy to catch a cold in winter?

Because when it's cold, people usually want to stay indoors, and if they don't get exposure to the sun, their bodies will be deficient in vitamin D. And the probability of contracting a cold virus in an enclosed space has increased significantly. Dry air can dry out a person's mucous membranes and make colds worse.

Cold winter air increases the prevalence by reducing the ability of cells in the nasal cavity to respond to invading viruses. Winters are cold and windy, so people are susceptible to the cold. After the body cools down, the resistance weakens, and the virus takes the opportunity to move around.

Colds are mainly contracted through the air When a sick person coughs or talks, small saliva particles are sprayed into the air from the mouth, and these small saliva particles contain countless viruses that can cause colds when others breathe. These viruses may be temporarily hidden in people's noses and throats and will only prevail when people's bodies are weakened. It's too cold outside in winter, and people always like to live indoors, so they need to close their doors and windows to keep them warm indoors.

Because people are concentrated indoors, there is poor ventilation, which creates favorable conditions for the virus to spread from person to person. To prevent colds, you must first exercise one by one. In particular, it is necessary to improve the body's resistance to cold.

Taking cold and cold baths regularly is a great way to exercise your hardiness.

Cold water for the face can be washed every day and is easy to stick. Cold baths must be carried out gradually in a certain way. Every summer, the time is extended from 5 minutes to 1 minute, and after washing, you can wipe your body with a dry towel.

The cold is the most common respiratory disease and is an exogenous disease. If a person's body is weak, life is chaotic, and external evil takes advantage of the weakness, they will catch a cold, young people will have symptoms such as fatigue, runny nose, cough, etc., and severe people will have fever, sore throat, etc. There are four types of colds: cold, cold, cold, cold, and cold.

Different types of colds require different medications**. Colds are not painful. Symptoms such as nasal congestion, sneezing, coughing, headache, etc., must be endured.

It can be said that it is painful.

Because the temperature is particularly low in winter, the body's immunity will also be reduced, and the temperature difference between indoor and outdoor temperatures is relatively large in winter, so it is easy to catch a cold in winter.

It is necessary to consider immunocompromised allergic rhinitis, which can cause cold-like nasal congestion and runny nose. First of all, we should pay attention to eating more vegetables and fruits that contain more vitamins and trace elements, drink more water, exercise properly to improve immunity, pay attention to avoid contact with cold air, and try to go out as much as possible. If they go out, they must wear a mask.

Colds are prone to occur in winter, mainly related to the characteristics of pathogenic microorganisms. First of all, colds are mostly caused by the invasion of viruses in the body, and in winter, the temperature is low, the weather is too cold, the doors and windows are often closed indoors, because the air is not circulated for a long time, it is easier to create a favorable environment for the breeding and spread of viruses, and then cause the occurrence of colds.

Early winter is the season when the common cold is more common, and common cold viruses are easier to breed in a cold environment, and the cold weather in winter makes our immune system produce less anti-viral antibodies, and the protective mechanism is weakened, and it is easy to be infected by the virus.

That's because the weather is cold and windy in winter, and people are susceptible to cold. After the body was cold, the resistance weakened, and the virus began to take advantage of the opportunity to move aggressively.

Because the weather in winter is very cold, people are homeothermic animals, and they are prone to lesions when exposed to too much cold air.

The air is dry in winter. There is a large difference between the indoor temperature and the outdoor temperature, which can easily cause respiratory infections.

In winter, the weather is cold, and the indoor temperature in the north is more than 20 degrees above zero, while the outdoor temperature is more than 20 degrees below zero, and the temperature difference is too large and easy to rise.

A cold is a common cold that we hear about – coughing, sneezing, runny nose, breathless nose, itchy throat, loss of appetite, general weakness, sensitivity to cold, and even fever.

A cold is an infectious disease caused by a filtering virus that is smaller than bacteria and invisible with a normal microscope. Because the lesion is mainly in the upper respiratory tract - nose, throat, trachea, etc., it is also called respiratory tract infection in medicine. Colds are very contagious, and if one person in the family catches a cold and does not pay attention to isolation, it can be passed on to the whole family.

When a person with a cold coughs or sneezes, they spread saliva containing the filtered virus into the surrounding air. So, does everyone who has been exposed to a sick person get infected? Not really.

Some people are safe even if they eat, study and work together with a cold patient all day, because they have stronger resistance.

Colds can be contracted all year round, however, they are most likely to occur in winter, especially when the temperature drops suddenly. Because the climate suddenly becomes cold, the human body has not been able to adapt to this change all of a sudden, and if you don't pay attention to keeping warm, your clothes will be cold if you don't add them in time. When the surface of our body is cold, the blood vessels in the mucous membrane of the upper respiratory tract will constrict, so that the local resistance will be weakened.

As soon as the resistance is weakened, pathogens can take advantage of the opportunity to invade. In addition, people like to stay in heated houses in winter, and even if there is no heating in the home, it is always much warmer indoors than outdoors. Coming out of a warm place and suddenly inhaling a large amount of cold air, the physical and chemical state of the mucosal tissue of the upper respiratory tract is changed, and pathogens are easy to multiply on it.

So, in the winter we are prone to colds. However, this is only an objective reason, a secondary factor. Whether you have a cold or not is mainly determined by the person's resistance.

Who is susceptible to colds? One is that people who usually lack exercise have poor ability to adapt to sudden changes in temperature. The second is people with chronic lesions in the mouth, nose and throat, such as chronic tonsillitis, chronic rhinitis, etc., and these people have poor local resistance to the upper respiratory tract.

The third is people who have been ill for a long time, their bodies have not fully recovered, and their whole body resistance is poor.
