What are the main causes of winter colds???

The cause of winter colds is usually due to a change in temperature that causes the body to get cold, resulting in a viral infectionAs the saying goes, spring covers autumn frost, and many young people have pursued the concept of demeanor rather than temperatureWhen there is a temperature difference in winter, the human body is easy to get cold, which will reduce the local immunity of the respiratory tract, and the virus will easily invade the respiratory tract, which will lead to colds.

Common ways to prevent colds are as follows:

1. Pay attention to keeping warm: you should increase or decrease clothes in time to maintain good health, and remove the triggers that cause cold, so that you are not easy to catch a cold;

2. Avoid exertion and staying up late: Fatigue and staying up late will also make the body's immunity low, leading to the occurrence of viral infection. Because it is easy to get cold in winter, if you are tired and cold, colds are more likely to occur;

3. Strengthen physical exercise: Strengthening physical exercise is an effective way to improve immunity, and studies have proved that aerobic exercise can improve the body's immunity.

4.Wear a mask and wash your hands frequently: In your daily life, especially when you are away from home, you must remember to wear a mask, wash your hands frequently when you are fine, ventilate your home more, and keep the indoor air fresh, which can reduce the impact of the flu on you.

In the south, temperatures fluctuate during the change of seasons, causing a variety of viruses to multiply, which is a direct cause of people's susceptibility to illness at this time.

Studies have shown that rhinovirus and coronavirus are the two main causes of the common cold. They breed in large numbers when the weather is cooler, such as in spring and autumn. Similarly, influenza viruses replicate and spread most rapidly when the air is cold and dry.

As a result, people are susceptible to influenza at the turn of winter and spring.

The occurrence of the disease at the turn of spring and summer is related to a variety of factors. Sometimes, people may mistake allergies for a cold. People with seasonal allergies often experience nasal congestion, and these people have runny noses and itchy eyes when they are near pollen, mold, and grass.

In addition, when exposed to these allergens, the immune system overdrives, making it more susceptible to viral infections.

Extended Information: Things to Note When Changing Seasons:

1. Prevention of spring cold: The so-called "when it is warm and cold, it is the most difficult to breathe", and the sudden change in temperature caused by "spring cold" does have various adverse effects on human health.

For example, cardiovascular and cerebrovascular diseases, cold and cold, rheumatoid arthritis, respiratory diseases, etc., therefore, when there is a "spring cold", it is also the time when the incidence of respiratory infectious diseases such as measles, whooping cough, scarlet fever, and bronchitis is the highest, and special attention needs to be paid to prevention.

2. Fire prevention: The sun is shining in spring, the spring breeze is rippling, and everything is recovering, which is suitable for going out for picnics. However, the fire prevention work of going out for outings and picnics cannot be ignored. Not all wilderness is suitable for barbecue, so it's important to choose a place for a picnic.

It is best to choose a place with good scenery and convenient transportation. Since you want to make a fire, it is better not to go to the mountains, nor in the woods, it is better to be near the river or a sandy river beach, and there should be no flammable materials around the downwind outlet. Do not choose closed places such as caves and rooms for barbecue to prevent carbon monoxide poisoning.

In case something is burned, you can put it out by taking a bucket of water nearby. When the fire is finished, be sure to extinguish the fire.

Cold weather can alter the outer membrane of the influenza virus. It makes the outer membrane of the influenza virus stronger and rubbery. Scientists believe that rubber coatings can make it easier to spread viruses from person to person.

A study by Yale University in the United States found that a key factor why influenza viruses are more transmissible in autumn and winter is low humidity. The researchers found that low humidity makes the cilia of respiratory tract cells less effective against influenza viruses, and that the virus can cause lung damage, which reduces the ability of respiratory cells to repair this damage under low humidity conditions.

In winter, most people spend less time outdoors and lack light, and sunlight is the main source of vitamin D, which is essential for the health of the immune system.

The cold climate in winter will reduce people's time for outdoor physical exercise, and the lack of exercise will reduce people's resistance and easily cause colds.

In winter, the time spent outdoors is too short, on the contrary, the time spent indoors will be longer, some people are afraid of the cold and do not ventilate frequently, if it is a densely populated office area, the contact between people is closer, which is more likely to lead to the spread of the virus. Respiratory viruses can usually spread within less than 2 meters of an infected person. Drying out the mucous membranes of the respiratory tractCold weather can dry out the mucous membranes of the eyes, nose and throat, inhaling the virus that causes colds and flu when breathing, so the virus can more easily attach to these damaged dry passages, causing colds.

It is easy to catch a cold in winter because the climate is relatively cold in winter, and the human body is susceptible to the invasion of wind and cold and cold.

The common symptoms of winter colds include nasal congestion, runny nose, cough, cough with white phlegm, etc., ** on the main divergent wind chill, commonly used drugs include: Chinese patent medicine wind cold cold granules, Tongxuanli lung tablets, cold and heat clearing granules and Jingfang granules, etc.; Western medicines include aminophen pseudoephedrine tablets, compound pseudoephedrine hydrochloride sustained-release capsules, compound aminophenamine capsules, etc., while taking oral medicines**, it is also necessary to take warm measures to avoid catching a cold again.

The number of people who catch colds in winter is mostly related to the influence of climatic factors, crowd clustering, disease contagion, and low autoimmunity.

1.Climatic factors: Winter is an important cause of respiratory diseases due to the cold climate, and the cold season can induce bronchial diseases.

2.Crowd clustering and disease contagion: the cold itself is contagious, and it is infected through coughing, droplet and saliva.

3.Low autoimmunity: The elderly, frail, young children and other people are prone to colds and other diseases due to their low autoimmunity. In winter, it is necessary to drink plenty of warm water, strengthen care and keep warm, and avoid cold.

If you have symptoms of a cold, you need to go to the hospital and take oral medicine under the guidance of a doctor. The patient's experience of cold and wind-heat cold is timely**about a week**, and special attention should be paid to it during the epidemic.

In the south, it is easy to catch a cold in winter and spring, mainly because the temperature is low in winter and spring, we are prone to cold and cause cold, at this time, the body's immunity is poor, and bacteria or viruses are easy to take advantage of the weakness to cause colds. In addition, the temperature in winter and spring is relatively low, which is conducive to the survival of the virus and causes colds. A cold can cause a series of respiratory symptoms, such as headache, dizziness, cough and phlegm, nasal congestion, runny nose, and even fever.

We can do some sports to prevent colds, improve immunity, enhance physical fitness, and also prevent some other diseases. Eating more vitamin-rich fruits and vegetables is also conducive to improving our immunity and reducing the incidence of diseases. In addition, when the weather is cold in winter and spring, we should also pay attention to keeping warm.

Frequent colds in winter are very related to not paying attention to keeping warm, so in the case of cold weather, you must pay more attention to wearing warm clothes and do a good job of keeping warm, so that it will be better.

In daily health preservation, we must learn more from professional personnel, master the good way of health preservation, and learn the methods of communicating words and standardized use with others, and pay attention to the following points.

1 The scope of the meaning of the word varies.

For example, "reclamation, development, and development" all have the meaning of "development", but "reclamation" refers to the vigorous development of barren land into arable land; "Pioneering" means expanding on the basis of the original development; The word "development" focuses on new development and new creation, and the meaning of the word is large.

2 The emphasis of the meaning of the word is different.

For example, "talent" and "talent" both contain the meaning of ability and specialty, but "talent" focuses on the ability to do things or the ability to use knowledge, skills, and techniques, while "talent" focuses on the wisdom and expertise revealed in literature and art; Both "discovery" and "invention" have new meanings, but "discovery" focuses on finding something that already exists, while "invention" focuses on creating something that doesn't exist in the first place.

3 The meaning of the word is different.

For example, "damage" and "destruction" both have the meaning of destroying objects, but "damage" is generally unintentional, and "destruction" is intentional; "Slander" and "false accusation" both mean to insist that someone else has done something bad out of nothing, but the former is to fabricate facts and damage others' reputation, while the latter is to falsely accuse and frame others, and the severity of the two is different.

1. Not paying attention to personal hygiene.

If you don't pay attention to personal hygiene in your daily life, you are prone to catching colds frequently. Our hands come into contact with a variety of objects every day, and there are many germs in these objects. If you don't wash your hands in time to eat, or touch your mouth or nose, it is easy to cause these germs to enter the body, and it is easy to catch a cold often.

2. Don't pay attention to keeping warm.

If you usually pay attention to keeping warm, you always don't want the temperature as long as the demeanor, and it is easy to catch a cold often. Especially at the turn of the seasons, or when you go out at night, if you don't add clothes in time, it is easy to cause the cold to invade the body and reduce the resistance. In particular, if you don't pay attention to the warmth of your feet, you are most likely to catch a cold.

The feet are a part of the heart, especially in winter, the blood will be relatively low, and once the feet are cold, they will cause frequent colds.

3. High mental pressure.

If the long-term pressure is too great and excessive fatigue will easily lead to imbalance in all aspects of the body, resulting in a decrease in immunity, and it is easy to catch a cold frequently. Therefore, in ordinary life, we should pay attention to the combination of work and rest, and don't work too hard. It's good to maintain a good attitude and learn to relieve stress properly.

4. Poor diet.

A long-term diet is very important, and it is important to pay attention to the comprehensiveness of nutrition. Especially for the sake of growing the body, it is necessary to pay more attention to the supplement of various nutrients. When the work is heavier, the body's consumption will also increase.

If you eat too poorly, it will lead to malnutrition, poor physical fitness, and frequent colds. In addition, if you often eat some high-protein objects and eat too salty, you are also prone to frequent colds.

The root cause of a cold is the invasion of cold viruses or bacteria into the body. Like blowing the wind, a little cold only reduces the body's resistance, and cold germs will take advantage of the weakness. The reason why you often catch colds is also because your resistance is too poor.

The symptoms you are exhibiting are because your brain is fully controlling the body's mechanisms to fight against germs, so you are dizzy and unable to beat your spirits; After a cold, the digestive ability is weakened, the appetite is reduced, and the elimination of germs consumes a lot of energy and nutrients, so the whole body is weak.

There is no point in taking medicine and injections for colds, it is generally to relieve the symptoms, treat ***, and make people feel more comfortable. If you use too much, you will also develop resistance and reduce your resistance. Unless it may be a poultry flu, pig flu, etc., take less injections and medicines.

Because most of the viruses are parasitic in human cells, with strong drug resistance and many variants, there is no drug in the world that can effectively and directly kill the cold virus in the body, so it is of little significance to take injections and medicines, and it is the next policy.

Prevention of colds is the main thing, and to prevent colds, you should exercise regularly, and you should also pay attention to less contact with people who have suffered from colds, which will be infected. Put an end to bad habits and ensure physical fitness. Drink plenty of water to dilute toxins in the body and speed up metabolism.

Eat more fresh fruits and vegetables and supplement vitamins. Pay attention to rest, excessive fatigue will also lead to a decrease in resistance, and germs will take advantage of the weakness. Vitamin C and VC supplementation can promote the production of immune substances such as lymph, interferon, CI, collagen, etc., inhibit viruses, heal wounds, and enhance resistance.

In case you catch a cold, drink plenty of water, rest, vitamin C supplements, and exercise appropriately, such as walking and doing exercises. Don't do strenuous exercise, it will consume a lot of nutrients and water, which is not conducive to**. Pay attention to heat preservation to prevent further loss of resistance after cold.

Also, keep your mindset and be positive and optimistic in the fight against colds, believing that victory is yours.

The above points are carried out at the same time, which is definitely faster and more effective than injections and medicines.

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.
