You won't catch a cold in summer?

Guide:?

Recently, the sun was so vicious that blacks were badly sunburned, and the weather was so hot that African friends fainted from heatstroke, but in such a hot summer, many people around them caught a cold. ?

It's so warm in summer, how can you catch a cold? Is this what we often call a cold? ?

Influenza, viral cold, wind-heat cold, wind-cold cold cold ... Xiao Leng has so many names. ?

In fact, it can be divided into two categories: flu and common cold. Among them, influenza, referred to as influenza, is a disease caused by influenza virus, which often occurs in autumn and winter. The common cold can occur all year round, which is called "cold" by Chinese medicine. What we commonly call "cold" refers to the common cold in summer, and many doctors also call it wind-heat cold, as opposed to wind-cold cold cold in winter. ?

Is there any difference between a cold in summer and a cold in winter? ?

In ancient books, the description of cold is like this: Volume 1 of Chishui Zhu Xuan records "cold, cough, sore throat and hot face." "Treatment of Cold Based on Syndrome Differentiation" records "cold, cough and sore throat, stuffy nose and spitting." Namely stuffy nose, sore throat, cough, etc. This is exactly the same as the symptoms of a cold in winter, which also shows that a cold is really a common cold. ?

Will you be "frozen" in summer? ?

In winter, freezing is a very common factor inducing colds, but it is not the direct cause of colds. ?

Maybe you have heard the saying, "A cold is caused by a virus", which is actually true. About 30%-50% of the common cold is caused by various rhinoviruses, in addition to coronavirus and adenovirus. ?

These viruses usually live in our upper respiratory tract, but we won't suffer from upper respiratory tract infection all the time, because our immune system plays a very good protective role. When immunity drops and we can't resist the virus, the virus will multiply in our upper respiratory tract and cause infection, and we will catch a cold. ?

This pathogen often exists, and only under certain circumstances will it cause diseases, which are called conditional diseases. ?

The conditions that cause our immunity to decline and cause colds include the inevitable "freezing" in winter. If you don't keep warm enough in winter, the body will reduce the blood delivered to the skin and limbs in order to maintain the temperature of the brain and internal organs. As blood is transported to all parts of the body, the number of immune cells will also decrease. At this time, the pathogen-immune balance maintained by the upper respiratory tract was broken, and the suppressed virus multiplied in large numbers, leading to our upper respiratory tract infection, which was manifested as a cold. ?

It must be pointed out that this regulation of blood flow does not only occur in winter. In summer, if you enter an air-conditioned room with low temperature from a very hot outdoor, your body can't adapt to the low temperature for a while, and a similar reaction will occur. ?

Of course, not only this situation will lead to the decline of human immunity, but also the loss of water in the body is a very common reason. ?

In summer, in order to dissipate heat and maintain body temperature, the human body will accelerate the evaporation of skin moisture. At this time, if there is not enough water, dehydration will occur. ?

In addition, the high temperature in summer often makes people lose their appetite, so they prefer a light diet. However, if the body can't get enough protein, it will also lead to decreased immunity. With the decline of immunity, the virus enters the room, causing people to catch a cold. ?

How to treat and prevent colds? ?

Seeing this, are you thinking that catching a cold and catching a cold in winter are the same thing, and I understand all the reasons, but in a sweaty summer, you can't always use "strengthening warmth" to deal with a cold like winter? ?

Of course, keeping warm in summer won't make you drink hot water wrapped in cotton-padded clothes like in winter, but when your body temperature is high, be careful not to covet coolness, don't blow air conditioners and don't eat cold drinks. ?

Another disadvantage of coveting coolness is that you won't feel water shortage in your body, and it is especially important to replenish water in summer. Only when there is enough water can the immune system fully play its role and regain the position taken away by the virus. Keeping warm, hydrating and resting are always the most effective ways to deal with colds. Cold medicine can relieve your symptoms, but it can't help you recover faster. ?

In addition, the common cold is often accompanied by bacterial infection. If the nose is yellow or has phlegm, it is a sign of bacterial infection. Therefore, when severe cold symptoms appear in summer, don't take it lightly because it won't "freeze" in summer, and don't think that everything will be fine after taking cold medicine and antibiotics. Be sure to see a doctor in time so that the doctor can judge the condition and prescribe the right medicine. If it is a virus combined with bacterial infection, antibiotics may be needed to eliminate bacteria; If it is only a simple virus infection, then antibiotics are not only useless to the condition, but also more likely to destroy the intestinal flora in the human body and be harmful to our health. ?

Heatstroke is different from a cold! ?

In addition to upper respiratory symptoms, colds may also cause fever, headache, dizziness and other systemic symptoms. ?

However, is a fever, headache and dizziness necessarily a cold? Considering the environmental factors in summer, there may be another disease that cannot be ignored behind similar symptoms, that is heatstroke. ?

In fact, there are many factors that can distinguish heatstroke from colds. ?

First of all, the reasons are different. Heatstroke is usually an acute symptom after continuous activity at high temperature, but the condition of a cold will gradually develop because it takes time for the virus to reproduce. ?

Secondly, there is a difference between the two symptoms. The symptoms of the upper respiratory tract are the characteristics of a cold, and heatstroke will not occur because there is no infection. According to the activities and symptoms before the onset, we can roughly judge what kind of disease is at work. ?

Of course, there will be two diseases at the same time. At this time, it is necessary to deal with the acute symptoms first, and make the patient recover from heatstroke through measures such as cooling and hydrating, and then slowly fight infection. ?

So much can be summed up in one sentence. ?

If you don't want to catch a cold in summer, you should do it: replenish water frequently, be nutritious, slow down your body temperature, and don't be greedy for cold. ?
