Recently, new crown has swept the country.
In the past, when I went out, acquaintances would always ask: Have you eaten? But now when greeting people, they always ask: Are there any sheep?
What I hear on the streets and online are people talking about cold symptoms after being infected with the new coronavirus, such as fever, headache, sore throat, cough, and runny nose!
Cold is a common thing in people's lives. From a newborn baby waiting to be fed to an elderly person, we have all experienced it!
Sometimes it’s a mild cold, sometimes it’s a severe cold. Most serious colds are influenza. Once you get a cold, everyone can deal with it calmly.
The most common pathogen of the common cold is rhinovirus. The most common pathogens of special colds are other viruses, including coronavirus, parainfluenza virus, respiratory syncytial virus, etc. After viral infection, it will cause cell pathology and inflammatory reaction. The released inflammatory mediators will increase the permeability of blood vessels, causing the plasma to penetrate into the nasal mucosa, increase the secretion of nasal glands, and cause respiratory symptoms such as runny nose and nasal congestion, as well as systemic symptoms such as fever and body pain. Symptoms often appear within 16 hours after the virus infects the body, reach their peak within 24 to 48 hours, and reach the peak of virus shedding within 2 to 3 days.
Whether it is a common cold or influenza, most of them can eventually recover on their own. This is due to our body's sound immune function.
During a cold, the main symptoms include runny nose, nasal congestion, fever, sore throat, cough, etc. These symptoms can cause varying degrees of discomfort, and generally symptomatic treatment is sufficient.
However, if these symptoms worsen to a certain extent, they will seriously affect daily life and work.
Today we will talk about fever caused by colds. It refers to the fact that after the virus invades, the body's immune system starts to fight, and heat production increases, but the heat dissipation cannot increase accordingly, or the heat dissipation decreases, causing the body temperature to rise beyond the normal body temperature range, resulting in fever.
Fever may burn out the brain and affect IQ. It may burn out the body, causing damage to various organs and leaving sequelae.
The human body feels comfortable within the normal temperature range. If low or medium fever occurs, most people will feel a little uncomfortable. If the fever is 39℃ or above, most people will have headache symptoms. If 40℃ and above, that is the temperature ceiling of the human body. Imagine that the water released from the hot water faucet in our homes is usually within 40℃. If it exceeds 40℃, it is a bit hot, and our hands will instinctively retract after touching it.
Therefore, if the body is exposed to temperatures of 40℃ and above, and it is unavoidable, then the body can still withstand it for a short period of time, and it lasts for a long time. The fragile parts of the body such as the brain, liver, kidneys and other internal organs are like eggs, proteins are denatured and coagulated when exposed to high heat. It can cause body dysfunction, eventually leading to convulsions, coma and even death. Even after rescue, sequelae may remain.
Therefore, high fever is the warning line for human life. No matter what the cause of high fever is, it must be cooled down to help the body survive the disaster.
Therefore, body temperature monitoring is indispensable whether it is treatment in the hospital or observation at home. Because the normal temperature of the human body is really one of the key vital signs.
The range of normal body temperature is: oral cavity: 36.3℃～37.2℃;
rectum: 36.5℃～37.7℃;
armpit: 36.0℃～3 7.0℃,
fever refers to oral temperature ≥37.3℃, axillary temperature ≥37.1℃, rectal temperature ≥37.8℃
low fever refers to oral temperature is 37.3℃-37.9,
moderate fever refers to oral temperature 38.0-38.9℃,
high fever refers to Oral temperature ≥39℃
Hypothermia refers to temperature lower than 35.0℃
Most patients with high fever will experience headache, chills and other discomforts, which require timely symptomatic treatment. Mild and moderate colds generally require no special treatment, but some people are intolerant, and symptoms that significantly affect work and life need to be treated in time.
processing is mainly cooling: physical cooling and drug cooling .
physical cooling
body temperature is 39 degrees, generally physical cooling is enough. The so-called physical cooling is to use physical principles such as convection, conduction, evaporation, etc. to remove heat from the body.
For example, open windows for ventilation and loosen or reduce clothes to increase air flow and take away heat.
If you drink more soup, it can promote metabolism in the body, increase urine output, urinate to relieve heat, and also make the body sweat to dissipate heat to achieve the purpose of cooling down.
For example, if you have a cold compress, when you have a headache accompanied by obvious fever symptoms, use an ice pack or ice pillow to apply cold compress to the head, which can quickly cool down the head.
For example, use warm water for a sponge bath or use 75% alcohol to rub elbows, armpits and other parts to achieve a rapid cooling effect.
Medications for cooling
If the body temperature is ≥39°C, if physical cooling is ineffective, requires medication for cooling, and you need to see a doctor for specific medication.
Precautions after fever:
After the virus invades, the immune system needs to mobilize the whole body to deal with the virus, which will suppress digestion, exercise and other systems to save physical energy, so people will feel tired, sleepy, and lose appetite. Therefore, don’t make trouble for your body at this time, and don’t be stubborn. After a cold, you must combine work and rest, follow a regular work and rest schedule, and get more rest.
After the virus invades, the operation of the immune system requires a large amount of water to assist, so drinking more soup and urinating can promote metabolism and eliminate toxins and garbage in the body.
After the virus invades, maintain a good attitude, avoid further disorder of the immune system function caused by mental anxiety and tension, and protect the immune system's disease resistance;
After the virus invades, the diet should be regular, small and frequent, and the food should be diversified. Eat more fresh vegetables, fruits, soybeans, milk, etc., which are light but not greasy, and avoid spicy and irritating foods. This can supply the fighting energy of the immune system.
Secondly, after
catching a cold ( flu, new coronavirus ), you should not lower your self-protection standards because of "yangkang". When going out, you must wear a mask scientifically to reduce gatherings, and avoid going to crowded and closed places unless necessary to avoid being harmed again.
