Can taking cold medicine before catching a cold really prevent a cold?

The common cold is caused by a variety of virus infections. As long as drugs against these viruses are found, colds can be cured quickly. Unfortunately, there is still no cure for colds. To some extent, it is terminally ill! Colds, also known as upper respiratory tract infections, are mainly caused by viruses. Overwork, climate change and colds will make us more vulnerable to viruses and produce various cold symptoms.

So far, no drug has been developed for cold virus in the world, in other words, no drug can make people recover from a cold as soon as they take it. Now all cold medicines are not used to treat colds, but to relieve all kinds of physical discomfort caused by colds. Common discomfort symptoms are: fever, cough, stuffy nose, sneezing, runny nose, sore throat and so on.

Therefore, although most drugs are written as cold medicines, it is embarrassing that they are not aimed at colds. And for the common cold, it is self-limited, and it can recover itself in 7- 14 days. So, Jenny, for the common cold, if you are unwell, you basically don't need to take medicine. Even if you really want to take medicine, it is best to choose a mild Chinese patent medicine to protect the liver, such as Baiyunshan Xiaochaihu granules, so as to avoid overdose and increase the burden on liver and kidney. So, since there is no specific medicine, how to treat a cold?

Due to some external reasons, direct inhalation of the virus, or decreased resistance due to colds or mental problems, make the virus more likely to invade the human body. When the body reacts, it will activate the immune system and fight the virus tenaciously. At this time, the most obvious reaction on the body surface is fever. Body heat can make the immune system more excited and inhibit the virus. Moreover, you need to consume a lot of energy and water when you have a fever. So you will be weak and need to drink more water. So, this is why the doctor will let you go home and have a good rest, because rest can make your body recover as soon as possible. The attitude of modern medicine towards colds is still based on rest+symptomatic treatment+prevention of secondary infection.

The general meaning is: lying down can be good! Colds are usually divided into common cold and influenza. We are familiar with the common cold, the most common is rhinovirus infection, but the flu is not necessarily. Influenza is a highly contagious disease, which spreads quickly. Under normal circumstances, the symptoms are general pain, sudden high fever, weakness and so on. You should pay attention at this time! The complications and deaths caused by influenza are very serious. ......
