Cold refers to the infection of the nasopharynx through droplets or contact, which causes the nasopharynx to be infected. The symptoms include cough, redness, swollen and painful throat, runny nose, nasal congestion, fever, etc. Especially in winter, the temperature drops and it is easier to catch a cold due to cold.
Therefore, you will always hear the concern of "wear so little, be careful of a cold." But can you avoid a cold by wearing more clothes? In fact, this is a common myth! Without taking good warm measures, if you are exposed to cold air, you are prone to symptoms of nasal congestion and runny nose. Many people always think that this is a cold. Doctors say that simply runny nose is just a physical symptom. If a virus enters the nasopharynx, it will cause people to catch a cold
After the virus invades, the temperature regulation center of the brain will increase the body temperature, so it is easy to feel cold and even shivering. This is also the reason why colds are related to "cold".
On the other hand, when the temperature is low, the virus will be more contagious and survive for a long time, which will lead to colds being more likely to spread in low-temperature environments. Doctors remind that cold weather will not only increase the virus's contagiousness. If the amount of exercise is reduced, it will also lead to a decrease in resistance and make the virus prone to invading the body. It is recommended that you still pay attention to keeping warm and exercise appropriately during cold weather.
It must be fast to take medicine?
See a doctor as soon as possible when you have a cold, or go to the pharmacy to buy cold medicine, which is a way for many people to avoid aggravate the symptoms. Doctors say that most cold medicines are used to relieve symptoms, but they cannot shorten the time of cold.
The most important thing in fighting a cold is to rely on your own resistance. A balanced diet, more exercise, adequate sleep, etc. can all strengthen your resistance. During the cold epidemic, wearing a mask and washing hands more often are ways to protect yourself.
