In winter, the weather is cold, and all kinds of "folk remedies" for cold prevention and treatment have begun to attract everyone's attention. If you accidentally catch a cold, then the seven aunts and eight aunts, passers-by, A, B, C, D, will come out and ask you to use this little remedy, little secret recipe, and little trick to get well soon! But what about the reliability of these "small remedies"?
"Recipe One": Smoked vinegar can prevent colds
Conclusion: Not reliable
Boil a pot of vinegar at home to make the whole room full of acetic acid. I believe many people have this experience in preventing colds. However, experiments have found that smoking vinegar has no significant effect on the number of bacteria in the room, which means that smoking the room with vinegar does not sterilize and prevent colds.
On the contrary, if the concentration of acetic acid in the room is too high, it will burn the mucous membrane of the respiratory tract, and may even cause the onset or aggravation of patients with bronchitis, emphysema, and asthma.
"Remedy Two": Onions can "absorb" cold viruses
Conclusion: totally unreasonable
The saying "putting an onion in the room can effectively prevent colds" will spread in winter. The basis for this statement is that the cut onion can "adsorb" bacteria or viruses in the air. In fact, although onions are rich in organic sulfur compounds and have a certain antibacterial effect, it is unreliable to put onions in the room to absorb cold viruses by smell.
Experiments show that onions did not reduce the virus in the room. Therefore, putting onions at home will not help prevent colds.
"Three remedies": ginger soup helps treat colds
Conclusion: Suitable for people with cold and cold
In case of fever and headache, soups made with ginger, such as cola ginger soup and brown sugar ginger soup, have become "good medicine" for many people to treat colds. However, not all colds are suitable for treatment with ginger soup.
Ginger can sweat and relieve the surface and help dispel wind and cold. If you have a cold caused by wind and cold, drink a bowl of hot ginger soup, the patient will sweat slightly, which is indeed effective in treating colds. But if it is a cold caused by wind-heat, drinking ginger soup will backfire.
"Fourth Home Remedy": Covering sweat can cure a cold
Conclusion: Suitable for cold and cold
After catching a cold, cover it with a thick quilt, cover it with a sweat. This is a common way to deal with a cold. Like drinking ginger soup, this method is only suitable for wind-cold colds, because wind-cold colds are mainly treated by the method of pungent and warming to relieve the body, which will make the body sweat a lot more comfortable, but pay special attention to the limit of the whole body. , To prevent excessive sweating and loss of body fluid.
What needs special reminder is that after taking antipyretic drugs, excessive sweating is not conducive to heat dissipation, but will increase the body temperature in a short time, and may also cause dehydration.
"Five Remedies": Taking a cold bath can help prevent colds
Conclusion: only suitable for some people
"If you want to be healthy, take a cold shower every day." Many people feel refreshed after taking a cold shower. Even in winter, some people use cold showers to keep fit and reduce the chance of catching a cold. But in fact, the relationship between cold water bath and resistance is still at the stage of theoretical research.
For people with poor physique, taking a cold shower can not only eliminate fatigue, but also easily cause colds, fever and other illnesses, which should be avoided as much as possible. In addition, patients with coronary heart disease, acute hepatitis, hypertension, active rheumatism, and high fever should not take cold baths.
"Recipe Six": Eating oranges, effervescent tablets and supplementing vitamin C can prevent colds
Conclusion: There is no scientific evidence so far
The argument that vitamin C can prevent and treat colds has a long history, but studies have confirmed that vitamin C has little effect in preventing and curing colds. For ordinary people, taking vitamin C has no effect on the prevention and treatment of colds. It is completely unnecessary to take large amounts of vitamin C to prevent and treat colds.
"Recipe Seven": Banlangen can prevent colds
Conclusion: There is a certain effect, but not suitable for everyone
Seeing someone around you caught a cold, there were many people who took two bags of Isatis root to prevent it. In fact, Banlangen is not for everyone. Radix Isatidis is cold in nature and bitter in taste, and is more suitable for wind-heat cold caused by internal heat evil. People who are usually hot can also drink some for prevention during the cold season, but it is best not to exceed 3 days.
If the physique is partial to cold, it is not suitable to drink Banlangen. Especially for children, the function of the spleen and stomach is not yet fully developed. Taking too much isatis root is more likely to cause indigestion and other symptoms.
