Sugar pills, garlic chapters … there are many home remedies to deal with the general cold, but have scientific evidence that they work really?
There are not many experiences as well as suffering from cold. And although there are around 200 different factors that cause it, there seems to be almost as many home remedies for fighting.
But are none of these jobs?
Behind each home remedy the idea is that they help to strengthen the protection system.
When a virus comes into the body, it has two defensive systems: the defensive system that attempts to escape the aggressive cells and the changing system, which, focus on specific pathogens that the body had been talking and opposing. Creating protection by & # 39; Creating cells capable of fighting if they return.
- How the conditions affect your mental health
- Is a low diet in salt so dangerous to health as it will cost too much?
That is why we are likely to suffer from a seabird just once in life, although the sound is common – which changes appearance when we are in a position; going from one person to another, who opposed our cells – something we can know about many of our journeys
It is well established that their way of life and their diet affect the strength of our defense system.
But because our defense system is only limited when we have a deficiency or a mineral deficiency, we will make a little difference if we always have a good food, according to Charles Bangham, head of Department Infectious Diseases at the London Empire College.
"Only if there is a deficiency of essential nutrition, such as vitamin, sink or iron, it is very helpful to get further for that particular element, but if you have a balanced diet, more of those things will do for you. protective more efficient, "he says.
Despite this, there are some surveys that do; Ask about cures for common cold to find out that these can make a difference.
Most of this research is & # 39; Focusing on improvements, rather than food: in fact, a reliable investigation is not done at least how much cure-like cure is like a brot chicken. make a difference.
However, the development of which can help to be a popular home remedy: garlic.
In a small survey, 146 healthy adults received a venue or daily garlic recreation for 12 weeks during the winter.
The placement agency had 65 cold bodies that produced 366 days of sick leave, but those who gave the garlic apple had only 24 fuels, which were all 111 days of sick leave.
The other product has many people who have. turn when they show the cold signs to & # 39; including vitamin C. Some research suggests that it may also be useful, although not so large & nbsp; as possible.
Analysis of 29 inspections of vitamin C was not analyzed that these would significantly diminish the risk of a & # 39; suffer from cold or reduce their symptoms.
However, it found that there was a decrease in 14% cold in child case and 8% in adults. Researchers decided, because these are a low risk increase, it is worth trying to see them to help them.
Orange orange may not be as useful: there is no strong evidence that it helps to prevent cold, reduce or offset signals; reducing the time.
This is due to the fact that high vitamin C is not the same as everyday developments, according to Harri Hemilä, a healthcare researcher; public at Helsinki University and author of the survey of the reviews carried out on a low C.
A small bottle of orange juice made with a new zoo about 72 mg of vitamin C, according to the United States Department of Agriculture. That is bigger than the minimum daily measure that is recommended but much less than there are many improvements.
There's a sink there. An analysis of the effectiveness of daily zinc pills to deal with the common cold has been reduced by reducing the third time the patient's time was stopped or grunted, as well as being a & # 39; waste reduction and a 22% caste. half.
The survey concluded that if you were inserted within 24 hours after the first signal, a daily diez of 80 milligrams of sink can help you to; dealing with the cold.
However, Hemilä believes that it is more accurate to investigate a cold-free solution, rather than counting all the marks. His study of 199 patients found the common cold that the people who had a daily dose of sink grew three times faster.
Scientists often say that it is better to get vitamins and minerals through food, rather than to produce, although they often say it's much easier to get higher with improvements.
In a zinc case, however, it works better on the upside. To be effective in the face of the cold, sinks need to be cleaned in pills and not in rich logs or foods in this mineral, Hemilä notes.
"Ships are slowly spread in the area and have a sink effect locally. We do not know what biochemical is this, but surveys show pills when sink pills are effective, large heads that are spread up to 30 minutes in the mouth, "he says.
Often, researchers have found it difficult to investigate whether people had a deficiency in something like vitamin C or zinc before they started handling.
So, there may be no frustration against the cold because some of the participants have to disable the dampness instead of the # 39; make the development because the development would make a difference in healthy people.
Placebos's power is another problem. In fact, many surveys have a control group, such as the availability of garlic resources, which place a placebo, so we know that the effect is not only due to the effect of placebo.
But if we promise that there is nothing about it that there is no scientific or limited evidence, such as a cheese brot or orange juice, and # 39; cures us, maybe it is the result of a placebo impact.
Surveys have shown that placebos are an effective means of reducing many symptoms, from pain to irritation of irritable sheep, although the reasons for this are still not fully understood. And when it comes to vitamin C or chicken broth, the placebo place may help us to overcome the cold.
One study found that people who believed in the cold fighting features of his & her; echinacea stonestone that receives the disease as badly and for a short while while & # 39; as they were the daily dose of that plant than those who did not; believe there.
However, the previous partners did not know that they did not get a dose of that plant; Improvements in the cold symptoms.
He also works on the other side. For a long time, milk is suspected that mucus is made when we are cold, but it is proven to be deceitful. However, one study found that people who believed that milk is a mucus cause tell more of their respiratory problems.
Although placebos doctors usually have to be administered through clinical tests, placebo effects will affect home remedies from everyday life, notes of Felicity Bishop, professor of Health Psychology at Southampton University.
"Surveys show that the place-space's power comes from the relationship between patients and health professionals, someone who gives special attention and confidencefully remedies" he said. "And that's like what parents are doing when we are young, the kind of friendship is important, rather than that person."
Like the friends and the dependent family, the placebo situation can be reinforced by the way marketed food, according to the Bishop.
The good news is that you know that some residential remedies will not be surprisingly preventing them from going to & # 39; removing our marks.
"Even when a doctor tells patients that he has been a placebo in something but has helped some people, that can make sure that the person is more better, "he said.
Other comforts can be the comfort of those foods. Debtor Sarah Schenker says that the reluctance could be getting a chicken brot, for example, helping someone with a cold; feeling a little better.
In addition to the amount of C pollutants we use, the opportunity to & # 39; Get rid of winter cold rather than everyone, including what we do; Believe in placebos, but also according to our gene.
"The genetics of some people is particularly susceptible to particular diseases. It is much more important to be aware that we are different from each other: when some people have a cold, they do not even # 39 ; and it is realized, although others suffer from bad signs for the genes, which have a much greater impact. "
For most people with a healthy protection system, we can do much to do it; depends on the power of placebos to find out about winter viruses … However, some zinc or garlic provisions may also help.
