When we meet again at work and school after the summer holidays, the number of colds skyrockets. The thing is that we are more indoors and in contact with people who are carriers of new viruses unknown to the body. But what is true and what is a myth when it comes to a disease that causes a runny nose?
1. Anyone can get a cold
Partly true. On average, an adult has a cold once or twice a year, but we all have different susceptibility to viruses.
“It looks like it is. It is noticeable that some catch colds more often and some rarely get sick,”confirms epidemiologist Anders Tegnell of the Public Health Organization.
Both the lifestyle and the number of contacts with other people are important. For example, women have colds more often, because they communicate better with young children. Immunity is also influenced by factors such as age, well-being, stress levels and fitness.
“The immune system is extremely complex and, moreover, its state is changing. Obviously, a lot is influencing her,”Anders Tegnell emphasizes.

2. Antibiotics treat colds
Not true. A recent study by the LIF and the Swedish Pharmacy Association showed that one in five Swedes is confident that antibiotics can cure the common cold. Ill, many go to the clinic. But antibiotics don't kill the virus. The best cure for a cold is rest, because then the body copes with the disease on its own. And symptoms can be treated in different ways.
3. Cold comes from cold, for example from the air conditioner in the car
Myth. Indeed, viruses survive better in cold and dark conditions, which is why we often catch colds in such conditions. But cold itself is not the cause of illness.
“Here are the factors that matter: firstly, we get into closer contact, and secondly, viruses survive better in cold environments,” says Andreas Tegnell.
What about an air conditioner in a car or plane, can you get sick from it, as many say? After all, the cold is still not the main culprit.
"This is probably due to the fact that the mucous membranes dry out from dry air and begin to retain viruses worse."
4. Whiskey and other folk remedies
Not true. A glass of whiskey, plenty of vitamin C, and fresh garlic are popular folk remedies for the common cold. Unfortunately, scientists say they are of no use. On the contrary, it is best to drink a lot - water or other drinks - to soften the course of the disease. Still, rest is the best treatment, and not a single folk remedy has been scientifically tested, Tegnell said.
5. Is it time to see the doctor?
Normally, the cold itself goes away, and the temperature drops after a few days. But if it doesn't get better, it doesn't hurt to go to the doctor, Vårdguiden emphasizes.
Sometimes a cold lasts longer, and if after a few weeks the patient does not recover, then it is possible that he is allergic. Symptoms of colds and allergies are very similar, but to find out if it is an allergy, you need to see a doctor. If one or two months have passed, then it's time.
