Low temperatures cause colds, and it’s best to sweat out a fever – or perhaps not? There are numerous myths surrounding the common cold. But what are the facts?
A runny nose, sore throat and headache are the typical symptoms of the common cold that many people are familiar with. These complaints are most common during the colder months of the year, and there are many misconceptions regarding colds that do the rounds.
Myth 1: Colds are caused by low temperatures
False. Although colds occur more frequently in the winter, the low temperatures alone are not what causes them. The immune system has to work even harder to cope with the constant switching between the cold air outside and the heated air inside. Dry, heated air can also dehydrate our mucous membranes, weakening our natural protection against viruses and bacteria. So the low temperatures only have an indirect effect.
Myth 2: A cold can develop into flu
False. The symptoms of the common cold and flu are similar, which is why a cold is also referred to as a flu-like infection. But the two illnesses are caused by different viruses. A cold can only turn into flu if an already weakened immune system is then also attacked by the flu virus.
Myth 3: A flu vaccine also provides protection against colds
False. Because flu and colds are caused by different viruses, the flu vaccine does not provide any protection against colds. But it is still worth getting the flu vaccine, because flu is usually more severe than a cold.
Myth 4: Stress can make you ill
True. Persistent stress causes the body to release more stress hormones such as cortisol. These weaken the immune system and make you more susceptible to infectious diseases. That’s why relaxing and getting enough rest are important for staying healthy.
Myth 5: You should sweat out a fever
False. If you have a cold, your body is already weakened, and fever puts an additional strain on it. Most people get cold when they have a fever, and should try to keep warm. But you shouldn’t wrap up too much, because an increase in temperature stresses the body even more.
Myth 6: Tilting your head back is better than blowing your nose
True. Blowing your nose creates high pressure in the throat, which can cause pathogens to enter the sinuses and trigger inflammation there. This can prolong the duration of your illness. That’s why it’s better to carefully tilt your head back when your nose is running.
