Blow your nose or do you prefer to raise it? Does washing your hands really make sense? Can vitamin C protect against infection? What experts advise.
As the seasons change and autumn and winter approach, colds become more common. However, viruses and bacteria can cause flu infections and symptoms all year round. With the cooler and drier air, these pathogens have an easier time entering the respiratory tract and causing infections. It is crucial to know how to protect ourselves against these infections and to be aware of certain tips and assumptions.
Once we catch a cold, flu-like infection, or viral infection such as influenza or COVID-19, it is essential to give our bodies plenty of rest by lying down and sleeping. Allowing our bodies to conserve energy and focus on recovery can speed up the healing process.
Many of us try various methods to prevent infection, but the reality is that there is no foolproof way to avoid getting sick. However, we can take certain precautions to reduce the risk of infection. There are numerous myths surrounding colds, and it’s important to separate fact from fiction.
One common misconception is that colds are always caused by bacteria. While bacteria can contribute to respiratory infections, viruses are the primary cause. There are different types of respiratory viruses, including rhinoviruses, respiratory syncytial virus (RSV), influenza virus, and SARS-CoV-2 (the virus that causes COVID-19). Viral infections can weaken the respiratory organs’ mucous membranes, making the body more susceptible to bacterial superinfections like sinusitis or pneumonia. To avoid this, it is crucial to take it easy and focus on curing the viral infection.
Another myth is that cold weather causes colds. While low temperatures can weaken the immune system, colds are primarily caused by viral infections like rhinoviruses that are active throughout the year. The outside temperature or cold itself is not the direct cause.
Proper hand hygiene is vital in preventing infections. Germs can easily spread through hand contact, and infection occurs when pathogens enter the body through the mouth, nose, or eyes. Regular handwashing can effectively break this chain of transmission and reduce the risk of infection. Washing hands is especially important after contact with germs. If handwashing is not possible, avoid touching the face or eating with unwashed hands. Carrying hand sanitizer can also be helpful.
Many people believe that taking extra vitamin C can protect against colds. While vitamin C can have benefits in promoting the healing process during a cold, it does not prevent infection. Studies show that intensive physical activity, such as in athletes or soldiers, can reduce susceptibility to infections by nearly half with vitamin C intake.
The act of blowing one’s nose versus pulling up mucus is often a topic of debate. Doctors actually recommend pulling up mucus as the tiny hairs in the nasal mucosa transport it towards the stomach. Stomach acid can then kill any germs present. This natural defense mechanism can prevent germs from settling and multiplying in the sinuses, thereby reducing the risk of infection. This advice is particularly relevant for individuals who have had sinus surgery.
It’s important to clarify the difference between flu and flu-like infections. Flu refers to an infection with the influenza virus, which can cause severe symptoms and complications. On the other hand, a flu-like infection refers to cold symptoms that resemble those of the flu, such as cough, fever, headache, and body aches. The pathogens causing these infections are often the same, such as rhinoviruses.
In conclusion, it’s essential to be well-informed about how to protect ourselves from infections. While there are many myths surrounding colds, experts provide valuable advice on hand hygiene, rest, and the proper care of respiratory infections.
