Cold Weather & Illness: Debunking the Myth of “Catching a Cold”

Despite persistent beliefs, simply being cold does not directly cause illness. new insights from medical professionals are challenging long-held assumptions about wintertime sickness, emphasizing the role of viruses and bacteria rather than temperature itself.

For generations, parents and grandparents have warned children to “put on your coat, or you’ll catch a cold.” This ingrained advice, however, is increasingly being questioned by experts. A recent video featuring media doctor Jimmy Mohamed, presenter of France 5’s “Health Magazine” on RTL, garnered over a million views in recent days after he stated, “A child who does not cover up is not going to get sick. We stupidly repeat what our parents told us. But a child who goes out in shorts and a t-shirt, even when it is cold, is not likely to get sick.”

The Reality of Winter Illness

according to Dr. Chevallier, a general practitioner in Paris, the cold itself is not the culprit. “You can go out lightly covered or with wet hair, even with negative temperatures you will not get sick,” she explained to CNews. The true cause of illness lies in exposure to viruses or bacteria that infect the mouth or nose.

The increased incidence of illness during winter isn’t due to the cold causing sickness, but rather to the conditions that allow viruses and microbes to thrive. These pathogens circulate more readily in colder months, and, crucially, they prefer the cold. Moreover, winter frequently enough leads to increased indoor time with less ventilation, creating an environment where transmission is easier.This close proximity facilitates the spread of infectious agents between people.

Did you know?– Viruses and bacteria, not cold temperatures, are the primary cause of winter illnesses like the common cold and flu. Increased indoor crowding and lower ventilation during winter months contribute to their spread.

Protecting Yourself During Cold Weather

While venturing out in shorts and a t-shirt isn’t advisable, understanding the true source of illness allows for more effective preventative measures. Prioritizing hygiene and adhering to barrier gestures remain paramount.This includes:

• Washing hands thoroughly before eating and after using the restroom.
• Sneezing into your elbow.
• Wearing a mask in crowded indoor spaces.
• staying home when feeling unwell.

Pro tip:– Frequent handwashing with soap and water is one of the most effective ways to prevent the spread of viruses and bacteria. Focus on washing for at least 20 seconds.

Its significant to note that while the cold doesn’t directly cause illness, it can subtly weaken immune defenses and increase the risk of hypothermia, particularly in young children. The body also expends more energy maintaining its core temperature in cold conditions.

Heart Health & Cold Temperatures

The cold poses a particular risk to individuals with pre-existing heart conditions. As temperatures drop, blood vessels constrict, blood thickens, and blood pressure rises, placing additional strain on the cardiovascular system. A 2019 study published in the British medical Journal found that a 1°C decrease in outdoor temperature correlated with a 2% increase in the risk of myocardial infarction within the following four weeks. Symptoms to watch for include:

• Tightness in the chest
• Shortness of breath
• Chest pain during exertion
• Palpitations
• Dizziness

Reader question:– Can cold weather worsen existing heart conditions? Yes, cold temperatures can increase blood pressure and strain the cardiovascular system, raising the risk of heart attack.

Understanding the true causes of winter illness empowers individuals to take proactive steps to protect their health, moving beyond outdated beliefs and embracing evidence-based preventative
