As the respiratory virus season kicks off in the U.S., many are bracing for the inevitable bouts of colds that can hit hard and often. The reality is that adults typically catch two to three colds a year, leading to a chorus of coughs and sniffles during the season. While taking preventive measures, like washing your hands, is always wise, there are a plethora of myths surrounding colds that simply won't die. Infectious disease experts are here to clarify these common misconceptions once and for all.

Myth #1: There’s Only One Virus Responsible for Colds

One reason you might find yourself battling multiple colds in a single season is because they can be caused by over 200 different respiratory viruses. Dr. Thomas Russo, a leading infectious disease expert, explains that rhinoviruses are the main culprits in the U.S., but you're also at risk from various other viruses, including human coronaviruses and adenoviruses. It's important to note that while viruses like SARS-CoV-2, the flu, and RSV can mimic cold symptoms, they are not classified as cold viruses, according to the Centers for Disease Control and Prevention (CDC).

Myth #2: Wet Hair Increases Your Chances of Catching a Cold

The notion that going outside with wet hair can lead to catching a cold is a widespread belief. However, Dr. William Schaffner sets the record straight: "Colds are caused by viruses, and whether your hair is wet or you're feeling chilly doesn't influence that." Research has shown that exposure to cold, wet conditions does not impact cold infection rates. So leave that umbrella at home and enjoy a few raindrops!

Myth #3: Vitamin C Can Prevent Colds

Vitamin C has long been touted as a cold-fighting superhero, with shelves stocked full of supplements touting their protective benefits. But reality paints a different picture. Large-scale studies indicate that taking vitamin C regularly does not prevent colds; the National Institutes of Health (NIH) echoes this sentiment. Some research suggests that high doses of vitamin C can reduce the severity and duration of cold symptoms, but evidence for prevention remains weak. So, while it’s a good thing to have on hand, it may not be your first line of defense.

Myth #4: Colds Are Only a Winter Problem

While it's true that cold prevalence spikes during the colder months—September through May, according to the CDC—it's vital to recognize that colds can occur year-round. Viruses like rhinoviruses do affect people during the summer too, often attributed to enteroviruses, which thrive in warmer weather. So don't be surprised if you find yourself sniffling mid-July!

Myth #5: Antibiotics are Your Answer to Colds

With antibiotics frequently prescribed for various infections, it’s a common misconception that they can help clear up colds. But the truth is stark: antibiotics are effective against bacteria, not viruses. Prescribing them for a viral infection like a cold not only exposes patients to unnecessary side effects but also contributes to antibiotic resistance—a growing global health concern. If cold symptoms worsen, leading to severe issues like fever or persistent sore throat, seeing a healthcare provider for a proper assessment is vital.

In summary, staying informed about these myths can help you approach cold season with the right mindset—and the right remedies. Keep those hand-washing habits up, hydrate, rest, and consult with a medical professional if symptoms persist. Your health this season is worth it!
