As the cold of winter arrives and temperatures begin to dip, people around the world take measures to avoid catching a seasonal illness. However, it's essential to prioritize self-care at all times, regardless of the season. Unfortunately, misinformation often surrounds some of the most widespread public health concerns. For example, many individuals mistakenly believe that...
10. The FDA Approves Every New Chemical
Many people assume that before new or potentially harmful chemicals are introduced to the market, the FDA conducts at least some level of testing to ensure their safety. However, despite this being part of the FDA's role, the process doesn't always go as planned. For instance, triclosan, a key ingredient in many antibacterial products, was never properly reviewed by the FDA. This issue arose because many products were already in circulation before certain regulations mandated proper testing, leading to delays.
The delay with triclosan is nearly inexcusable, as the FDA has taken almost 40 years to make a decision on this contentious chemical, and they still haven’t reached a conclusion. While activists argue that it should simply be banned, the most absurd aspect is that the organization hasn’t provided an official stance yet. Apart from this example, there are many drugs that pass through the FDA with little to no research or testing to back up their claimed effectiveness.
9. Antibiotics Are Effective Against the Flu
While young people may not take illness seriously, parents of young children are often deeply concerned. This concern is understandable, but it can lead to overreactions that negatively affect society as a whole. Frequently, parents will take their sick child straight to the doctor, hoping for a prescription for antibiotics to quickly resolve the issue.
Unfortunately, there are many illnesses where antibiotics won’t be useful, and the flu is one of them. Using antibiotics when they aren't necessary can lead to antibiotic resistance, which is definitely a harmful outcome. Certain antibiotics are specifically designed to target bacteria and are not effective against most colds or flu-like illnesses, which are generally caused by viruses.
8. Antibacterial Soap Shields You From Germs
Many people now use antibacterial soaps regularly to ensure that germs don’t stand a chance. However, what they may not realize is that no matter how hard you try, germs will always be present on your hands, and this is actually by design. Antibacterial soaps eliminate everything—including the beneficial bacteria that naturally inhabit your skin.
It’s easy to think that if the harmful bacteria are taken down along with the good, it’s a win—but there’s no evidence to support that antibacterial soaps are actually providing any real benefits. Worse still, some experts believe that these soaps could be contributing to the rise of superbugs, which make it increasingly difficult for doctors to treat those who truly need antibiotics.
7. You Can’t Catch Chicken Pox Twice
One of the most prevalent myths surrounding diseases is the belief that once you’ve had chicken pox, you’re immune for life. Many parents have long believed that if a child contracts chicken pox in their youth, it will protect them from developing shingles later in life, as they can only get chicken pox once. Some parents even organize chicken pox parties so that all the kids in the neighborhood can catch it together. If your child misses the party, you might even receive an infected lollipop in the mail.
Unfortunately, this misconception could cause more harm than good. Chicken pox is actually known scientifically as herpes zoster, and as you may know, herpes tends to make repeat appearances. This means that those who had chicken pox as children can indeed get shingles as adults—and they may actually be more likely to. In the late 90s, a vaccine for chicken pox was developed that not only helps prevent chicken pox but also reduces the likelihood of shingles later in life. Sadly, it’s seldom used because many parents still believe it’s better for their child to contract chicken pox when they are young.
6. Hand Dryers Are Surprisingly Unhygienic
A common belief is that hand dryers are major contributors to the spread of germs. The argument suggests that they disperse germs everywhere and that the warm, humid air inside them creates the perfect environment for bacteria. Another concern is that when hand dryers are installed, paper towels are often removed, leading to more surfaces to touch with bare hands.
While there’s some truth to the idea that hand dryers can harbor bacteria under certain conditions, studies have found that using a hand dryer can actually increase the amount of bacteria on people’s hands. However, the good news is that these germs are generally harmless. The real problem, according to experts, is poor hand-washing practices (or not washing hands at all).
5. Face Masks Prevent Illnesses
During the peak of the swine flu outbreak, there were some bizarre misconceptions. For example, people believed that eating pork would give them the virus, while others took an extra precaution by wearing surgical masks everywhere they went. What’s a bit of social awkwardness if it means you’re protected from the season’s biggest pandemic?
Unfortunately, the bad news is that those masks aren’t designed to protect you from picking up germs while you’re out and about, and they won’t stop you from getting sick. But here’s the silver lining: they help contain your germs, preventing you from spreading illness to others. The proper use of a surgical mask is when you’re trying to keep your swine flu from infecting those around you.
4. Hydrogen Peroxide Cleans and Heals Wounds
Many people store hydrogen peroxide in their first aid kits to disinfect wounds, but it might be a good idea to swap it out for something else—or simply dispose of it. When you apply hydrogen peroxide to a cut, it bubbles and stings intensely, leading people to believe it’s having a meaningful effect. In reality, while it may be doing something, that something is not particularly beneficial for you.
Researchers set out to verify the common beliefs about hydrogen peroxide, and after conducting their experiments, they found that it’s likely ineffective at disinfecting cuts and scrapes. To make matters worse, remember the bubbling action we mentioned earlier? Well, it turns out hydrogen peroxide can actually harm skin cells, causing your wound to heal more slowly.
3. Mobile Phones Are Hazardous in Hospitals
In numerous hospitals, mobile phones and devices are prohibited in patient areas, and in some cases, they are completely banned. The rationale behind this is that phone signals can create electromagnetic disturbances that interfere with crucial hospital equipment. However, UK government officials have recently clarified that such an all-encompassing ban is unnecessary.
In reality, a variety of studies have been conducted to explore the potential interference between phones and medical equipment, and the findings aren’t nearly as concerning as initially thought. Studies that used realistic models revealed minimal interference, only occurring if the phone was placed directly next to the equipment. Moreover, there have been no confirmed fatalities attributed to mobile phone interference. While this doesn’t mean precautions shouldn’t be taken—since slight interference was observed at very close proximity—many health professionals still recommend keeping phones away from operating areas and vital equipment.
2. Multivitamins Are Beneficial for Your Health
In recent years, the diet trend has taken over the United States, particularly in response to the nation's rising obesity rates and other health concerns. While it’s a positive step that people are becoming more conscious of their health, sometimes the methods they use aren’t necessarily the best. Many Americans have adopted the habit of taking multivitamins or other supplements regularly, believing they are proactively improving their health, but the reality is that these actions may not provide any real benefit.
Numerous studies on multivitamins have concluded that they’re no more effective at preventing heart disease or cancer than a placebo. One study even found that some individuals who took multivitamins actually experienced a shorter lifespan. According to researchers, the issue is twofold. First, the supplement industry is poorly regulated, making it nearly impossible to verify whether a vitamin contains what it claims. Secondly, many doctors oppose the idea of healthy individuals taking multivitamins because if you're already getting sufficient nutrients, the additional vitamins could cause an excess of certain nutrients, leading to health complications.
1. You Shouldn’t Swim Immediately After Eating
One of the most widely accepted beliefs is that swimming right after eating can lead to serious cramps and even drowning. The recommended waiting period varies depending on which parent you ask, but the general warning is always the same. However, it turns out that this piece of advice is nothing more than a baseless myth.
To begin with, there has never been a confirmed case of someone drowning because they got a cramp from not waiting long enough after eating. More importantly, there’s strong evidence that the entire notion is completely absurd. There’s debate about whether it's even possible to get a stomach cramp in that way, and it's been pointed out that a mild cramp is hardly a life-threatening issue for a skilled swimmer. Worst case, you can always float—so it's certainly not something that will endanger your life.
