6 Old Wives' Tales You Likely Still Believe

Old wives' tales have been passed down through generations, often shaping our beliefs and behaviors. But as times change and science advances, many of these tales are being debunked. Here are six common myths you may still believe, explained with a dose of modern knowledge.

1. You'll Get Sick if You Go Outside With Wet Hair

It's a common warning from parents: "Don't go out with wet hair, you'll catch a cold!" However, according to Dr. Pritish Tosh from the Mayo Clinic, as reported by Business Insider, wet hair alone won't make us sick. But be warned, it could lead to hair damage, especially in cold weather. So, grab that umbrella, but don't worry about the sniffles.

2. Pull a Gray Hair and 2 More Will Grow Back

Pluck one gray hair, and two more will sprout in its place, right? Not quite. Dr. Shashank Kraleti with University of Arkansas for Medical Sciences explains that each follicle typically produces only one hair, so plucking won't cause a gray hair explosion, as reported by Business Insider. However, if your follicles stop producing melanin, more gray hairs may appear over time.

3. Sitting Too Close to the TV Causes Blindness

Parents often caution against sitting too close to the TV, fearing it'll damage children's eyesight. While intense screen time can cause eyestrain, it won't lead to blindness. The American Academy of Ophthalmology suggests taking breaks to prevent discomfort, but you can still enjoy your favorite shows without the fear of going blind.

4. Shaving Makes Hair Grow Back Thicker

Ever felt like your hair grows back thicker after shaving? It's a common misconception. Cutting or shaving hair doesn't change its texture or thickness. The illusion of thicker hair comes from the blunt edges of freshly cut hair. So, shave away without worry!

5. Gum Stays in Your Gut for 7 Years

Remember being told that swallowed gum would stay in your stomach for seven years? Turns out, it's just a myth. While gum isn't digested like other foods, it passes through your system like anything else you eat. So, if you accidentally swallow it, no need to panic — it'll pass through in time.

6. Swimming After Eating is Dangerous

The age-old rule of waiting an hour after eating before swimming is based on outdated beliefs. Contrary to popular belief, swimming shortly after a meal won't cause cramps or increase the risk of drowning. Your body diverts minimal blood from your muscles to aid digestion, posing no real danger while swimming.

As we debunk these old wives' tales, it's essential to rely on scientific evidence rather than superstition. While these myths may have once seemed plausible, understanding the facts can lead to healthier habits and peace of mind. So, the next time you hear one of these tales, you'll know the truth behind the myth.
