14 Widely Believed Myths Busted by Scientific Evidence

14 Widely Believed Myths Busted by Scientific Evidence

Sharing is caring!

We’ve all heard them—those widely accepted “facts” that seem too strange or interesting to be anything other than true. From old wives’ tales to urban legends, misconceptions have had a way of sneaking themselves into our collective consciousness for a long time. But, as science progresses, many of these steadfast beliefs are exposed as nothing more than myths.

It’s intriguing how easily misinformation can spread, taking on a life of its own and becoming accepted as truth. But the beauty of science lies in its ability to challenge assumptions and illuminate the reality behind these captivating tales.

In this article, we are debunking 14 common myths with the unquestionable power of scientific evidence. Prepare to have your long-held beliefs challenged and your understanding of the world enriched.

1. Goldfish Don’t Have A 3-Second Memory

Goldfish possess a memory span far exceeding the 3-second claim. Research indicates they can retain information for several months. They can remember their owners, distinguish between colors, and even be trained to perform simple tasks.

The myth of their short memory likely arose from their tendency to swim in circles, seemingly forgetting their destination. However, this behavior is more likely due to their limited spatial awareness rather than a lack of memory capacity.

2. Camels Don’t Store Water In Their Humps

Camel humps are reservoirs of fat, not water. This fat serves as an energy source when food is scarce, enabling camels to endure long periods in arid desert environments where sustenance is limited.

The myth of water-filled humps likely stems from the camel’s remarkable ability to survive for extended periods without drinking. While they can go for days without water, their humps do not store it. Their survival is attributed to other adaptations like efficient water conservation mechanisms and the ability to tolerate significant dehydration.

3. Shaving Doesn’t Make Hair Grow Back Thicker

Shaving does not alter the thickness or growth rate of hair. When hair regrows, the blunt tip might feel coarser, creating the illusion of thicker hair, but this is merely an illusion.

The hair’s structure and growth cycle are determined by factors beneath the skin’s surface, which is unaffected by shaving. The blunt tip of regrown hair can feel rough compared to the tapered end of unshaven hair, but its actual thickness remains the same.

4. You Shouldn’t Necessarily Drink 8 Glasses Of Water A Day

While staying hydrated is essential, the “8 glasses a day” rule is not a one-size-fits-all recommendation. The amount of water you need depends on various factors, including your activity level, climate, and overall health.

Listen to your body’s signals and drink when you’re thirsty. Water-rich foods and other beverages also contribute to hydration. However, it’s important to avoid overhydration, which can be harmful.

5. You Don’t Lose Most Of Your Body Heat Through Your Head

The idea that you lose most of your body heat through your head is a misconception. You lose heat proportionally from any exposed part of your body. While your head is often uncovered, leading to greater heat loss in cold weather, it’s not a disproportionate amount compared to other exposed areas.

This myth might have originated from studies conducted on infants who have a larger head-to-body ratio. However, for adults, heat loss is evenly distributed across exposed skin surfaces.

6. Vaccines Don’t Cause Autism

Numerous scientific studies have thoroughly debunked the claim that vaccines cause autism. The original research that sparked this myth was retracted due to fraudulent data and unethical practices.

Vaccines are safe and effective in preventing infectious diseases. They are rigorously tested and monitored for safety, and the benefits of vaccination far outweigh any potential risks.

7. You Don’t Swallow Eight Spiders A Year While Sleeping

The idea that we unknowingly swallow a significant number of spiders while sleeping is a persistent urban legend. Spiders are generally not attracted to sleeping humans and are unlikely to crawl into our mouths.

While it’s possible that a stray spider might wander into your bed, the chances of you swallowing one while asleep are incredibly slim. Rest easy knowing that your nighttime slumber is not a spider buffet.

8. “Hair Of The Dog” Doesn’t Cure A Hangover

The “hair of the dog” approach, which involves consuming more alcohol to alleviate a hangover, is not a scientifically supported cure. In fact, it can prolong your recovery and worsen your symptoms.

The best way to deal with a hangover is to rehydrate, rest, and allow your body to process the alcohol in its own time. Time is the only true cure for a hangover.

9. Eating Before Swimming Doesn’t Cause Cramps

There’s no scientific evidence to support the claim that eating before swimming increases your risk of cramps. While it’s wise to avoid heavy meals before strenuous activity, a snack won’t put you at risk of cramping in the water.

Factors like dehydration, muscle fatigue, or electrolyte imbalances are more likely to cause cramps. Staying hydrated and properly warming up before swimming are better strategies for preventing cramps.

10. The Coriolis Effect Doesn’t Determine the Direction Water Draining

The Coriolis effect, which influences large-scale weather patterns, is too weak to affect the direction of water draining in a toilet. The direction of the swirl is primarily determined by the shape of the bowl and the initial movement of the water.

While the Coriolis effect plays a role in the rotation of hurricanes and other large-scale phenomena, its influence on small-scale events like toilet flushes is negligible.

11. Humans Don’t Get Warts From Touching Toads

Toads do not cause warts. Warts are caused by the human papillomavirus (HPV), which is spread through direct contact with infected skin.

The bumpy texture of a toad’s skin might have contributed to this myth, but there’s no scientific basis for the belief that touching a toad will give you warts.

12. A Penny Dropped From A Skyscraper Can’t Kill Someone

While a penny dropped from a great height can gain significant speed, it’s unlikely to kill someone. Its flat shape and low weight create air resistance, limiting its terminal velocity.

While it’s certainly not advisable to drop objects from tall buildings, the impact of a penny, even from a skyscraper, is more likely to cause a bruise than a fatality.

13. Eating Spicy Food Doesn’t Cause Ulcers

Spicy food doesn’t cause ulcers. Ulcers are primarily caused by bacterial or viral infections or the long-term use of certain medications.

While spicy food can irritate existing ulcers or cause discomfort in individuals with sensitive stomachs, it doesn’t directly cause them. In fact, some studies suggest that certain compounds in spicy foods might even have protective effects on the digestive system.

14. It’s Okay To Drink Milk When You Have A Cold

Drinking milk when you have a cold doesn’t worsen congestion or increase mucus production. This myth likely stems from the temporary thickening of saliva that can occur after consuming dairy products, which might be misinterpreted as increased mucus.

Milk is a nutritious beverage that can provide essential vitamins and minerals when you’re feeling under the weather. It’s safe to consume even when you have a cold.
