Don’t Believe Everything You Hear: 10 Health Myths Debunked

by Hemagirri Manisekaran

Everyone has its own set of health beliefs—some passed down from grandma, others write across social media. While a few may have grains of truth, many are myths that could lead to unnecessary worry or even harmful decisions.

Let’s shine a light on some of the most common health myths—and what science really says.

1. “You Must Drink 8 Glasses of Water a Day”

Not everyone needs exactly eight glasses. Your thirst is the best guide. Plus, foods like fruits and soups count toward hydration too. Listen to your body—it’s smarter than you think!

2. “Eggs Are Bad for Your Heart”

Eggs got a bad reputation for years, but research now shows that an egg a day is fine for most people. They’re packed with nutrients like protein and omega-3s, which are actually good for your heart.

3. “Antiperspirants Cause Breast Cancer”

This one’s been around for a while, but the National Cancer Institute says there’s no link between antiperspirants and breast cancer.

4. “Being Cold Gives You a Cold”

Colds come from viruses, not chilly weather. You might feel uncomfortable if you’re cold, but unless there’s a virus around, you won’t “catch” a cold just by being outside.

5. “You Need Detox Diets to Clean Your Body”

Fancy juices and expensive cleanses aren’t magic. Your body already has built-in detox machines: your liver and kidneys.

6. “Sugar Makes Kids Hyper”

Studies show sugar doesn’t make kids bounce off the walls. Often, it’s the expectation of hyperactivity that makes us notice normal energetic behavior more.

7. “Cracking Knuckles Causes Arthritis”

That popping sound? It’s just gas bubbles in your joints. There’s no solid link between knuckle cracking and joint damage.

8. “X-Rays Cause Cancer”

Yes, X-rays involve radiation, but the levels are very low. The benefits of diagnosing a problem early far outweigh the tiny risk—especially for one-off X-rays.

9. “Breakfast Is the Most Important Meal of the Day”

For some, breakfast boosts energy and focus. For others, skipping it doesn’t make a difference. The key is listening to your body and eating in a way that suits your lifestyle.

10. “The Five-Second Rule Keeps Food Safe”

The truth is, if food hits a dirty surface, it can be contaminated instantly. Better safe than sorry!

Knowing the difference between myth and medical fact helps you make smarter, safer choices. Don’t let old wives’ tales or online rumors guide your health. Instead, trust reliable sources, talk to healthcare professionals, and stay curious. After all, good health starts with good information
