1. Swallowing a Seed Won't Grow a Plant Inside You

You've probably heard that swallowing a seed might cause a watermelon or tree to grow in your stomach and harm you. While this sounds scary to kids, adults know it's impossible. However, this myth may have a practical origin: large fruit seeds like apricot or plum pits can get stuck in the esophagus, especially in children, causing blockage or injury.

2. Eating Lots of Sugar Won't Make Your Skin Stick Together

This is simply untrue. Carbohydrates are broken down in the intestines into glucose and absorbed into the bloodstream to fuel your body’s metabolism and energy needs. Sugar doesn’t cause your skin to stick or fuse.

3. Reading in Bed or in Dim Light Doesn't Ruin Your Eyesight

While proper reading posture involves sitting upright with good lighting, there is no solid evidence that reading lying down or in low light damages your vision. In fact, some studies suggest reading while lying on your back may slow the progression of nearsightedness.

4. Touching a Toad Won't Give You Warts

As children, many thought the bumps on a toad’s skin were warts that could transfer to humans. In reality, warts are caused by human papillomavirus (HPV) and are contagious only through direct human contact. The toad's bumps are glands that secrete substances to deter predators, effectively keeping people away.

5. Looking at Welding Sparks Can Harm Your Eyes

There is truth here: welders wear protective masks to shield their eyes from intense light. Watching welding sparks without protection can cause photokeratitis, a painful but temporary condition involving eye pain and light sensitivity. Fortunately, it’s treatable and reversible.

6. Crossing Your Eyes Won't Cause Permanent Strabismus

People often bring their eyes together towards the nose unconsciously throughout the day, a process called convergence that helps focus vision. Crossing your eyes won’t make them permanently crossed, and such exercises are sometimes recommended by eye specialists.

7. Eating Sunflower Seeds Won't Cause Appendicitis

Appendicitis is caused by blockage of the appendix, which can be triggered by hardened stool, swollen lymph nodes, mucus, tumors, or parasites. While foreign objects can cause blockage, eating sunflower seeds without shells generally poses no risk as they are digested normally.

8. A Needle Won't Travel Through Your Body to Your Heart

Though rare cases exist where needles inserted directly into veins migrated to the heart, these incidents typically involve intravenous drug use or medical errors. Needles stuck in soft tissue require medical removal, but the likelihood of a needle traveling through blood vessels to the heart is extremely low.

9. Not Wearing a Hat Won't Cause Meningitis

Meningitis is caused by bacteria, viruses, fungi, or parasites, transmitted mainly through respiratory droplets. Cold weather or exposure to wind doesn’t cause meningitis. Vaccination is the best prevention, though wearing a hat in cold weather helps avoid headaches and ear discomfort.

10. Swallowed Gum Doesn't Stay in Your Stomach for Years

Chewing gum isn’t digested but usually passes through the digestive system and exits naturally. Problems only arise if large amounts are swallowed along with constipation, potentially causing intestinal blockage, mostly in children.
