In everyday life, health myths and folk remedies often spread quickly. Many people unknowingly fall for so-called “wellness secrets,” thinking they’re doing something good for their bodies. However, these practices are often unscientific and may even pose serious health risks. Here are 12 common health misconceptions to watch out for:

1. Eating raw fish gallbladders can cure illness?

Some believe consuming raw fish gallbladders can detox the body, improve eyesight, or treat diseases. In reality, this is extremely dangerous. Fish gallbladders can contain toxic substances like sodium cyprinol sulfate, histamines, and hydrogen cyanide, which can damage the liver and kidneys and, in severe cases, lead to multiple organ failure. Instead of healing, it could be life-threatening.

2. People with gallstones should go vegetarian?

Many gallstone sufferers think eating only plant-based foods can prevent their condition from worsening. But a long-term vegetarian diet may lead to deficiencies in fat-soluble vitamins and animal proteins, potentially causing anemia or low protein levels. Moderate fat intake actually helps stimulate bile flow and prevent bile buildup.

3. Is holding your breath for 30 seconds really an accurate way to assess your lung health?

This common trick does not accurately measure lung function. Lung health depends on many factors, and holding your breath is not a reliable diagnostic tool. If you're experiencing respiratory symptoms, consult a doctor for a proper pulmonary function test.

4. A vegetarian diet helps lower blood lipids?

While plant-based diets can support weight loss, eating only vegetables doesn't guarantee healthy cholesterol levels. Lacking B vitamins, some vegetarian diets may disrupt fat metabolism and actually raise lipid levels. The key is moderation: eat more vegetables while still including some lean animal protein.

5. Does plucking a single white hair really lead to the growth of ten more?

There’s no scientific basis for this. The number of hair follicles is fixed at birth—plucking white hairs won’t create more. However, regularly pulling out hairs can harm the follicles, which may cause irritation or even long-term hair loss. It’s best to leave white hairs alone or manage them gently.

6. Prostatitis only affects older men?

Many think prostatitis is an “old man’s disease,” but it’s also common among younger men, particularly those with frequent sexual activity. Repeated sexual arousal can lead to prostate congestion and inflammation. Good hygiene and a strong immune system help reduce the risk.

7. Lung nodules will definitely turn into cancer?

Hearing the term “lung nodule” often causes panic, but most are benign—especially small or tiny ones. They often cause no symptoms. With regular checkups and medical guidance, most cases require monitoring, not panic.

8. IV drips in fall and winter can prevent strokes?

Some older adults receive intravenous “blood-activating” drugs in cold seasons, thinking it prevents stroke. In truth, IV therapy doesn’t offer stroke prevention and may even cause side effects. The best prevention includes healthy habits: monitor blood pressure, cholesterol, and blood sugar, eat well, and stay active.

9. Bone broth helps bones heal after a fracture?

Despite popular belief, bone broth isn’t especially helpful for healing fractures. It’s rich in fat, not calcium. Proper bone healing depends on getting enough calcium and vitamin D.

10. Frequent vaginal washing is healthier?

Many think daily washing of the vagina prevents infections. However,Excessive washing can upset the vagina’s natural acidity, making it more prone to infections.Gentle rinsing of the external area with clean water is sufficient—avoid harsh soaps or cleansers.

11. Kidney patients should switch to low-sodium salt?

Kidney disease patients must control sodium intake, but low-sodium salt isn’t always safer. It often contains more potassium, which can lead to dangerous potassium buildup. The safest approach is simply reducing overall salt intake—not relying on substitutes.

12. General anesthesia affects brain function?

There’s no scientific proof that general anesthesia causes lasting cognitive damage. Modern anesthesia is safe, with drugs that are quickly metabolized and eliminated. With today's advanced techniques, adverse effects are minimal, and patients can feel confident going into surgery.
