6 Health Myths You Still Believe (Happy April Fools)

Happy April Fools. Except these aren't jokes. These are things millions of people still believe about their health, despite years of research saying otherwise. Consider this your annual myth audit.

Myth 1: You Need 8 Glasses of Water a Day

No single study has proven this number. The original recommendation came from a 1945 National Research Council report that included water from food in that total. It was never meant to be eight standalone glasses of plain water.

Your body has a built-in hydration sensor: thirst. Use it. Some people need more, some less. It depends on activity, climate, body size, and diet. Soup counts. So does fruit.

A naturopath may assess hydration markers as part of a fuller picture. Not by counting glasses.

Myth 2: Cracking Your Knuckles Causes Arthritis

Dr. Donald Unger cracked the knuckles on his left hand every day for 60 years. He never cracked his right. He published the results in Arthritis and Rheumatism in 1998. No difference between the two hands. None.

The sound is nitrogen gas bubbles collapsing in the synovial fluid. That is it. Satisfying? Debatable. Harmful? No.

You can relax. Or keep doing it to annoy people. Either is fine.

Myth 3: Detox Teas Cleanse Your Body

Your liver and kidneys are running a 24/7 detoxification operation. They do not need a $40 tea.

Most detox teas contain senna, which is a laxative. The weight you lose is water. The toxins you are flushing were already being processed by organs that have been doing this job since before tea existed.

If you want to support your liver, a naturopath checks actual liver markers, nutrient status (B vitamins, magnesium, glutathione precursors), and inflammatory load. That is what supporting detoxification actually looks like.

Myth 4: Cold Weather Gives You a Cold

Viruses cause colds. Not temperature.

The reason colds spike in winter is that people spend more time indoors, in close contact, sharing air. Cold air may also dry out nasal passages, which can reduce mucosal defense. But the temperature itself does not make you sick.

Researchers at the Common Cold Centre at Cardiff University confirmed this directly. You need a virus. You need exposure. The cold is just the backdrop.

Myth 5: Eating Late at Night Makes You Gain Weight

Total caloric intake and expenditure determine weight changes. Not timing.

A 2023 meta-analysis in the British Journal of Nutrition found no consistent evidence that meal timing independently causes weight gain when total calories are controlled. What matters: what you eat, how much, and your underlying metabolic health.

A naturopath checks fasting insulin, thyroid function, and cortisol patterns. Those are the actual drivers. The 10 PM snack is usually not the problem.

Myth 6: You Only Use 10% of Your Brain

Neuroimaging studies show that virtually all brain regions are active over a 24-hour period. Different tasks activate different areas, but there is no dormant 90% waiting to be unlocked.

This myth likely originated from a misquote of William James or early neuroscience that could not yet map brain activity. You use all of it. Some days it just does not feel like it.

The Real Myth

The biggest myth might be the one your blood work tells you: that everything is normal. Normal reference ranges are based on population averages, not optimal health. Half the population is average. That is not the goal.

A naturopath does not just check if you are within range. They check if you are where you should be. That is the difference between not sick and actually well.

60-minute consultations. Direct billing. No waitlist. Happy April Fools — but the care is real.
