8 Health Myths You Probably Believe

Posted in General Health 11 Jun, 2015

A whole host of health-related myths have infiltrated the brains of those paying more attention to Facebook than science lessons. Let's have a good clear out, shall we?

1. Eating powdered rhino horn will give you an erection

Eating the body part of an endangered species will not enhance your sex life. There is no proof that tiger claws, rhino horn or gorilla penis will do anything for sexual prowess. The only aspect that might help out is the placebo effect, and frankly that could be done with a few Smarties.

2. Teeth should be bright white

Yes, bright white teeth look nice, but human teeth are not naturally snow-white, they are yellow. Scrubbing your teeth with mostly useless whitening toothpastes won't help much, they won't change the basic colour of your teeth. Professional bleaching will, but might weaken the enamel.

3. We only use 10% of our brain

Just because you're not solving a maths probability puzzle about algebra and sweets it doesn't mean your grey matter is snoozing. No medical evidence exists to show we don't use all of our brain. That's why brain damage is so devastating.

4. Sugar makes children hyperactive

Ice cream, jelly, Haribo and Sunny Delight (now I'm hungry) all contain sugar in vast quantities. Sugar is bad for you, but there's no evidence it makes children hyperactive. They don't need any stimulant to act like furious mini-warlords, they have all-natural hyperactivity because they don't work all day to pay a massive mortgage.

5. Cracking your knuckles gives you arthritis

Nope. It's not your bones cracking, it's the gas formed when your joints stretch and the synovial fluid moves about in the gaps. No medical connection has ever been made between cracking your joints and developing arthritis. A man called Unger received a Nobel prize in 2009 for figuring that out.

6. The Moon Affects Periods

The theory is that because the human body is mostly water, the moon's gravitational pull affects women much like it pulls tides back and forth, but there's no evidence to prove it.

Women have always been associated with the moon. Who'd have thought a piece of rock orbiting our plant could be the cause of PMS, spots and the desire to kill? Sounds ridiculous and that's because it is. Unless you are a Lycanthrope.

7. Shaving hair makes it grow back thicker

Those warnings from your granny about removing facial hair have no basis in scientific fact. Hair may look darker when stubble grows, but that's because it hasn't been bleached by the sun yet. Hair on your body is dead; the living portion is under your skin. Removing it doesn't affect the living part.

8. You can catch a cold from the rain

No, you can't develop a cold from forgetting your umbrella. You will be wet, angry, embarrassed and your clothes may become see-through, but you won't catch germs from it. Colds are either viral or bacterial infections.

Some research suggests that being cold activates cold germs though, but that's a whole different blog post.
