Health Matters...True or False?
It's amazing how many of these products prey on our belief in health and medical myths.
Here are a few interesting ones:
Drink at least eight glasses of water a day. It's true many of us don't get enough water, but there's no need to go crazy. We get plenty of water from eating fruits and drinking juice and coffee. If you drink too much water, you could actually get very ill from hyperhydration. I did a post on this topic last year on a radio contest that killed a woman trying to win a wii.
We only use a small percentage of our brains. I've heard we only use 3% of our brains. And then it became 10%. This is so absurd. If you've ever looked at an MRI scan of a brain in use can easily see that we use a whole lot of our brains. OK, maybe Jamie Lynn Spears uses 10% of hers.
Shaving hair makes it grow back thicker. My sister had very thin hair when she was a toddler. My parents decided to go ahead and shave her completely bald, thinking her hair would grow back much fuller and thicker. I'm sorry, sis, but that was not necessary. When you shave a hair, the new stubble grows without the finer taper at the ends of normal hair, giving the stubble the impression that it's thicker. (I was going to make a Brittney Spears joke here about shaving heads, but I think the Spears family deserves a little mercy).
Reading in dim light hurts your eyes. This is an old wives tale for sure. It might be a little tough to read under a dim light, but it doesn't do any damage. Also, crossing your eyes won't make them permanently stay crossed. This was just mom's way to make kids stop doing it. Staring at the sun, by the way, is true. Don't do it. Ever. Listen to your mother on that one.
Turn of your cell phone in hospitals. Having recently worked in hospitals, they have signs all over the place reminding you to do so. For some time, actually, this was not so necessary. But in the age of bluetooth technology, you do need to turn off the phone. Many medical devices work wirelessly these days as well, and modern cell phones CAN interfere with them. You probably won't kill a patient with a cell phone, but it's better to be safe than sorry.
Learn while sleeping. Many of us are taking on new challenges this year, which means taking college courses or expanding our horizons. The myth involves playing a recording of a lecture or information while you sleep so that it will somehow embed that information into your brain. So not true. HOWEVER, recent research has found that if you do need to learn some information quickly, review it right before you sleep. Most memory consolidation happens during sleep, so anything you read or examine right before you snooze is more likely to be placed in your long-term memory.
Here's to a happy and healthy 2008!
