For as long as we’ve had bodies and minds capable of thinking about these bodies…we’ve thought wrong things. Obviously, we’re always learning and improving, but some misconceptions persist. Perhaps it’s time to do away with a few of these.
Let’s jump right in with one of the most common…
You should drink 8 glasses of water per day.
Actually, you consume most of the water your body every day needs through food—so don’t force yourself to drink more water if you’re not thirsty. Remember: you can drink too much water.
You can “sweat out” toxins.
Sweat glands are in your skin, and since they’re not connected to any other bodily systems, they can’t eliminate “toxins.” And besides, sweat is your body’s way of cooling itself down—it’s made up of water, salt, and electrolytes. That’s it.
Vaccines give you the virus they protect you from.
Actually, while vaccinations do include parts of a virus, they’re not enough to make you sick. Instead, they work by stimulating your body to create antibodies, so that if you ever do come into contact with it, your body will already be equipped to fight it off.

Sugar makes kids HYPER.
Studies have found that this simply isn’t true. It’s more like a self-fulfilling prophecy. Kids are already hyper. Giving them sugar isn’t going to make that any worse.

Hair and fingernails are alive, and keep growing…even after you’re dead.
We’ve all heard this super creepy rumor, right? Well, fortunately, it isn’t true. Unfortunately, the reasoning is still creepy and gross: after death, the skin dehydrates and retracts, making it look as though hair and nails are still growing. Sweet dreams!
