There are some things that we believe in only because others believe in them. As a rule, we don’t think about whether something is true or not. We bet you think milk is useful for your bones and that Mount Everest is the highest mountain in the world. If you still believe those things, it’s time to learn the truth.
Bright Side wants to debunk a few myths that the majority of people still think are true.
9. The placebo effect works for humans only.
In fact, the placebo effect might work for your pet too. For example, if a dog is sick and its owner gives it a pill, the dog reacts. The owner can give it a pill and the dog will stop feeling pain (even if it’s just a vitamin pill).
8. Milk is useful for our bones.
Ads claim that dairy products are a great source of calcium which is really important for our bones. But calcium contained in milk doesn’t prevent us from getting fractures. Scientists from Harvard University have found that people from countries that don’t usually consume dairy products suffer from fractures less than those who consume such products regularly. So there’s no sense in drinking big amounts of milk if you want to strengthen your bones. You can get calcium from sardines and salmon, beans, almonds, and figs.
7. Chocolate causes acne.
Many people don’t eat chocolate because they’re afraid it’ll affect their skin. But it’s not true. Researchers conducted a study and gave subjects bars containing 10% of the amount of chocolate in a typical bar. The study showed that chocolate wasn’t harmful to our skin and didn’t affect it at all. Dermatologists confirmed that the results were accurate. So if you don’t have any contraindications, chocolate won’t affect your skin.
6. If you run, you have to run every day.
Scientists have conducted research and found that everyday running can harm our health and become completely useless for those who want to be healthy and fit. Running too much may lead to heart disease, high blood pressure, Alzheimer’s Disease, and premature aging. If you like to run, it’s recommended to run at speeds around 5 mph. Overall, it’s better to run 3-4 times a week with a total distance of 19 miles.
5. A black hole is actually a hole.
Some people think that black holes are holes. In fact, these are just space objects where gravity pulls so much that even light can’t get out. Only telescopes can find a black hole and help people see how stars that are close to black holes act differently than other stars.
4. Mars is red.
Many people think that Mars is the red planet. In the 1970s Nasa’s Viking 1 lander became the first spacecraft to touch down on the planet and took several photos. Initial images revealed that there was a blue sky, not a pink one. NASA probably just wanted the planet to look more hostile. Today, NASA admits that some parts of Mars are actually blue and grey.
3. Mount Everest is the highest mountain in the world.
Undoubtedly, many people think that Mount Everest is the highest mountain. It’s called that because it has the highest elevation above sea level. If we consider the total height of mountains, Everest isn’t the highest summit. Mauna Kea, a volcano located in Hawaii, has an altitude of 13,796 ft and its base is about 19,039 ft below sea level.
2. You’re safe inside a car during a lightning storm since it has rubber tires.
There’s a belief that during a lightning storm, you’re safe inside a car due to its rubber tires. But it’s just a myth. Your car may be a really good place to hide but only because it’s made from metal. This kind of protection will work only if all the doors and windows are closed.
1. The Sahara is the largest desert in the world.
If you ask a person which desert is the largest, they’ll probably answer, “The Sahara!” If they say this, they’ll actually be making a mistake. When we think about a desert, we usually imagine a lifeless, extremely hot area with incredible amounts of sand. But a desert is a landscape that receives very little precipitation. In this case, Antarctica is the largest desert in the world.
