11 Of The Most Common Facts About Human Body That Turned Out To Be Wrong


Forget everything you ever heard from your grandparents about your body! Some of these facts we’ve gathered from Bright Side are so widely accepted that you’ll have a hard time believing otherwise. For instance, it’s not chocolate that causes blackheads on your face. But still, you may want to reduce your sugar intake as it causes several other problems in your body.

1. Vitamin pills keep us healthy


Actually, vitamins only regulate processes in our bodies, and we should be careful about taking them in tablet form since an excessive amount of them can do more harm than good.

2. Deoxygenated blood is blue in color


In fact, it’s still red (surprise surprise).They draw it blue in the textbooks to emphasize the contrast with oxygenated blood, and the veins you can see through your skin seem blue because the light shining on them gets refracted.

3. Brown sugar is healthier than white sugar


White and brown sugar are actually the same thing. They differ in terms of the use of molasses, which gives a product a darkish color. Brown sugar is often considered healthier because it’s not as sweet as white sugar, on account of the larger amount of water the former contains.

4. Alcohol kills brain cells


Excessive alcohol consumption can lead to a deficit of oxygen. This can harm the connections between brain cells, but it does nothing to the cells themselves.

5. Sugar makes children hyperactive

This is nothing more than a myth. Sugar means calories, and calories mean energy. So when children eat a lot of sweet things, the energy just flows out of them. But it’s harmful to their teeth. That’s still true.

6. Nerve cells don’t regenerate.

The death of nerve cells is a constant and entirely natural process. New ones appear in various different parts of the brain. When we feel stressed, it is the chemicals that make these cells function and interact with each other, rather than the actual nerve cells, which are used up.

7. The left hemisphere of the brain is the source of creativity; the right hemisphere is the source of logic.


It’s true that the two parts are responsible for different things. But scientists haven’t found anything that proves some people have one side that’s more developed than the other. In fact, several parts of the brain function as the collective source of our creativity, and they’re located in both the right and left hemispheres.

8. You need to get eight hours of sleep a night


Truth is, different people need different amounts of sleep. For some, it’s enough to sleep for six hours in order to feel great, while others feel exhausted even after they’ve been in bed for nine hours.

9. Antibiotics kill viruses


Antibiotics only kill bacteria. Influenza is caused by viruses that don’t react to antibiotics. In this case, it’s like applying a Band-Aid to get rid of a headache: it just won’t work.

10. Chocolate gives you blackheads


According to a recent experiment, chocolate has no effect on the number of blackheads on your face. Scientists gave dozens of people bars that contained ten times more chocolate than normal. When they compared the number of blackheads these people had before and after the experiment, they found no differences.

11. Sugar is addictive.


An experiment was conducted on laboratory mice in 2009. Scientists fed mice with large amounts of sugar over several days, and once they’d experienced this diet, they couldn’t live without sugar. When the experiment was repeated with human beings, however, the same effect did not occur.
