Top 10 False Health Myths Debunked by Science

In our lifestyle, many things are changing, and we are always adapting to new methods. Our life has changed drastically because of science, and the importance is something we cannot deny. Science is critical to our human evolution – both mental and physical. However, not all things related to science are correct. Science is more theory than actuality. Here, we take a look at top 10 things that science got totally wrong.

1: Red makes Bulls Angry

Anyone who is familiar with bull fighting would know that when a bull sees a red cape with the matador, it gets angry and really aggressive. Most of us have grown up thinking it is the very reason why the bull tackles and fights the matador with the red cape.

Science, on the other hand, disagrees, because bulls are actually colour blind. Technically a bull cannot be pushed towards aggressive behaviour with exposure to colour red.

So what makes the bull go crazy is the million dollars question? It is the movement of the red cape, and not the red colour that agitates the bull.

2: Hair and Nails Grow after Death

We have been led to believe that our nails and hair keeps on growing even after we are dead. Most people think that the follicles supposedly continue to create new cell even when a person has died.

It turns out this is not true!

When someone dies, the decomposition process initiates, which does not allow the body to regenerate new cells. The process of decomposition leads to dehydration which makes the skin stretch. Hence the nails and hair seem longer to us.

3: We Have Five Senses

We have grown up believing we have 5 senses i.e. hearing, touch, smell, sight, and taste. It’s the first science lesson in the 1st grade.

Well, this is not true, because we have much more than just these 5 senses. Science has now further categorized our senses such as temperature, pressure and more.

4: Light Never Strikes Twice

Lightning never strikes at the same point twice – is what most of us believe don’t we?

Thanks to meteorologists now, we know this is entirely false.

Lightning can not only strike at one point twice but multiple times. According to latest scientific updates, the possibility of the lightning bolt striking at the same spot is not certain. Based on statistics, it can hit the same spot within ten minutes of its first stroke.

5: Cracking knuckles gives you arthritis


Cracking knuckles will definitely annoy the person next to you, but it will not give you arthritis. The major causes of arthritis, especially women are age, weight gain, genetics or injuries. Although cracking knuckles does not cause arthritis, but it may cause weakness in grip and swelling.

6: Alcohol Kills Brain Cells


Alcohol causes our nerve cells in the brain to die and malfunction. We have been told and taught from a very young age to believe that drinking alcohol results in the death of brain cells.

Good news for drinkers is that this fact is false. The bad news is that drinking alcohol does cause brain damage. If you drink alcohol to warm yourself up, you’re countering the bodies process, and you may be heating your body up further instead of cooling it down which can cause brain damage.

7: Tongue has 4 senses of taste

We have often seen diagrams and studied that our tongue can only taste 4 types of senses. Sweet, salty, sour and bitter. We can only taste them at different positions on the tongue and this has been believed for a very long time. But with the progress of science, we have now been able to prove that the tongue can taste many other tastes too and possess a lot of other tastes too. Also, the location of where the senses are more effective is also proved to be false. The tongue tastes the same any place on the whole tongue so this proved to be false as well.

8: Pruning Fingers ensure better grip

Early days of science led us to believe that the Pruning of the fingers and toes took place for us to keep our grip even when our body has been hydrated for a very long time. However, this theory was tested on people with different skin types and wet and dry extremities. The wrinkling of the skin was then proved to be caused because of narrowing of the blood vessels. When our body has been hydrated for a long time, the blood vessels in the body narrow and hence the wrinkling.

9: It takes years 7 years to digest gum

Since a very early age, we have been told never to swallow gum since it will stick in the intestines and will probably stay there forever. This has been believed for a very long time but studies proved that this is wrong, our body can’t actually dissolve gum so it gets out of the digestive system as it is. It comes out the same way it goes in. Our body can’t digest it so we just basically excrete it out of our body.

10: We must drink 8 glasses of water per day

We have to drink 8 glasses of water per day to maintain a proper and healthy metabolism. We have been told to drink a lot of water from a very early age and we have been advised to increase our intake of water with age to maintain proper body function and healthy metabolic rate. But this is not true, scientists have proceeded to test this theory and it is proved that a person may need only a little bit of water per day to maintain proper body function. It actually depends on the overall diet of the person, a person does not only get water from what he directly intakes, many foods, sodas and other things contain water too which easily become a part of our body and the water is absorbed from it and used by our body.
