6 'tin duck' can now still believe you

Development science, many old conclusions have now become duck news. But not many people know that.

In the past, humans have made quite subjective assumptions, only based on observation to explain some strange events and phenomena.

Over time, the development of science and technology has helped us turn these hypotheses into . duck news. However, if not a person who regularly updates the news, perhaps many of us still believe in these untrue rumors.

1. Sugar causes hyperactivity

For a very long time, many people believe that sugar and sweets are capable of making us excited, uncontrollable. In particular, children are the easiest . to be crazy when eating too much sugar.

The only thing that can change is the expectation of the opposite.

However, in 2014, some studies completely dismissed this conclusion. Accordingly, cases of high sugar consumption have no changes in psychology, thinking and even activities within the brain.

In fact, the only thing that can change is the expectation of the opposite. Parents who believe in eating sugar will cause hyperactivity, so when their children eat, they expect to see them playful. But the truth is they are inversely all the time, everywhere, not just when eating sugar.

2. The brain is for creative people

Many people have so far believed that the right side of the brain is for handling things related to imagination and art, while the left brain serves logic calculations and language processing.

People use both alternate hemispheres of the brain, with no difference.

In fact, that is true. However, this does not mean that people with "creativity" use the right brain more, or logic people use the left brain.

According to studies, there is no scientific evidence to support this conclusion. Furthermore, studies have shown that people use both alternate hemispheres of the brain, with no difference.

3. Warm up helps to avoid muscle pain after playing sports

This is absolutely not true. Up to 12 studies show that starting before exercise only has a very small effect in reducing muscle pain after exercise.

Even some studies show that booting has no effect on avoiding injury. However, these studies do not have clear evidence that it is best to start. Be careful not to worry!

4. You should drink 8 glasses of water a day

Since the 1940s, some studies have shown that our bodies need to load 2.5 liters of water a day - converted into 8 cups of water. And since then, we have always followed without knowing that this is not really necessary.

The reason is that 2.5 liters of water comes from both the food we absorb every day, or in drinks like coffee.

In addition, there is no scientific evidence that is strong enough to show that if you do not drink 2.5 liters of water, you will experience symptoms of dehydration, because the level of water consumption of each person is different.

Each person's level of water consumption is different.

However, you should still drink about 1.5l to 2l of water every day, because nutritionists recommend it.

5. We are only using 10% of the brain's ability

For a long time, scientists have upgraded our brains, thinking that humans have only explored 10% of the brain's latent potential.

Every part of the brain has its own function.

But the truth is that if you only use 10%, you won't be sitting here reading this article. Many studies have shown that every part of the brain has its own function, and we are forced to use it all to function smoothly.

This is also the reason why the brain is not allowed to harm, for any reason.

6. Shave hair regularly to make hair grow thicker and longer

Many people still have the idea that shaving their hands and feet without radicals will make you quickly become a forest man. This story is passed down from generation to generation, as an immutable reality.

The thickening of the hair is just a feeling.

In fact, this has been scientifically dismissed by a study since 1928. More specifically, scientists believe that this is just a coincidence, because shaving boys and girls have waxed hair removal. early in puberty. But now, the hormones also increase, affecting the thickness of the hair.

Moreover, the thickening of hair growing is just a feeling. That's because when you have fur, you will give the coat a sharp and rough surface, which makes them feel thicker.

In short, it's all duck news.
