The information you can mistakenly believe

You often hear information about your body and health. But will all the information you know be true? The answer is: No. There are things we think are right, but according to scientific studies, it is not so. Here are things we often mistakenly believe or have not been scientifically proven.

We only use 10% of our brains

Are they only using 10% of their brains? People have believed it for more than 100 years. But what we believe is completely wrong.

Recent brain scan results with CT and MRI techniques show that all areas of our brain are active, more or less. That proves that more than 10% of our brains must work regularly.

Safe to eat food that falls on the floor?

For many people, it seems harmless to eat food that has just fallen to the floor in less than 5 seconds because they think that time is not enough for bacteria to cling to food. But studies have proven this to be completely wrong.

The results of the experiments showed that the bacteria (mainly Salmonella) can penetrate food that has fallen to the floor in less than 5 seconds. Therefore, you cannot apply the '5 seconds' rule to foods that fall to the floor. The best way is to put them in the trash.

Nails and hair continue to grow after people die

Many say that a few days after death, hair, nails, and nails continue to grow. These changes in the dead are observed through grave excavations. However, doctors insist this is not realistic.

When a person dies, all of the body's fluid that helps the skin expand will begin to evaporate with adipose tissue and other fluids. As a result, the skin becomes dry and hardened. Therefore, the body's hair, nails, and toenails appear to be long rather than extra. All life-sustaining biochemical processes stopped immediately after the person stopped breathing, so there was no possible change in the body outside.

Blue nasal discharge is a symptom of sinusitis

Many people believe that the color of nasal fluid is a different pathological manifestation. For example, if the nasal fluid is yellow and turns green, you will think it is a manifestation of sinusitis and need antibiotics. Even many doctors often diagnose the disease according to the color of the nasal fluid.

However, scientific studies show that the color of nasal fluid is not sufficient to help diagnose whether you should take antibiotics. This is very important, because taking antibiotics when not sick can cause side effects and drug resistance.

Eating at night increases weight

Some health magazines often recommend that people who want to lose weight should not eat at night. This seems reasonable when arguing that you eat at night, your body will not have enough time to burn off calories during sleep because the body needs less calories.

However, many studies have shown that the time you eat doesn't affect weight gain. The main factor affecting your weight is the amount of calories you 'load' into your body. For example, a study with 2,500 people found that eating more than 3 meals a day puts you at greater risk of being obese.

Therefore, to lose weight effectively, you only need to eat less calories than your body needs and you don't need to bother to eat.

Influenza vaccination can be infected with the flu

This is completely wrong because flu vaccines use dead or weak viruses that are no longer capable of causing illness. Therefore, the flu vaccine cannot make you sick with the flu. It is possible that some people mistakenly believe that side effects after vaccination such as headaches and mild fever are symptoms of the flu, but they are not.

Dog's mouth is cleaner than human mouth

You can see some people kissing their beloved dogs, because these people think that the mouth of dogs can be cleaner than human mouths. According to previous studies, it has been shown that bites from bites are more susceptible to infections than bites.

But a recent study has shown that this is only true for hand bites. This study also showed that the amount of bacteria in human and dog mouths is similar.

Severe vaccine causes bowel syndrome

A bowel syndrome is a phenomenon in which the inside of the abdomen is protruding at a point of the abdominal wall. Men are more likely to have this condition than women. The position of the bowel is usually located near the groin, or it may swell in the scrotum area.

The bowel syndrome is usually caused by increased abdominal pressure after heavy lifting, coughing or trying to push at bowel movements. In some people, a muscle point in the abdominal wall has been weak since birth.

To prevent bowel disease, you should: use appropriate lifting techniques and avoid lifting things that are too heavy for you; avoid constipation and do not try to push when urinating; quit smoking, especially if you have a chronic cough.
