It turns out these 10 superstitions work! No wonder they believed in this before, oh no wonder...

Our world is full of myths and incredible theories. It is impossible to say that superstitions are complete nonsense, because they arose not from scratch, but from long-term observations of the surrounding world.





Many such superstitions are hard to believe, but from time to time scientists make another discovery, and it turns out that the fairy tale is not a lie and not a hint, but a proven scientific fact.

Modern myths

1. Eat fish, you'll be smart!
   Grandma always said that, and I didn't believe it. However, researchers have found that children who eat fish at least once a week have a higher IQ and have fewer problems falling asleep. This conclusion was reached by American experts from the University of Pennsylvania, whose article was published in the journal Scientific Reports. They found that children who ate fish once a week or more had an average IQ of 4.8 points higher than those who ate fish at all.
   
   People often hear that they should eat more fish, but not everyone understands why. One of the benefits of eating fish is that fish contains large amounts of omega-3 fatty acids. These acids are extremely important for brain development.

2. An apple for dinner - no doctor needed
   Scientists from the University of Wisconsin found that apple skin contains a large amount of antioxidants. It is thanks to these substances that apples do not allow the formation of prostate cancer in men, and breast cancer in women. Researchers recommend eating apples with the skin daily.

3. A tedious birth will be a boy
   Studies show that boys need more time than girls to meet our world. This is due to the fact that boys have bigger heads and are usually heavier than girls. Mothers expecting boys are more likely to have complications during childbirth.

4. Fruit juice is not good for children
   Citric acid is often added to fruit juices, and this substance destroys enamel. The result is caries. Fruit juice is also unable to quench thirst. It includes a large amount of sugar and causes allergies and gastrointestinal problems. The proteins it contains can also cause enterocolitis. It is best to limit juice intake to 1 cup per day. And the best way to quench thirst is pure water.

5. Cheese causes strange dreams
   Ebenezer Scrooge of Dickens' Christmas Song blamed cheese for his nightmares. Although the hero of the story eventually got better, the idea that cheese can affect dreams is still quite common. But does it have any scientific basis?
   
   
   
   A few years ago, there was evidence from one study that showed that different types of British cheeses can cause dreams. Fans of Stilton (a type of blue cheese with mold) had strange dreams, fans of red Lester dreamed of the past, and those who at night tried Lancashire cheese, on the contrary, saw in a dream the future.
   
   This phenomenon can be associated with one substance that is contained in cheese - tryptophan. This amino acid is present in many foods, particularly milk, chicken, turkey and peanuts. From it, our body produces serotonin, which is responsible for a calm mood and healthy sleep.
   
   
   
   
   
6. Lovers of hot baths waiting for infertility
   The negative impact of high temperature on reproductive abilities has long been known: the first studies on this topic were conducted in the middle of the last century. It turns out that under the influence of temperature exceeding normal for the body, sperm motility decreases, and this, in turn, leads to infertility. By the way, at the beginning of the last century, a hot bath was considered a quite effective method of contraception, although this method did not always work.

7. Chocolate heals a broken heart
   Scientists say chocolate is good for the heart. How does chocolate affect such an important organ? Immediately it is necessary to make a reservation that only the use of dark chocolate, otherwise called bitter, will benefit. After all, polyphenols, which are contained in large quantities in cocoa beans, have a beneficial effect on the work of the cardiovascular system. Chocolate is certainly not a cure for cores.
   
   And to restore the normal functioning of a sick heart, he is not able to. But it is quite possible to prevent some problems by consuming bitter chocolate.
   
   
   
   
   
8. Walnuts will remove scratches on furniture
   This is one of the most useful stories. All you have to do is remove the nut from the shell and rub it with scratches on furniture or wooden floor. The oils present in the nut will quickly smooth out scratches on the surface.
   
   
9. Count the sheep, you'll fall asleep faster.
   It is not known where this tradition came from. According to some assumptions, the myth came from shepherds who counted sheep before going to bed to make sure that the whole herd was in place. Knowing that all the sheep were safe was supposed to calm them down and help them sleep. Experts say that fall asleep - It's an individual matter. It does not matter what you imagine before going to bed, the main thing is that it relaxes you. Accordingly, if you are a fan of sheep and mathematics, then this method may well suit you.
   
   
   
   
   
10. Fluoride can harm your teeth
    Dentists recommend using fluoride toothpaste as an effective method of preventing tooth decay. However, recent research in New Zealand suggests that fluoride actually does more harm than good. Once fluoride enters our body, it can disrupt the brain, nervous system, gastrointestinal tract, kidneys and liver. Fluoride can also accelerate the natural aging process and increase bone fragility.
    
    Fluoride compounds have a tendency to accumulate in tooth enamel. After exceeding the required dose, a destructive process can begin - fluorosis. The main symptoms of the disease are the appearance of white spots and spots on the tooth surface.
