Eat vegetables, sleep 8 hours a day, exercise - this is the generally accepted view of what is good for everyone. In fact, the human body is much more complex than we think about it.
Guided by what is useful and what is not for the human body and organism, we often focus on outdated knowledge or the experience of generations, which it is high time to abandon. Here are 10 of the most common facts about the human body that are actually not true.
1. Humans only use 10% of their brains
Weighing about 1.4 kg, the human brain contains almost 100 billion neurons. They transmit information to each other through gaps called synapses - there are about a quadrillion of them in the brain.
The three main parts that make up the brain are the cerebrum, the cerebellum, and the brainstem. The first controls the work of 85% of all other human organs, the cerebellum is responsible for coordination and balance, and the trunk regulates all automatic functions, such as breathing or digestion. And for all this, the brain needs only 10% of its capabilities? Scientists have long refuted this claim, although it is still popular. 10% of your brain is involved only when reading this paragraph.
2. It takes 7 years for the stomach to digest gum.
Many remember this horror in childhood, when, having accidentally swallowed gum, you heard that the gastrointestinal tract will now digest it for seven years. If you are in the process of doing this right now, exhale with relief, this fact is complete nonsense. Of course, chewing gum is an indigestible food. In official documents, the product is defined as a "non-nutritional chewable substance" (that is, not like food). It is not recommended to swallow chewing gum, but if this does happen, it will simply leave the body in approximately the same form in which it entered it.
3. Chocolate is bad for the skin
Puberty and adolescence alone is reason enough for skin problems, but many girls are convinced that the true cause of acne is in the chocolate they eat. Yes, frequent consumption of high-fat and high-sugar foods can actually increase your body's sebum production. But the direct relationship between chocolate and acne is nothing more than a myth. Teenage acne often just needs to be experienced, while trying to eat right.

4. Carrots improve night vision
This is a myth that has survived since World War II, when British soldiers were told that carrots would improve their ability to see in the dark. Carrots are indeed a source of beta-carotene, which during digestion turns into vitamin A, which has a beneficial effect on vision. But does this improve night vision? No. All the carrots in the world can't affect it. And it is unlikely that German intelligence bought into the myth of the superpowers of British soldiers. But the rest of the world believed in the miraculous power of carrots.
5. We have five senses
Sight, hearing, smell, touch, taste - these are the five human senses that were formulated back in the time of the Greek philosopher Aristotle. Thousands of years have passed since then, and now scientists are sure that a person has much more feelings. Thus, the sense of touch is much more complex than just one sensation. A person perceives the force with which they touch him, feels the temperature of the object, pain. Now we can talk about at least 33 different feelings inherent in man. These include, for example, blood pressure and balance. So the next time you hear someone talk about their sixth sense, feel free to say that you have 33 of them.
