Do we know everything about our own body? Anyone who is sure of the depth of this knowledge is mistaken. The human body – it is a complex and mysterious mechanism that hides many oddities and often baffles both the luminaries of medicine and the scientific world. The human body is capable of performing dozens of amazing and at the same time obvious actions, but we do not know about all of them.
Many are scientific fact, but a reasonable explanation is not always found for them. And, of course, the intrigue does not disappear. Science is doing everything possible so that the veil of secrets in this area of the universe rises higher and higher. But still, there are more than enough strange and mysterious facts. Read about them in the article on estet-portal.com.
Women really get colder than men
As for subcutaneous fat, it is just more in women, however, it is concentrated in the center of the body and warms the internal organs. Therefore, the hands and feet are not so protected from the cold, and when they get cold, it feels like the whole body is freezing. Also, in women, the threshold for susceptibility to cold is an order of magnitude lower. Thus, at the same temperature, the blood vessels in women's fingers are more constricted than in men; so it turns out that hands get colder more.
Does a person need fingerprints
It was previously assumed that papillary patterns on the fingertips are necessary for a person in order to hold objects. But scientists from Manchester adhere to a different version. They are sure that the unique patterns on the fingers only hinder this goal (due to such patterns, the contact area between the fingers themselves and the surface of the objects held is reduced).
Researchers believe that the grooves on our fingers are endowed with a protective function, serving as a kind of "screen"; for the formation of corns and protecting from damage.
Teeth are displaced even if the person has no orthodontic pathology
There is an opinion that with age, the bone tissue becomes denser and, accordingly, the teeth become immobile and their displacement is possible only with the help of mechanical action. But in fact, teeth move over time. This is mainly due to the loss of bone tissue behind the gums. A similar process occurs during aging, however, inflammation in the periodontal tissues and smoking can significantly increase it.
In the event of the disappearance of a large amount of bone tissue, the teeth just move.

The human body and its reaction to weather changes
Such a statement has the right to life. The fact is that the onset of inclement weather, as a rule, is accompanied by a decrease in atmospheric pressure. And the human body reacts to these fluctuations: there is an expansion of tissues, which, in turn, entails the appearance of pain, swelling, tumors.
Temperature also has a certain influence. In particular, American scientists have found the following: when it drops by 10 degrees, many people with joint health problems experience increased pain in the knees, which is osteoarthritic in nature.
It should be noted that when the weather changes, swelling of the tissues is often not so pronounced, however, people with arthritis and joint problems may be more sensitive to this effect.
With age, a person's feet increase
Our ligaments and tendons become weaker over time. Therefore, the arch of the foot takes on a flattened shape, while in this case they themselves become longer and expand. People with swollen ankles, as well as diabetics and those who are overweight are more susceptible to this. As a rule, when a person approaches the life "threshold" 70–80 years old, his lower limbs are getting one size larger.
The human body – an incredibly complex and amazing mechanism, the possibilities of which are not fully disclosed. And how much the scientific world still has to learn, how much to discover, to understand, in order, among other things, to treat diseases that are not amenable to therapy today.
Well, the researchers keep revealing themselves to us so that the strange facts about the human body cease to be such.
