Five interesting facts about the female body. The importance of proper nutrition

What do we know about human body? Basically what was remembered from school curriculum. However, our body is an amazing phenomenon and still holds many mysteries for scientists. Our body is a rather fragile system, which, nevertheless, can survive in different conditions.

We perceive our body as an integral part of ourselves, but we know very little about it. For example, men and women differ not only in external signs, character and behavior. Today we offer you a selection of amazing facts about female body, which you may not have even thought about.

25 most unusual facts O female body:

A woman's heart naturally beats faster than a man's.
Women blink twice as often as men.
A woman's body burns fat much slower than a man's - about 50 kcal per day.
Women have stronger immunity.
The diameter of a woman's hair is 2 times smaller than a man's.
The corpus callosum in a woman's brain is thicker than a man's. It contains 30% more compounds. This is what allows women to better cope with multiple tasks at the same time.
A woman's tongue has more taste buds.
Women have more pain receptors in their bodies, but thanks to estrogen, which blocks inflammatory processes, women in general have a lower pain threshold.
Women can distinguish shades and colors better, since color discrimination is directly related to the X chromosome.
Women's skin is 10 times more sensitive than men's.
The muscles and ligaments of the female body contain more elastin, so women are more flexible.
Women better than men can distinguish high-frequency sounds.
The activity of the female brain during sleep decreases by only 10%, so women's sleep is more sensitive.
Women can better distinguish between different shades of sweet taste.
Women by nature are less oriented in space, which can cause problems while driving. For example, 82% of men succeed in parallel parking, while about 70% of them can do it on the first try. For women, the results are completely different. Only 22% of women succeed in such parking, and only 1/3 of them can do it on the first try.
Women's speech is controlled by 2 think tanks. This is why women can easily pronounce up to 8,000 words a day, use about 3,000 sounds and 10,000 non-verbal signals. The same indicators for men are approximately 2 times lower.
Women naturally have a better developed sense of smell.
Women have better developed peripheral (side) vision, while men have better central vision.
A woman's neck is more mobile than a man's. When a woman is called, she usually simply turns her head, and a man in the same situation turns his whole body.
Baldness is an X-linked recessive trait that a man inherits from his mother.
Due to the presence of two X chromosomes, the female body is less prone to complications and chronic diseases.
Women are emotional by nature, crying on average approximately 30–60 times a year, and men 6–17 times.
About 30% of women may feel the urge to eat inedible things during pregnancy.
Women are more likely to feel anxious and insecure due to high level hormones progesterone, cortisol and estradiol. This is why women intuitively sense threat and danger better.
Women become more attached to men due to higher levels of oxytocin. Women also have more developed areas of the brain that are responsible for feelings of attachment.

Based on materials:

Nowadays, almost everyone knows about women’s monthly “problems”. As they say, from small to large. Acquaintance with the female body and its characteristics begins from school, and these are the paragraphs that are read long before the biology teacher asks them. This usually happens when the student is given a stack of textbooks for the next year.

Despite the increased interest from this young age of both boys and girls in issues of female nature, conception, pregnancy and childbirth, when the time comes, few parents are able to tell their growing child in a clear and accessible way (what is called “on the fingers”) about the menstrual cycle and everything else that goes with it.

Often in such situations, the child is given certain literature that describes in detail the changes in the girl’s body in puberty. This is quite justified; the main thing here is to choose competent and intelligible material. Sometimes this is done due to the “shyness” of the parents or their reluctance to talk with their offspring about “this” topic. But, unfortunately, in some cases this happens due to a misunderstanding of such issues by the parents themselves, including mothers who are faced with cyclical transformations of their bodies every month.

Let's try to at least partially understand what happens to a woman's body at a certain stage of her life.

To begin with, it would not hurt to clarify what the female cycle is. Everyone knows that the menstrual cycle is a cycle that repeats itself from month to month. various changes uterus, and vagina. But not only these organs! The mammary glands are also subject to cyclic changes, hair follicles, skin, bones, adipose tissue and the entire body as a whole. External manifestation these complex processes is menstruation.

Normally, the first period, or menarche, appears between 11 and 16 years of age. Since that time, it has been generally accepted that a woman’s body is capable of conceiving and carrying a pregnancy. This ability lasts on average up to 45-50 years, and sometimes much longer. Then there is a gradual "fading" menstrual function, which is most often expressed in a decrease in menstruation, a decrease in their duration and the volume of blood released during menstruation, up to their complete cessation. This period is called Om.

The first day of menstruation is considered the first day female cycle, its beginning, and the last day of the cycle is the day before next menstruation, from the beginning of which a new cycle begins. And don’t be alarmed if your cycle is shorter or longer than others. It's very individual. Normal cycle It is considered when at least 21, but not more than 35 days pass from the beginning of one menstruation to the beginning of another. In 60% of cases there is a 28-day menstrual cycle.

Another important characteristic of it is regularity, the absence of which is acceptable only for one to one and a half years after menarche. The duration of the bloody discharge(menstruation) normally ranges from 2 to 7 days. They should not be very scanty or excessively abundant; gynecologists believe that the volume of blood that a woman loses during these days is normally 20-80 ml.

It should be remembered that when normal course menstrual cycle a woman may feel some discomfort in the lower abdomen, in lumbar region, but should not experience significant pain.

Usually there are two phases of the menstrual cycle, conditionally separated from each other by the “birth” of the egg - ovulation. The appearance of this special cell of the female body occurs from a rounded formation with a complex multicellular structure - a follicle.

The body of an unborn girl already contains approximately 500 million follicles, of which only 10% of women receive at least some further development. The fate of the rest is to be on the “bench”, in reserve. Already by the time of menarche, the number of follicles is reduced by half from what was originally provided by nature. And only about 400 follicles during the entire period while a woman has her period reach their full development, ensuring the woman’s ability to conceive.

The first phase of the menstrual cycle is called follicular. It occupies the entire first half of the cycle, that is, from its first day until the rupture of the follicle with the release of the egg. That is, with a 28-day cycle, this phase, as a rule, lasts from the first to the fourteenth day. With the onset of the follicular phase, special cells in a woman’s brain undergo a series of complex biochemical processes they release a hormone into the blood. This is a follicle-stimulating hormone that acts on the ovaries, causing them to grow several follicles at once.

At first, the growth rate of follicles is approximately the same, but gradually one of them begins to outstrip the others and dominate. The rest, as if having lost “the hope of being first,” slow down their growth and gradually return to their original “rudimentary” state. The “leader” follicle, on the contrary, accumulates more and more “vital juices”,

grows and strengthens, sometimes reaching 2-2.5 cm in diameter. The role of this is very important education ovary - release of another hormone into the blood - estrogen.

The female body experiences the effect of estrogen even when it is in the “mother’s belly.” Mother's hormones, penetrating into the developing daughter organism, determine proper development girl's genitals. In other words, estrogens play a very important role during all periods of a woman’s life. It is to them that a woman owes her beautiful, smooth skin. They prevent the formation and excessive development of hair on skin. Estrogen (like progesterone) strengthens bone tissue, normalizes the functioning of the cardiovascular and other systems.

Here are some functions of estrogen:

development of secondary sexual characteristics of a woman during puberty (development of the mammary glands; special type hair growth and distribution of fatty tissue characteristic of the female body);
improve blood supply to the uterus;
promote the growth of the internal uterine lining (endometrium) in the first phase of the menstrual cycle;
raise sexual attraction women in the middle of the cycle, which corresponds to the moment the egg leaves the follicle, and therefore contributes to the implementation of the process of conceiving a child laid down by nature;
facilitate the penetration of sperm into the uterine cavity during the period of ovulation through the mucus located inside the cervical canal, as they reduce the viscosity of this mucus.

When the dose of estrogen in the blood reaches a certain level, the woman’s brain begins to produce another very important factor- luteinizing hormone. This leads to rupture of the follicle, that is, ovulation. This usually occurs in the middle of the menstrual cycle,

approximately on day 14.

Now the egg released from the follicle must get inside the uterus, which is only possible through a thin “petal” of the fallopian tube (fimbria), which, under the influence of the same estrogen, “lies” on the surface of the ovary exactly where the follicle ruptured.

Each healthy woman reproductive age short-term bleeding from the genital tract periodically occurs, which is commonly called menstruation.
The periodic onset of menstruation is associated with complex and varied cyclic changes occurring in a woman’s body. Knowledge of the female body and provision of complete and varied information about contraceptive methods are very important for the prevention of early pregnancy and for proper sex education of girls.
The whole complex of changes in the female body that occur cyclically and are externally manifested in periodically occurring menstruation is called menstrual cycle.
In practice, the beginning of the menstrual cycle is considered to be the first day of the next menstruation. And the duration of the menstrual cycle is the period from the first day of one menstruation to the first day of the next. The normal length of the menstrual cycle ranges from 21 to 35 days, with most women having 28 days. Duration of each menstrual bleeding is approximately 3-4 days, although may vary depending on many factors.

Regulation of menstrual function is carried out using 5 links:

* Cerebral cortex;

* Subcortical centers located mainly in the hypothalamus;

* Brain appendage - pituitary gland;

* Sex glands - ovaries;

* Peripheral organs - fallopian tubes, uterus, vagina.

Cyclic functional changes, occurring in a woman’s body, affect not only her sexual apparatus, but are also expressed in changes in the activity of the central nervous system,of cardio-vascular system, metabolic processes, thermoregulation, etc.

Ovaries- these are the female gonads that perform two important functions body:

* They undergo periodic maturation of follicles and ovulation, resulting in the release of female germ cell - egg;

* They produce female sex hormones: estrogen and progesterone, and
There are also small amounts of male sex hormones - androgens.

Both of these functions are closely intertwined and are an absolutely necessary component for the body to carry out the menstrual reproductive function.

Periodically, or rather, closer to the middle of the menstrual cycle, the follicle (the vesicle containing the egg) matures in the ovary; its dimensions are 2 cm in diameter. Under the influence of increased pressure inside the follicle, as well as under the influence of hormones, the follicle wall in the area of the free edge ruptures, and the egg is released into fallopian tubes, and then into the uterus. So-called ovulation occurs. When the wall of the follicle ruptures, a slight hemorrhage forms into the cavity, and the epithelial cells of the follicle begin to multiply, and in
accumulation of fat cells (lipids) occurs, which leads to the formation of the so-called corpus luteum.
If at the time of ovulation (the release of a mature egg from the follicle) fertilization has not occurred, then the corpus luteum undergoes reverse development and after a few days the inner lining of the uterus is shed (menstruation begins). Then the menstrual cycle repeats again. If fertilization has occurred, the corpus luteum continues to develop until 16 weeks of pregnancy, while producing hormones necessary for its preservation.

Follicle and corpus luteum are glands internal secretion that produce sex hormones. The follicle is capable of producing a number of sex hormones: estrogens, gestagens and androgens. During menstruation, the inner lining of the uterus - the endometrium - is shed and ruptures.
blood vessels that penetrate it. After the end of menstruation, the endometrium is restored through reproduction within a few days epithelial cells. This process occurs under the influence of estrogens produced by the follicle.

In the following days, an increase in the endometrial glands is observed, mucus is secreted, the inner layer of the uterus becomes loose and congested. This whole process occurs under the influence of progesterone, the hormone of the corpus luteum of the ovary. In the cessation of production yellow body progesterone, the endometrium is rejected again, the blood vessels open and
menstruation. In the ovary, the follicle matures again, which produces estrogens, and the entire uterine cycle repeats itself.
During the menstrual cycle, changes occur in the activity of all endocrine glands, the cardiovascular system, changes in metabolism, etc. For example, before and during menstruation, some women notice mood changes, irritability, a tendency to tan, enlarged mammary glands and etc.

Normal menstrual function is carried out as a result of the activity of many parts of neuroendocrine regulation. If one of the links in this chain is disrupted, menstrual cycle disorders of different nature may occur.

The reasons for such violations may be:

* Stress, mental and nervous diseases;
* Nutritional disorders (obesity, vitamin deficiency);

* Occupational diseases caused by exposure to certain chemical substances, radiation and much more.

Menstrual dysfunction may occur in different periods women's lives and clinically manifest themselves in different ways.
Amenorrhea- absence of menstruation for 6 months or more.

Algomenorrhea- disturbances of menstrual function, clinical signs which are sharp pain in the lower abdomen during menstruation, as well as the appearance before menstruation of the following symptoms: general malaise, irritability, pain in the mammary glands, a feeling of heaviness in the lower abdomen.

In case of any violations, you must consult a doctor. They may be signs of a serious illness.

People tend to experience a wide variety of feelings: love and hostility, joy, happiness and sadness. They arise in response to influence external factors. The body produces special substances - hormones that regulate the flow of biochemical reactions in its various parts and the transmission of impulses to the centers of the brain. Each person has his own set of these substances that affect his health, mood and temperament. An important role is played by the so-called joy hormones, which are responsible for positive emotions that make people cheerful and energetic.

What are hormones and neurotransmitters

Hormones and neurotransmitters are called biologically active substances stimulating work various organs when exposed to cell receptors. Hormones are produced in endocrine glands and by blood vessels spread throughout the body. They stimulate cells of various tissues to produce chemicals necessary for the occurrence of biochemical processes and the functioning of organs.

Neurotransmitters are produced in nerve cells. These substances transmit impulses directly to the brain, from where a response signal comes, forcing a person to make certain movements, think, digest food, and so on. There are biologically active substances mixed type, which manifest themselves in the body both as hormones and as neurotransmitters (for example, dopamine, norepinephrine).

Hormonal background and its features

A certain set of hormones is formed in the body, and their normal ratio is such that all organs work correctly and a person feels healthy. This does not mean that the combination of hormones should always be constant. The background changes within certain limits throughout life as one grows older and changes in physical and mental stress. The ratio of such substances depends on the gender of the person, his physiological state, age.

In men, the ratio is more stable. In women, due to the peculiarities of functioning reproductive system and monthly fluctuations in the level of sex hormones, it is constantly changing. It is thanks to this that representatives of the fairer sex are more excitable, capricious, and are characterized by frequent changes moods. Hormonal imbalance can lead to tumor diseases, sexual disorders, developmental pathologies, as well as depression.

Organs that produce happiness hormones

The main center that regulates the production of hormones of joy and happiness in the body is the hypothalamus. According to its signal, hormones are produced in the pituitary gland, thyroid, parathyroid, pancreas, adrenal glands, as well as in the ovary in women and testicles in men.

Cells that produce hormonal substances are also found in organs unrelated to endocrine system such as liver, kidneys, placenta, gastrointestinal tract and others. For example, when there is a lack of estrogen in the body, adipose tissue begins to produce them. In pregnant women, the placenta becomes the organ that produces hormones.

What substances are considered hormones of joy and pleasure?

There is a relationship between the production of various hormones and a person’s mood. His feelings and actions largely depend on how he slept, what he ate, with whom he communicated, and what new things he learned. The impressions he receives are reflected in the brain. And here signals are immediately produced that regulate the production of the corresponding hormones. Arises reciprocal feeling pleasure or disappointment, peace or angry indignation.

The main hormones of joy, satisfaction, pleasure and happiness are called:

endorphin;
dopamine;
serotonin;
oxytocin.

Substances such as adrenaline and norepinephrine directly affect a person’s behavior and mood.

Endorphin

Reduces the impact of negative factors.

This substance is produced in the pituitary gland at the moment when a person enters the stressful situation. Sharp increase endorphin concentrations in the blood lead to weakening painful sensations, easier to tolerate mental trauma, strength appears to overcome stress. Endorphin acts like opiates, bringing a person into a state of peace and happiness, mobilizing him, giving him a chance to think about the situation and make an adequate decision.

Improving the condition of the nervous system has a positive effect on the functioning of the heart and blood vessels, and helps strengthen the immune system. The level of endorphin in the blood increases sharply in women last weeks pregnancy. In this way, the body prepares to overcome the fear of childbirth and relieve pain. Endorphin “jumps” in athletes during competitions. It has been noticed that it is the surge of this hormone in soldiers that makes them brave and decisive during battle.

Its similarity to opiates, however, also plays a negative role, since this substance, like drugs, is addictive. If a person tries to artificially increase its content in the blood, he takes special means, then the production of your own endorphin decreases. To obtain pleasure and joyful emotions, everything is required high dose drug. In addition, an overdose easily occurs.

With a lack of the hormone of happiness, a person is apathetic, suffers from depression, and experiences anxiety. An overdose makes him aggressive, inadequate, and forces him to take unnecessary risks.

Dopamine

The hormone of satisfaction and joy.

It is produced in neurons of the brain and in adrenal cells. An increase in his concentration occurs even at the moment of planning something pleasant: a desired meeting, an interesting trip, or making a much-needed purchase. Dopamine levels reach a maximum when the result is achieved. This inspires him, makes him set new goals and strive to achieve them.

Thanks to the production of dopamine, people develop conditioned reflexes, food addictions.

Thanks to a surge in the content of this substance in the body, a person experiences satisfaction and happiness when listening to his favorite music. He is happy if his favorite team wins a football match. Dopamine levels rise sharply during sexual intimacy.

If there is not enough dopamine in the body, people are inactive, indifferent to studies, career growth, and prone to depression.

However, exceeding its content in the body is far from safe. This substance increases the frequency of contractions of the heart muscle and raises blood pressure. Long-term excessive consumption Dopamine drugs can lead to schizophrenia (auditory and visual hallucinations).

Note: The level of dopamine in the blood increases significantly with the consumption of alcohol, nicotine and cocaine, which increase its production several times. That is why drinking alcohol, smoking and using drugs allows a person to experience a temporary feeling of joy and happiness, enhanced artificially. But the fact is that each time more and more of this “stimulant” is required to get pleasure, and stopping its use leads to the appearance of “withdrawal” syndrome.

Serotonin

Hormone of happiness, antidepressant.

This substance affects the centers of the cerebral cortex, promoting optimism, a feeling of happiness, euphoria, and intoxication with one’s achievements. The centers responsible for memory are also activated, cognitive ability. Action of serotonin on receptors spinal cord leads to improved coordination of movements and increased muscle tone.

The production of the substance in the body increases under the influence of ultraviolet rays Therefore, in the autumn-winter period, when the days are shorter and the lighting is mostly artificial, people often experience seasonal depression.

As you know, there are synthetic antidepressant drugs. Their action is based on an artificial increase in the blood levels of neurotransmitter hormones, such as dopamine, norepinephrine, and serotonin. When treating depression and neuroses, they are taken for a long time. There is a great risk side effects(impacts hormonal substances on the heart, kidneys). With them misuse eye pressure increases, worsens mental capacity, sexual disorders arise.

Oxytocin

Enhances pleasure from communication and intimacy.

Produced in the hypothalamus. Once in the blood, it spreads throughout the cells of the entire body. This hormone strengthens a person’s attachment to his loved ones, as well as the desire to feel like “belonging” in a group. He enjoys a handshake from a friend he trusts. To be happy, a child needs his mother to hug him, stroke his back and head. The massage has a calming effect on him.

This substance plays a special role in the female body. Increasing levels stimulate the onset of contractions as it increases uterine contractility. Thanks to oxytocin, the mother feels a sense of reverence for her painfully born child, and he instantly calms down as he latch onto the nipple and pull out the first portions of colostrum. This is how the mother’s hormone gets to him, and mutual affection arises.

Adrenaline is an anti-stress hormone

It is produced at a moment of extreme danger. At the same time, a person is able to instantly mobilize, forget about pain and fear, and take risks for the sake of his salvation. His pulse increases sharply, that is, his blood circulation accelerates. The pupils dilate, so he sees better, and his hearing sharpens.

Norepinephrine – the hormone of peace and tranquility

Formed from adrenaline and helps reduce blood pressure, relieve spasms and normalize breathing. The person calms down and his mood improves. The formation of the hormone is promoted by listening to quiet, pleasant music, being in nature, and contemplating the seascape. The less norepinephrine, the more adrenaline and anxiety associated with its presence.

The role of sex hormones

The most important role in the body is played by the sex hormones estrogens and testosterone, thanks to which men and women develop external features. These substances are produced in individuals of both sexes. But the female body contains tens of times more estrogen, and the male body contains tens of times more testosterone, which explains the behavioral characteristics of men, their physical endurance, and sexual activity.

Estrogens

In women, estrogens are produced in the ovaries after the onset of puberty. If there are enough of them, the girl develops correctly, her breasts form, her hips increase. Beautiful figure, good hair and skin, a gentle voice bring pleasure to any woman. Thanks to estrogen, she is sexually active, capable of childbearing, and arouses interest in men.

If there is little estrogen, it worsens appearance, happens rapid aging body, menstrual disorders occur.

Wanting to prolong youth and enhance sexuality, some women take synthetic estrogens, risking their health. Hyperestrogenism causes infertility, tumors of the genital organs and mammary glands.

Testosterone

The presence of a small amount male hormone in a woman’s body makes her independent, confident in her righteousness and uniqueness. At the same time, a “strong” woman remains fragile, tender and easily vulnerable.

There is a saying: “The world is ruled by men, men are ruled by women, and women are ruled by hormones.” Loving man He will take this into account and be lenient towards small “female weaknesses.” Excess testosterone leads to changes in appearance, voice and character male type, is a pathology that requires serious treatment.

Other hormones needed to enhance feelings of joy and happiness

Other substances can also be named hormonal action that can enhance feelings of pleasure and happiness:

Vasopressin. It is involved in the regulation of water-salt balance, which directly affects the condition of hair and skin, the presence of signs of external attractiveness and health, pleasing to the eye.
Acetylcholine. Promotes development creativity, intelligence and memory. Thanks to him, a person is able to rejoice and experience a feeling of pride and happiness when he manages to cope with a difficult task. Helps maintain dignity and mental balance.
Melatonin – regulator biological rhythm. Normalizes night sleep, helping you to fully relax after a hard day.
Somatotropin is a growth hormone. Increases muscle elasticity, improves joint condition, prolongs youth. It is important to prevent its overdose in the body, as this can lead to a pathology such as gigantism. If a child is deficient in the hormone, he may remain a dwarf.

How to increase the level of joy hormones in the body and feel happiness

There are many drugs available that contain synthetic hormones of happiness. Sometimes it is simply impossible to do without them. For example, estrogen-based products help in the treatment of infertility, and also improve the quality of life by alleviating the symptoms of menopause.

However, we must never forget about harmful consequences overdose. There is much more safe ways increasing the content of hormones of joy and happiness in the body and enjoying life.

The importance of proper nutrition

With food, the body receives substances containing either hormones directly or substances that stimulate their production. Delicious and healthy food always improves your mood. For example, to get rid of autumn-winter depression, you need to eat dark chocolate, fruits (especially leaning on bananas, pineapples, apples), and drink coffee. They contain tryptophan, an essential amino acid involved in the formation of serotonin, melatonin and others. useful substances. Tryptophan is also found in foods such as avocados, coconuts, figs, strawberries, and beans.

Foods that need to be consumed to increase the content of joy hormones in the body also include tomatoes, kiwi, nuts, plums, eggs, meat, and milk. Everyone knows how candy, baked goods, honey and other sweets have a beneficial effect on the mood.

While comforting yourself with food, we must not forget that overeating is no less harmful than a lack of joy hormones. A person who tries to suppress despondency with the help of sweets or cakes may develop obesity. The circle closes: eating sweets improves your mood, but spoils your figure, which adds worry and stress.

Exercise stress

This is probably the safest and most useful way improving mood and achieving happiness. Vigor of body and spirit are inextricably linked. It has long been known that if feelings of anger and indignation are bursting, it is useful to chop wood, do major cleaning, or load yourself with other work.

Long walk physical exercise, jogging is an excellent way to escape from worries. In addition, when exposed to the sun, the body produces vitamin D, which accelerates the synthesis of happiness hormones.

Deep sleep

Dream - best medicine from all diseases, including mental trauma. It gives strength, radically changes the mood in better side. It’s not for nothing that they say that “the morning is wiser than the evening.” A person who sleeps soundly increases the level of serotonin, melatonin and other hormones in the body that are necessary for restoration of strength.

Doing what you love

Mental stress and achieving set goals also require the body to increase the production of dopamine and other hormonal substances. Receiving moral (and material) satisfaction is no less important for a person than other joys of life.

Sex and pregnancy

Sexual satisfaction, explosion positive emotions caused by intimacy, like nothing else, stimulate the production of substances necessary for the emergence of feelings of pleasure, happiness and love. The level of sex hormones, oxytocin, serotonin at this time is unusually high.

Nothing makes a woman as happy as the feeling of future motherhood. All experiences recede into the background. the main objective is about preserving your own health and peace of mind, necessary for normal development baby. During this period there is abrupt change hormonal levels, increased production of substances necessary to maintain positive attitude. Pregnancy and love for a child gives a woman such strength that allows her to survive any sorrows.

To feel calmer, to feel the joy of life and happiness, you need to make every effort to experience the love of loved ones and the respect of others. It is necessary to set realistic goals and strive to achieve them.

Photos from open sources

Even though the woman is a mystery, scientific facts about the female body can clarify a lot in attempts to unravel it.

1. Diameter women's hair half that of men. And this, despite all the efforts of women to care for their hair, neither hair botox nor all kinds of masks can change genetics.

2. A woman's heart beats faster than a man's.

3 Women blink twice as often as men.

4. A woman’s attachment to a man is stronger than a man’s to a woman. Therefore, women, as a rule, are more eager to start a family. This is due to increased levels of oxytocin, as well as the fact that women have better developed parts of the brain (ventral putamen, nucleus pallidum and the frontal part of the brain), where long-term attachment is concentrated.

5. Women burn fat slower than men - by about 50 calories per day.

6. Women have stronger immunity.

7. The corpus callosum in women's brains is thicker than men's and has 30% more connections. This is why women are better at multitasking.

8. A woman's tongue has more taste buds.

9. Women have more pain receptors, but because estrogen blocks inflammation, women are generally better able to tolerate pain.

10. Women are better than men at distinguishing colors, since color discrimination is directly related to the X chromosome.

11. Women's skin 10 times more sensitive than men's.

12. Female breast does not contain muscle tissue.

13. Women's muscles and ligaments contain more elastin than collagen, which is why women are more flexible.

14. Women are much better than men at distinguishing high-frequency sounds.

15. The electrical activity of the female brain during sleep decreases by only 10%, therefore woman's dream more sensitive.

16. Women are better than men at distinguishing shades of sweet taste.

17. Women worse than men orient themselves in space. 82% of men succeed in parallel parking, 71% succeed on the first try. For women, the results are disastrous. Only 22% can do this, 2/3 of them will not do it on the first try.

18. Two brain centers are responsible for speech in women, so a woman can easily pronounce up to 8,000 words a day, use up to 3,000 sounds and up to 10,000 non-verbal signals. The same figures for men are two times lower.

19. From birth, women have a better developed sense of smell than men.

20. 80% of women have one breast (usually the left) larger than the other.

21. Women have well-developed peripheral vision. For men - tunnel.

22. Women's breasts react to temperature. The heat makes it softer and the nipples enlarge.

23. Time is coming female orgasm- from 10 to 20 minutes. On average, four minutes is enough for men.

25. Baldness is an X-linked recessive trait that males inherit from their mother.

26. Due to the presence of two X chromosomes, women are less likely to experience complications and chronic diseases.

27. Women cry on average from 30 to 64 times a year, men only 6-17 times.

28. 30% of women have a craving for non-edible things during pregnancy.
