The human anatomy is quite amazing really, with all the utterly jaw-dropping things your body can do being both incredibly fragile and amazingly sturdy. It's delicate simplicity, and intricate complexity all contained within one being and working together to make you who you are, and between each human being, there are some subtle and not so subtle differences.Some of the starkest differences come between men and women with many being more than insignificant and not all of them visible at first sight. Here we look at 25 amazing facts about the female body we bet you didn't know!
1. Women's Hearts Are Programmed To Beat Twice As A Fast As A Man's
The female heart is quite different from the male heart in many different ways, but one of these is that it is smaller to fit into the, typically, narrower frame. As such, the heart has to beat twice as fast to pump around the same amount of blood to the body.
While the average weight of a woman’s heart is 118 grams a man’s heart weighs 60 grams more and they also have veins that are an average of 1 mm thinner than men’s making them harder to work on.
2. Women Blink Twice As Often As Men Do
The hormone of estrogen is far more prevalent in the female body and is associated with fertility and procreation but it also regulates the lubrication in the body, and this includes the lubrication of the eyeballs. Women on birth control pills (or estrogen supplements) who have elevated levels of estrogen blink even more frequently, up 32% more often, than other women.
Similarly, women going through the menopause can suffer from feeling as though their eyes are dry due to having less lubrication. This is perhaps why batting one's eyelashes is seen as a form of flirting as it is hormonally linked to fertility.
3. Women Burn Fat Slower Than Men
Typically speaking, women tend to burn 50 calories less than men a day, and this is because men tend to have larger organs and thus require more energy to keep them going, as such men burn through more calories than women.
This also means that men can eat more than women and have a higher recommended calorie intake.
4. Women have A Stronger Immune System
Women tend to have a stronger immune system, and this has been a long documented and accepted fact, but the mechanisms behind it remain unclear. One study suggests that testosterone regulates certain genes related to health and that the less a person has, the more the immune system is likely to 'overreact'.
Another study suggests that health genes are predominantly held in the X chromosome and by having two X chromosomes as opposed to men's X & Y gives women the immunological advantage.
5. Female Muscles Typically Contain More Elasticin, Which Makes Women More Flexible
Men typically have stronger bones and can build muscle better than females whilst women tend to be leaner and outperform men regarding flexibility. This is due to evolutionary advantages lent to motherhood and recovery time as women also tend to heal quicker than men.
Testosterone increases everything from size and mass of the muscle to the male skeletal. Whereas estrogen in women's bodies keeps the muscle mass in check, making them lighter and more flexible.
6. The Corpus Callosum in the Female Brain is Larger, Allowing Women To Multi-Task Better Than Men
It is not a myth, women, typically, are better at multitasking, or switching from one task to another and back again, due to the part of the brain that processes organization being larger. This is called the Corpus Callosum, and no one is quite sure why it is bigger, but there are many theories as to why this may be the case.
The most prominent seems to be the evolutionary theory, the hunter-gatherer hypothesis which invokes a 'traditional' image of women in the home where women would cook and tend to the infants, with men out doing so-called "linear" tasks such as chasing and killing prey.
7. There Are More Tastebuds On The Female Tongue
Women tend to have more taste buds on their tongues than men and also have a more sensitive palate. This sensitivity is then further increased when women reach a childbearing age as they become more susceptible to sharp, sweet and bitter tastes.
One theory behind this is that women developed the evolutionary trait of becoming better at identifying toxins, either because of the hunter-gatherer roles or because it serves that more women needed to be able to identify toxins for the survival of the human race, i.e. woman carry the children and so more are needed than just the men who impregnate.
8. Women Have More Pain Receptors But Have A Higher Threshold For Pain
Women have more pain receptors than men and thus tend to feel pain more intensely. This has been suggested to be an evolutionary advantage as a form of protection or desire to protect young from similar pain.
That being said, thanks to estrogen, which blocks inflammatory processes, women tend to have a higher pain threshold meaning that they can cope with this pain better.
9. Women Are Better At Distinguishing Between Shades of Color
It has been found that women are often better at distinguishing shades of color and this is because color perception is directly linked to the X chromosome, which women have two of as opposed to men's X & Y chromosomes.
This, like the distinguishing of tastes, has been linked to the possible evolutionary advantage of detecting threats.
10. Female Skin is Twice As Sensitive Than Male
Women tend to have more sensitive skin than men and are also more sensitive to touch and thus can often distinguish finer detail with their hands. Testosterone increases the thickness of the skin which is why men tend to have 25% thicker skin.
Also, after puberty, sebum production is greater in males than females, which is attributed to androgen secretions and accounts for why men have longer lasting acne.
11. Women's Hairs Is About Half The Diameter of Men's
On average, women’s hair is about half the diameter of men’s hair making male hair much coarser than that of female hair which is thinner and finer.
Hair length and quality can act as a cue to a woman’s youth and health and, as such, signify reproductive potential.
12. Women Can Hear Higher Frequency Sounds Better Than Men
Women can pick up higher pitched sounds far more clearly than men and are also more susceptible to react to it. This is largely thought to be due to maternal instinct and being in tune to higher frequencies plays into the idea that they are more likely to react to a crying baby.
Evolution has made women more sensitive to high pitched noises so that they can better care for their offspring. In the middle of the night, or during the day for that matter, a woman’s ears would be more receptive to the crying of a baby.
13. A Woman’s Brain Activity Lowers Only 10% During Sleep
A woman’s brain activity lowers only 10% during sleep which is far lower than a man's and again this is because of the evolutionary advantage of being easier to wake when caring for young.
As such, women may find they need to spend longer in bed, especially around menstruation periods due to hormones and pain also affecting sleep balances.
14. Women Have Two Brain Centers Responsible For Speech
Women have two brain centers responsible for speech and processing spoken words as opposed to men who have just the one.
As such, women can use about 3000 sounds and 10,000 nonverbal signals – twice as many as is available to men.
15. Women Have A Better Developed Sense of Smell
Males and females greatly differ in their perceptual evaluation of odors and women have around 50% more olfactory cells.
Some believe this olfactory ability is essential for reproductive behaviors such as pair bonding and kin recognition, but this has yet to be definitively determined.
16. Women Have Better Peripheral Vision
Women have better peripheral vision than men, whereas men, typically, can focus better on something directly ahead of them. This is, again, linked with the hunter-gatherer notion of evolution.
Women needed a better peripheral vision for scavenging and detecting threats while men had a stronger straight-on vision for hunting purposes.
17. A Female Neck Is More Flexible Than A Male's
When a woman hears her name called, she turns her head. A man typically turns his entire body.
This is to do with the lumbar support of the spine, and how women are more flexible for childbirth but, given that the head is attached to the spine and how this support aligns, women's heads are therefore more mobile.
18. Women Are Worse At Spatial Orientation
It is not a stereotype, in general, women do tend to be worse at spatial orientation. For instance, 82% of men can parallel park, with 70% of this number getting it right on the first try. With women it’s an entirely different picture: 22% of all female drivers can parallel park, and only 1/3 of them can do it on the first try.
That is not to say men are better drivers, as women tend to notice specific landmarks more and navigate in such a fashion whereas men, typically, recognize the layout of an area more so. Also, scientists note that women outperform men at other tasks. For example, women are more likely to spot which of a group of objects has been moved to a new position. It is not fully known why this is the case.
19. Women Are More Likely To Feel Anxiety
Women are more likely to feel anxiety because they have naturally higher levels of progesterone, cortisol, and estradiol.
That’s why women are better at predicting threats and dangers intuitively, and it has been suggested this has come about via evolution.
20. Baldness is an X-linked Recessive Trait Inherited by Men from Their Mothers
Baldness is typically found in the X chromosome and, as such, a lot more men go bald than women as they inherit the two X chromosomes whilst women only inherit the one.
That being said, baldness is found in around a third of women, it is perfectly natural and nothing to worry about.
21. Women Are More Emotional Than Men
It is a stereotype that women are more emotional than men, but it has been found that, typically, women cry on average 30–60 times per year while men cry 6 to 17 times.
However, there is no definitive evidence to suggest this is solely a genetic thing but more of a societal pressure as men tend to feel pressure not to cry, whereas women find it more acceptable. Strictly speaking, this would mean that women aren't more emotional but are more comfortable showing their emotions.
22. When Pregnant, 30% of Women Will Feel the Craving to Consume Inedible Things
Usually in the first trimester, peaking in the second trimester, many women will crave particularly sweet or salty foods that are affected by the culturally available cuisine of the region. This is largely due to a shift in hormonal balances, and so the body starts to crave certain foods to try and rebalance this.
However, around 30% of women will crave inedible things, this is called Pica, but there is no known reason as to why this occurs.
23. Women Can Form Stronger Attachments
Women form more powerful attachments to other people because of higher oxytocin levels.
They also have better-developed brain areas that are responsible for the feeling of affection.
