In honour of Mother’s Day, here are a few amazing facts about women’s bodies you never knew.
They have stronger immune systems
It is commonly known that women live longer than men, and this could be very well due to the fact that the female body may be better at fighting off infections than the male body. Studies suggest that the female sex hormone estrogen plays a part in this, by curbing the expression of an enzyme that hinders the body’s defence system against bacteria and viruses. Researchers are not exactly sure why, but one probable explanation is that a stronger immune system developed over time because of the woman’s main role in giving birth and caring for her offspring.
They have better memory
Remembering the faces of people you have just met may be a challenge for many, but it may be apparently less so for women in general. Women have been found to be stronger in memory skills than men, as suggested in studies where they outdid men in memory tests. Their superior memory skills are not just limited to remembering things, like items on a list, but also faces of people as well. Other studies have found that women can remember faces better than men, as they unconsciously spend more time studying features of new faces.
They have better chances of surviving traumatic injuries
Another likely reason for women’s longer life expectancy could be the fact that they have higher chances of surviving injury and trauma. Researchers, in studying data on patients who arrived at hospitals with traumatic injuries, found that women in the age range of 13 – 64 were significantly more likely to survive. Again, the key to this advantage may lie in the higher levels of female sex hormones in women, which may have an enhancing effect on the immune system.
Their bodies are designed for remarkable changes during pregnancy
Perhaps some of the most fascinating changes that happen to a woman’s body come with pregnancy. From the size of an orange at the beginning of pregnancy, the uterus grows to about the size of a watermelon in 9 months. In addition, while most mothers know the pain of contractions, many probably don’t realise how much pressure is actually exerted during one. When pushing with a contraction, the force from a uterus equates to roughly 397 pounds of pressure per square foot!
Their bodies are structurally made for greater flexibility
When it comes to stretching and flexibility, women have an advantage in several ways. Firstly, their female muscles and tendons contain more elastin, the protein which gives our muscles, organs and skin the ability to stretch, and this gives them greater flexibility on the whole. More specifically, their lower spines are structurally different from men, having evolved to accommodate the load of carrying a baby for 9 months. The curvature of the lower spine spans across 3 vertebrae in the female body, but over only 2 vertebrae in the male body, giving them greater flexibility in that area. Lastly, due to evolutionary adaptation for childbearing, women have greater flexibility and range of motion in the pelvis area as well.
They have different circadian rhythms from men
Ever wonder how mothers always seem to wake hours earlier before the rest of the family? This may be because women could be more likely to be early birds than men. A study found that women’s body clocks follow a more easterly time zone, and as a result, awake and go to sleep earlier than men. They also need about 20 more minutes of sleep than men.
They have better muscle endurance
While men usually have the upper-hand when it comes to strength, it may be surprising to many that women may actually have better muscle endurance than men do. Research has shown that in stamina-related exercises, women were able to exercise for about 75% longer than men could. It is suggested that the presence of estrogen in women makes their muscles more resistant to fatigue, and that women have more efficient metabolism within their muscles as compared to men.
