7 Unexpected Changes That Happen in a Woman’s Body After Childbirth

A woman’s life changes
drastically after childbirth because she has to bear responsibility both for
herself and her baby. Big changes occur in a young mother’s body — scientists
claim that she becomes a chimera since the cells of a newborn baby can stay
with her for the rest of her life.
Bright Side learned how a
woman’s body changes after it has delivered a new human to this world.
1. The voice changes.

The voice of a woman who gives
birth to a child changes — it becomes lower and more monotonous. That’s the
conclusion the scientists from the University of Sussex came to. One year after
childbirth, a woman’s voice goes back to its initial frequency.
Researchers suggest that these
changes are caused by hormonal changes. That’s because the level of sex
hormones drastically decreases after childbirth and it can affect the vocal
cords. According to scientists, the maximum voice height of a woman who gives
birth falls to 44 Hz or 2.2 semitones. This equals approximately 2 piano notes.
However, this change has
another explanation as well. Experts believe that people with a low voice, as a
rule, are considered more competent and mature. That’s why women can
subconsciously change their timbre in order to adjust to their new role of a
2. Anxiety increases.

Young mothers are often told
that they should stay calm and peaceful, however, the truth is that it’s impossible.
Usually, a woman who gives birth to a child becomes scared and worried about
everything like if the baby is crying, if the baby isn’t crying, if the baby is
sleeping too much, if the baby isn’t getting enough sleep, etc. But this is
normal. It’s not the woman who is extremely nervous but rather the oxytocin
hormone that keeps increasing her levels of anxiety.
Oxytocin starts to intensively
secrete right after childbirth. It helps the uterus that had stretched during
the pregnancy shrink down and it also switches on the maternal instinct.
Another hormone called progesterone is responsible for the relaxation of the
nervous system and can help in this situation but it is at its lowest level
right after childbirth. Therefore, young mothers will have to adjust to the
fact that they will feel like they’re going crazy because of their anxiety
right after giving birth to their child.
There is an advantage to this:
oxytocin is also called the hormone of love and it lets a woman feel that
incredible tenderness towards their newborn. This feeling is worth all the
anxiety that comes with it.
3. The brain works better.

Scientists have found that
women become smarter after childbirth. The brain becomes bigger in order to
meet the needs of not only its owner but the baby’s needs as well. That’s the
reason why young mothers can be better workers than their colleagues who don’t
have kids. “Being able to be more efficient in your decision-making, being
emotionally resilient, maybe being able to engage in different strategies to
solve a problem… that sounds like a wonderful executive or manager to me,”
says Kelly Lambert who studies women’s brains during and after pregnancy.
The neurobiologist Craig
Kinsley notes that not only is giving birth to a child a big event in a woman’s
life, it’s also a big stage in her mental development, which is as important as
the teenage stage in life.
4. The body becomes ready for
a new pregnancy.

A woman’s immune system
decreases drastically during pregnancy — it’s required in order to prevent the
body from rejecting foreign fetal cells and miscarriages. It’s regulative
T-cells that are responsible for the fetus’ life in the uterus making sure the
mother’s immune system doesn’t reject it. Scientists have found that these
cells remain in the mother’s body for another 4 to 5 years after delivery and
they are ready to mobilize the body as fast as possible in case a new pregnancy
That’s the reason why women
often confess that it was much easier for them to carry the second baby- all because
their immune system was fully ready for it, while it had to make an enormous
effort and work harder during the first pregnancy.
5. A connection with the baby
is formed on a physical level.

The physical connection a baby
has with its mother doesn’t stop after birth. Scientists from the University of
Alberta in Canada found that babies’ cells can remain and function in the woman’s
body. They analyzed the brains of women who gave birth to boys and discovered
male cells in 63% of the cases.
The researchers came to the
conclusion that the cells of the child can penetrate through the placental
barrier into the mother’s body and continue to function there. By the way, male
cells in a woman’s brain can decrease the risk of Alzheimer’s.
6. The body gets renewed.

It’s all because of the blood
of the fetus — it starts the regeneration processes in the mother’s body.
Embryonic cells help a pregnant woman to heal wounds and can even prevent and
heal serious diseases. For example, a liver biopsy of a pregnant woman with
hepatitis C who stopped treatment showed improvement. Scientists found that the
source of her liver’s cells were the cells of the fetus.
Additionally, pregnancy can
prolong life but mostly in cases when the pregnancy occurs later in life.
Scientists found that women who had kids at an older age lived longer than
others. At the same time, the age of the first pregnancy and fertility weren’t
related to life expectancy in women. The same results occurred while exploring
the Amish community in Pennsylvania.
7. The risk of cancer

The mechanism that protects
women from some cancer types “switch on” after childbirth in a woman’s body.
For example, women who give birth to their babies at a younger age have a lower
risk of getting ovary cancer and endometrium. The risk decreases with every
full-term pregnancy. Girls who became mothers before 25 and breastfed their
babies are less susceptible to breast cancer.
