Lying on the left is the correct sleeping position for pregnant women. The correct sleeping position of pregnant women will make pregnant women sleep soundly.
Generally, the heart is on the left, so it is best to lie on the right when sleeping, because it can relieve the pressure on the heart. Pregnant women, on the other hand, are just the opposite, because with the extension of pregnancy time, the uterus continues to grow, even occupying the whole abdominal cavity, which will squeeze the adjacent tissues and organs, and the uterus will rotate to the right to varying degrees, thus making the ligaments and mesangium that protect the uterus in a state of tension, and the blood vessels that provide nutrition for the uterus in the mesangium are also pulled, which will affect the oxygen supply of the fetus and easily lead to chronic hypoxia of the fetus.
If pregnant women take the left sleeping position, it can reduce the right rotation of the uterus, alleviate the lack of blood supply to the uterus, and be beneficial to the growth and development of the fetus and the production of pregnant women.
How do pregnant women sleep?
Many pregnant mothers complain that they can't sleep after pregnancy. How can pregnant women sleep well? In fact, the most undesirable thing is to sleep on your back. After a woman is pregnant, the uterus increases from about 40 grams before pregnancy to about 1200 grams in the third trimester, and with the weight of amniotic fluid and fetus, it can reach 6000 grams, and the blood flow of the uterus also increases accordingly.
If you lie on your back often, the abdominal aorta behind the uterus will be compressed, which will affect the blood supply of the uterus and the nutrition of the fetus. At the same time, it may also affect the blood supply to the kidneys, slow down the blood flow and reduce the urine output. Sodium salts and toxic substances produced by metabolism in pregnant women can not be discharged in time, which may lead to pregnancy poisoning, hypertension, edema of lower limbs and vulva, even convulsions, coma and even life-threatening.
When pregnant women sleep on their backs, they may also press the inferior vena cava behind the uterus, which will reduce the blood flowing back to the heart and affect the lack of blood supply and oxygen supply to the brain. Pregnant women will have dizziness, chest tightness, pale face, nausea and vomiting.
In the second and third trimester of pregnancy, if the pregnant woman often sleeps on her back, the uterus can also oppress the ureter, which makes the urination poor and prone to pyelonephritis.
How to sleep in early pregnancy
At the beginning of pregnancy, the fetus still lives in the maternal pelvic cavity, and the direct external pressure or self pressure is not very heavy, so the sleeping position of pregnant women can be arbitrary, mainly taking comfortable positions, such as supine position and lateral position.
However, if you have bad sleeping postures such as sleeping on your stomach and holding things, you should get rid of them as soon as possible.
What if I can't sleep well in the second trimester?
Many pregnant women can't sleep well in the second trimester, which is also related to the wrong sleeping posture. What is the correct sleeping position in the second trimester? When pregnant women sleep in the second trimester, they should pay attention to protecting their abdomen and avoid the direct effect of external forces.
If pregnant women have polyhydramnios or twin pregnancy, they should sleep in the lateral position, which can make pregnant women more comfortable, and other sleeping positions will produce oppression symptoms.
If pregnant women feel that their lower limbs are heavy, they can take a supine position and raise their lower limbs slightly with a soft pillow.
How to sleep in the third trimester?
The sleeping posture in the third trimester is very particular, especially lying posture, because the sleeping posture of pregnant women has an important relationship with the safety of themselves and the fetus.
It is advisable to lie on the left side in the third trimester, which can correct and increase the right rotation of the uterus, reduce the oppression of the uterus on the abdominal aorta and iliac artery, improve blood circulation and increase the blood supply of the fetus, which is conducive to the growth and development of the fetus.
It is not advisable to sleep on your back in the third trimester. Because when lying on your back, the huge uterus compresses the inferior vena cava, which reduces the blood volume and cardiac output, leading to hypotension. Pregnant women will feel dizzy, flustered, nauseous, suffocating and other symptoms, such as pale face, limb weakness, cold sweat and so on. If the above symptoms appear, you should immediately take the left supine position, and your blood pressure can gradually return to normal and the symptoms disappear.
Why do pregnant women sleep on their left side?
Why do pregnant women take a left sleeping position in the second and third trimesters? What are the benefits of pregnant women sleeping on their left side?
1. Lying on the left side of the pregnant woman can reduce the pressure of the enlarged pregnant uterus on the pregnant woman's aorta and iliac artery, maintain the normal blood flow of the uterine artery, ensure the blood supply of the placenta, and provide the fetus with the nutrition needed for growth and development.
2. Lying on the left side of the pregnant woman can reduce the oppression of the pregnant uterus on the inferior vena cava and increase the blood flow back to the heart. The increase of blood volume can increase the blood flow of kidney, improve the blood supply of brain tissue, and help to avoid and alleviate the occurrence of pregnancy-induced hypertension syndrome.
3. The uterus rotates to the right in the third trimester, and lying on the left side can improve the degree of the uterus rotating to the right, thus reducing the uterine vascular tension, increasing the placental blood flow and improving the oxygen supply state of the fetus in the uterus, which is beneficial to the growth and development of the fetus, and is of great significance to reducing the birth of low birth weight infants and the perinatal mortality rate. Especially in the case of fetal growth retardation, taking the left sleeping position can make the treatment achieve better results.
Therefore, lying on the left side of pregnant women is of great significance to prenatal and postnatal care and maternal and child health. If pregnant women have edema of lower limbs or varicose veins of legs, it is best to raise their legs appropriately when lying on the left side to facilitate blood return and reduce edema of lower limbs.
