How long does the fetus who is pregnant for 22 weeks sleep a day?

It has been some time since the fetus reached 22 weeks. At this time, the fetus weighs about 350g and is 19cm long. The eyebrows and eyelids of the fetus are clearly distinguishable, and delicate nails have grown on the little finger of 10. Many pregnant women are very concerned about the sleep of the fetus in their stomachs, so how long does the fetus who is pregnant for 22 weeks sleep a day? Let's have a look.

How long does the fetus who is pregnant for 22 weeks sleep a day? Some mothers think that fetal movement is consistent with their schedule. When mommy wakes up, the fetus will start to move, and when she is ready to sleep, the fetus should be quiet.

In fact, babies sleep 90% of the day.

The fetus is in the mother's belly, and it is also very particular about the rules of work and rest. Generally, babies don't like long sleep. Their sleep cycle is usually 20-40 minutes. After waking up, they will wake up for 5-20 minutes and then go back to sleep.

24 hours a day, they sleep 90% of the time, that is to say, for the fetus, there is no difference between day and night, they are always between sleeping and waking.

Although the little guy sleeps so long a day, he is not "sleepy" When awake, he will be an energetic little rascal, chewing his fingers, "doing gymnastics", playing with umbilical cord, swimming in amniotic fluid and kicking your feet from time to time. His little life is also colorful!

1, playing with umbilical cord

Besides sleeping, the fetus likes to play, but in his mother's womb, he doesn't have any toys, and the only thing worth mentioning is the umbilical cord. It was originally a passage for mothers to deliver nutrition to the fetus, and the fetus regarded it as a "toy" by the way, circling around the umbilical cord and playing with it. Take a rest when you are tired of playing. When you are full of energy, you will play harder and harder, but you don't know that there is danger lurking here. In the process of playing, some fetuses are entangled in the umbilical cord, which leads to danger.

Step 2 burp

Can the fetus burp? It sounds like a joke, but it's true. Pregnant mothers will find rhythmic fetal movements in the late pregnancy, which will appear several times a day. From a medical point of view, this is the sound made by the baby when swallowing amniotic fluid, and it is also that he is "practicing" breathing movements to make the lungs mature faster, so the fetal hiccups are not really hiccups.

pee

Will the fetus pee in the mother's womb? This is not particularly clear to many people. Studies have shown that the fetus actually urinates in the mother's womb. The fetus grows up day by day in the womb, and the most important thing every day is to swallow amniotic fluid. Research experts believe that fetal urination itself is a physiological process and an essential function for growth and development. If the fetus just swallows amniotic fluid without discharging it, it is like filling a balloon with water, which will eventually burst. After the second trimester of pregnancy, the amount of amniotic fluid largely determines the urine volume of the fetus. So there must be something wrong with the fetus not urinating. If your amniotic fluid is less than normal, you should consider whether there is something wrong with the fetus' kidney, especially the urinary system.

Do pregnant women sleep more? After pregnancy, in order to create a good environment for the fetus, we must ensure adequate sleep time. Pregnant women sleep much more than normal people, at least 8 ~ 9 hours every night and at least 1 ~ 2 hours at noon every day, but the time should not be too long. At the beginning of pregnancy, the body of pregnant women has not changed much. During this period, the fetus still lives in the maternal pelvic cavity while developing in the uterus, and the direct pressure of external force will not be very heavy. There is no need to overemphasize the sleeping position of pregnant women, and you can choose comfortable sleeping positions at will, such as supine position and lateral position.

During pregnancy, if the mother can sleep soundly, the pituitary gland in the brain will secrete growth hormone during sleep. This is not to help the mother grow, but to secrete for the growth of the fetus, which is an indispensable substance for the growth of the fetus. In addition, this hormone also helps mothers to quickly eliminate physical and mental fatigue. Many mothers often complain that they can't sleep well before pregnancy, but it becomes easier to fall asleep after pregnancy because they release the hormones they need and naturally change their bodies.

It seems that it is difficult for modern people to work at sunrise and rest at sunset, but pregnant women should develop good sleep habits, go to bed early and get up early, don't stay up late and keep full of energy. There is also a need to change the bad sleeping posture in the past, such as sleeping on your stomach or holding something, because sleeping on your stomach or holding something will cause abdominal pressure, lead to fetal malformation, and more seriously lead to miscarriage. Generally speaking, the first month of pregnancy is difficult to detect, so it is best to develop good sleep habits before planning pregnancy, so as not to affect the growth and development of the fetus.
