Loud loudness during pregnancy can lead to negative effects on growing fetuses. Exposure to noise exceeding 120 dB may result in hearing loss in babies. Sudden and prolonged sounds can drive the child to increase activity. Harsh noises also cause fetal distress, birth weight loss, early delivery, and can alter the structure of the fetus's brain. The fetal heart rate decreases when music is played at lower decibels. This is a sign of music. As it is known in Sanskrit Hindi philosophy, what the fetus hears can affect his advancement and learning after birth.
As consumption of food directly affects the growth of your baby, there are other factors that make your child live well. Sound is one of them. Soft music calms the baby and mom and has a good effect. However, various studies on the effect of long noises on the uterine embryo show that loud noises during pregnancy can upset the baby.
The embryos get up to 25 weeks of hearing and respond to music until the 28th week. Babies can remember the music they have heard in the womb, and they seem to make better cognitive and motor skills, fast language development, longer life expectancy and better sleep, as well as colic (pain such as pain caused by insects, such as bees, and in Infants produce certain shapes) but do not work with loud sounds or unusual sounds, as it can affect the health of the child. The fetus can hear your voice from the 31st week of gestation. Babies remember the voices they heard in the womb and their effect on their learning.
If you read lullaby for your child, it's great because it can increase your relationship with your child. Recent studies show that infants who were in the womb and whose mothers were singing for them, were crying less than infants whose mothers had not seen it. Infants in the 2 months after birth had fewer cases of colic. They were awake less at night and mothers were less stressed.
The effect of music on the fetus
The fetal heart rate changes with music.
Embryos can grow and learn through music for 27 weeks.
The embryo begins to learn the language in the womb.
Pre-school music can make the child more accurate.
Affects the baby's hearing
The normal human ear can be up to 85 dB without damaging the brain nerves. Any sound above this level is loud and loud. The ear can hear up to 140 dB, but it is very painful and can cause permanent damage to the ear. With 24 weeks of pregnancy, the child's inner and outer ears are fully developed and can hear all the sounds that come to him. Exposure to more than 85dB of sound, up to 8 hours a day, usually created in high-tech workshops or factories, can reduce the hearing loss of the baby. Loud concerts produce between 110 and 120 dB sound, with exposure to it for more than an hour with similar effects.
Longer sounds that require the use of ear branches stimulate the baby. When the mother is near the airport or hears the siren several times a day, it causes a lot of ears. This can be seen with a sudden increase in fetal movements a few minutes after being exposed to noise.
Studies on rhizome monkeys were performed to detect the effect of loud sound on the fetus. Sustained exposure has shown increased levels of cortisol and corticotropin in the fetus. These are hormones that cause stress over time. The embryo does not display the symptoms of these hormones. Few cases of abnormal social behavior have been reported. Similar results are seen in mice.
However, embryo studies at this stage do not show changes in hormonal or blood composition. However, maternal lactose levels decreased significantly.
Can cause fetal disorders
Exposure to chronic exposure during pregnancy causes pressure and blood pressure in the mother, which affects the fetus directly. Research shows that congenital disorders are present in such embryos. They endanger their activity and compatibility. In addition, they also increase cortisol levels. Lack of weight at birth is another negative effect of exposure to long noises.
Increases the risk of preterm labor
Several studies were conducted to investigate the effect of long noises on maternal gestation. Studies have shown that the gestation phase has been reduced to 37 weeks, compared with 40 normal weeks. Some studies have not been resolved. Research in this area is still in progress.
Changing the structure of the brain of the fetus
Listening to conflicting or inappropriate music during pregnancy can significantly alter the structure of the fetus's brain. This is the result of a study on animals and a similar effect has been predicted on human embryos.
While full and definitive studies on the effects of long bouts of human embryos are still in progress, current information strongly emphasizes its negative effects. So, cut off the sounds around you and refrain from going to concerts.
