What is the most intolerable thing about sleeping at home on the weekend? Many people will answer in unison: noise!
The impact of noise on modern people has made many people feel gritted teeth. Renovation noise, square dance music, car horns, ugly musical instruments... If there is a pregnant mother in the family, the noise is really like a murderous weapon.
The impact of noise
The definition of noise is the sound emitted when the emitter does irregular vibration, and we usually say that noise mostly refers to the sound that should not be in a certain environment. Noise hinders people's normal rest, study and work, which will cause people to be emotionally irritable, and the volume is too strong and even endangers the health of the human body.
Not only that, but studies have also shown that noise is extremely harmful to people's eyes. When the noise is 90 decibels, the sensitivity of rod cells in people's retina to distinguish light brightness begins to decline, and the response time to recognize weak light is prolonged; When 95 decibels is reached, the pupils are dilated; When 115 decibels is reached, the eye's adaptability to light brightness decreases.
The impact of noise on pregnant mothers
The impact of noise on pregnant mothers is great. First of all, noise will directly interfere with the quality of sleep during pregnancy, and make pregnant mothers become irritable, which will increase the possibility of pregnant mothers suffering from pregnancy-related hypertension to a certain extent. Secondly, if the pregnant mother is affected by noise for a long time, it will cause endocrine dysfunction and the pituitary gland secretes too much oxytocin, which will cause the uterus to contract strongly, which can easily lead to miscarriage and premature birth. In addition, noise can exacerbate the phenomenon of vomiting during pregnancy and increase the frequency of morning sickness.
Effects of noise on the fetus
Some people think that the fetus has not yet developed a full sense of hearing in the mother's body, and because it is protected by the mother, it will not be disturbed by noise. But in fact, the fetus can hear the sound outside the uterus around 17 weeks of pregnancy, but at this time the hearing is still very fragile, if the pregnant woman is in a noisy environment for a long time at this time, it will bring great harm to the fetus.
The most direct impact of noise on the fetus is to interfere with the normal development of the fetus, including the physiological development of the fetus, intellectual development and hearing.
A mainland study compared the children of female workers exposed to strong noise (more than 95 decibels) during pregnancy with other children with similar conditions and found that the former had lower IQ levels than the latter. It is speculated that noise often causes uterine contractions, affecting the blood supply to the fetus, which in turn affects the development of the fetal nervous system.
A foreign survey of residents living near international airports also found that the weight of babies born to local residents was lower than that of newborns in other regions, indicating that strong noise is likely to affect the development of the fetus.
There are also some studies that show that pregnant women play prenatal music in an incorrect way during pregnancy (more than 100 decibels), which increases the likelihood of hearing loss in newborns and impairs the auditory development of the fetus.
How to avoid the impact of noise on the pregnant mother and fetus
For pregnant mothers, it is not advisable to work or live in places where the noise is too loud, and at the same time, usually avoid going to some places that are prone to high notes, such as theaters, KTV, etc. In life, pay attention to the volume when the appliance is in use.
If you want to carry out prenatal education for the fetus, do not play music and increase the volume at will, which will be counterproductive, and you should master the scientific prenatal education method to avoid the fetus in a high-pitched environment.
There is a lot of noise in life, and pregnant mothers need to take the initiative to stay away from noise, and at the same time, they should not create high notes that the baby does not like, and create a comfortable nurturing environment for the baby.
