Pregnant women work in a noisy environment

For many pregnant mothers, pregnancy is of course a matter of great concern. However, in addition to paying attention to the health of the fetus during pregnancy, many pregnant mothers also pay attention to things that are harmful to the fetus. Maybe you know that diet, lack of exercise, and indiscriminate medication are harmful to the baby during pregnancy. Then, are you aware that being in a noisy environment for a long time is also harmful to the baby in the belly?

Noise is extremely harmful to the fetus because high-pitched noise can damage the fetus's auditory organs. Severe noise pollution will have unexpected adverse effects on fetuses with weak awareness of noise. Scientific research has confirmed that fetuses who have been exposed to strong noises above 85 decibels have lost the sensitivity of their auditory systems before they are born.

Because the fetus's inner ear is in the process of development, it is very susceptible to harm from low-frequency noise (low-frequency noise: generally refers to the sound with a frequency below 500HZ). The low-frequency sound in the external environment can be transmitted to the uterus and affect the fetus. Studies have shown that noise stimulation to the fetus' ear canal can damage part of the brain and seriously affect the growth and development of the brain, causing children to develop intellectual disabilities.

Scientific research shows that if pregnant women live in a noisy environment for a long time, they will experience mental anxiety and endocrine imbalance; the central nervous system will be excited, catecholamines will be released, vascular inflammatory hormones will increase, and blood pressure will rise, resulting in fetal ischemic hypoxia, fetal intrauterine distress, and in severe cases, fetal malformations or even miscarriage. During pregnancy, the ideal noise environment is no less than 10 decibels and no more than 35 decibels. If pregnant women stay in noise (50-80 decibels) for more than 2 hours a day, they will feel irritable and anxious, and their breathing and heart rate will increase. Especially for pregnant women with high estrogen and thyroid hormone metabolism, it may cause damage to the digestive function, which may cause fetal malformation.

It is not difficult to see that noise can cause serious harm to the fetus. Therefore, pregnant women must be aware of the noise around them and try to avoid noisy environments. If they have to work in a noisy environment, they must take necessary measures to reduce noise damage.
