People know that high temperature and pollution have influence on fertility, but few people think that noise is also a "fertility killer".
Studies have shown that high -intensity noise can damage the hearing, which has a varying degree of impact on nerves, cardiovascular, endocrine, digestion and other systems, as well as visual and intelligence.Especially in terms of endocrine, strong noise can cause hyperthyroidism in the thyroid function, leading to enhanced adrenal cortical function, increased basal metabolic rate, sexual disorders, etc., which will affect fertility function.
For men, under the noise of 70 & mdash; 80 decibels, the sexual function tends to weaken; living in an environment of 90 decibels, sexual function is easy to disorder.Higher noise can cause semen to not liquefy or cannot ejaculate.
Even after pregnancy, long -term exposure to strong noise will affect the central nervous system and digestive system function of pregnant women, leading to dizziness, headache, insomnia, aggravating early pregnancy reactions, and even led to drama vomiting or gastric ulcers.On the other hand, noise can also affect the growth of the fetus, leading to slow development, abortion, and premature birth. After birth, it is low body weight, weak and sick, and hearing after growing up.Chinese scholars have tested their children born to women who have a strong noise (more than 95 decibels) during pregnancy, and found that the noise during pregnancy can also cause the fetal IQ level to be low.The cause of this situation may be that noise often causes uterine contraction, affects the blood supply of the fetus, and then limits the development of the fetal nervous system.
It can be seen that noise pollution is not only harmful to fertility, but also adversely affects eugenics.Therefore, during the preparation period and pregnancy period before pregnancy, both husband and wife should try to avoid the noise environment as much as possible, and don't go to high -frequency environments such as karaoke and concert hall.If you cannot avoid environmental noise, you will enhance personal protection, such as wearing earrings or earplugs.
