Adult hearing can be harmed by noise levels of 85 dB or above, according to the US Centers for Disease Control and Prevention. As a consequence, based on the findings of research and the CDC's guideline, it is preferable to restrict your exposure to noises lower than 85 decibels in order to minimize bad effects on you and your fetus (5). Noise from music players, computers, and other devices is one of the most common sources of noise during pregnancy. Studies have shown that listening to these types of noises at high volumes can lead to increased stress hormones in pregnant women, which may affect their baby. If you do need to use a device with speakers, try using headphones instead. Also, make sure that any home equipment that uses batteries is out of reach of your fetus. An unborn child cannot control the flow of current through his or her body, so if you leave them exposed to electric currents, there is a risk of injury or death. Last but not least, avoid using household chemicals and cleaning products without knowing how they affect babies. Some products contain ingredients such as alcohol, acetone, or benzene that could be harmful to an infant's developing organs. Other products may produce toxic gases when they break down under high heat or pressure, such as when cooking food or using a hair dryer. Test all chemicals before use in case some should not be used during pregnancy.
