Babies and sleep have always been a delicate combination. For decades, parents have relied on white noise to help their little ones drift off to dreamland. But a growing concern is emerging: this popular technique could be doing more harm than good. According to experts, white noise might be stunting a baby's language development, potentially leading to a "public health issue."

Dr. April Benasich, a sleep expert at Rutgers University, is sounding the alarm. She warns that the monotonous tone of white noise can interfere with a baby's ability to develop a strong language network in the brain. This network is crucial for language learning and understanding. By exposing babies to constant, unvaried noise, parents may be hindering their child's ability to process sounds and set up new networks.

The brain's neuroplasticity is most active during sleep, when it absorbs information and adapts to experiences. Babies sleep for 12 to 18 hours a day, which means they're being exposed to white noise for an extended period. This can lead to the brain becoming desensitized, thinking there's nothing important happening, and thus not setting up new language networks.

Benasich's concerns are backed by research. Studies have shown that children who are exposed to white noise for extended periods may have delayed language development. But despite the warning signs, many parents remain loyal to white noise. Benasich attributes this to a lack of understanding about the brain's development during sleep and a reliance on unverified information from social media and influencers.

Instead of white noise, Benasich recommends using soundscapes with variation, such as ocean waves or a heartbeat. These sounds can provide a soothing background without interfering with a baby's language development.
