A neurologist has issued a serious warning about a widely practiced sleep habit that could elevate your risk of dementia. Dr. Baibing Chen, known as Dr. Bing, shared insights that have significant implications for brain health and hearing.
Dementia is a condition marked by a progressive decline in brain function, leading to symptoms such as memory loss, behavioral changes, and personality shifts. While it primarily affects those over 65, dementia is influenced by modifiable factors beyond age.
Research indicates that around 45% of dementia cases are preventable through healthy lifestyle adjustments. One critical, yet often overlooked, factor is hearing health.

In a widely viewed TikTok video, Dr. Bing explains why he never wears headphones to bed. He warns that using headphones or earbuds during sleep poses several risks: prolonged exposure to loud sounds can damage the delicate hair cells in the inner ear, increasing the chance of hearing loss. This hearing loss has been strongly linked to a higher risk of developing dementia.
Moreover, wearing earbuds or headphones for extended periods can trap moisture and bacteria, raising the risk of ear infections. Loud sounds during sleep may also disrupt deep sleep stages, interfering with the brain’s lymphatic system, which clears toxins nightly and supports cognitive health.
Dr. Bing emphasizes that even mild hearing loss is a substantial, yet often neglected, risk factor for dementia. He urges people experiencing hearing difficulties to seek medical evaluations promptly and consider hearing aids if recommended. Maintaining auditory health helps keep the brain active and engaged, which may reduce dementia risk.
Supporting his viewpoint, a 2024 study published in The Lancet identified hearing loss as one of the most significant modifiable risk factors for dementia. Dr. Bing also recommends other lifestyle changes to protect brain health, highlighting the crucial role of hearing care in dementia prevention.
If you or someone you know experiences symptoms such as memory decline, confusion, or hearing difficulties, consulting a healthcare professional without delay is essential for appropriate diagnosis and intervention.
