A recent research review has uncovered a striking connection between tinnitus, a persistent ringing or buzzing in the ears with no external cause, and one of the body’s most important restorative processes: deep sleep. With around 15% of the global population suffering from tinnitus—many experiencing significant distress, sleep disturbances, and even depression—this finding could signal new directions for symptom management and treatment for millions, including Thais impacted by this commonly misunderstood condition ScienceAlert.

A new review highlights a significant link between tinnitus—persistent ringing or buzzing in the ears with no external cause—and deep sleep, one of the body’s most vital restorative processes. About 15% of people worldwide live with tinnitus, and many endure distress, sleep disruption, and even depression. The findings could open new paths for managing symptoms and improving quality of life for millions, including Thais affected by this often misunderstood condition. Research by Oxford University neuroscientists points to shared brain activity during tinnitus episodes and slow-wave sleep, suggesting the brain’s sleep architecture may influence tinnitus intensity.

Hearing loss often develops gradually and quietly, but it is a growing health concern for ageing populations worldwide, including Thailand. New evidence shows that everyday choices—long exposure to loud noise and even common ear-cleaning habits—can speed up hearing decline. Genetics and ageing remain fundamental factors, but experts say much of the risk is preventable. With links between untreated hearing loss and dementia or depression, protecting hearing is increasingly important for Thai readers navigating environmental and lifestyle risks.

A new study sheds light on why certain people find it particularly difficult to follow conversations in noisy environments, identifying changes in a vital brain region known as the insula. Published this week in the journal Brain and Language, the research from the University at Buffalo shows that the left insula in individuals who struggle with “speech-in-noise” tasks works harder and displays altered connectivity—even when the brain is supposedly at rest—possibly explaining persistent listening difficulties as well as links to cognitive decline and dementia (Neuroscience News).

A new study sheds light on why some people struggle to follow conversations in noisy rooms by highlighting changes in a key brain region called the insula. Published in Brain and Language, the research from a major U.S. university shows that the left insula in people who find speech-in-noise tasks difficult exhibits stronger connections to auditory areas, even when the brain is at rest. This could explain persistent listening challenges and may relate to cognitive decline and dementia over time.
