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.
Tinnitus is often associated with hearing loss and is considered a “phantom perception”—an experience of sound generated by the brain itself. Unlike the fleeting auditory illusions most people might perceive while falling asleep, individuals with tinnitus endure these phantom sounds constantly throughout their waking hours. The persistence of these symptoms not only affects concentration and quality of life but also undermines mental health, contributing to heightened stress and risk of depression, especially over months or years.
In recent years, sleep researchers have taken a closer look at the mechanisms underlying tinnitus, and their findings are shifting scientific understanding. The review, authored by neuroscientists at the University of Oxford, highlights the parallel changes in brain activity that occur in both tinnitus and sleep. During slow-wave sleep—commonly called “deep sleep” and considered the most restful stage—distinctive electrical waves sweep across different areas of the brain, helping to restore neurons and consolidate memories. Interestingly, the same brain regions that generate perception of sound are engaged during both tinnitus episodes and deep sleep, prompting researchers to examine how these states interact.
The review suggests that for people with tinnitus, certain brain regions may remain hyperactive even during periods when the rest of the brain is supposed to be at rest, much like the activity patterns observed in conditions such as sleepwalking. This persistent activity could explain why tinnitus sufferers often report poor sleep quality, frequent awakenings, and a preponderance of light, non-restorative sleep. In fact, studies consistently show that those with chronic tinnitus spend less time in restorative deep sleep compared to those without the condition.
However, there’s a silver lining: the researchers found evidence that during the deepest phases of slow-wave sleep, brain activity patterns may actually suppress the perception of tinnitus. This could explain why even those with severe tinnitus can sometimes experience moments of true rest at night. According to the review, “the more neurons in slow-wave mode together, the stronger the drive is for the rest of the brain to join,” suggesting the brain’s natural sleep architecture may be able to quiet the phantom noise, at least temporarily.
These findings are significant in Thailand, where tinnitus is frequently observed among older individuals—particularly those with a history of loud noise exposure, such as traditional drummers, temple performers, and workers in the manufacturing sector—as well as younger people using personal audio devices at high volume PubMed. Despite the high prevalence, many Thais remain unaware of the link between sleep quality and tinnitus severity. Bangkok-based otolaryngology specialists have observed that patients getting insufficient or fragmented sleep tend to report more distress from their symptoms.
Expert opinions reinforce this potential therapeutic link. A doctoral researcher in neuroscience at the University of Oxford, who led the review, explained, “Investigating how tinnitus changes during sleep could give us a direct handle on what the brain does to cause fluctuations in tinnitus intensity.” Meanwhile, a Thai hospital sleep medicine specialist has observed, through clinical practice, that patients taught to improve sleep hygiene—such as regularizing bedtime and reducing caffeine intake—often report improvement in their tinnitus burden, even in the absence of a cure.
Current recommendations for managing tinnitus in Thailand emphasize the importance of holistic care. While there is no known cure, interventions such as sound therapy, counseling, mindfulness training, and sleep optimization are standard components of multidisciplinary treatment. For example, at leading sleep clinics in Bangkok and Chiang Mai, combining cognitive-behavioral therapy with lifestyle adjustments and periodic hearing assessments has yielded promising results.
Historically, Thai culture has approached conditions like tinnitus through both biomedical and spiritual lenses. Village elders sometimes prescribe herbal remedies such as ginger tea or holy basil, while Buddhist temples have hosted mindfulness-based meditation sessions specifically targeting insomnia and stress—practices now being validated by modern neuroscience for their benefits to sleep and emotional regulation.
The reviewed research also points to promising avenues for future treatment. Sleep restriction paradigms, where patients are encouraged to only go to bed when truly sleepy, have been shown to boost slow-wave sleep—potentially strengthening the brain’s own ability to suppress tinnitus. In addition, the use of wearable technology that tracks sleep stages and tinnitus perception could help researchers and clinicians fine-tune interventions.
However, challenges remain. The relationship between other sleep stages, such as rapid eye movement (REM) sleep, and tinnitus is not yet fully understood. Inconsistent access to specialized sleep and tinnitus care in rural areas of Thailand also limits the reach of these new insights. Moreover, stigma surrounding “imaginary” symptoms still discourages some from seeking help. A public health expert at a provincial hospital in Isan notes that, “Many elderly patients believe tinnitus to be a normal part of aging and don’t recognize the impact poor sleep has on their bodies and mood.”
How can individuals in Thailand act on these findings? First and foremost, awareness is key. Those experiencing persistent ringing, humming, or buzzing in the ears—especially if accompanied by sleep problems or mood changes—should consult a qualified doctor, preferably at an ear, nose, and throat clinic with access to sleep medicine expertise. Practicing good sleep hygiene—such as going to bed at consistent times, avoiding screens before sleep, and limiting alcohol—may help quiet both the mind and the ears. Participation in community-based mindfulness meditation or yoga sessions, widely available in Thai cities and temples, may further support restful sleep.
Routine check-ups for hearing loss, particularly for individuals exposed to workplace noise or those over age 50, can help identify reversible contributors to tinnitus. Early intervention tends to yield better outcomes. Since tinnitus can also be aggravated by stress, leveraging social support—through family, religious communities, or professional counseling—remains a valuable strategy ingrained in Thai society.
Looking ahead, further research combining sleep stage monitoring with real-time tracking of tinnitus could pave the way for custom-tailored therapies. As global awareness rises, Thai clinicians, public health authorities, and community leaders will need to collaborate on educational initiatives and expand access to multidisciplinary care.
For now, the science offers an encouraging message: while tinnitus remains a challenging condition, our very need for sleep may hold the key to relief. Making small, positive changes to sleep habits could offer tangible benefits for thousands of Thais living with the constant echo of phantom noise.
