Certain medications can make tinnitus worse

Musicians are 57% more likely to have tinnitus compared to the general public

Musicians have four times the risk of developing hearing loss, and their risk of developing tinnitus is increased by more than half.

There's no cure for tinnitus, but sometimes it goes away on its own

Though there's no cure, treatments and management approaches can significantly reduce symptoms and improve quality of life. Hearing aids, sound generators, and other steps can help some people with this condition. But sometimes tinnitus resolves within hours or days for reasons that remain unclear.

People with tinnitus should avoid silence—sound-rich environments distract the brain

This podcast from an audiologist discusses common questions about tinnitus. It notes that tinnitus could be described as a phantom sound associated with hyperactivity in the brain. It's linked with loud sound exposures above 85 decibels, hearing loss associated with aging and stress, among other factors.

Tinnitus is a rare side effect of COVID-19

The infection can affect inner ear cells, and a review of the literature across multiple studies concluded that hearing loss occurred in 3.1% of patients with the virus and tinnitus in 4.5%.

Ludwig van Beethoven suffered from tinnitus

Historical figures that reportedly had the condition include Charles Darwin and Beethoven. Both men wrote letters about the frustrations and pain they experienced from the condition. (Some users may experience a paywall.)

A new tinnitus therapy involves mild electric tongue shocks and sound exposures

Lenire, an FDA-approved bimodal neuromodulation treatment approach for tinnitus, aims to teach the brain to distract itself from tinnitus. It includes short-term daily sessions wearing a mouth device that delivers mild electrical pulses to the tongue while listening to different sounds. (Some users may experience a paywall.)

If hearing is damaged, the brain may amplify remaining sounds, perhaps causing tinnitus

Recent mouse brain and ear imaging revealed that the creature compensates for hearing loss by sending signals to the cochlea in the inner ear. This triggers nerve fibers in the inner ear to increase volume and become more sensitive. Learning about these boosted-sensitivity messages from the brain to the cochlea—if they're similar in humans—might help explain tinnitus and fuel experimental approaches to turn down that sensitivity.

Pulsatile tinnitus is when you hear thumping synchronized with your heartbeat

This rare type of tinnitus, which sounds like rhythmic thumping or whooshing, is often linked to blood vessel conditions or high blood pressure. Lowering blood pressure through exercise and food choices can help reduce the severity of this condition.

Tinnitus is derived from the Latin verb tinnire, meaning to ring

Hear examples of what tinnitus can sound like to those suffering from it

This video, from a Scottish branch of the UK National Health Service, features different types of ringing, crackling, and other sounds that tinnitus sufferers experience. Individual responses to such phantom sounds may vary widely.

Certain medications that affect blood flow or mood boost the risk of heatstroke

Drugs that narrow blood vessels, beta blockers that regulate blood pressure, diuretics, antidepressants, and antipsychotics can all affect the body's ability to regulate its internal body temperature, and so individuals taking these medications need to take special care in extreme heat and when exercising in hot conditions.

Eating too much salt can worsen vertigo

High salt intake can cause fluid retention in the inner ear, worsening vertigo. Slashing sodium amounts (and caffeine and alcohol consumption) are particularly recommended for those suffering from Ménière's disease to help stabilize inner ear fluid levels.

When common sounds become disturbing

Misophonia causes certain sounds to feel violating, triggering a "very visceral kind of experience" filled with extremely unpleasant emotions, including annoyance, anger, and disgust. A 2017 study found that people with misophonia have elevated activity in the brain's anterior insula—a region associated with interoception, emotional processing, and behavioral responses—when exposed to trigger sounds. Ongoing research suggests trigger sound context affects the severity and manifestation of the condition.

Scientists are reevaluating the causes of Alzheimer's beyond the amyloid hypothesis

The cause of Alzheimer's disease has been debated for decades. The amyloid cascade hypothesis—where plaques build up in the brain, triggering neurodegeneration—has long been the leading theory. But after a number of failed drug trials, researchers are beginning to reevaluate various culprits. [Untreated hearing loss is linked with dementia risk](https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext) Hearing loss does not cause dementia, but it does increase the risk of developing dementia and research suggests that people who wear hearing aids for age-related hearing loss also maintain better brain function than those who don't.

Q-tips can cause more problems than they solve

Swabbing the ear with a Q-tip can disrupt the ear wax that naturally protects the ear from dirt and bacteria. It can also tear the delicate skin of the ear drum, causing permanent hearing loss and constant discomfort that's similar to the symptoms of swimmer's ear. (Some users may encounter a paywall.)

Overuse of antibiotics gives bacteria more opportunity to evolve their defenses

The overuse and misuse of antibiotics are significant contributors to the rise of antibiotic resistant bacteria. Experts say antibiotics should only be used for specific medical problems, and patients need to be sure to take antibiotics exactly as prescribed in order to reduce the risk of antibiotic resistance.

See how antidepressants were discovered

The decadeslong journey to the three major types of antidepressants began with medications designed to treat other maladies. Watch to learn more about how attempts to treat tuberculosis and blood pressure disorders led to new insights about neural chemistry and mood.

Inflammation appears to cause specific symptoms of depression

A large analysis of existing studies published in 2021 found that systemic inflammation is associated with fatigue, appetite changes, and sleep disruption, rather than some of depression's broader symptoms including hopelessness about the future, or feeling fearful. This may suggest that inflammation influences specific symptoms of the condition, rather than the disease as a whole.

What to listen to if you want to focus

Have you ever put your headphones in, turned on your favorite playlist, and tuned out the rest of the world? That’s the power of music. It can improve your mood, reduce stress, and enhance focus. But what kind of music is best when working or studying? Check out this list for some suggestions.

Stuffy nose congestion occurs because of swelling of the inferior turbinates

These structures in the nose above the nose hairs swell and shrink constantly and are affected by head position. They can fill with blood during illness, causing the feeling of congestion, but also when a person changes position, especially when lying down. Medications can be used to shrink them, providing temporary relief.

Tannins contribute to a wine's composition

Tannins are compounds found in many different types of food, including grape skins. When consumed, they produce a noticeable drying effect in the mouth. Because of the difference in production methods, red wines typically have tannins while white wines do not.

Typhoid smells like freshly baked brown bread

Certain ailments are associated with documented scents, including diabetes, Parkinson's disease, and typhoid. The skin of people with yellow fever, for example, can smell like a "butcher shop."

Hookworm infection, though risky, may help fight certain autoimmune conditions by tamping down the immune system's inflammatory response.

Combining two cancer drugs increased the life space of mice by 30%

A study shows trametinib and rapamycin, two drugs used for cancer treatment in humans, increased mouse lifespan when used together. The medications delayed the onset of cancer and reduced chronic inflammation, results that will be explored in future research.

Tornadoes, or twisters, have been seen on every continent but Antarctica

Because tornadoes require rising warm air to form, some meteorologists have suggested that urban environments—locations where human landscape modification has introduced materials that trap thermal energy—can enhance the conditions needed for tornado formation. Tornadoes have been reported to cause ear "popping" due to drastic changes in air pressure.

Tattoo inks are largely unregulated by the FDA

With hundreds of ink manufacturers, all unregulated by the FDA, it’s hard to determine the exact ingredients in tattoo inks. Some pigments may contain carcinogenic chemicals, such as heavy metals and aromatic hydrocarbons, or even bacterial contaminants. Red ink often causes allergic reactions and may even contain lead or mercury.
