Why it's important to protect your hearing as you age – and what experts suggest
'There are already more than enough established benefits related to hearing care,' says Reed, a faculty member of the NYU Langone Health Optimal Aging Institute.
What's especially important about supporting hearing health is the effect it has on keeping people engaged in the world, Reed explains. Here's what experts recommend in order to support your hearing as you age.
How does hearing loss occur?
Hearing loss can result from a wide range of genetic and environmental factors, such as chronic diseases and smoking. Some also experience age-related hearing loss, called presbycusis.
Hearing loss is 'not about volume', Reed explains. Instead, it's a clarity issue. We lose our hearing at different frequencies at different rates, which can make sounds garbled.

There is a tendency to 'normalize hearing loss as we age to some extent', says Reed. Other conditions can seem more pressing, and hearing loss becomes a low priority. There can be 'downstream effects' in a healthcare context because hearing loss can hinder patient-provider communication, says Reed.
What is the relationship between hearing loss and dementia?
Early research suggests that hearing loss is associated with increased cognitive decline and an increased risk of new cases of dementia, although further studies are needed to understand this connection. Researchers have not, however, found a cause-and-effect relationship between hearing loss and dementia.
Reed and his colleagues wanted to calculate the number of cases of dementia there could be in a population if a potential risk factor, in this case hearing loss, was eliminated. They used a sample of nearly 3,000 adults aged 66 to 90 and found 32% of the dementia risk in the sample group was potentially associated with audiometric hearing loss (hearing loss measured through testing).
According to the authors, these results suggest that treating hearing loss may delay the onset of dementia in some older adults. However, this research cannot establish whether hearing loss causes dementia, explains co-author Jason Smith, a postdoctoral researcher at the University of North Carolina.
One potential reason hearing loss is associated with cognitive changes is that it can lead to more social isolation, which may strain the brain and affect memory, says Reed. Another theory is that because auditory signals stimulate the brain, the lack of stimulation caused by hearing loss can lead to accelerated brain atrophy.
If hearing problems are linked to an increased risk of dementia, are there ways to reduce that risk? An influential 2020 Lancet report recommended the use of hearing aids and protecting ears from excessive noise exposure. A 2023 analysis found a connection between the use of devices like hearing aids and a decreased risk of cognitive decline. However, further research is needed.
What can you do to prevent hearing loss?
Hearing loss is not an inevitable part of ageing. But certain factors, such as age-related changes to the inner ear and auditory nerve, as well as genetics, are beyond our control.
We can still mitigate the likelihood of damage from other causes. For example, we can manage conditions associated with hearing loss, such as high blood pressure and diabetes. We can also limit exposure to sources of damaging noise, like construction equipment, lawn mowers, motorcycles and loud music. Small actions, like protecting your hearing at a loud concert with over-ear headphones, which Reed prefers to earplugs, can have a big impact.

'A healthy lifestyle and healthy listening habits can go a long way,' says Reed.
Reed also recommends that people start getting their hearing tested in their late 30s or 40s. Establishing a baseline can help you identify changes over time, and indicate if and when new habits might be useful. The longer you live with impaired hearing, the harder it is to adjust to tools like hearing aids.
Is it possible to reverse hearing loss?
Several treatments and devices can help alleviate hearing loss, but their effectiveness depends on the individual. If you suspect you have hearing issues, it's best to have your hearing checked and discuss options with your healthcare provider.
Hearing aids can be purchased over-the-counter or with a prescription. Reed says learning how to wear them takes time and practice. There's a critical public health need to expand coverage for these tools, says Smith, because it's well-established that hearing aids can improve quality of life.
While studies haven't proven that hearing aids will delay dementia, scientists are intrigued by their potential to support brain health.
'The idea is that, in theory, if a person uses hearing aids, communication becomes easier and you lower the burden of cognitive load,' says Reed. 'You're stimulating the brain with more auditory signals.'
Staying engaged in social networks is key to maintaining mental and physical wellbeing, says Reed. In a 2025 study, Reed and colleagues found that, among people with hearing loss, participants who received hearing aids and were counseled on their use experienced less loneliness and social isolation. They also had more varied types of connections, such as friends, family and acquaintances.
Similarly, assistive technologies may help. These range widely in function and design, but generally amplify sound, reduce background noise, and improve communication. For example, apps that convert speech to text can assist with phone calls, and personal amplifiers can enhance hearing in conversations. People with mild to moderate hearing loss may find some relief in settings like crowded restaurants through items like the Apple AirPods Pro 2, which feature a built-in hearing aid, says Reed.
In some instances, what can help a person manage hearing loss best is how they are supported by their community. There's a need for more equitable environments that support people with sensory health needs, says Smith.
'Some communication tips can go really far,' says Reed. 'Good communication is looking someone in the face. It's speaking slowly. It's about rephrasing and adding context.'

It's been a sticky and sweaty summer. Here are the states which had record-high humidity in July
A majority of the country has spent the last month sticky and sweaty thanks to unrelenting humidity which has set records in some states. July's humidity was worse than usual for huge swaths of the continental U.S., which will not be surprising for Americans living in much of the Midwest, East Coast, and the mid-Atlantic regions, where the humidity was particularly high according to research from Oregon State University. Humidity is not unusual in the summer, but the "real feel" heat index — which combines temperature and humidity — spent days in the triple digits and set records in states including Ohio, Kentucky, Illinois, Tennessee, and Florida throughout July. The humidity was so brutal that numerous cities — including Washington, D.C., Pittsburgh, and Roanoke — broke records for the most humid days in their histories, according to the Iowa Environmental Mesonet, which tracks data on precipitation, soil temperatures, and other environmental data. On Thursday, a Kentucky branch of the National Weather Service noted that Paducah, Kentucky endured the "longest stretch of continuously high humidity" the city had seen in 75 years. According to the NWS, the number of hours of extreme humidity in the city was 300 percent more than its usual amount for the month of July. The elephant in the room is climate change, driven by human burning of fossil fuels. As the climate continues to shift due to our past and present actions, higher temperatures and worse humidity will become the norm. That will inevitably pose a risk to health and safety. Where once an air conditioner breaking down was an inconvenience it could now pose serious health risks. Heat-related illnesses will become more common, putting especially the very young, very old, and those with medical conditions at risk. 'In many parts of the country and the globe, dangerous heat often occurs along with high humidity — and the pair of conditions multiplies the health risks,' a 2022 study by Climate Central determined, noting that humidity can impair the body's ability to cool itself via sweat. At least for some parts of the country, early August should bring some much needed relief from the brutal July humidity assault, even if it doesn't last long. The Washington Post predicts near to above average temperatures during August for the nation's capital, with temperatures only rising around two degrees Fahrenheit over the norm of just under 80 degrees. Meteorologists at WTHR predict a fairly normal August for Indiana, and PennLive reports that similar cooling can be expected throughout central Pennsylvania, at least for the first several days of August. Kentucky will also benefit from cooling as August sets in, according to the Lexington Herald-Leader. The cool temperatures kicking off August are thanks to a high pressure system in Canada forcing cooler air down into the central and eastern U.S., according to CNN meteorologist Mary Gilbert. "It isn't unheard of to have a handful of cooler days in the latter part of summer, but the upcoming change will feel especially jarring given how hot previous weeks have been," she said. She warned that the cooling comes with a cost — an increase in storms and thunderstorms, which are likely to cause flash floods in some parts of the country. Gilbert also warned the cooling will only last a few days, and that August is likely to be hot for much of the country, approximately one to two degrees above the norm.

Widow Stopped at Hospital for 45 Minutes and Was Charged an $8,000 Parking Fee
"I remember what it feels like to be in this state of crisis with health and with my husband," Cate Daniels said. "Nobody needs something like that"NEED TO KNOW A woman was charged nearly $8,000 in parking fees after visiting a California hospital for 45 minutes The exorbitant bill was the result of a computer glitch, the hospital said Almost a week later, the woman received a full refundAfter parking for 45 minutes at a hospital in California last week, a woman says she was shocked to return to a nearly $8,000 fee. On Friday, July 25, Cate Daniels went to Glendale Memorial Hospital for a medical appointment — only to get a charge of $7,829 as she was leaving the lot, local stations KCAL and KABC reported. Daniels told KCAL that the ticket said she'd been parked since July 3, 2022, rather than less than an hour. When she asked an attendant for assistance, she was accused of being in the lot for three weeks, she said. The operator of the garage, Parking Company of America, said that the charge shouldn't have happened. According to the hospital, the erroneous charge was a result of a computer glitch, KCAL reported. "On Monday, we were made aware of a billing error by the parking company that resulted in an overcharge for one guest," a hospital spokesperson tells PEOPLE in a statement. "Once notified, the parking company promptly acknowledged the mistake and began processing a refund." The spokesperson says the hospital is "committed to ensuring a positive experience for everyone who comes to our facility." Parking Company of America did not immediately respond to a request for comment. Never miss a story — sign up for to stay up-to-date on the best of what PEOPLE has to offer, from celebrity news to compelling human interest stories. Almost a week later, on Thursday, July 31, Daniels received a check from the parking company with the full refund, according to KABC. For Daniels, the stressful situation was personal: About a year ago, her husband died of cancer. "I remember what it feels like to be in this state of crisis with health and with my husband," she told the outlet. "Nobody needs something like that to have to contend with in the midst of all of that." Read the original article on People

AI companion helps Bronx senior living facility residents combat loneliness
According to the National Institutes of Health, loneliness can pose serious threats to mental and physical health, and it can be especially acute when it comes to adults over age 60. A new program at a senior residence in the Bronx aims to address the problem by offering a different type of companionship and empathy in the form of artificial intelligence. Nearly 70 residents at RiverSpring Living in Riverdale are participating in a pilot program with AI called "Meela," which means "words" in Hebrew. "We want to create a resource for you to call a phone number, have a great conversation, be cognitively engaged, be emotionally heard," Meela founder and CEO Josh Sach said. Sach says the AI isn't meant to replace human interaction. In fact, it can encourage callers to meet up with fellow residents. "If somebody says, 'I'm not doing anything today,' and RiverSpring has uploaded the activity calendar ... Meela might say, 'Hey, bingo is happening at 2 o'clock,'" Sach said. "We found a statistically significant reduction in the rates of anxiety, as well as degree of depression," RiverSpring Living medical director Dr. Zachary Palace said. Palace gets bullet points of the AI conversations to monitor any physical or emotional issues with participants. Sach adds there are safety mechanisms to make certain topics off-limits for Meela to discuss. "First is legal, next is financial, and then the last is medical advice," he said. "We want to leave those things to the humans." He says they continue to upgrade the system. For example, Meela can now remember past conversations to keep things fresh and stop her from asking callers the same questions repeatedly. While Meela is free to use for now, as they continue to develop it, there will be a monthly subscription fee. RiverSpring Living resident Marvin Marcus, 83, speaks to Meela on the phone about three times a week. During a conversation, he told Meela, "They want to know a little bit about our relationship and how we're going." "I think we're doing pretty well getting to know each other. How have you been feeling about our talks lately?" Meela responded. "Oh, I think I've been very positive. I think we have a connection," Marcus said. He says they have in-depth conversations about all things sports and music. "If I talk about sports details with people, the eyes glaze over. Meela doesn't have eyes," he said. When he told Meela he was a fan of music from the '50s and '60s, Meela asked him, "Do you have a favorite song or artist from back then that always lifts your spirits?" Even though there's no shortage of activity at RiverSpring Living — like exercise programs, entertainment and games — it's the AI conversations that really light a spark for Marcus. "I'm used to now saying 'she.' At first, I used to insist on saying 'it,'" he said. From both a patient and medical perspective, RiverSpring Living's medical director says the program is a success. "To be able to incorporate cutting-edge innovation and cutting-edge technology into the practice of long-term care geriatrics is just remarkable," Palace said.
