Blame the Brain for the Hearing Loss That Comes With Aging

The reason why older people typically can’t hear very well has very little to do with the functional capabilities of their ears, Co.Exist reports. Instead, as a recent study in the Journal of Neurophysiology (freely available here) investigates, it has more to do with how the brain processes sound, and how that ability deteriorates as we age.

Researchers at the University of Maryland, College Park report that the deterioration is due to aging’s effect on the brain’s midbrain (associated with hearing as well as vision and motor control) and cortex (associated with thought and language). The study examined 17 younger adults and 15 older people with no signs of dementia. They were asked to listen to an audiobook while another narrated audiobook played in the background.

When trying to distinguish between the voices of two different speakers, the midbrains of older adults don't respond as strongly as those of younger people. The older adults' brains couldn’t encode the auditory signals as well, and they took longer to process speech, especially when there were two competing voices. The older brain appears to be less capable of picking out one sound out of many.

However, their cortex actually reconstructed the amplitude of the speech they heard in the brain with greater accuracy—an exaggerated response, which may reveal why older people need to pay more attention to process the noise of people talking. As the study's abstract notes, this response suggests "an age-related over (or inefficient) use of cognitive resources that may explain their difficulty in processing speech targets while trying to ignore interfering noise."

So the next time you encounter an older individual who is hard of hearing, don’t bother trying to speak louder. It won’t help them hear you any better. Instead, move your conversation to a place with less background noise.

Getting a full eight hours of sleep can be tough these days. If you’re having trouble catching enough Zzzs, consider giving these highly rated and recommended products a try.

1. Everlasting Comfort Pure Memory Foam Knee Pillow; $25

For side sleepers, keeping the spine, hips, and legs aligned is key to a good night’s rest—and a pain-free morning after. Everlasting Comfort’s memory foam knee pillow is ergonomically designed to fit between the knees or thighs to ensure proper alignment. One simple but game-changing feature is the removable strap, which you can fasten around one leg; this keeps the pillow in place even as you roll at night, meaning you don’t have to wake up to adjust it (or pick it up from your floor). Reviewers call the pillow “life-changing” and “the best knee pillow I’ve found.” Plus, it comes with two pairs of ear plugs.

This Letsfit model—which is rated 4.7 out of five with nearly 3500 reviews—has 14 potential sleep soundtracks, including three white noise tracks, to better block out everything from sirens to birds that chirp enthusiastically at dawn (although there’s also a birds track, if that’s your thing).

According to the National Sleep Foundation, too much light in a room when you’re trying to snooze is a recipe for sleep disaster. These understated polyester curtains from ECLIPSE block 99 percent of light and reduce noise—plus, they’ll help you save on energy costs. "Our neighbor leaves their backyard light on all night with what I can only guess is the same kind of bulb they use on a train headlight. It shines across their yard, through ours, straight at our bedroom window," one Amazon reviewer who purchased the curtains in black wrote. "These drapes block the light completely."

It’s rated 4.7 out of five stars on Amazon, with one reviewer reporting that “when it's spread out over you it just feels like a comfy, snuggly hug for your whole body … I've found it super relaxing for falling asleep the last few nights, and it looks nice on the end of the bed, too.”

Few things can disturb your slumber—and that of the ones you love—like loudly sawing logs. Philips’s Smartsleep Snoring Relief Band is designed for people who snore when they’re sleeping on their backs, and according to the company, 86 percent of people who used the band reported reduced snoring after a month. The device wraps around the torso and is equipped with a sensor that delivers vibrations if it detects you moving to sleep on your back; those vibrations stop when you roll onto your side. The next day, you can see how many hours you spent in bed, how many of those hours you spent on your back, and your response rate to the vibrations. The sensor has an algorithm that notes your response rate and tweaks the intensity of vibrations based on that. “This device works exactly as advertised,” one Amazon reviewer wrote. “I’d say it’s perfect.”

Seniors in a North Carolina Assisted Living Facility Are Looking for Pen Pals

Although coronavirus still holds many mysteries for the researchers working to understand it, one thing is certain: Older populations, particularly those in group living facilities, are at high risk of serious complications. Assisted living facilities around the country have largely shied away from allowing visitors, which means residents have little contact with anyone beyond staff.

Victorian Senior Care in North Carolina is looking to change that the old-fashioned way. They’re soliciting pen pals for their residents.

The facility, which has several locations throughout the state, has set up a program for residents looking to correspond with someone. Each person has a photo profile listing their name and interests. Enjoy video games? Then you might like exchanging letters with Robert at The Living Center of Concord. Know about farming and heavy farm equipment? Mr. Tom at The Village of Kingston is your man. Don’t mind an old rascal? Check out Leon at Montgomery Village, who likes “shag dancing” and “loves girls.”

You can find dozens more seniors who have a lot of life experience to share on the Victorian Care Center’s pen pal page. The program is already a success, with over 15,000 letters received to date. One location is even at letter capacity, as all the seniors looking for a new friend at their Phoenix Assisted Care location have a full dance card.

Other care facilities throughout the country are also hoping to match residents with pen pals. Ridgecrest Healthcare and Rehabilitation Center in Forney, Texas, has resident profiles on their Facebook page:

None of these facilities are offering email addresses, which means you’ll have to correspond like pen pals did for centuries—with pen and paper.
