A mysterious hum is reportedly plaguing the residents of Cincinnati, keeping people up at night and even disturbing them psychologically.

Residents of the Northside, Clifton and Camp Washington neighborhoods have been reporting the disturbances since December. The noises are said to be louder and more noticeable at night.

“We were hearing this siren-like quality noise — whirring, oscillating, going up and down,” said Clifton resident Shaun Herold, who contacted local news outlet WKRC about the noises.

“My son came up to me and said, ‘Dad, the tornado sirens are going off,’” Herold said. “Usually, it starts at about 10 p.m. It can go till 3 a.m., 4 a.m. But it’s quite unpredictable.”

“It kind of stresses me out ’cause I don’t know what it is. It’s kind of scary,” added his son, Elijah Herold.

Herold said he spent one entire night tracking how many times he heard the noise going on and off. The duration of the noises can vary from a few seconds to several minutes.

“I feel like it’s definitely like a foreign sound,” Northside’s Brendan Marcum told the news outlet. “Some nights it would be a little louder, some nights it would be a little quieter.”

“It kind of stresses me out because I don’t know what it is, and it’s kind of scary,” added another resident.

Hundreds of Cincinnati residents have shared their theories about potential sources of the sound on social media, ranging from biblical to supernatural.

On Reddit, other users blamed the recycling plant. “My favorite theory is River Metals Recycling,” one person wrote, claiming that the plant moved neighborhoods when the original location “wouldn’t put up with the noise from its metal shredder any longer.”

Others suspect the noise is coming from a failing turbocharger on a diesel train engine at the nearby CSX Queensgate, a major freight rail yard in Cincinnati. 

While the yard routinely generates loud, mechanical sounds, residents say they’ve never heard anything like this before.

WKRC reported that an anonymous source sent recordings of the locomotive, claiming it to be the source of the sound. However, a spokesperson for CSX told the news station that he “has not heard a noise like that on our property” and suggested it could be coming from another location.

He added that any equipment requiring maintenance is “handled through established operating and mechanical protocols.”

“We just hope to get to the bottom of it, figure out what it is, and if it’s, you know, a temporary thing or not,” Herold told the news outlet. “And hopefully the community can rally if it’s not temporary, because it’s really impacting us.”

Pilates may have a reputation for being “girly,” but a new social media trend is crushing the assumption that it’s easy.

Male athletes and “gym bros” are being humbled by the challenge of Pilates and sculpt — workouts that are typically dominated by women.

Viral videos show men wincing, clenching and shaking their way through classes, both on mats and on strengthening machines called reformers.

DIABETES PREVENTION LINKED TO SPECIFIC TYPE OF EXERCISE, STUDY SHOWS

Melania Antuchas, a Florida-based hot Pilates and sculpt instructor, jumped in on the trend, posting videos of private classes with men that have received millions of views.

In an interview with Fox News Digital, Antuchas, who teaches a 50-minute signature class combining strength training and mat Pilates, said that athletic men find the class surprisingly difficult due to their training history.

“We target the tiny muscle fibers, so it’s the muscles that you don’t use in the gym,” she said. “We’re using those big quads in the gym, we’re using heavy weights, but with just your body weight and heel raises and a band and the layering, that is the true challenge. They’re not used to challenging their balance, their mobility, their instability.”

“After I taught that first initial class for all men, every single one of them was asking for the next one because of how much it challenged them,” Antuchas added.

OLDER ADULTS SHOULD TARGET THESE MUSCLES WHEN STRENGTH-TRAINING, SAYS FITNESS PRO

After recently hosting the men of the Raleigh Rugby Club, Raleigh Pilates in North Carolina posted a video where the men appear to struggle through sets of leg lifts, lunges, shoulder presses, abs and stretches on the reformer.

Studio owner Rae Matthews noted that Pilates challenges “stronger people” differently, as athletes and weightlifters typically focus on “big global muscles,” while Pilates asks them to “slow down, stabilize and control movement through full range of motion.” 

“A lot of people are surprised because the exercises look small, but they feel really intense because the work is coming from deep stabilizers rather than momentum or brute force,” she told Fox News Digital.

What is Pilates?

Pilates was originally developed by Joseph Pilates in the 1920s to help rehabilitate injured soldiers and ballet dancers, according to Brookelyn Suddell, director of group fitness strategy and development at Crunch Fitness in New York. 

The method aimed to put muscles under controlled tension to build strength, flexibility and mobility, which is the “foundation for effective movement,” she told Fox News Digital.

Today, Pilates has incorporated more equipment, sculpt techniques for strength training, and heated settings, Antuchas noted.

“It’s a slow and controlled, non-stop, low-impact workout,” she said. “It’s about precision, it’s about control, it’s about core strength.”

Suddell added that Pilates builds a “special kind” of balanced and functional strength, working the stabilizers around each joint.

“That means your whole body is working in harmony, from your core to your limbs,” she said. “Even our Crunch CEO Jim Rowley — a Marine vet, lifelong lifter and all-around powerhouse — credits Pilates with skyrocketing his core strength and mobility.”

The experts agreed that men can benefit from the exercise just as much as women, as the practice can improve their overall gym performance, athletic pursuits, posture and longevity.

“I think the key to getting more men involved is reframing Pilates as intelligent strength training and injury prevention, not a soft workout,” Matthews said.

Words of caution

The primary reason that most people seek strength training and Pilates is to help with lower back pain, according to Antuchas.

The trainer warned that no one should feel pain during a Pilates and sculpt workout, and that modifications should be made as needed, particularly when there is strain in the neck or lower back.

Antuchas, who teaches all ages ranging from 18 to 70+, said her workouts are intentionally challenging without requiring extra equipment, as the foundational movements are demanding enough on their own.

Those new to Pilates should consult a doctor before starting to make sure it is appropriate for them.

“People should be mindful if they have recent injuries or surgeries; chronic back or neck pain; hip, shoulder, knee limitations; or limited spinal mobility,” Suddell advised.

Matthews agreed that those with acute injuries, recent surgeries, osteoporosis or pregnancy should work with “well-trained, educated instructors who understand modifications.”

“When Pilates is taught thoughtfully, it’s actually one of the safest and most supportive forms of movement available, but expertise matters so much.”

America’s heart health is improving in one key way, but a newly defined syndrome is raising alarms.

The findings come from the American Heart Association (AHA), which reported improvements in life expectancy and fewer heart attacks and strokes compared to 2023.

New to this year’s report is a focus on cardiovascular-kidney-metabolic (CKM) syndrome, a framework that examines interconnected risks tied to heart disease, kidney disease, diabetes and obesity.

HEART STUDY FLAGS DANGEROUS RHYTHM RISK FOR ENDURANCE ATHLETES OVER 50

The AHA estimates that nearly 90% of U.S. adults have at least one component of CKM syndrome.

While fewer Americans are dying from cardiovascular events, experts warn the prevalence of these risk factors could drive future disease if left unaddressed.

The data show the impact is not evenly distributed across age groups.

“We see a mixed report with some good news and some concerning news,” Dr. Bradley Serwer, an interventional cardiologist and chief medical officer at VitalSolution, told Fox News Digital.

Stroke deaths increased among certain age groups, including an 8.3% rise among adults ages 25 to 34 and an 18.2% increase among people over age 85, according to the AHA.

The data also showed increases in high blood pressure, diabetes and obesity among children and adolescents ages 2 to 19.

Serwer said the rise in stroke deaths among younger adults is particularly concerning because it reflects long-term risk that can build silently over time.

He noted prevention strategies aimed at lowering cardiovascular risk.

The AHA promotes a comprehensive prevention strategy known as “Life’s Essential 8,” which focuses on eight modifiable components of cardiovascular health, Serwer explained.

The eight elements include a healthy diet, participation in physical activity, avoidance of nicotine, healthy sleep, healthy weight, and healthy levels of blood lipids, blood glucose and blood pressure.

He noted that improving those factors could prevent up to 40% of annual all-cause and cardiovascular deaths among adults.

“It is not good enough to sit back and celebrate a reduction in heart attacks and strokes,” Serwer said. “We have to look aggressively at the data regarding our youth and target ways to combat childhood obesity, high blood pressure and metabolic syndromes which will manifest as cardiovascular disease down the road.”
