Sleep apnea may be quietly changing your body in an unexpected way, study finds
NEWYou can now listen to Fox News articles!
Researchers in Israel have discovered a difference in muscle structure in those with obstructive sleep apnea (OSA).
According to a new study published in the journal Sleep and Breathing, people with OSA tend to have a higher muscle mass index, reflecting greater area relative to height, as well as lower density.
This means people with OSA may look like they have more muscle, but that muscle tends to be less dense and potentially less functional.
POPULAR SLEEP POSITIONS COULD BE DAMAGING YOUR NERVES, ACCORDING TO EXPERTS
The researchers gathered data from 209 adults in an overnight sleep study who underwent chest or abdominal CT scans, according to a press release.
Compared with a control group, the researchers found that people with OSA were older, more often male and heavier on average. They were also more likely to have hypertension, cardiovascular disease and poorer oxygen levels during sleep.

The findings showed a significant link between OSA and higher muscle mass index. However, lower muscle density was more strongly associated with age and weight than with OSA.
Worse sleep apnea severity was linked with lower skeletal muscle density (SMD) and higher skeletal muscle index (SMI), indicating larger but less dense muscle.

Higher BMI was strongly linked with lower SMD and higher SMI, while older age was strongly linked with lower SMD.
Individuals over 60 years old and those with a BMI over 30 had much stronger links to lower muscle density than OSA alone, according to the research.
“These findings highlight that OSA is much more than a nighttime breathing disorder.”
Dr. Wendy Troxel, a Utah-based licensed clinical psychologist and senior behavioral scientist at RAND, simplified the main study findings in an interview with Fox News Digital.
“Individuals with OSA may have more muscle mass, but that muscle may be less healthy because it contains more fat, which can impair strength and metabolic function,” said Troxel, who was not involved in the study.

“This pattern overlaps with sarcopenia, a clinical condition where muscle becomes weaker and less efficient, even if muscle size doesn’t dramatically decline.”
Troxel pointed out an “important” association between OSA severity and muscle quality, which was “modest compared to known risk factors, including age and body mass.”

“[This indicates] that OSA may be one marker within a broader profile of metabolic risk,” she said.
“Clinically, these findings highlight that OSA is much more than a nighttime breathing disorder. It may signal underlying metabolic dysfunction affecting multiple systems, including muscle health.”

In an interview with Fox News Digital, study co-author Ariel Tarasiuk, professor at the department of physiology and cell biology at Israel’s Ben-Gurion University of the Negev, shared his thoughts on the “paradoxical” findings.
“Age and obesity appeared to have a stronger influence on muscle health than sleep apnea itself,” he said. “This suggests that while sleep apnea may play a role, it is unlikely to be the primary factor driving these changes.”

Patients should be aware that sleep apnea is not just about snoring or poor sleep, Tarasiuk said, as it can affect overall health, including muscle function.
“Getting properly diagnosed and treated matters,” he said. “CPAP therapy can make a real difference in improving breathing and sleep quality, but it’s only part of the picture.”

“Maintaining a healthy weight and staying physically active are equally important for muscle health and for reducing the severity of sleep apnea,” he went on. “In short, treating sleep apnea is about protecting long-term health, not just getting a better night’s sleep.”

Tarasiuk reminded clinicians that larger muscles don’t always mean healthier, as some muscles may be infiltrated with fat, which may reduce their strength and performance.
“This highlights the importance of looking beyond muscle size alone,” he said. “Routine imaging, such as CT scans performed for other reasons, can sometimes provide additional insight into muscle quality.”

“Overall, the findings point toward a more holistic approach: treating the airway while also focusing on weight, physical activity and metabolic health.”
“CPAP therapy can make a real difference in improving breathing and sleep quality, but it’s only part of the picture.”
The study findings may not apply to all populations, as it was conducted at a single center, according to Tarasiuk.
The researchers also did not have access to information on lifestyle factors like physical activity, diet, smoking or alcohol use, factors that can influence muscle health.

“Looking ahead, larger studies across multiple centers will help confirm these findings and provide a broader picture,” Tarasiuk added.
“Future research will also focus more on outcomes that matter in real life, such as how patients respond to treatments like CPAP, and on understanding how muscle changes develop over time in people with sleep apnea.”

New details surrounding Sen. Lindsey Graham’s sudden death have drawn attention to a cardiovascular emergency that can become fatal within minutes.
A statement released by Graham’s office on Sunday cited preliminary findings from the District of Columbia’s Office of the Chief Medical Examiner, identifying the cause of death as an aortic dissection due to arteriosclerotic cardiovascular disease.
Authorities said Graham, 71, was transported to George Washington University Hospital, where he was pronounced dead at 10:23 p.m. Saturday. An autopsy was completed Sunday.

“The death certificate will be PENDING until all the toxicological and microscopic testing are finalized, and at that point the death certificate will be updated to reflect the cause of death and appropriately classify the manner of death,” the statement said.
Fox News Digital reached out to Graham’s office requesting comment.

What is an aortic dissection?
An aortic dissection is a life-threatening medical emergency in which a tear develops in the inner layer of the aorta — the body’s largest artery, according to Mayo Clinic.
“It occurs when the layers of the aorta come apart and the inner one tears,” Fox News senior medical analyst Dr. Marc Siegel, who did not treat Graham, told Fox News Digital.
YOUR RESTING HEART RATE COULD REVEAL MORE ABOUT YOUR HEALTH THAN YOU THINK, DOCTORS SAY
Blood rushes through the tear and causes the layers of the aortic wall to separate, which can disrupt blood flow to vital organs or lead to a fatal rupture if not treated immediately.
“It can come on in minutes or days and may be hard to recognize,” added Siegel, noting that while dissections can evolve over time, symptoms often appear suddenly.

Dr. Kenneth Perry, an emergency physician based in South Carolina, said the best way to visualize the condition is to think of the aorta as a hose.
“The wall of the hose has multiple layers to it, and if the layers separate, the water can no longer pass down the regular opening in the tube,” Perry, who also was not involved in Graham’s care, told Fox News Digital. “Often, this starts as a very small tear that keeps progressing because of the water pressure.”

“The same thing is happening in the aorta,” he went on. “The small tear in the wall of the aorta continues to progress, usually from severely elevated blood pressure.”
As the tear continues past the smaller arteries coming from the aorta, blood can no longer flow from the heart to the other organs.

“This causes the organs that need that blood to die from lack of oxygen,” Perry said. “The only way to survive such a diagnosis is very early identification and strict blood pressure control with emergent operative management.”
Aortic dissection is relatively rare, affecting an estimated three to four people per 100,000 each year, according to Cleveland Clinic.
What causes an aortic dissection?
In Graham’s case, the preliminary findings cited arteriosclerotic cardiovascular disease. This condition is most commonly associated with atherosclerosis, in which plaque builds up inside the arteries, causing them to harden and narrow.
Over time, this process can weaken the wall of the aorta, increasing the risk of an aortic dissection.
“It can come on in minutes or days and may be hard to recognize.”
High-risk groups
Arteriosclerotic cardiovascular disease can develop over time and is driven by several factors, according to the American Heart Association and Mayo Clinic.
Some of the groups at highest risk include the following.
- People with uncontrolled high blood pressure (hypertension), which places constant stress on the aortic wall
- Older adults, particularly those in their 60s and 70s
- Men, who are diagnosed more often than women
- People with atherosclerosis (hardening of the arteries) or other cardiovascular disease
- Those with an aortic aneurysm, which weakens the wall of the aorta
- People born with certain heart defects, such as a bicuspid aortic valve
- Those with inherited connective tissue disorders, including Marfan syndrome, Loeys-Dietz syndrome and vascular Ehlers-Danlos syndrome
- Smokers and people with longstanding high cholesterol, both of which contribute to artery damage
- People with diabetes and obesity
- Those who are physically inactive and/or eat an unhealthy diet

“Graham’s father had a cardiac arrest, and if it was from a dissection, it would increase the risk,” Siegel noted.
Warning signs you should never ignore
Symptoms of an aortic dissection can come on suddenly and often mimic those of a heart attack or stroke, experts say.
Anyone experiencing any of the below warning signs should call 911 for immediate emergency medical care, according to Siegel and other health experts.

- Sudden, severe chest or upper back pain, often described as tearing, ripping or stabbing, which may spread to the neck or back
- Shortness of breath
- Sudden, severe abdominal pain
- Loss of consciousness (fainting)
- Stroke-like symptoms, such as sudden vision changes, difficulty speaking, weakness or numbness on one side of the body
- Leg pain or difficulty walking

“Aortic dissection is one of the diseases that emergency physicians think of often when someone presents with chest pain — specifically pain described as a tearing sensation, with elevated blood pressure,” Perry told Fox News Digital.
“We often describe the aortic dissection patient as appearing to have a ‘kidney stone of the chest,’ — meaning they have severe pain and cannot get comfortable, similar to kidney stone patients.”
Diagnosis and treatment
Early diagnosis and treatment greatly improve the chances of survival for those who have suffered an aortic dissection.
Doctors typically diagnose an aortic dissection using imaging tests, including a CT scan, transesophageal echocardiogram (ultrasound), magnetic resonance angiography (MRI-based scan) and chest X-ray, per Mayo Clinic.

The condition requires immediate medical treatment, which will depend on which part of the aorta is affected.
Type A dissections involve the ascending (upper) aorta near the heart, which typically require emergency surgery.
According to the American Heart Association, an untreated acute aortic dissection is one of the deadliest cardiovascular emergencies. (iStock)
Type B dissections affect the descending (lower) aorta farther from the heart, according to Mayo Clinic. These may be treated with medications to lower blood pressure and heart rate, although some may also require surgery or a stent.
Those who survive the event will generally need lifelong blood pressure management and regular imaging to monitor the aorta, per the above source.

“This condition has a high mortality rate,” Siegel said.
According to the American Heart Association, an untreated acute aortic dissection is one of the deadliest cardiovascular emergencies.
“We often describe the aortic dissection patient as appearing to have a ‘kidney stone of the chest.’”
For untreated dissections involving the ascending aorta, the risk of death increases by approximately 1% to 2% for every hour treatment is delayed after symptoms begin, according to the American College of Cardiology and the American Heart Association.
Without treatment, more than half of people with a Type A aortic dissection die within one month. About 20% of Type A patients will die in the hospital, compared to 10% for treated Type B dissections.
Can it be prevented?
While not all aortic dissections can be prevented, people can reduce their risk by controlling certain lifestyle factors.
“You need to make sure your blood pressure is well-controlled, your cholesterol is low and that you are seen regularly by a doctor,” Siegel advised.
Smokers should kick the habit, he said, as they are at a highly increased risk.

Maintaining a healthy weight and following treatment plans for underlying heart or vascular conditions can also reduce the risk, according to Mayo Clinic.
People with a family history of aortic disease or inherited connective tissue disorders should discuss screening with their healthcare provider, doctors advise.

A terminally ill man who chose to provide for his kids over spending money on a wedding has finally tied the knot with his fiancé – 20 years after he first proposed to her.
Dean Pennell, 63, met his partner Kay Beaman, 62, through their children 24 years ago in Basildon, Essex.
The couple held off on wedding plans in order to provide for their 10 children.
THE BEST TIME TO TALK TO YOUR PARENTS ABOUT SENIOR CARE — BEFORE IT’S TOO LATE
But after being told he had just weeks to live, Pennell — who has terminal cancer — finally married Beaman on June 18 at Colchester Hospital in Essex, England, news agency SWNS reported.
The new wife said, “I am absolutely elated. We have waited a long time, and it’s so special to be able to celebrate our marriage here, with our families.”

This story discusses suicide. If you or someone you know is having thoughts of suicide, please contact the National Suicide Prevention Lifeline at 988 or 1-800-273-TALK (8255).
A 30-year-old man has been asking people he doesn’t know to sit with him in pubs across the country ever since December of last year, as part of what he calls his “Empty Chairs” campaign.
Dean Perryman came up with the idea after his best friend, Rob Clancy, tragically died by suicide at age 29 just a month earlier.
Wanting to make sure nobody else ever felt alone — even perfect strangers — Perryman started heading out to restaurants and pubs wearing a bright orange hoodie to make his presence obvious to anyone choosing to chat with him.

Just a few weeks ago, he held his program’s 1,000th meet-up in Leigh-on-Sea, Essex, featuring about 12 attendees — and said he’s proud of how far it has come.
“It has been such an incredible experience. I am loving every second of it still,” the resident of Stratford in East London told news agency SWNS.

“When I started, it came from such a place of sadness — and to see how this simple idea has been able to help so many people has been really nice,” he said. “I have been able to meet and connect with so many new people and learn about them. It gives people an opportunity to speak openly if they need it.”

Perryman works for team-building game company Chicken Rush. He used social media, he said, to create interest in the “Empty Chair” idea, he said.
The events started in London and Essex before the founder began recruiting volunteers to host them across the U.K. — and the rest of the world as well.
Events have since been planned in Manchester, Bedford, Cambridge, Skegness, Gloucester, Leeds, York, Wrexham, and more.

It has also branched out to other countries, including Colombia, Spain, the United Arab Emirates and Australia.
He said lots of people actually return to the events, especially in smaller rural towns, as people create and build friendships that last long afterward.

Perryman, who has attended 61 himself, said his favorite part of the events is seeing men open up about their troubles, as he feels they need a safe space to do so.
“Some people come because they really want someone to listen to what they have to say,” he said. “Others come because they have the capacity to be there for someone else. Everyone shares their own story, but it stays at the table.”
“No matter who you are, there is a place for you.”
He said the groups have “talked about the difficulty of living in a big city and feeling isolated, but nothing is off the table — we’ve spoken about everything and anything. To give people a place that they can go when they need to talk is incredible.”

Perryman said he has about 200 more events already lined up — and said he has no plans to stop scheduling them, SWNS reported.
He said there is no pattern in terms of who shows up. Usually, it’s a diverse group of people.

“Every Empty Chairs event you go to, you are going to meet people of different walks of life,” he said. “It is so powerful to show that, no matter who you are, there is a place for you. We have everyone — men, women, young, old. There really isn’t a barrier to entry for this. Whoever needs the space is welcome to come.”

He also said, “A lot of people come because they’re feeling lonely in a new area, or they want to make new friends.”
He said he hopes that his Empty Chairs campaign can be a lasting legacy for his best friend, Rob — someone he believes needed a similar space.

“He was the kindest, sweetest guy you could ever hope to meet,” said Perryman. “Like a lot of men, he wasn’t the biggest sharer. He was very much the life and soul of anywhere you went, but he wasn’t someone who would be the first to open up about it if he was feeling some type of way.”
“To now be in a position where Empty Chairs looks like it could be a legacy for Rob is amazing,” Perryman added.
