Hearing Loss from Group Fitness Classes: Truth or Hype

Anybody who’s health conscious will want to know the truth about hearing loss dangers from pounding music in group fitness classes.

Imagine you, the group fitness class enthusiast, are transported back in time about 60 years. Your mission is to spread the word that smoking damages the lungs.

Yeah, right. People will think you’re nuts. Cigarettes are offered to passengers on airplanes. Print ads for cigarettes say, “Just what the doctor ordered.” Ads for cigarettes are all over TV.

It took decades for the truth about smoking’s hazards to be taken seriously.

Unfortunately, this same denial continues to be playing out when it comes to the damage that thundering music in group fitness classes causes to hearing.

Attend enough fitness classes and you’ll get hearing loss.

“It is true that group fitness participants like their music loud to be motivated to move in their workouts,” says Rachel Raphael, M.A., CCC-A, an audiologist with ENT Baltimore. She’s also a certified group fitness instructor..

“The catchphrase of my popular Les Mills certifying agency (out of New Zealand) was ‘Turn It Up!’ which kind of makes me cringe knowing the potential danger in blasting our music.”

Vast Majority of Fitness Class Instructors in Denial about Hearing Loss Risk 

“As an audiologist, I have an obligation to limit the output of the music, and not ‘turn it up,’ so that I don’t cause hearing loss in the participants,” says Raphael.

“I believe there is a happy medium where the music can be loud enough without being dangerously loud.”

The music in fitness classes is louder today than it was in the 1970s, even ‘80s. It seems to be getting louder and louder. The excessive amplification of the group fitness class leader’s microphone makes the issue even worse.

Raphael says that she jokes to her class she’d be happy to fit them with hearing aids “in the near future if they insist on louder music!”

Group Fitness Classes Are Not Night Clubs or Rock Concerts

The music volume, says Raphael, “should never be in the category of rock concert loud (approximately 120 decibels), or to where people experience tinnitus (ringing in the ears; phantom ear noises) or fullness in the ears following the exposure (a sign of temporary threshold shift), like is often reported after rock concerts.”

Good hearing just as important as good cholesterol, good bone health and good muscle tone!

“Typically, the rule of thumb is sounds of 85 dB (average factory) or louder are potentially damaging to the fragile hair cells of the inner ear cochlea (length of exposure and individual susceptibility also play a big role), and people should limit their duration and/or use hearing protection in their presence.”

Performing complicated or grueling moves in a fitness class will not protect even the fittest person from hearing loss when the music is thundering.

Unlike coronary heart disease, hearing loss is NOT reversible.

Can Slamming Weights at the Gym Cause Hearing Loss?

It’s time for the big boys to admit it: Slamming and banging weights will likely damage hearing over time.

For this article on hearing loss resulting from weights being thrown, slammed and banged around at gyms, the expert source is Rachel Raphael, M.A., CCC-A, an audiologist with ENT Baltimore. 

An audiologist is an expert in hearing loss, measures people’s hearing and fits patients with hearing aids.

Raphael explains, “I never actually took a sound level meter to the smashing of weights in a weight room, but it is likely that even short durations of loud intense weights dropping, can have the same potential damage to hearing as a shotgun blast or an air bag deploying (both estimated at 140 dB).”

I’ve been lifting heavy weights for years and years, and I’ll admit, even the loudest sound of a 400 pound barbell crashing to the floor from an uncontrolled deadlift doesn’t seem as loud as a shotgun blast.

However, Raphael is pointing out that the banging and clanging of weights need not be as loud as a shotgun blast to cause hearing loss.

So how loud IS all the smashing and banging of weights at a gym?

Imagine when it really gets loud. This can be either from a number of men banging the metal plates together when loading barbells or other equipment, or from one solitary individual deliberately smashing plates or letting the weight stack on a machine slam down to get attention.

It’s NEVER an issue of exhaustion.

Some heavy lifters utilize control all the way to the end of a mammoth set, and besides, most of the exceedingly loud banging occurs when loading equipment.

Plus, many of the men who let weights crash down at the end of a set don’t even use that much weight.

Anyways, imagine the noise.

You know it’s intermittent rather than continuous like a chainsaw.

Now, imagine that it’s continuous. To me, it seems as though if continuous, the sound of banging metal upon metal weight plates, or letting very heavy barbells crash to the floor, would be at least as loud as a chainsaw only a few feet away, even louder – maybe almost as loud as firecrackers going off continuously.

With that said, Raphael further explains, “If in fact, the smashing weights are in this range for volume, it wouldn’t take much for the person at close range to suffer permanent damage, in the way of high frequency sensorineural hearing loss and/or tinnitus as a symptom secondary to the damage in the cochlea (inner ear).”

Few men who ripple with muscle and bench press 300 pounds will admit they might have hearing loss.

Now here’s a chilling fact:

When I speak to men in the gym to ask about equipment availability or have small-talk, they often ask me to repeat myself!

My speech is clear and articulate. Why aren’t they hearing me? Well, maybe because the gym is loud.

However, I can hear them just fine, even though they’re not talking particularly loud; their vocal volume is in a normal range.

Now get this: I’m able to hear them even though I have decibel-reduction ear muffs on at all times! The reduction is 29 dB, yet I can understand speech in a noisy gym.

Don’t take this as boasting. It’s my way of pointing out some very powerful anecdotal evidence that many men in gyms have hearing loss.

Perhaps for some of these men, the hearing loss stems from a loud factory job, frequent concert or ball game attendance or blasting music in their cars.

But let’s be more realistic:

Over a period of years, the amount of time that these men have spent in an environment replete with banging, clashing metal-upon-metal noise is SIGNIFICANT.

Exposure to recurring loud noise is hazardous to the nerve cells in the ears that transmit sound waves to the brain.

Repeated insults to these nerve cells will cause hearing loss. It’s a simple concept.

Ramming a 45 pound metal plate into another produces a VERY LOUD sound.

Multiply that out over the course of one workout—several times a week—52 weeks a year—over 10 years.

Banging Metal Plates at the Gym Is a Recipe for Hearing Loss

“The person who is more susceptible to damage (no way of knowing in advance) is all the more at risk, with even less intense exposures and shorter durations of exposure of any type,” says Raphael.

“I have no doubt (without any hard data to back me up) that the loud banging of metal plates against each other in the weight room falls into the category of dangerously loud.

“Most gyms and weight rooms discourage the banging or throwing of weights as a matter of good etiquette.

“When lifting weights, good ear safety is every bit as important as good technique to keep the workout safe!”

Wood Chipper Can Damage Hearing: Wear Ear Protection

I’m stunned that often, I see men without hearing protection working around wood chippers.

Wood chippers can be screaming loud, yet many workers continue to “chip” without protection for their ears. A typical wood chipper comes in at 110 decibels.

A decibel is a unit of sound volume. Working all day around 110 dBs, even if it’s not continuous, is asking for a lot of trouble.

For comparison, a chainsaw is 105 decibels. This data is from Cornell University’s Toolbox Safety Talk Hearing Conservation guidelines.

Rachel Raphael, M.A., CCC-A, an audiologist with ENT Baltimore, explains that she would “urge anyone using this or other loud construction tools, drills, saws, mowers, etc., to use hearing protection!”

SHALL IT BE THIS ?

OR THIS ?

Sometimes I DO see tree workers with industrial ear muffs while around the wood chipper.

And I’m sure there are those who wear custom-made ear plugs which an observer would not be able to see.

But many don’t think about damage to their ears from these machines and hence, go without protection.

“Young people think they’re not vulnerable to hearing loss (because young ears and hair cells usually bounce back initially from loud exposure), but over time, the temporary damage turns into permanent damage, and for now, scientists have not been able to regenerate hair cell growth in human cochleas (only in some lower forms of lab animals),” explains Raphael.

“I tell my patients to take care of the hearing they have control over, because soon enough, we will all ultimately suffer the effects of hearing loss that comes with old age.

“And although digital hearing aids are smaller and more sophisticated than ever, they will never be as good as our own healthy normal hearing ears.”

To guard against hearing loss when around a wood chipper, drug store earplugs may not be effective enough.

You may be able to find a good pair from an online retailer, but you’ll need to try different kinds.

If you don’t succeed, you can always use the muffs or custom made earplugs.

Can a Deep Vein Thrombosis Be Permanent?

Warning: A DVT can leave permanent effects. You want to do everything possible to avoid this very serious (and highly avoidable) condition.

A vascular surgeon responds to the question: Can a deep vein thrombosis become permanent?

Athletic people or fitness enthusiasts are NOT immune to the development of a deep vein thrombosis.

Even a very fit woman, who’s on birth control and fails to move her legs around much during a long airline flight can end up with a blood clot in her leg.

Can a deep vein thrombosis become permanent?

“Yes it can…which can then lead to the post thrombotic syndrome,” begins Paul Lucas, MD, surgeon with the Vascular Center and director of the Vascular Laboratory at Mercy Hospital in Baltimore.

“These are signs and symptoms that may occur as a long-term complication of DVTs.  This includes chronic pain, swelling, itching, skin discoloration (stasis dermatitis), ulceration, heaviness and even varicose veins.”

Treatment for Acute Deep Vein Thrombosis

“Thrombolysis, the chemical/or mechanical means to break down a clot, can be offered if the DVT is considered acute,” says Dr. Lucas. 

“Usually, this can be done within the first two weeks of the DVT formation.”

However, continues Dr. Lucas, not all patients are candidates for thrombolysis. An example would be a pregnant woman developing a DVT.

The thrombolytic agent has the potential side effect to cause sudden internal bleeding.

Catheter-targeted thrombolysis involves radiation exposure.

“These would be potentially harmful to the fetus and the mother,” says Dr. Lucas. 

“After the window of opportunity to lyse the thrombus has been passed, the clot would be considered permanent,” in the case of a pregnant patient.

“Our bodies also have a means to break down a clot, called the fibrinolytic system, and sometimes this can lead to recanalization of veins, or even completely remove the clot.”

Dr. Lucas leads a team of vascular surgeons and technologists who specialize in the diagnosis and treatment of patients with diseased blood vessels.

Can Fish Oil and Garlic Supplements Lower DVT Risk?

Find out what a DVT expert says about fish oil and garlic supplements as preventive measures.

A deep vein thrombosis is a pretty common condition in the general population, but there are those individuals who are at particularly high risk.

And those are people with multiple risk factors. Any one of the following risk factors, when combined with one, and especially two, of any of the others, puts a person at a noteworthy risk for a DVT.

  • Smoker
  • Obese
  • Sedentary lifestyle, no regular exercise, excessive daily sitting
  • Use of birth control pills
  • Frequent air traveler, long flights, few walking breaks while on the plane
  • Long distance truck driver who takes few walking breaks
  • Recent joint replacement surgery
  • Recent abdominal surgery
  • Excessive bed rest for some other condition
  • Pregnancy

The thicker that blood is, the more likely it will clot under the right circumstances, such as the risk factors above.

Aspirin thins out the blood, but it comes with side effects, namely stomach upset. It can also cause internal bleeding.

Fish Oil, Garlic and DVT Risk

Fish oil and garlic are natural blood thinners and anti-inflammatory agents.

Can they help lower the risk of a deep vein thrombosis?

“Yes, fish oil can have a protective effect [against deep vein thrombosis], as omega-3 fatty acids are known to reduce inflammation throughout the body,” says Paul Lucas, MD, surgeon with the Vascular Center and director of the Vascular Laboratory at Mercy Hospital in Baltimore.

Inflammation Is a Precursor to DVT

“Inflammation to damaged cells lining veins can lead to thrombus formation,” says Dr. Lucas.

“Garlic is an effective blood thinner and may reduce DVT risk.  These do convey some risk reduction, but small.”

Popping fish oil and garlic supplements doesn’t give you a pass for sitting in your truck’s cabin for five hours straight, or refusing to get up and walk around a little bit while on a long airline flight. Or to continue smoking.

Rather, fish oil and garlic supplements are an adjunct to an overall program that’s designed to prevent your blood from becoming thick and sticky, leading to a dangerous clot.

Fish oil contains omega-3 fatty acids that help reduce blood clotting by making platelets less likely to stick together.

Garlic has compounds that may help lower blood pressure and improve blood flow.

When used alongside a healthy diet, consistent cardio and resistance exercise, and other lifestyle changes such as keeping hydrated, these supplements can support cardiovascular health and reduce the risk of clot-related complications. 

Fish oil supplements come in capsules, liquid and softgels.

Capsules are a popular choice due to their convenience and ease of swallowing, while softgels offer a similar benefit but are often easier to digest.

Liquid fish oil provides the option for those who prefer not to take pills, though it has a strong taste that some may find unpleasant.

Additionally, fish oil supplements can be found in flavored versions to mask the fishy taste.

Garlic supplements also come in various forms. The most common are garlic capsules or tablets, which contain powdered garlic or garlic extract and are designed to reduce the strong odor associated with fresh garlic.

Garlic oil supplements are another option, providing garlic’s benefits in a liquid form, usually in softgel capsules.

Additionally, there are aged garlic extracts available, which are often marketed as having fewer odor issues and potentially enhanced health benefits. 

Any form of fish oil or garlic will help lower the risk of DVT.

Prolonged Desk Work Can Cause DVT: Tips on Prevention

Excessive desk work certainly can increase one’s risk of DVT, says Dr. Paul Lucas.

The human machine was not designed to spend all day sitting at a desk.

Unfortunately, that’s what many men and women must do to earn a living.

However, many people — once they get home from the sedentary workplace — continue with the excessive sitting.

“Excessive desk work certainly can increase one’s risk of DVT, as sitting for prolonged periods leads to stasis that poses a risk for thrombus development,” says Paul Lucas, MD, surgeon with the Vascular Center and director of the Vascular Laboratory at Mercy Hospital in Baltimore.

Various studies indeed show that excessive sitting increases the risk of developing a blood clot in the leg.

“It is important stretch your legs, get up and walk for even a few minutes when doing this type of work,” says Dr. Lucas.

Prolonged sitting slows down blood flow, creating conditions that can be ripe for DVT formation.

“For every 30 minutes of sitting you should do these things to reduce that risk,” says Dr. Lucas.

“So, push back your seat and stretch those legs.  This is also important in air travel and prolonged car or train rides.”

In addition, stay well-hydrated! You may want to fill a pitcher with water in the morning, and then drink from that. This way it’ll be easier to track your water intake.

Remembering to get up every 30 minutes or so to exercise the legs can be cumbersome for people who are deeply absorbed in deadline work at a desk. 

They should look into the idea of a treadmill desk. Many different makes and models are on the market.

If your employer won’t allow this, then have one set up at your house — either before the TV or for your computer.

If you have other risk factors for a DVT, such as smoking, obesity, lack of an exercise program or use of birth control pills, you really need to make a concerted effort to offset excessive sitting from desk work.

Can Chronic Stress Cause a DVT?

A vascular surgeon is asked if chronic stress can actually trigger a deep vein thrombosis.

“There is no real objective data on an association of chronic stress and DVT risk that I am aware of,” says Paul Lucas, MD, surgeon with the Vascular Center and director of the Vascular Laboratory at Mercy Hospital in Baltimore.

However, Dr. Lucas says this: “Chronic stress can lead to elevation in blood pressure. This can result in damage to vessels leading to a setup for atherosclerosis, plaque buildup … and lead to heart attacks and strokes.”

Ongoing anxiety, persistently being “wound up” and “stressed out,” puts the body in a fight or flee mode.

To prepare for what the body thinks is an imminent fight or escape from danger, various physiological changes take place, including thickening of the blood to protect against bleeding to death. This proved handy for primitive man.

For modern man, this protective response can backfire; chronically thickened blood (chronic stress from job, finances, traffic jams, etc.) is more prone to clotting up.

Chronic stress can lead to behaviors that put a person at high risk of a DVT.

  • Overeating leading to obesity
  • Excessive inertia, too much bed rest, prolonged cramped seating on a long airline flight or long vehicle drive
  • Lack of exercise, sedentary lifestyle
  • Smoking

Can Compression Stockings Cause a DVT to Break Off?

A doctor answers the question if compression socks or stockings can trigger dislodging of a DVT.

Compression socks or stockings are well-known to people who have a medical condition that causes fluid retention in their legs.

This may be liver disease, kidney disease, or much more commonly, chronic heart failure.

The compression socks help push the backed-up fluid upward. Plus, they can reduce the discomfort that’s caused by the edema.

A person who has a medical condition that would cause enough fluid back-flow in the legs to necessitate the need for compression stockings is also a person who has a DVT risk that’s higher than that of the average population.

Complicating the issue is that if both of the patient’s legs are quite swollen at any given time, the swelling that’s caused by a deep vein thrombosis will not be as obvious as it would be in a normal leg.

And not all deep vein thromboses turn a leg red, hot or cause a calf cramp.

“Contrary to what most people believe, movement in general does not trigger a DVT to dislodge,” says Paul Lucas, MD, surgeon with the Vascular Center and director of the Vascular Laboratory at Mercy Hospital in Baltimore.

“Dislodgment of a free-floating clot is more dangerous and prone to embolization at rest or with movement.”

Compression Garments

Dr. Lucas explains, “In the presence of DVT and unilateral leg swelling, mild compression garments can be worn to ease the swelling and offer support. 

“They don’t squeeze the clot causing it to propagate or embolize.”

Lowering DVT Risk when You Have a Serious Medical Condition

One of the fastest ways to cut DVT risk is to quit smoking.

Another quick way is to take up exercise. If your legs hurt all the time due to your medical condition, then have a seat and do upper body strength training.

Drink six to eight cups of water a day and never sit for more than an hour nonstop.

If you’re obese, it’s time to start a safe weight loss plan.

Having a condition that warrants the use of compression socks does not give you a pass on taking measures to lower your risk of a DVT.

Does Psoriatic Arthritis Increase DVT Risk?

Find out what a doctor says about rheumatic disease’s relation to a deep vein thrombosis.

Psoriatic arthritis is an autoimmune disease that has no cure — only treatments — and for some patients, the flare-ups are resistant to treatments.

One thing that they might worry about is if psoriatic arthritis raises the risk of developing a deep vein thrombosis.

“Rheumatic disease doesn’t cause DVT,” begins Paul Lucas, MD, surgeon with the Vascular Center and director of the Vascular Laboratory at Mercy Hospital in Baltimore.

He continues, “It does, however, pose a risk for the development of DVT.  In fact, a three-fold increase researchers have found.”

Risk Factors for a DVT in no Particular Order

  • Birth control pills
  • Smoking
  • Pregnancy
  • Sedentary lifestyle, no regular exercise
  • Long airplane flights or vehicular travel with little movement in the legs
  • Obesity
  • Recent joint replacement or abdominal surgery
  • Genetic clotting disorder
  • Psoriatic arthritis

Dr. Lucas explains, “The biologic etiology of the elevated risk is a bit tricky.  There isn’t anything definitive noted in the literature I looked up.

“There is speculation that there are increases and decreases in various liver proteins and factors that may convey the increased risk.”

What does this mean if you have psoriatic (or rheumatoid) arthritis?

If you have any of the aforementioned risk factors, see which ones that you can modify as much as possible.

Some of them are quite easy to modify, such as standing up and walking around for several minutes, at least once an hour, on a long airline flight or while at your workplace desk.

If you smoke, quit. Yes, just quit already.

Start a plan to lose weight if you’re obese. If you smoke and are also obese, at least you can instantly eliminate one of these DVT risk factors.

If you don’t exercise, it’s time to start. Psoriatic arthritis does not contraindicate exercise.

Finally, drink at least six, eight-ounce glasses of water a day, as dehydration can elevate the risk of a DVT in vulnerable individuals.

Swelling from DVT vs. Joint Replacement Fluid Retention

Is there a way to tell the difference, without imaging, between DVT swelling and post-surgical edema or fluid retention from a joint replacement surgery?

When a joint replacement patient views their affected limb for the first time free of any bandage or wrapping, the patient is bound to be in for a shock at how swollen the limb is.

If the patient knows some basic facts about deep vein thrombosis, they may start wondering if what they’re viewing is swelling from such a blood clot.

Joint replacement surgery is a major risk factor for a deep vein thrombosis.

But a knee or hip replacement will also cause par-for-the-course swelling.

“Swelling after joint replacement can be due to lymphedema, or reactive swelling due to the surgery itself,” says Paul Lucas, MD, surgeon with the Vascular Center and director of the Vascular Laboratory at Mercy Hospital in Baltimore.

“Lymphedema can be caused by over-hydration during surgery, or by disruption or scarring of lymphatic channels near and around the soft tissues in the area of the surgery,” explains Dr. Lucas.

“Swelling may or may not be associated with a DVT.  You cannot discern between them; you have to get an ultrasound to be sure that a DVT isn’t being missed.”

Your orthopedic surgeon as well as any other kind of doctor such as a vascular specialist simply cannot tell whether your swelling is from a DVT or the surgery itself.

However, the presence of other symptoms can definitely arouse high suspicion for a blood clot.

Based on other symptoms, your doctor will order an ultrasound of the limb.

Symptoms Suspicious for a DVT

  • Unusual redness of the leg
  • Excessive warmth in a part of the leg
  • Cramping or pain in the calf, even though this area was not operated on.
  • Sudden difficulty breathing (can mean a DVT dislodged and traveled to the lung).
  • Sudden chest pain (another symptom of a blood clot traveling to the lung).

If you’re scheduled for joint replacement surgery, expect to see a lot of swelling the first time you see your bare skin. The puffiness can last for several weeks.
