Sleep apnea (OSA) is a common sleep illness afflicting a generalized 20% of the population In Australia and New Zealand. Sleep apnea warning signs include snoring and choking, gasping or silent breathing pauses during sleep. Those with sleep apnea generally complain of feeling tired all the time regardless of how much sleep they get. In addition to being a health issue it may also affect a player’s hockey performance. Now it is clinically proven to be true.
A new study shows that obstructive sleep apnea is associated with impaired exercise capacity, which is an indicator of increased cardiovascular risk. Results show that the predicted peak oxygen uptake, a measure of aerobic physical fitness, was significantly lower in people with moderate to severe obstructive sleep apnea than in controls. Further analysis found that sleep apnea severity alone explained 16.1 percent of this variability. “We found a significant association indicating that there is likely a very strong independent relationship between obstructive sleep apnea and exercise capacity,” said lead author Dr. Jeremy Beitler, assistant clinical professor in the Division of Pulmonary and Critical Care Medicine at the University of California, San Diego. “Based on our findings, future studies are warranted to evaluate the utility of cardiopulmonary exercise testing for cardiovascular risk stratification in patients with obstructive sleep apnea.”
The AASM reports that obstructive sleep apnea (OSA) is a common sleep illness afflicting at least 25 million adults in the U.S. Sleep apnea warning signs include snoring and choking, gasping or silent breathing pauses during sleep. The National Healthy Sleep Awareness Project, which is led by the AASM and funded by the Centers for Disease Control and Prevention, urges anyone with symptoms of sleep apnea to visit http://www.stopsnoringpledge.org to pledge to “Stop the Snore” by talking to a doctor. The study involved 15 adults with moderate-to-severe obstructive sleep apnea and 19 controls with mild or no sleep apnea. All subjects were evaluated for sleep apnea during an overnight, in-lab sleep study. Cardiopulmonary exercise testing was performed on a stationary bicycle using a ramp protocol. Predicted peak oxygen uptake (VO2) was calculated as the maximum oxygen uptake in the final 20 seconds of exercise before exhaustion.
What is the cause of Sleep Apnea?
Sleep apnea is caused when your throat closes during sleep and causes you to stop breathing. Many things such as a narrow throat, large tonsils or excess tissues in your throat may cause OSA. Talk to your doctor if you think you may suffer from OSA.

How Is Sleep Apnea Treated?
Sleep apnea is treated with lifestyle changes, mouthpieces, breathing devices, and surgery. Medicines typically aren’t used to treat the condition.
The goals of treating sleep apnea are to:
- Restore regular breathing during sleep
- Relieve symptoms such as loud snoring and daytime sleepiness
Treatment may improve other medical problems linked to sleep apnea, such as high blood pressure. treatment also can reduce your risk for heart disease, stroke, and diabetes.If you have sleep apnea, talk with your doctor or sleep specialist about the treatment options that will work best for you.
Lifestyle changes and/or mouthpieces may relieve mild sleep apnea. People who have moderate or severe sleep apnea may need breathing devices or surgery. If you continue to have daytime sleepiness despite treatment, your doctor may ask whether you’re getting enough sleep. (Adults should get at least 7 to 8 hours of sleep; children and teens need more. If treatment and enough sleep don’t relieve your daytime sleepiness, your doctor will consider other treatment options.
Lifestyle Changes
If you have mild sleep apnea, some changes in daily activities or habits might be all the treatment you need.
- Avoid alcohol and medicines that make you sleepy. They make it harder for your throat to stay open while you sleep.
- Lose weight if you’re overweight or obese. Even a little weight loss can improve your symptoms.
- Sleep on your side instead of your back to help keep your throat open. You can sleep with special pillows or shirts that prevent you from sleeping on your back.
- Keep your nasal passages open at night with nasal sprays or allergy medicines, if needed. Talk with your doctor about whether these treatments might help you.
- If you smoke, quit. Talk with your doctor about programs and products that can help you quit smoking.
Mouthpieces
A mouthpiece, sometimes called an oral appliance, may help some people who have mild sleep apnea. Your doctor also may recommend a mouthpiece if you snore loudly but don’t have sleep apnea.
A dentist or orthodontist can make a custom-fit plastic mouthpiece for treating sleep apnea. (An orthodontist specializes in correcting teeth or jaw problems.) The mouthpiece will adjust your lower jaw and your tongue to help keep your airways open while you sleep.
If you use a mouthpiece, tell your doctor if you have discomfort or pain while using the device. You may need periodic office visits so your doctor can adjust your mouthpiece to fit better.
Breathing Devices
CPAP (continuous positive airway pressure) is the most common treatment for moderate to severe sleep apnea in adults. A CPAP machine uses a mask that fits over your mouth and nose, or just over your nose.
The machine gently blows air into your throat. The pressure from the air helps keep your airway open while you sleep.
Treating sleep apnea may help you stop snoring. But not snoring doesn’t mean that you no longer have sleep apnea or can stop using CPAP. Your sleep apnea will return if you stop using your CPAP machine or don’t use it correctly.
Usually, a technician will come to your home to bring the CPAP equipment. The technician will set up the CPAP machine and adjust it based on your doctor’s prescription. After the initial setup, you may need to have the CPAP adjusted from time to time for the best results.
CPAP treatment may cause side effects in some people. These side effects include a dry or stuffy nose, irritated skin on your face, dry mouth, and headaches. If your CPAP isn’t adjusted properly, you may get stomach bloating and discomfort while wearing the mask.
If you’re having trouble with CPAP side effects, work with your sleep specialist, his or her nursing staff, and the CPAP technician. Together, you can take steps to reduce the side effects.
For example, the CPAP settings or size/fit of the mask might need to be adjusted. Adding moisture to the air as it flows through the mask or using nasal spray can help relieve a dry, stuffy, or runny nose.
There are many types of CPAP machines and masks. Tell your doctor if you’re not happy with the type you’re using. He or she may suggest switching to a different type that might work better for you.
People who have severe sleep apnea symptoms generally feel much better once they begin treatment with CPAP
Surgery
Some people who have sleep apnea might benefit from surgery. The type of surgery and how well it works depend on the cause of the sleep apnea.
Surgery is done to widen breathing passages. It usually involves shrinking, stiffening, or removing excess tissue in the mouth and throat or resetting the lower jaw.
Surgery to shrink or stiffen excess tissue is done in a doctor’s office or a hospital. Shrinking tissue may involve small shots or other treatments to the tissue. You may need a series of treatments to shrink the excess tissue. To stiffen excess tissue, the doctor makes a small cut in the tissue and inserts a piece of stiff plastic.
Surgery to remove excess tissue is done in a hospital. You’re given medicine to help you sleep during the surgery. After surgery, you may have throat pain that lasts for 1 to 2 weeks.
Surgery to remove the tonsils, if they’re blocking the airway, might be helpful for some children. Your child’s doctor may suggest waiting some time to see whether these tissues shrink on their own. This is common as small children grow.
