Is Your Sleep Obstructed?

Sleep apnea is when there is a pause in breathing while asleep.  There are 3 different kinds of sleep anpea – obstructive, central and mixed.  Obstructive is when the airway has become narrow, blocked or floppy.  Central is when the brain temporarily stops sending signals to the muscles that are responsible for controlling breathing.  Mixed is a combination of the two.  This article will focus on obstructive sleep apnea (OSA), although many of the causes and treatments are similar for all kinds.

It is estimated that between 3% and 7% of the population have OSA but this number could be higher as many people do not seek treatment. Older men who are obese are more likely to have sleep apnea, but it can effect women and any age group including children.[i] Obesity is the biggest risk factor for OSA so it is projected that OSA will become more common as the population becomes bigger and bigger.

OSA can cause increased blood pressure and is associated with an increased risk of cardiovascular disease.[ii]  It is also associated with an increased risk of stroke, daytime drowsiness, motor vehicle accidents and lowered quality of life.[iii]  Rates of depression are also higher in people with OSA so it is very important to seek treatment.[iv]

Starting to exercise is the first place to begin if you have OSA.  Studies have found that OSA improved even when participants didn’t lost weight.[v]  This can have a big effect on improving overall quality of life as decreased OSA will result in a better sleep leading to more energy during the day.  Then you will be able to exercise more!  You want to do at least 150 minutes of moderate intensity exercise a week.  See my blog article on exercise for weight loss for more details.

Studies have shown that acupuncture and herbal medicine are both safe and effective treatment options for OSA.[vi] [vii]

It is also important to avoid sleeping on your back.  Purchase a pillow that encourages you to sleep on your side or you can sew a tennis ball into the back of your pyjamas to keep yourself on your side.  Avoid alcohol.  Drinking alcohol within 6 hours of sleep will worsen sleep apnea. Quit smoking.  Easier said than done, but smoking is another major risk factor for OSA.

If you think you may have OSA it is important to see your healthcare provider as even mild cases are associated with increased morbidity.[viii]  For natural treatments, contact your local naturopath and start on your path to better sleep and better health.
