If you're being treated for sleep apnea, chance are you wear a C-PAP machine at night, wear a dental appliance, or have had surgery. Because treatments for sleep apnea are often uncomfortable, many people go untreated. Sleep apnea can cause a range of health problems, including heart attack, stroke, and diabetes, and cause daytime drowsiness as well.

A new, less cumbersome device to treat sleep apnea is currently being studied, and is showing promising results. When 11 people with mild to moderate problems wore a nasal cannula (a thin tube with prongs, typically used to deliver oxygen) that sent warm, moist air into their upper airways, breathing pauses and night awakenings were cut dramatically. Further studies are underway to find out if this more comfortable method may be useful in treating the condition.
