If you have someone who knows what you sound like when you sleep, consider yourself thankful. The “easy” warning signs of sleep apnea are far easier to pick out if there’s someone on the outside looking in while you’re trying to get sleep.
The easiest of the easy symptoms is snoring. Snoring is:
[a] [h]arsh buzzing noise produced by a sleeper, produced primarily with inspiration due to vibration of the soft palate and pillars of oropharyngeal inlet …
Basically, breathing is partially obstructed by tissue in the throat area, and as the air goes by, that tissue vibrates and makes noise. The vibration is the (very fast) opening and closing of the airway.
Snoring by itself does not imply the existence of sleep apnea, but it indicates the presence of obstruction that can develop into obstructive sleep apnea.
If you don’t have someone regularly listening to you sleep, then try getting a sound recorder. (My wife did this, and I don’t really think that I believed her until she played the recording for me.
