While the statement “sleep apnea may negatively impact sleep” seems obvious what is not so obvious is that there are different levels of sleep apnea, and some people may have slight sleep apnea without even knowing, especially when they snore a lot.  Sleep apnea is when the person stops breathing momentarily during sleep. The way to check for sleep apnea is to do a study in a sleep lab.

Article on sleepapnea.org writes that …

“… most people who have sleep apnea don’t know it …”

Sleep apnea treatment includes the use of positive airway pressure machines (PAP machines), avoid sleeping on back, and “nighttime dental devices that push the lower jaw or the tongue forward”.

You may also want to try an anti-snore strap which works by keeping your mouth closed in the correct position and preventing the tongue from blocking airway.  But this tend to work for mouth snorer rather than nose snorers.  [reference]

If you suspect that you might have sleep apnea have it checked out at a sleep lab, or try sleeping on your side.  In the past before PAP machines were invented, people taped a tennis ball to the back of their pajamas so that they would not sleep on their backs which tends to improves sleep apnea symptoms.

Alternatively you my try sleeping in a reclining bed where your upper torso is recline upwards slightly.
