Sleep apnea means that somehow your breathing is disrupted as you are sleeping. When you breathing is disrupted, you wake up just enough to take in sufficient air to keep you from suffocating. Then you fall back asleep without ever realizing that you were awake. If your breathing is disrupted in anyway, there is help available. If you are having sleep problems, the last thing you need is a sleep area that is a problem itself.
Naps are a double edged sword.
Naps are GOOD to help snap you out of that groggy, sleep deprived feeling. Naps are BAD when too many of them during the day cause you trouble with sleeping at night. When I do take naps, I set the alarm to wake me up in 20 minutes. A 20 minute nap is enough time to refresh you. When you are in bed, do only activities that will put you to sleep.
