Sleep Problem
Sleep apnea is the condition in which people frequently stop breathing at night for a disturbingly long time. Each episode ends in a burst of snoring. Because this occurs many times a night, it can interfere significantly with the brain's oxygen supply and result in morning headaches, drowsiness, and the need for many naps during the day. Ultimately, high blood pressure, heart failure, and intellectual deterioration may supervene.

Sleeping
The term insomnia can mean:
- Trouble getting to sleep (taking more than 45 minutes to fall asleep).
- Frequent wakening with inability to fall back to sleep.
- Early morning awakening.
However, none of these are problems unless they make you feel chronically tired. If you are less sleepy at night or wake up early, but still feel rested and alert, there is little need to worry.
