Sleep problems can be caused by various factors. Although causes may differ, the end result of all sleep disorders is that the body's natural cycle of slumber and daytime wakefulness is disrupted or exaggerated.

The Rumor: When faced with a problem, 'sleeping on it' will help you make the right call
At some point or another, we’ve all had to make a difficult decision. One of the most commonly offered pieces of advice is to “sleep on it.” So, is that a good idea, or is it actually just an excuse to procrastinate?
The Verdict: Sleep really can help you make better decisions
What may seem like an impossible problem could actually have a clear solution after you get a few hours...
Short-term or acute insomnia can be caused by life stresses (such as job loss or change, death of a loved one, or moving), illness, or environmental factors, such as light, noise, or extreme temperatures.
Long-term or chronic insomnia (insomnia that occurs at least three nights a week for a month or longer) can be caused by factors such as depression, chronic stress, and pain or discomfort at night.
Other factors that can interfere with sleep include:
Genetics: Researchers have found a genetic basis for narcolepsy, a neurological disorder of sleep regulation that affects the control of sleep and wakefulness.
Night shift work: People who work at night often experience sleep disorders, because they cannot sleep when they start to feel drowsy. Their activities run contrary to their biological clocks.
