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.
I’ll let you in on a little secret: I snore. I’ve always snored, but I’ve only recently been able to admit it publicly.
When I was eight years old, my concerned parents took me to a specialist, who declared my adenoids unfit and scheduled an immediate surgical removal in the hopes of resolving my snoring problem. Normally, the medical team would take the tonsils at the same time, based on the theory that one bad set of vestigial organs may lead to another. Not mine. My doctor left my tonsils intact...
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.
