Trouble Sleeping? Insomnia May Be Why
Insomnia is the personal perception of inadequate or poor-quality sleep. Contrary to popular belief, insomnia cannot be simply defined by the total amount of sleep you get or how long it takes you to fall asleep. People vary dramatically in both their need for sleep and in the time they require to fall asleep. What constitutes a refreshing night's sleep for one person can be insomnia for another. In other words, insomnia is in the mind of the sleeper (or non-sleeper, as the case may be).
Insomnia can be particularly devastating because it often provokes daytime behaviors that only worsen the condition. Persons without adequate sleep may attempt to combat their fatigue and trouble concentrating by excessive caffeine intake, by tobacco smoking and by consuming unhealthy or sugar-laden foods. Insomniacs may be "too tired" to exercise and may take afternoon naps, both of which further reduce the ability to fall asleep the following night.
Insomnia is more likely to occur in females, persons over 60 years of age, and persons who have a history of depression, but anyone can be affected.
Transient, or short-term, insomnia is defined as insomnia that lasts from one night to a few weeks. Having episodes of transient insomnia between periods of normal sleep is termed intermittent insomnia. Chronic, or long-term, insomnia lasts a month or more and occurs most nights.
Short-term insomnia is common during periods of increased psychological stress. For example, just before or during a trip. Short-term insomnia is also a common side effect of certain medications such as those for colds and nasal congestion.
