Insomnia is a sleep disorder that affects people of all ages
without gender or age distinction. There are also different types of insomniacs – there are some who just can’t sleep even if it is night and all lights are off, some who simply keep getting up during the night and some who find it tough to go back to sleep once they get up really early in the morning. Whatever the reason, the result is that the person suffers due to lack of sufficient sleep and the body and mind become lethargic. This is because they are missing out on nature’s method of recharging and revitalizing the body.
Although there are several different degrees of insomnia, three types of insomnia have been clearly identified: transient, acute, and chronic.
- Transient insomnia lasts from days to weeks. It can be caused by another disorder, by changes in the sleep environment, by the timing of sleep, severe depression, or by stress. Its consequences - sleepiness and impaired psychomotor
performance - are similar to those of sleep deprivation.
- Acute insomnia is the inability to consistently sleep well
for a period of between three weeks to six months.
- Chronic insomnia lasts for years at a time. It can be caused by another disorder, or it can be a primary disorder. Its effects can vary according to its causes. They might include sleepiness, muscular fatigue, hallucinations, and/or mental fatigue; but people with chronic insomnia often show increased alertness. Some people that live with this disorder see things as though they were happening in slow motion,
whereas moving objects seem to blend together. Can cause double vision.
