Insomnia - Description

Insomnia is a very common condition that probably affects most people at one time or another. However, it tends to occur more often in certain groups of people. For example, it is more common in women and older adults. People who are divorced, widowed, or separated seem to have the problem more often than those who are single or married.

Short-term, or transient, insomnia usually lasts no more than a few days. Long-term, or chronic, insomnia lasts for more than three weeks. Long-term insomnia is more of a problem. People who are deprived of sleep for extended periods of time are at risk to themselves and others. They are unable to concentrate normally while conducting daily activities. As a result, they are more likely to have accidents at work or while driving. They may also become moody and depressed. Chronic insomnia may also lead to immune disorders. The body's immune system fights off foreign invaders like bacteria and viruses. When a person does not get enough sleep, his or her immune system does not function properly, leaving them open to infection and disease.
