Insomnia

From Simple English Wikipedia, the free encyclopedia

Insomnia is when people cannot sleep for long or short periods. A person with this problem is called an insomniac. Insomnia can mean a problem with getting to sleep or a problem with staying asleep. Insomnia is a symptom and not a disease or illness.[1]

There are at least three different types of insomnia:[source?]

  1. Transient Insomnia: from one night to a few weeks
  2. Acute Insomnia: from a few weeks to about six months
  3. Chronic Insomnia: years at a time

There are many causes of insomnia, but the cause might not be known in some people. Some causes are:[source?]

  • As people get older, their sleep patterns change. They will sleep shorter periods of time, but more often. Younger people usually sleep longer. This is normal

Substance abuse

  • Some insomnia issues are caused by stimulant drugs, such as amphetamine, cocaine and nicotine. Coffee stimulates the body, and people tend to drink quite a lot of it when they are at work. If they drink too much of it, they will have problems falling asleep in the evening. The same is true for tea, colas, or any other drink with caffeine in it
  • Some substances, like alcohol can have a bad effect. It can be very hard to sleep after drinking a lot of alcohol. The world may spin and there can be an urge to vomit as soon the person closes their eyes. Drugs can also have this effect, even some "sleeping" pills.

Mental illnesses

Infectious diseases

  • A very rare disease called fatal familial insomnia prevents some people from falling asleep. In this disease, a person can no longer sleep and after a while will die from being so tired. It is caused by a protein similar to the one that causes mad cow disease which is a very bad disease that comes from eating contaminated meat

Treatments

[change | change source]

There are drugs available that can help treat the different kinds of insomnia. In some cases, there are also certain herbs that can help. A third way that seems to help is a type of therapy that aims at changing the behaviour of those affected.[source?]
