 Insomnia is divided into:
- Transient (short-term) Insomnia is the inability to sleep well and feel refreshed in the morning of the next day over a period, lasting fewer than four weeks.
This type of insomnia is usually caused by stress or excitement. Almost everybody has had this experience before important events or changes of the daily routine such as taking an exam, going on holiday in a foreign country, or after an argument with a close relative or friend. Children, for example, may turn and toss just before starting of school in the fall, or before sporting competitions or important exams. Adults may sleep badly before an important business meeting. People tend to have this type of insomnia when they are away from home, especially if they have passed through time zones. High physical activity before bedtime also leads to insomnia. So this type of insomnia is usually linked to a higher stress level or the inability to calm down before bedtime and stop worrying.
- Intermittent (on and off) Insomnia is a short term type of insomnia that occurs from time to time and each time lasts less than a week or two.
This type of insomnia may not require treatment. As a rule intermittent insomnia occurs due to a passing change in the sleep/wake schedule, as with jet lag, and the biological clock will often turn back to habitual on its own. Sometimes the use of short-acting sleeping pills may improve sleep and next day vivacity. But it may cause some side effects.
- Chronic (on-going) Insomnia lasts more than one month.
It can be caused by account for behavioral, medical or psychiatric problems such as depression. It is the rarest and most serious type of insomnia. Approximately 15% of Americans suffer from it.
To strive with chronic insomnia you must first define its symptoms. Then visit your doctor, he will prescribe you necessary treatment. Taking anti-depressant medication can help improve sleep.
In its turn chronic insomnia may be divided into:
- Primary insomnia. This kind of chronic insomnia is not concerned with any other health problem.
- Secondary insomnia. It is usually caused by a medical condition (asthma, cancer, arthritis some others), drugs, stress or a mental health problem (depression), or a poor sleep environment (too much light or noise).
