WHAT IS INSOMNIA?
Insomnia can be defined as a difficulty to fall asleep or stay asleep, and can manifest itself in different ways, such as difficulty to fall asleep, waking up frequently at night or waking up early in the morning. It is estimated that a majority of the population has insomnia occasionally or sporadically a few times throughout their life. The clinical criteria most used when determining whether a person may be suffering from insomnia are: spend more than 30 minutes to fall asleep and has a total duration of sleep with less than 6 hours per night. Moreover, insomnia can also be classified according to its cause or extension in time.
If an insomnia problem is not due to medical reasons, or chemical (drug treatment), it is considered a primary insomnia. When the cause of insomnia is a symptom of a disease, or a side effect of a product or problem, it is called secondary insomnia.
Regarding the duration of the feeling of insomnia, it can be classified into three distinct categories:
- Temporary Insomnia: Is the most common, is short-lived and usually lasting less than a week. Is mainly primary and usually it occurs in situations of stress or trauma.
- Short duration Insomnia: Is a type of insomnia that can take up to a month duration and has varied causes, but predominantly cases of primary insomnia.
- Chronic Insomnia: Can exceed more than one month and usually are cases of secondary insomnia with major problems associated, caused by lack of sleep.
