Primary vs Secondary Insomnia

Before talking about causes of insomnia, you need to understand that there are two types of insomnia:

  • Primary insomnia
  • Secondary insomnia

Adding to this is that there are two modes of insomnia as well, which concerns how long insomnia lasts:

Secondary insomnia means that you have insomnia as a direct result or symptom of something else, such as a health condition, medication, pain, substance abuse, etc. For example, depression can be an underlying cause for insomnia.

Primary insomnia is the opposite of secondary insomnia, and means that your trouble sleeping is not directly related to some other underlying issue.

Like anything, terms are usually much neater than real life. In real life, try to establish whether or not there is a cause for your insomnia can be difficult and full of uncertainty.

Acute vs Chronic Insomnia

In addition to understanding the two types of insomnia, you should also be aware that that there are two expressions of insomnia:

  • Acute insomnia
  • Chronic insomnia

Acute insomnia is short-term, such as dealing with insomnia for up to a month.

Chronic insomnia is symptomatic, long term insomnia, which is defined as insomnia at least three nights per week for a month or more

So in total you have 4 expressions of insomnia:

  • Secondary/acute insomnia – temporary insomnia in response to a temporary illness, stress, etc.
  • Primary/acute insomnia – temporary insomnia for no discernable reason
  • Secondary/chronic insomnia – chronic insomnia in response to (usually) chronic life problem such as pain, long term illness, etc.
  • Primary/chronic insomnia – chronic insomnia with no discernable cause

With these in mind, here are common causes of insomnia.
