To be diagnosed with insomnia, your sleep problems must cause a negative effect on your quality of life, such as daytime sleepiness, irritability or difficulty at work or home. The causes, symptoms and effects of insomnia vary for each individual.

Sleep specialists identify two types of insomnia:

  • Short-term insomnia lasts for a brief period, up to three months at most.
  • Chronic insomnia continues for three months or more and occurs at least three times per week.
