Insomnia

Insomnia is a sleep disorder that is characterized by difficulty falling and/or staying asleep. People with insomnia have one or more of the following symptoms:

  • Difficulty falling asleep
  • Waking up often during the night and having trouble going back to sleep
  • Waking up too early in the morning
  • Feeling tired upon waking

There are two types of insomnia: primary insomnia and secondary insomnia.

  • Primary insomnia: Primary insomnia means that a person is having sleep problems that are not directly associated with any other health condition or problem.
  • Secondary insomnia: Secondary insomnia means that a person is having sleep problems because of something else, such as a health condition (like asthma, depression, arthritis, cancer, or heartburn); pain; medication they are taking; or a substance they are using (like alcohol).
