Causes, incidence, and risk factors
Primary insomnia refers to insomnia that is not caused by any known physical or mental condition.
Signs and tests
Your health care provider will do a physical exam and ask you questions about your current medications, drug use, and medical history. Usually, these are the only methods needed to diagnose insomnia.
The following tips can help improve sleep. This is called sleep hygiene.
You should be able to sleep if you practice good sleep hygiene. See a doctor if you have chronic insomnia that does not improve.
