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:

i) Difficulty falling asleep, ii) Waking up often during the night and having trouble going back to sleep, iii) Waking up too early in the morning, iv)Feeling tired upon waking.

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

1) Primary insomnia: Primary insomnia means that a person is having sleep problems that are not directly associated with any other health condition or problem.

2) 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).

Acute -vs- Chronic Insomnia

Insomnia also varies in how long it lasts and how often it occurs. It can be short-term (acute insomnia) or can last a long time (chronic insomnia). It can also come and go, with periods of time when a person has no sleep problems. Acute insomnia can last from one night to a few weeks. Insomnia is called chronic when a person has insomnia at least three nights a week for three months or longer.
