Do you have difficulty falling asleep, staying asleep, returning to sleep, or a combination thereof? If so, you may be experiencing insomnia, which is the most common sleep disorder in the United States. As many as 40 million Americans suffer from it every year. Although it can affect men and women and children of all ages, it tends to be more prevalent in women and older adults.

Acute insomnia occurs suddenly and briefly, lasting from one night to a few weeks, and is often due to a particular circumstance, such as an upcoming important or stressful event.

Chronic insomnia, on the other hand, is when you have sleep trouble falling, staying, or returning to sleep at least three nights per week for at least three months straight.

Additionally, there are two types of insomnia: primary, which means it isn’t linked to any other health condition, and secondary, in which the insomnia is a result of another condition such as asthma, depression, arthritis, cancer, heartburn, pain, medication, or substance use.
