Insomnia can have a significant impact on everyday life. Whether you have trouble falling asleep or staying asleep, it can affect your overall health. Relationships and work productivity can also suffer. If you have insomnia, your doctor can help you find out what kind you have. Primary insomnia is its own disorder. It isn’t a symptom of another condition. Insomnia can either last only a few days or weeks (acute) or be long-term (chronic).
