By Rachael Rettner, Senior Writer | June 21, 2017 02:36pm ET
Insomnia is a sleep disorder characterized by difficulties falling or staying asleep, even though people have the chance for adequate sleep.
The condition can be short term (acute), lasting days or weeks, or long term (chronic), lasting for a month or more. Acute insomnia is often caused by stressful events, such as a death in the family, said Dr. Ulysses Magalang, director of the Sleep Disorders Program at The Ohio State University Wexner Medical Center, while chronic insomnia often has a secondary cause, such as another medical or psychiatric problem.
