Actress Christina Applegate discusses her battle with insomnia with People magazine, reports The Huffington Post.

Christina Applegate is certainly not alone in her sleep struggles. Insomnia is the most prevalent sleep disorder in the general U.S. population, according to the American Academy of Sleep Medicine.

Research shows approximately 33 to 50 percent of adults suffer symptoms of insomnia and approximately 10 to 15 percent of adults suffering distress or impairment because of their insomnia.

Applegate told People her sleep struggles continued after her 5-year-old daughter, Sadie Grace was born in 2011.

“When my daughter was born, I got into a three-hour feeding cycle. Now she sleeps 10 hours a night, but my body still wakes up every few hours. I’ll also be up from 2 a.m. to 6 a.m. and finally fall asleep. And then [Sadie Grace] comes in and is ready for breakfast!”

Insomnia can be short-term, late-onset, or brought on by temporary situations like stress at work, family pressures or a traumatic event. The common sleep disorder can also be a chronic condition, lasting much longer, brought on by a medical condition, medicines, substances or another sleep disorder. Or insomnia may be its own distinct disorder without a clear trigger, according to the National Heart, Lung, and Blood Institute.
