US News & World Report interviews sleep physicians and compiles an introductory guide for patients.
Anyone can have situational episodes of sleep problems, says Dr. R. Neal Aguillard, director of the Mid-South Pulmonary Specialists Sleep Disorders Center in Memphis, Tennessee. Oftentimes, he says, bad experiences can leave you ruminating at night – but your normal sleep eventually returns.
However, if you’ve been having sleep problems for two to three months or so, you should probably seek help, Aguillard says. Once your specific sleep disorder is diagnosed, a variety of treatment options await you.
