Coughing, chest pain, and medication side effects are sometimes to blame for lost sleep. Other possible causes include restless legs syndrome, gastroesophageal reflux disease (GERD), and obstructive sleep apnea—a condition characterized by repeated episodes of interrupted breathing while sleeping. Following are several sleep strategies to consider.

You’ll sleep more soundly if you’re truly tired at bedtime. Exercise may help. But avoid it close to bedtime and don't drink caffeinated beverages late in the day.

Maintain a regular sleep schedule by going to bed and waking up around the same time each day, and try to skip naps during the day.

Talk to your doctor to make sure your inhalers and steroids are the right dose to get you through the night. If restless legs syndrome or GERD keep you awake, you may need medication to treat those conditions.

Sleep aids—either prescription or over-the counter—can be dangerous because they slow breathing and reduce your response to stimuli while sleeping.

If your doctor determines that low blood oxygen levels contribute to your sleep problem, supplemental oxygen may help.

Continuous positive airway pressure (CPAP) devices deliver a steady stream of air through a nsaal mask that you wear overnight. If you avoided using a CPAP device in the past because it was unwieldy, you may want to reconsider. CPAP designs have improved significantly in recent years.
