1. How Sleep Can Help Fight COVID.

Sleep specialists have long known that sleep and immunity are intimately connected. The coronavirus pandemic meant that the general public  became much more receptive to this message.

2. Ways to Improve Oral Appliance Outcomes.

Obstructive sleep apnea patients are becoming more aware of oral appliances as a treatment option, but professionals are still challenged by how to customize the devices optimally for specific patients. New research paves a way forward.

3. Why Early Intervention Can Make an Outsize Difference.

Identifying and treating (in some cases, curing) sleep and/or airway problems during childhood may mean not only fewer sleep problems down the line but also fewer comorbidities.

4. What Is Sleep’s Role in Memory?

Mysteries are slowly unraveling surrounding what sleep does for our brains. As researchers make breakthroughs in understanding sleep’s function in what we retain, everything from optimal test-taking to PTSD-avoidance may be within our reach.

5. Emerging Categories of Treatments.

New products and services in existing categories (such as CPAPs or insomnia drugs) are consistently popular news items. But of even greater interest are the possibilities of entirely new categories of treatments. What categories might be added to the Buyer’s Guide in 5 years? Perhaps “Movement Therapies for Insomnia” or “Sleep Apnea Prescription Drugs.”
