Technology-based Aid for better sleep like white noise machines, sleep tracking apps, and blue light-blocking glasses have also proven helpful for many. Cognitive Behavioral Therapy for Insomnia (CBT-I) is a non-drug approach that focuses on identifying and changing thoughts and behaviors that affect sleep. Whether natural, behavioral, or medical, finding the right sleep aid often requires trial and error—but the benefits of better rest, including improved mood, concentration, and overall health, make it well worth the effort.
