Kirk Parsley, MD, inventor of Sleep Remedy, has been a member of the American Academy of Sleep Medicine since 2006 and has served as Naval Special Warfare’s expert on Sleep Medicine. A retired Navy SEAL, he is currently a performance consultant, helping others to achieve the highest quality of life possible while realizing their health, performance, and longevity goals.
In this interview, Greg Potter, PhD talks with Dr. Parsley about the critical role sleep plays in cognitive, emotional, and physical health. They discuss the best supplements to help with sleep and some good reasons to avoid pharmaceutical sleeping pills. “Doc” Parsley shares why he recently reformulated Sleep Remedy to be even more effective, not just for falling asleep but also staying asleep at night.
