The Sleep Is A Skill Podcast 219: Dr. Raleigh Duncan, Founder and CEO, Clearlight: The Sleep-Sauna Connection—Heat Therapy Wellness Stacks For Deep Sleep
Dr. Raleigh Duncan is widely recognized for his expertise in infrared therapy, as one of the most significant contributors to technologies for healing the human body, and as a leader in advancing the industry over the past three decades. Dr. Duncan is a Board-Certified Doctor of Chiropractic and started Clearlight more than 28 years ago. Today, Clearlight is the industry leader in infrared saunas and a pioneer in innovative health and wellness solutions. The Berkeley-based wellness company designs, manufactures, and distributes infrared saunas and other complementary healing devices worldwide.
Dr. Duncan is widely considered one of the early pioneers in infrared sauna technologies and has patents or patents-pending for much of the technology Clearlight uses. For example, Clearlight was the first company to develop patented Carbon/Ceramic infrared heaters capable of delivering a deeper, more penetrating infrared wavelength, while also offering the lowest EMF (electromagnetic fields) and EF (extremely low frequency) available on the market. Clearlight’s proprietary True Wave™ far infrared and full spectrum infrared sauna heaters were designed, tested, and approved by Dr. Duncan.
Dr. Duncan has continued to demonstrate a history of serving the health, wellness, and fitness industries. His vast experience includes designing systems to help heal the body, envisioning and creating health products from inception to execution, including all phases of manufacturing and quality control. Dr. Duncan is driven by a strong desire and proven track record of taking care of consumers’ concerns and consistently meeting their needs.
Before founding the company, Dr. Duncan spent 25 years implementing computer-controlled machinery for many manufacturing facilities in the US. Dr. Duncan obtained his Bachelor of Science degree from Excelsior College and his doctorate from Life West Chiropractic College. In addition to his certification as a Doctor of Chiropractic, he is trained in CranioSacral, Network Chiropractic, and Lymphatic Massage.
Dr. Duncan is also an accomplished musician. His LP, Falling Away, debuted in the fall of 2024, underscoring Clearlight’s longstanding commitment to music, which continues to help fuel growth in the company’s wellness solutions. He splits his time between Berkeley, CA, Mendocino, CA, and Chelsea, NY.
