The Diverse Health Benefits of Red-Light Therapy with Justin Strahan of Joovv – EP85

 In Podcast

If something seems to good to be true, it probably is. But we may have discovered the one exception to that rule, red-light therapy. Not only do light treatments eliminate skin issues like eczema, the therapy has been proven to reduce joint pain and inflammation, stimulate muscle recovery, improve thyroid function and boost testosterone levels, just to name a few of its many health benefits.




Justin Strahan is the Cofounder and Research and Development Lead at Joovv, the premier LED light therapy device company. The Joovv product line helps you reach your health and fitness goals via red and near infrared light therapy for targeted or full-body treatment. An engineer by trade, Justin managed design and development teams in the construction industry for 16 years prior to pursuing Joovv full-time.

Today, Justin explains how his wife’s search for alternative health therapies served as the inspiration for Joovv. He discusses the specific benefits of red and near infrared wavelengths, the differences between light therapy and the infrared sauna, and the specifics of Joovv’s FDA approval and additional safety testing. Justin also covers how the Joovv’s LEDs differ from lasers and the best practices for use of the Joovv Mini. Listen in for insight around the research corroborating light therapy’s wide range of benefits—and learn about the impact of light on your overall health!
