“Finally, a resource that treats light therapy with the scientific rigor it deserves.”—Dr. Gabrielle Lyon, author of the New York Times bestseller Forever Strong and The Forever Strong Playbook

Light has the power to heal your body and optimize your health. There are over six thousand peer-reviewed scientific studies showing the proven health benefits of red and near-infrared light therapy, also known as photobiomodulation (the science of using light to modulate biology). In The Ultimate Guide to Red Light Therapy, Ari Whitten, MS, cuts through all of the confusion around this complex topic. He explores the science behind this therapy and reveals how to harness its power to improve your health, your body, and your life.

You’ll discover how to

• combat skin aging, wrinkles, and cellulite to look years younger
• accelerate wound and injury healing, reduce pain, and improve joint health
• enhance fat loss and improve overall metabolic health and hormonal health
• support mitochondrial health, overcome fatigue, and improve energy levels
• improve physical performance, amplify the benefits of exercise (increase strength, endurance, and muscle mass), and accelerate exercise recovery
• enhance cognitive function and trigger neuroprotective mechanisms for brain health
• activate systemic anti-aging mechanisms like growth factors and stem cells that enhance cellular regeneration
• fight chronic inflammation, combat hair loss, and improve immune function

But knowing the benefits isn’t enough—you need to know exactly how to get them.

The Ultimate Guide to Red Light Therapy provides critical information on how to achieve the best results—determining the proper dose for every type of treatment, avoiding common mistakes that can undermine your results, and identifying devices that are worth buying while steering clear of those that are underpowered, overpriced, or ineffective.

Optimal light exposure habits are as essential to good health as good nutrition. Red light therapy is one of the biggest health breakthroughs in recent years. It’s time to start using this powerful tool. The Ultimate Guide to Red Light Therapy is your complete road map to transformation through the power of light.
