The REAL Blue Light Effect on Stress, Sleep, and Weight Loss with Corey Ghazvini, DOM

Feb 02, 2022

If you struggle with low energy, high stress, and trouble sleeping, watch this interview to learn the REAL effect blue light has on your stress, sleep, and weight loss. Losing weight is not as simple as eat less, exercise more. We know that optimizing sleep, stress, and movement can help...but an often overlooked piece of the equation is environment. That includes toxins and your light environment. 

In this interview Dr. Ghazvini explains how our overloaded blue light environment from technology is raising cortisol, blood glucose, insulin and ultimately weight. Directly contributing to disease and weight loss resistance. 

You’ll learn practical strategies to improve your circadian rhythm including morning sunlight, blue light blocking glasses (that actually work), downloads to block blue light from your computer, and many more strategies to reduce your blue light exposure.
