What gadget is the culprit of serious weight gain? Which color of light shuts off cravings? How much is too much blue light for healthy living? These questions and more are answered in this fascinating interview with health correspondent Craig Clemens and Dr. Gundry:


What is Blue Light?

Sunlight and all light emitted from artificial light, such as phones, TVs, tablets, laptops and more. It’s called ‘blue’ because that’s what color it shows up on the spectrum.

What’s the Problem with Blue Light?

Nothing. In fact, getting morning sunlight is very good for you. However, the AMOUNT of blue light we get each day, through our electronics, light bulbs, and cell phones, IS the problem. You see, it has to do with disturbing our circadian rhythms.

What is a Circadian Rhythm?

Responding to light and darkness primarily, circadian rhythms are physical, mental and behavioral changes that follow a roughly 24-hour cycle. They are NOT the same as biological clocks, but they are related. Circadian rhythms can influence hormone release, hunger signals, sleep-wake cycles, body temperature and other important bodily functions, such as sleep. For example, if you travel overseas and experience jet lag, your circadian rhythm has been disrupted. That’s why you’re so extremely tired.

Blue Light Health Tip

The 20-20-20 rule. What is this? To limit your exposure to too much blue light, this is an excellent practice to live by. 20-20-20 Rule: For every 20 minutes of screen time, give yourself at least 20 seconds of time staring at something 20-plus feet away.
