I originally passed on this book as it was written by Dave Asprey, the founder of Bulletproof coffee. I am so glad I reconsidered! The book was packed with innovative, science-backed info around maximizing our lives at every age. Asprey goes in to great detail around ways to decelerate cellular aging but what I found most fascinating was the information around light. Below are direct quotes from the book I found most thought provoking around blue light and red light. Happy reading!
* Cutting out blue light is not optional, unless you’re okay with becoming one fo the 100 million plus cases of macular degeneration I’m forecasting over the next decades.
*Excess blue light causes inflammation and mitochondrial dysfunction. Blue light is not just in your electronic devices. It’s everywhere. Most modern light sources contain unhealthy amounts of blue light and far too little of the beneficial spectrums that help balance it out. This is what I call junk light. For example, LED bulbs lack many of the suns’s natural frequencies that our bodies and brains need to function, such as infrared, red and violet light. They also emit at least five times more blue light than is emitted by sunlight. Fluorescent lights also emit substantially more blue light and less infrared light than sunlight. Shining these junk light sources into your eyes close to bedtime is like Superman taking a little soak in a kryptotnie salt bath to prepare for sleep.
Reduce Blue Light Exposure By:
Unplug or cover unnecessary electrical devices in your bedroom
Invest in blackout curtains
Switch to red bulbs at night or at least get a dimmer switch
Toss out bright white LED and compact fluorescent lights
Use blue blocker glasses
* At the same time we that we’ve removed beneficial light frequencies from much of our light worries and replaced them with far too much blue light, we’ve also begun to completely avoid UVA and UVB light which are produced by the sun and are necessary for survival. While too much UVA and UVB is damaging, so is too little. When your skin is exposed to UVB light, your body coverts vitamin D to its activated, sulfated form. In other words, sunlight makes vitamin D more available so your body can use it.
* There’s also a lot of interesting research around the benefits of being exposed to the sun’s red and near infrared frequencies before you are exposed to UV light. The red and infrared light seems to prepare the cells so they can harness the power of UV rays to produce vitamin D, while naturally protecting themselves from any UV light damage. It also helps the cells recover after UV light exposure. This chronology of light exposure makes a lot of sense, as it corresponds to our circadian rhythm. Early humans were up at dawn and spent time outdoors in the morning which allowed them to be exposed to the red and infrared light of sunrise before the sun peaked at midday. Now we are spending far more times indoors under unnatural lights. If we do get natural sun exposure, it’s often in the middle of the day, the the sun was at its’ most intense.
* It’s ironic that we avoid the sun to protect our health, while in reality adequate but not excessive sun exposure helps us live longer. The circadian rhythm, which is controlled by light, is fundamental to all life’s survival on this planet.
Things You Can Do:
Install red light, which include more of the suns’ natural frequencies
Install light sources that give off the full range of frequencies
Install dimmers or use candles starting at 8pm
Get outside in the morning for 10-20 minutes too get adequate UV light exposure
Spend time in an Infrared Sauna
