Budget BioHack #1: Blue light
We now live in a unprecedented time where we are exposed to massive amounts of concentrated blue light. From our phones (the worst culprits), to tablets, LED lighting, tv's, computer monitors, and even headlights! Have you noticed how blinding some newer headlights are on vehicles?
Why is blue light so harmful? Well, it's blue per se, it's the concentration. Most of our devices are tuned with blue light to be energy efficient but unfortunately this bolus of blue light when not accompanied by other bandwidths of light (like sunlight) increases blood sugar and decreases insulin sensitivity which can lead to diabetes. It also destroys DHA, an essential component of cell membranes and a source of DC electric current in our body.
Science shows that exposure to blue light after sunset suppresses melatonin activation, delays sleep onset, and reduces REM sleep. The worst part? Even dim indoor lighting and screens can be enough to throw off your body’s internal clock.
Most people think it’s the eyes that “see” light. But your sleep system is actually controlled by something much smaller: a rare type of retinal cell called the ipRGC. These cells don’t help you see, they exist purely to tell your brain how bright it is outside. And they’re especially sensitive to blue light, which is why screen time or even ceiling lights at night can fool your brain into thinking it’s midday.
Studies show that exposure to blue light between 7–10pm delays melatonin release by up to 3 hours. The fix? Wear Night-Time Blue Light Blocking Glasses after sunset. They filter out 100% of blue (and green) wavelengths that activate ipRGCs, so your brain can finally get the message: it’s time for sleep.
That’s why I wear and make my daughter wear Night-Time Blue Light Blocking Glasses – to give our brain the darkness signal it needs, even when the world around you is still lit up.
And if you work on the computer or sit in highly artificial lighting environments, I highly recommend Day Time Computer Blue Light Blocking Glasses. This high concentration of isolated blue light could be contributing to your fatigue and migraines.
One last thing, if you don't already have a blue light blocking screen for your phone then get one here. Like I said before your phone is actually tuned at 6500K(Kelvins) which is equivalent to being midday 12pm. So if you happen to be scrolling on your phone past 7pm with no blue light mitigation then your body thinks it's high noon! This is what I and my family have on our phones. Blue Light Screen Protector.
Until next time, Be safe, Be Well. God bless :)
