In 2019, the WHO declared shift work with circadian rhythm disruption a Class 2A “probable” carcinogen – reinforcing the idea that the light you are exposed to can have dramatic effects on your health.
In this first episode of this series, Nick discusses with Andy Mant, CEO of BluBlox (now BON CHARGE), who shares the lowdown on how excessive blue light at night impacts your sleep quality, blood sugar regulation and much more.
Discussed during this episode:
- What happens to your circadian rhythm when you are exposed to blue light at night through your light bulbs or screens
- How sleep deprivation affects blood sugar regulation and insulin resistance
- The increasing amount of science linking blue light to macular degeneration
- How blue light impacts the release of melatonin at night

I am noticing focus issues after being on screen for hours. Can this be from close focusing too long or is the blue light also a play? Will you be doing any shows on what cook book has the least emf radiation. Gas burners has toxic off gas but is electric any better to induction burners? Are some brands better than others. Thank you for what you are doing
Hey Mary, induction stovetops emit very high magnetic fields. Not my favorite on an EMF standpoint.
Gas is fine, but you need very good ventilation as you’ve pointed out.
Good old electric stoves or glass stovetops are probably the easiest to manage.
Screentime itself is very unnatural for the eyes and causes eyestrain. Your eyes are designed to look at different distances over time, not stare at one object for hours.
EMFs are at play, and so is blue light. When I wear blue light blockers (yellow ones for daytime use) my focus is way better.
Thank you Nick for this. I appreciate the info and the length of the podcast which is easy to get thru and assimilate. I’m quite aware of the blue light problem & do have 2 diff inexpensive blu blockers I mostly wear at night and they do make a difference – my sleep has improved. Bc they are cheap I cannot read with them but that is not the objective. I do however read on my phone during daytime so wonder how important blue blocking is during those hrs? And do you know if changing the light (making darker or more warm on the phone) helps mitigate the blue light, or is it just a color change? My biggest problem is my bad habit of reading emails & news on my iPhone X in the morning. After doing this for an hr or two I have Symptoms I didn’t wake up with like low back pain & increased stiffness. Other than not doing this(lol) let me know if you have any suggestions on mitigating cell phone sensitivity. Thanks!
Hi Christina,
1) Suggestions to mitigate cellphone EMFs can be found at https://theemfguy.com/062/ — in the morning I look at a few news on my phone, but use an Ethernet cable, so zero EMF radiation. Doing this would help you reduce exposure a lot.
2) If you use nightshift on your iPhone it does reduce the blue light, a bit. Make sure the brightness is the lowest possible too. It’s not a replacement for blue blockers though.
3) You may want to consider using daytime blue blockers (yellow tinted) like I always do when I work at the computer, watch TV or look at my phone for more than a few minutes.
4) Blue light exposure during daytime is way less damaging for your circadian rhythm compared to doing the same thing in the evening. However, the fact remains that none of these of blue light are harmless – they emit frequencies, an intensity and other characteristics that are artificial, and likely cause oxidative stress to your body.
Nick
Can you suggest a spectrometer to measure the light? For a layperson, but with USB port for data-logging. Any place where I can learn how to use one of these meters?
My colleague Brian Hoyer uses a custom made https://www.hopoocolor.com meter. I’d look into their products. They are hard to get, but I’m sure you can arrange something if you contact the manufacturer.
