It is critical that we support our circadian rhythms to enable good sleep cycles. But today we are bombarded by these wavelengths of blue and green light all day long.

In the evening when the sun is down and we should natural be setting our circadian clocks for sleep, we have interior lights, computer screens, TVs, phones and more that are bombarding our eyes with these critical blue and green wavelengths of light and interrupting our circadian clocks. If you have trouble falling asleep, adding glasses that block these wavelengths of blue and green light can be the key to naturally falling asleep better and getting better sleep.

We have written about this for a while. A few years ago in our “The 30 Day Ketogenic Cleanse” book and more recently in our book “Keto.“. But with further understanding of how blue AND green light at certain wavelengths can effect sleep, we searched for glasses that would block all the wavelengths to enable natural sleep cycles to improve.

Here are some key takeaways from the studies on the eye light receptor:

  • 446–477nm was identified as having the strongest effect on melatonin suppression. You need to make sure 100% from 446-477nm is blocked after dark
  • Polychromatic action spectra were reasonably consistent in indicating that the spectral region between 450 and 550nm provides the strongest stimulation of circadian and neuroendocrine responses. What this means is the wavelengths of light between 400-550nm should be completely blocked for optimal melatonin secretion after dark.
  • Past studies have shown that the peak wavelength sensitivity was 555nm (Rodieck, 1998) (5). Previous data (Brainard et al, 2001) (6) and those presented in the 2001 study (4) do not support this hypothesis. The results clearly demonstrate that 555nm is significantly weaker in suppressing melatonin. This is a great study for determining the optimal range of artificial light to block after dark and the study results and graph clearly suggests that the major disruption zone for melatonin is between 400-550nm with a peak between 446-477nm. It is clear we must block 100% blue and green light from 400-550nm to have optimal melatonin secretion after dark. Almost every blue light blocking pair of glasses on the market does not do this. A cross section of test results from a spectrometer have been released that show just this (7).

We searched for a company that made glasses that blocked 100% of these blue and green wavelengths. We found the company called BLUblox. They make glasses that block 100% of the blue and green wavelengths needed to naturally allow your body to produce melatonin.

When you get a good night’s rest your body has adequate time to repair and rejuvenate.

TOP 10 TIPS for QUALITY SLEEP

  1. Avoid sugar and foods high in carbohydrates, like popcorn, chips, and ice cream, especially in the evening hours. It causes low quality sleep and it stalls our metabolism. When blood sugar rises too much, it falls too low, causing you to wake up because of low blood sugar and hunger.
  2. Add in salt before bedtime. When people start the keto diet, or start to do longer fasting, sleep often suffers. One reason is because lack of sodium levels in the evening really interferes with quality sleep!
  3.  Follow a regular sleep schedule by going to bed and rising at the same time. I know I sound like a loser, but I’m usually in bed by 8:30pm and rise at 6am.
  4. Before bed do something to relax your muscles and your mind (meditation, gentle stretching, yoga or deep breathing exercises).
  5. Reduce or eliminate caffeine (chocolate has caffeine, so beware). Despite working at coffee shops since I was 15 years old, I cut out all coffee and caffeine and never felt better!
  6. Darken your bedroom with heavy drapes. We have black-out blinds.
  7. Turn the heat down. We often sleep with the windows cracked open even in the winter; I sleep the best at about 57-60 degrees.
  8. Try cold therapy before bed. I do cold therapy nightly to cool my body down to help with mitochondria health and increasing sleep.
  9. Women: Get your progesterone level tested. I often see women that can fall asleep, but wake up in the middle of the night. I have helped copious amounts of women get good sleep with natural supplements to help with hormone health.
  10. WEAR BON CHARGE blue blocking glasses! I usually put my BON CHARGE blue blocking glasses on around 5pm. Yep, 5pm! It is best to stop blocking all the blue light about 2-3 hours before bedtime to allow the body to naturally produce melatonin. With stylish blue blocking glasses you can start wearing them in the evening while still hanging out with friends. They even make a good conversation starter! You are biohacking your sleep. 🙂
