The year of 2020 marks a time in which our world will forever change for many reasons. My world of offering in person classes, privates, facilitating workshops, and leading corporate yoga programs have completely shifted to the virtual world. While a part of me feels lucky to have the technology to continue to run my business, I am becoming more and more concerned about how the over use of technology is affecting our health.


In the eyes, there are light-sensitive cells in our retina called ipRGCs.  IpRGCs convey irradiance information centrally via the optic nerve to influence several functions including photoentrainment of the biological clock located in the hypothalamus, the pupillary light reflex, sleep and perhaps some aspects of vision.


For a while now we have known that shift workers and others who sleep during the day and stay awake at night are at increased risk for diabetes, cardiovascular disease, cognitive impairment, and even certain cancers.


Over the course of a day, there is a natural shift in the pattern of light that directly affects how our circadian clock is “set.” For example, when we shift towards the evening to unwind at the end of our day and get ready for sleep, the natural light is shifted toward the red end of the light spectrum. In the beginning and middle of the day, when light is brightest, it is blue-shifted. Studies have shown that this pattern of light-shifting could directly determine effect our melatonin and cortisol levels, that regulate sleep, insulin release, metabolism, and other functions.


Artificial light from technology is largely blue-shifted (computers, TVs, phones). So when we are surrounded by artificial light in the evening, it disrupts the natural light cycle can lead not only to insomnia, but also to the hormonal and metabolic disregulation that promotes obesity, diabetes, and cardiovascular disease.


When I talk to like-minded friends about this, they ask right away what they can we do to avoid the imbalance of our circadian clock. My few helpful tips (that may or may not work for you) are to make sure that we go outside in the middle of the day (I try to around 12pm – 2pm). I also recommend to try to limit your screen time at night time, at least 30 minutes or so before you go to bed, try not to be looking at your phone or watch TV in bed. Lastly, I recommend using blue-light blocking glasses when you are using screens (I know theres a lot of brands out there, I am still searching for a reliable one but currently use Gamma). While I realize that its easier said than done, if we make these small shifts in our lives now, it could lead to bigger changers for our future.
