"Junk Light" The High Fructose Corn Syrup for Your Eyes

If you are aware of the latest studies on health and how the macro-environment affects our micro-environment you probably know about Junk Light. If you don't then let's start with the definition. 



Junk light is the over-exposure to artificial light at the wrong time of day that can aggressively inhibit your melatonin levels and the physiology of your eyes. Artificial light sources, especially LEDs, compact fluorescent (CFLs), computer, smartphone, and eReader screens are nearly unavoidable. These light sources amplify the blue, green and purple parts of the light spectrum.  Your body’s sleep-wake cycle, also known at your circadian rhythm,  is incredibly sensitive to this spectrum of light. When exposed to it at the wrong time of day or night, you end up with junk light, which impacts your ability to get quality sleep. Thousands of studies show that poor sleep leads to a host of other physical and emotional issues.



Now that you know what Junk Light is, let's get to what it does to you.

Junk light impacts photoreceptor cells in your eyes, and suppresses the natural production of of the sleep hormone, melatonin, which throws off our body’s internal clock, disrupting our ability to sleep deeply and restfully. Junk light also emits a unique glare that impacts your retina causing eye strain, headaches, and physical and mental fatigue.



Junk light may contribute to and, or be linked to many chronic health conditions, including but not limited to:

  • Eye strain
  • Headaches
  • Short-term memory loss
  • Problems sleeping, due to melatonin suppression
  • Stress and anxiety, due to cortisol suppression
  • Symptoms of Seasonal Affective Disorder or depression
  • Endocrine disruption and a poor immune system
  • Female hormonal/menstrual cycle disruption
  • Weight issues
  • Agoraphobia (anxiety disorder)


Not cool right? Now, more importantly. How to protect ourselves?

Here's a list of practical things you can do to minimize over exposure because, let's face it; screens have become fundamental tools for our everyday life so there's no question of stop using them, the useful strategy is to learn what to do to avoid getting affected by them. 

  • Reduce the use of Screens: As much as it fits your Lifestyle, being more aware about it will help you avoid wasting time looking at screens incessantly and unnecessarily. 
  • Spend more time in Nature: The reason for which we keep hearing this over and over its because it really matters, not only when it comes to Junk Light, there's a wide variety of benefits that Nature provides for us. Plus, its free and available. 
  • Change your LED light for Warm Light Bulbs: Here the options are, either replace your bulbs or get some filters to place over them to minimize exposure, this makes a huge difference. You can buy the filters here
  • Stop looking at screens at least 1 hour before bed: As it gets dark our brain picks up the natural signal that its time to get ready to sleep and starts winding down, just by looking at a bright light for as short as 3 seconds our brain gets a signal and it reduces or stops the production of Melatonin, (Our brain doesn't understand if the light source is coming from the Sun or from our Smartphone). A good alternative to prevent this is to restrict the use of screens before bed so we can get our Melatonin production in order as the time to sleep approaches; this will help us improve our overall sleep quality and if you don't know by now well... It`s a huge marker for our performance and health. 
  • Biohack your sleep: As science keep adding up study after study regarding the importance of High Quality Sleep a variety of Companies and product lines have been develop to help us with such matters. One of this Companies is called TrueDark.

They offer a wide variety of protective glasses to filter out Junk Light and allow just the right amount of it (We do need some). I highly recommend you to check them out, they have over a decade of experience and their products are really worth your time. If you know anything about Biohacking and its World then you surely know Dave Asprey, the founder of Bulletproof. Well, he's one of the investors and for good reason. If you feel like it check them out.
