What is Blue Light Syndrome?

Informational

Blue Light Syndrome has been a big buzz word lately, and in the sleep industry it is even bigger, so what is it really all about?

First things first…your body creates melatonin. For centuries, when the sun went down and darkness set it, the human body would start creating melatonin.  

In our day and age, we have TV’s, computers, iPads, and mobile devices that create light long after the sun goes down. The type of light most electronic devices create is called ‘blue light’ and blue light is interesting because it tricks the mind into thinking it is still day therefore the body does not created the needed melatonin to properly wind down and get restful sleep at the end of the day. 

Studies have shown that people exposed to more blue light have suppressed melatonin production in the body that effects their sleep duration and sleep quality. See study information here: (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3786545/)

For those struggling with getting to sleep, staying asleep or non-restful sleep patterns, Harvard Health recommends these steps to avoid negative effects from blue light:

Use dim red lights for night lights. Red light has the least power to shift circadian rhythm and suppress melatonin.

Avoid looking at bright screens beginning two to three hours before bed.

If you work a night shift or use a lot of electronic devices at night, consider wearing blue-blocking glasses or installing an app that filters the blue/green wavelength at night.

Expose yourself to lots of bright light during the day, which will boost your ability to sleep at night, as well as your mood and alertness during daylight.
