The Problem With Blue Light
 
Studies have repeatedly warned that using gadgets in the evening affects both the quantity and quality of our sleep.
 
The cause is exposure to light at night time.  Or, more specifically, it’s exposure to short wavelength blue light-the kind given off by our phones and tablets and pretty much any gadget with an illuminated display.
 
Sunlight also contains blue light, and is vital during the day.  It is what helps to keep us awake and alert, and it’s an integral part of how sleep cycles work.
 
But exposure to blue light at night is a bad thing, as it effectively tricks your brain into thinking that it is still daytime.  It suppresses the secretion of melatonin, a hormone that is produced at night and prepares the body for sleep.
 
In addition, long-term exposure to harmful blue has been linked to increased risk of developing age-related macular degeneration (AMD) which is the leading cause of vision loss in adults over the age of 50.
