This powerful video below is from the skylight company, Velux. A clever marketing angle perhaps, but regardless it's a confronting reminder of just how out of touch with nature modern life has become...

Skylights are a great idea for getting more natural, full spectrum sunlight into your home.  And to reduce the impact from 'happy screens' and modern lighting at night, our blue light blocking eyewear will make that closer to nature intended... Artificial lighting when received through our Mito500 lenses is more akin to sitting around a campfire than the over-stimulating "solar-noon" signal sent from screens and lighting. 

Get outside, get natural light, protect yourself from junk light.
