Great post deserves a vote
But take this a little further and you will be able to link be sleep to all sorts of diseases
The reason most people have horrible sleep is due to them using technology all the time (why you see it in teenagers especially)
I could write a whole blog on this (will in the future) but the major reason is that all these screens are using blue backlights
This completely screws melanopsin (https://en.wikipedia.org/wiki/Melanopsin) which is the primary controller for day and night cycles
Melanopsin controls the secretion of the hormone Melatonin
In general terms, this hormone is the called the "Sleep hormone"
When Melanopsin does NOT get irradiated with light in the Blue to the Green range it starts getting ready to use the Melatonin created during daytime
(https://en.wikipedia.org/wiki/Melatonin) most people have heard about it but no one really understand how it gets made during the DAY
It happens in the same places we find Melanopsin, the eye and the skin.
UV light gets absorbed my the "Bensen ring" in the aromatic amino acid (https://en.wikipedia.org/wiki/Aromatic_amino_acid) Tryptophan
Take a look at the chemical structuce of these types of amino acids
Does your computer smartphone or what not emit light in the UV range.. Nope
Are other hormones made the same way?
Watch Jack Kruse's talk from Nourish Vermont 2017 he will tell you even more about this
Sleep is really all about Autophagy and Apoptosis
Cancer can NOT happen when Apoptosis is working properly
Do I say that the higher levels of cancer is steeming from techonology? ... Yep
