Someone asked me on the Vermont 2017 video: "Why are sunsets so important to a mitochondriac?"
Answer:
Because the color temperature of PM light rises and this is the blue crescendo photic stimulus to the melanopsin/retinol system and signals the origin of activation of melatonin during darkness after its aromatic rings were initially excited by AM IR-A and UV-A light. This is also a big leptin and amylin trigger too for the same reasons.

 

Neurodegeneration is always associated with a sleep defect because of mtDNA damage that destroys melatonin autocrine production. This sets up the circadian cycle loss that destroys dopaminergic neuron destruction.

Sleeping less than six hours a night when you're in your 50s, 60s, and 70s increases your risk of dementia by 30%, a long-term study has found.

We are almost always in bed by 8;30pm but quite often wake up at 3:00am. we usually fall back asleep in about 30 -60min and wake about 5:30am.

This seems weird - I don't understand why we always wake around 3:00am?
But it does seem like we get enough sleep.

Is this okay for continued good health?
