Using bright indoor lights upon waking before sunrise promotes wakefulness via melanopsin, while dim lights maintain sleepiness.

“But, the interesting thing is if you start viewing light frequently in the morning, then those connections between the melanopsin cells and the circadian clock, become primed or potentiated we would say, they become stronger for the anticipation of light.”

“I think the best thing to do is simply to turn on as many Bright Lights as you can indoors to trigger that melanopsin mechanism if you want to be awake if you want to stay asleep or sleepy then keep them dim”

“it turns out that the connections between these melanops and cells and the circadian clock are plastic throughout the lifespan so there's an opportunity for short-term plasticity”
