Using bright artificial lights or sunlight exposure upon waking can stimulate heightened levels of focus and the release of dopamine, norepinephrine, and epinephrine.

“If the sun isn't out, I turn on as many bright artificial lights as I can manage or tolerate and then I go get my sunlight exposure.”

“Being in a brightly lit environment can lend itself to optimal work throughout the day, not just during that early phase.”
