CSD #1...RED-LIGHT DISTRICT |
No, no, no...
...get your mind out of the gutter!
Let me 'splain:
Anyone who was ever a student or educator in the windowless monstrosity at 4201 Sycamore (aka CHS, CJSHS, and whatever you would call it now that it houses the 6th Grade) KNOWS this effect to be true, whether s/he knew the science behind it or not.
From Education Week
Human brains regulate circadian sleep through exposure to short-wavelength "blue" light, which makes up the bulk of bright daylight. Short-wavelength light increases cortisol in the brain, which regulates alertness. As blue light during the day fades to the longer-wavelength, redder light of dusk, the brain's timekeeper, the hypothalamus, suppresses cortisol and releases the sleep-promoting chemical melatonin.
